They are now affordable- virtually indestructible- and very desirable
The Battery and the Capacitor pack are in parallel and the Inverter connects to the cap. The cap is taking all the start spikes each time a tool starts up so the battery gets an easier life and lasts longer. Another benefit is that all the heavy loads like vacuuming and workshop stuff get done during the day and your batteries are fresh as a daisy come 6pm when everyone is home and charging phones and watching screens.
Have you measured what the caps actually do? Because I have my doubts that they in practice significantly do what you say here. I put more details in a seperate comment...
I've done this for my off grid setup. A 2500W pure sine inverter, 760W of panels with a MPPT charge controller 300Ah LifePO4 battery with a hard current cutoff in it's BMS at 200A 500F bank of supercapacitors. Before I added the supercapacitor; The charge controller would often trip the BMS when topping off the battery It often tripped the inverter as well with an overvoltage, once, blowing up one of it's caps it didn't handle large surge loads, like starting up compressors. Tripping the battery BMS, the inverter undervoltage shutdown, and the MPPT undervoltage shutdown, requiring a jumpstart of the system After adding the supercapacitor; parked right on the inverter terminals No issue starting the compressor, even at night. It seems to give the MPPT time to adjust to the changes in voltage and loads, no more overvoltage shutdown problems with the rest of the equipment. On the rare occasion I do run the battery out in the middle of the night, the cap retains enough voltage to allow the MPPT to restart at sunup
Awesome Im so glad that you are getting the benefit from this- Our set ups are a very similar size and yes my big 2.5hp compressor is the beast to start too @@davidconner-shover51
my point is when paralel 2 bmses one for lithium one for supercaps . even if its sophisticated and sized correctly .. you neeed a third system monitoring surge and when it finds out rapid changes it releases safely some charge to stabilize it.. if there is shade and solar or grid cant stabilize the voltage difference . well i can smell the situation before it even happens!!!. !!!! in the end i agree its nice idea for supercaps if everything mades well
@@panospapadimitriou3498 In an off grid situation, Lithium batteries charge characteristics fairly closely match their discharge characteristics. Ie, they will take everything you feed em with little change in voltage. until they suddenly come back, and and say "I'm full,and won't take an electron more, vs Lead Acid, which will come back and say, I'm full, but will burn those extra electrons off in a bit of flatulence" To a MPPT controller, or a car alternator for that matter, needs some time (and a change in voltage as a tell) to ramp up or down it's charge delivery to compensate. No supercap in the system, that maybe 100+ amps it was shoveling out will pile up in the form of voltage, a lot of it I've seen first hand what can happen to a system with one of these batteries without one. smoking heap of fried electronics.
How dare you assume that I am intelligent?
I am sorry, please forgive me, I will try my best to never do that to you anymore. A thousand pardons for my transgressions.
Hey!! You shut yer fu**in' mouth when you're talking to me!! 😂
I've been thinking about this for awhile. Thanks for doing the research for me.
Oh dear!- I do wish that you 'classically educated' electrical engineer types would open your minds to accept things that are outside the accepted paradigm. My upcoming vid where I actually utilise these supercapacitors will show that In my intended use, They protect my small pack of lithium batteries from stress. They are NOT A REPLACEMENT FOR BATTERIES. The wankers who comment below that they are not suitable for my intended purpose - Do not yet even know what my intended purpose is! Also - they conveniently ignore the part early in the video (5:26) where I describe - In terms that a 9 year old understands. What I am using them for. - just so that they can expound their extensive knowledge on the subject.
@@jirisirek1701 Try not to think of them as a batter replacement- they are a battery saver. they will help your batteries recover faster and make use of excess charge during the day
@@jirisirek1701 you may say thats not an answer but it was a stupid question in the first place, why would you be asking him where to buy them from? he is in a different country from you so his price may be a good price or a bad price since you have to take shipping cost into consideration. And you dont compare the wh to a battery wh
@@jirisirek1701 I think you missed the point of the supercaps, let me give you an example, if you had an 800w inverter (the ones they sell as 2000w) it will run your circular saw on a fridge but the initial surge would exceed the battery/inverter but if you had some supercaps just to supply the inverter for this surge then the fridge or saw would work. you mention lfp these have great power density but due to internal resistance have poorish current surge, this is one of the reasons why tesla bought max caps to use in their current lfp cars, the cap is only needed for that surge of current when moving off or speeding up plus they are better than batteries when regen braking. Ive seen where people says they have replaced their car battery with supercaps but we all know this doesnt work and is just another clip bait video
People know shit about electronics, wattage, amperage, talking thousends of Mah whatever THEY might think it is.. digital foundrey, linus, 99 repair channels, all leeks in disguise… there are some things batteries not like, and super caps could “smooth” out the work for the battery to deliver, thank you.
@@ClosestNearUtopia I come into the comment sections from time to time on videos about caps just to laugh at boomers who are 110% sure about something they barely understand. the amount of people who are openly advocating for EV's to start using supercaps to even out their charge/discharge cycles. make them king for a day and i would hate to have to be the person that tells them: all EV's and hybrids already do use a bunch of super caps otherwise their regenerative breaking would work lol. its like this swarm of boomers go in phases in the yt comment sections, in early 2000's it was about over unitity/free energy, now its about electronics and charging. if only they went to univeristy and learned the difference between energy density and power density... instead they just go around saying stuff like "college is a scam" and "nobody wants to work anymore". okie dad but ur on social security and keep asking me to help with really elementary stuff like how to calculate the length of a roof's hypotenuse
Thanks for the info
A few things. There are A/C and D/C caps-- they are not interchangeable. A cap resists a sudden surge of voltage whereas a choke or coil resists a sudden change in current or amps. In a/c circuit caps are used to perform power factor correction. This relieves the power supply of producing surge power -- and this prevents voltage drop which can cause your lights to dim when your air conditioner, for example, draws compressor power. Caps in part can be used to convert A/C - D/C. Caps can deliver a lethal charge to a human, they oft have sharps on them and this can deliver output under your skin-- and should they suddenly discharge under your skin, this can kill you.
16 volts DC will not do anything this is why i can touch the terminals on a car battery and nothing happens
@@punker4Real you will feel a 16volt max surging a/c or a not fully rectified d/c current. try this start the car, get your hands wet; your bare feet on the ground, and then put one hand on each terminal of your car battery. you will be in for a real surprise. And this is only 13.5 volts.
@@heyhandersen5802 You watch too many Hollywood movies This isn't homealone 2
Hahaha Thank you so much. Have a great day
Hi Mate, just wanted to see if there was an update for this project? Cheers
Good one mate there are some things my solar inverter 3kw won't start air comp now I know why cheers
Glad I could help
it's called a starting capacitor....just like on air compressors
the bms for the capacitor bank, do u need to worry about buying the right 1 for the high amps?
Can you show how you installed it on your system in conjunction to your battery bank.
É um problema utilizar os super capacitores em serie sem um Balanceador?
this is a really great video. thank you for this. reason i looked at it was... im interested in getting a super capacitor power wall that is 10kw in size, would be really cool if you could talk about that in a similar vain to your video here as i believe there is very little video content that talks about it.
I will do that. Its a great idea. But I'll not be building one. Itll cost so much and I dont actually need it. Thanks Ashon.
I wonder if this will work for something I am trying to do. I just had some lead acid batteries start to die in this older APC UPS i have its 24v, so I ordered some 24v lithiums and they have not arrived but I was thinking about it and now im worried that once the bms hits 27. whatever voltage its going to cut off the batteries and the apc ups is going to freak out i imagine anyway so could I put a bank of super caps between the new 24v lifepo4 battery and the apc ups to like act as a pond/lake but all current would flow through the caps etc if the ups runs on battery if that makes sense does that sound doable to you?
Looking forward to installation. I have been thinking about something similar. Could see how the individual cell voltage protection is working on this?
Its nothing more than individual voltage level activated switching
I have enjoyed your video. I'm looking at a couple of 2nd hand 3.55kWh 48v (7.5kWh) Sirius kilowatt industry units. These were being used as a stand alone power unit with 10kw from solar. Could these be used for use in a motorhome with 2200w of solar panels. Thanks for your informative videos
2200w of solar is a bit greedy isnt it? haha- what on earth do you do in there? 7.5kWh is plenty of redundancy and your 2,200 watts on the roof will charge them up in no time- all 'gut feeling' rather than number crunching at 10pm on a Sunday night. I hope you are having a great weekend?
I wonder if you reduce the vapour permeability when you hit them with heat and they shrink? I bet it reduces if not stops altogether. Interesting.
Can I buy this bank or do I need to build it my self ?
Does anyone know? how many capacity in farads does an array of capacitors need in order to start a fridge? Thanks a lot!
Around 6 years ago. A friend flattened her car battery and she called breakdown service and he was testing a super cap jump pack. He hook it up to the battery and said the battery was 8v and he could use it. I talking with him and showing how it charge each cell if the jump pack. Took a couple minutes. He said you only get one go with it and have to recharge. As it was new car, started straight up. Any chance u make video on ur battery and how U wire the super caps in, cheers
Im thinking of something similae
Just to recap 😂👏👏👏👏 Nice one 👍
You are the first! - took so long...
I would be really interested in how you install this into your solar power system. Is there a dedicated charger for the super caps or are they in parallel with the battery and get charged by the same mppt charger that charges the lithium batteries?
Yes - the charger just recognises it as another battery
I park mine directly on the inverter feed terminals. looks like a 6 pack of beer atop the inverter
In high end automotive audio systems with large amplifiers, there are capacitors in use in the range of 1.5 farad capacity and upward. Would a bank of those be useful for off-grid power?
no good at all- super caps are 600-1000f capacity while the voltage is low- they are pretty much the opposite of ordinary electrolytic caps
@@t.h.o.r. Good to know, and thank you for the reply!
These 1.5 farad capacitors have got 6 small 2.7v capacitors in them so it looks like just one package but costwise you're better off buying the individual caps, 1.5 farad would be about 6 * 10 farad in series I guess
I don't know which barrier band or type you a using exactly but if that's the same stuff we have here in Canada then those packs you made are not water proof enough. It is just waterproof enough to avoid mold and even then it's not perfect if there is continuous moisture. You may also want to something under the packs but inside the barrier incase there is pooling moisture or some silica gel packets to capture any unwanted moisture inside the barrier. It also becomes very brittle from cold weather and UV. Cold weather may not be an issue for you as much as humidity and UV. That stuff shouldn't be used exposed to the elements for things as sensitive and potential deadly the next time you touch one imho. If they never get direct sunlight or rained on directly or indirectly I think it would be fine but not indefinitely.
I was curious if you can wire 4 of those modules in series for a 48 volt system? Would the first module explode when the 53 volts from my charge controller hits it, or would it be divided equally between the 4 modules?
No explosion if you buy the right module for your voltage. then just build a brick to suit your requirements/wallet/ space available. there are dozens of variants on e bay
Hi there, I’m based in Christchurch- where did you get your super-capacitors from? Do the circuit boards with the capacitors control the charging of the capacitors?
Hi PB Tech have them if you want now- If you can wait 3 weeks you wiil get great deals on E Bay as per the link in the description. the board is a charge controller it limits the charge and discharge- same as a BMS battery managment System in all lithium batteries
havent seen any follow up vid of this if its working
Regardless about the curent that supercapacitors have for instant consume... Olso helps in the charging more efective, helthier and fast. Isn't it?
After watching the video twice I understand it's purpose and how it works but I'm unclear on how you would hook it up. Do you just piggyback it to your battery bank, + to + and - to - ? Or does the super capacitor need it's own charge control?
Yes - the charger just recognises it as another battery
My understanding is that these lose something like 30% of capacitance per year if held at ~2.2V (out of 2.7V max) continuously at room temperature. Have you experienced this effect?
Ive had them for 4 days mate
You can help an inverter work better by using a supercapacitor array in parallel with your battery pack. They can provide thousands of amps impulse current ❤
Yes!- this one I built is now in daily use alongside my lithiums in my small solar system. when my pump turns on there is a 16 amp draw. the batteries used to drop to11.9 v- now they only drop to 12.7 while it runs. Its pretty much the best money I spent on my budget system. Thanks for reminding me- Ill do a video on it soon
Im so sick of youtubers starting the video with complimenting the viewer. You cant even see us and you dont know us so it is the purest form of being disingenuous.
Elec Eng here - I understand exactly what are trying to do, but I don't think you are doing much of it if you are just putting the caps in parallel with your batteries. Video was so drawn out I can't be arsed watching again to confirm my suspicion there. However, why wouldn't you fit them with a diode in series to give them a preferential drawdown by being at one diode drop higher? (or there are more complex arrangements, but either way you maybe you would like to avoid a permenant diode drop in your system). Or in a more complex system maybe feed the caps in where a generator or outside supply might go into your invertor and make sure you set up to charge the supercaps a couple of volts higher than battery voltage, as high as they can go and system can take really, as you probably only get to skim off the top of any voltage over the battery voltage, and if directly parallel thats not much. Or if you can preference that feed in down to a certain voltage in the inverter settings maybe. At the moment from what I can tell they are just in parallel with the batteries so will only supply until their voltage drops, which it will do in line with the exponetntial decay of a capacitor - standard equation. The batrteries on the other hand, unless really hammered super hard will only drop their internal impedance until charge starts to deplete, which is a long time usually. If it is a direct parallel connection then it becomes a sharing exercise with the batteries based on internal impedances in parallel and as the voltage drops, and as I have said it will quicker for the caps than the batteries, you only get a portion of the stored charge working for you. Might be worth running a PSpice model and modelling to see how much actual contribution you get from the caps, but I think not much without a more sophisticated arrangement. (Note: the use of supercaps in car audio is usually to put them closest to the amp as possible, to negate the effects of sag from volt drop on the wires, car batteries have plenty cold cranking amps but no one really wants to run 120sqmm plus power cables to their amp, so the supercaps. If you are converting the DC to AC, then you cant put the supercaps directly at the consumers terminals where they might have best effect, so unless you have DC loads and you can move the caps there, I am not sure you are getting the full benefit you are paying for)
can you limit the amperage and make them more general purpose?
You do not have an understanding of how electricity works. Think. if you connect a tiny instrument cluster illuminating bulb of 2 watts to a massive powerful truck battery- Does the bulb blow?
sounds like the surge modes some inverters already have !!!!! btw paraleling super caps on a lithium system . its hard to maintain power from solar only there will be for sure surge between lithium pack when there is big voltage difference!!!! . and solar has to be enough to maintain and stabilize it as fast as it can .. !!!! maybe an automatic secondary super cap system with relay can help it regain before surge destroys or hurts and lowers the life span from lithium pack or electronics of both packs
This is a good informational video... the guys voice and constant volume changes... think he needs a capacitor to even out the volume leveling just a bit... hahaha
What is the downside vs batteries. Do they lose power over time? If you charged up the bank you created, what would the daily loss be if not being used for anything? (I know you aren’t trying to use them as a battery, I am curious about the losses to understand better their use in smoothing out battery usage that you are talking about - what is their efficiency?
mine lose about 0.1v per hour so they are useless by morning- but they charge up again in 120 seconds of direct sun on 500w panel. they providse a buffer zone for your batteries when you run high loads like big skil saws or compressor
My idea is to charge a small number of supercaps in a 12v cluster so that they will power a 12v tire pump for a minute or so. The idea is that the panel takes a while to charge the battery (5 mins) and this gives the pump time to cool before its next 1 minute stint as it brings an air tank up to 120psi. I can then use that small air tank to put air in my 100psi tires.
real lightweight and can be mounted anywhere- great for airing up big tyres after a muddy session.
@@t.h.o.r. That's my thought anyway. I had been puzzling over how to control it all and then realised one of the cheapo 12v PWM lead-acid solar charge controllers would work perfectly well to charge the supercaps. A 16v supercap setup need not be charged to 16v. The advantage is if I have a 16v supercap array, charge it to 14v (or whatever the charge controller does) then the charge controller cuts off at 11v, the motor gets the power sweet spot.
I was of the understanding the capacitor was used to relieve the 12 volt batteries on initial draw made by the inverter.
I hope you will feed us back on the delivery in the future.
Oh yes- I built this as part of a portable powerstation project- you will see it all shortly
@@t.h.o.r. thanks in anticipation 🙏
Slight correction! supercaps have been around longer than 10 years, we use to use them for real-time clock power in XT computers back in the 90s
really?- I bet they cost a fortune back then? Odd that a supercap was used to power a low drain device like a clock? I would use a silver oxide battery or a conventional capacitor myself. even in the 1990s. maybe it was just marketing wank that Dell and GE used. I remember my 486 and dialup modem fondly.
Ive seen so many who uses electrolytic capacitor instead of supercap with their solar batteries, like for example one piece of 50,000mf 80volts does it have the same effect or its just useless?
Useless, just as this one here with supercaps. They hardly do anything because of physics. Every cap (both supercaps and conv. electrolytics) linearly drop in voltage when you draw current out. Farad is (A*s)/V. A cap with 1 F drops 1V if you draw 1A for 1sec. Batteries hardly drop at all in their proper range of operation. So the batteries do pretty much everything because the rail does not drop in voltage and the caps cannot contribute anything relevant. Save your money for a bigger battery and ignore this capacitor quackery.
I'd like to see a step by step on building the super cap pack.
It really doesnt warrant the effort- Its just join as many of these positive to positive as you can afford with heavy gauge wire and ensure that nothing can short out. Then connect to your battery bank.
@@t.h.o.r. it was more about how to wire up the BMS to it.
@@StonerSmurfin they come on boards already wired. 6 in a row. you just connect +to +
My solar system uses 2 GEL batteries would it work with them or do I need a lithium capable charger?
the chemical type of the battery is not important- what is the voltage of the system? you simply configure the strips into the voltage you need by adding in series- then add as may of those units together in parallel to get your amps up to where you want them.
@@t.h.o.r. I use 12 v. Thank you for taking time to answer my question.
@@t.h.o.r. Just wondering. If I add a wind generator to my solar system, can I then connect the 12V from the charge controller on the wind generator, to the cable going from my solar panels to the solar charge controller? Or will I have to buy a hybrid charge controller?
When you say "your batteries take hours to charge" are you talking about legacy lead acid batteries? If so what you're saying makes sense, but if you've got or had any experience with LiFePO4 that's just not the case, they'll suck up anything you can throw at them from panels without even blinking, none wasted.
I share the fascination with supercaps, but sadly.... I have to disagree on most of what you said the caps would do in the various cases. Have you measured what the caps actually do in your system? I bet it is almost nothing. If your battery is not really tiny (or you run them in a very unhealthy high voltage what should always be avoided in general) Supercaps cannot take a serious piece of the load. Caps linearly drop in voltage when you take charge out of them. There is no "plateau-phase" like lithium batteries have at 3,7 or 3,2V, depending on the variety. And for maximum lifetime you always should run the batteries close to that plateau. +/- ~0.3V. What happens if you have caps in parallel? The caps want to drop and the battery does pretty much not. Who delivers the current? Almost everything comes out of the batteries in every case. So you are better off cutting the caps and getting slightly bigger batteries for the money. Maybe it makes sense if you only have tiny batteries that you keep at 100% state of charge (what you should not do in general!) and you have very spikey loads in the Milliseconds range...

9 year old classmates, the girls, where so much smarter than me
If you carefully design system addition to regulatory capacitor can increase solar or battery up 10 time normal power like buffering power then trig6charge it it can maintain charge all the time and add on double side ccd camera array you can charge battery even in darkness
would be nice if someone can do comparison charging lithium battery on solar with and without supercap, i wonder which setup can charge more at the end of the day.
I think you give the PCB which forms the bank way too much credit! 😂 It's a passive balance protection board at best. There is no over current / under voltage / short circuit / reverse polarity protections. There's not really any over voltage protection either. All they do is try to burn off power as heat on individual capacitors so that the risk of over voltage during charge is reduced. This relies on the overall input voltage being in range. It won't really protect from over voltage if you provide a voltage source which is well above the rated voltage. (Like 18-20v supplied to the 16.2v bank). The passive "balancing" won't be able to cope with that over-supply and they will burn out. To make things worse, these are parallel to the string of caps and thus even if they burn out, it won't interrupt the circuit, you just lose that balancing, leaving your caps more vulnerable. A legitimate BMS will genuinely offer all of these protections.
I noticed my supercap is swelling on the bottom, why is this?
overcharging- no protection circuit- They dont chernoble like a lithium battery will - but they will release their charge spectaularly- Im sure 'Electroboom' has a video of this. Bin it before it does some damage is my advice- and dont charge without a voltage cut out.
the word you are lookig for is 'buffer'
yes mate look to it all simpler because it is it only doing his work on a other way. forget this bms it can only handle its voltage the most are 50 volt if you go to serie with 50 volt the volts will go up even if you deal with 50 V that can run only with the first battery in serie. i know this looks like shit but there is a lot more behind it.
Wondering how and if a 48 v pack would do in my 48 v lifepo bank hmm
You will do what I did but configure the strips in 3s to add up to 48v or 4s to give 64v and just let you controller deliver its 50v max, I hope that makes sense?
@@t.h.o.r. yes, just like setting up my pack, difference is it's a a whole lot smaller. 😉
energy 1/2 c times v squared
I really hate that super capacitors are only 2.7 volts, wish they came in 5-6 volt versions.... The caps would work even better if we can charge them up to panels voltage not the battery voltage... And we need a buck/boost amplifier on them....
"Just to recap..." Ha, I see what you did there.
Also, i enjoyed the Welcome Back Kotter still. The Mogwai was cute too
In worst case caps make about 4,32MILLION cycles a day, for YEARS. Dont believe me? Well netfrequency*secondsMinute*minutesInHours*HoursInDays=Cycles and that is quite normal in some instances, like powersupplies or how about communication filters😮
A supercap next to a "real" battery does nothing. If the battery is way way to weak for the system, it does help.
Grazie Amico ma i supercondensatori hanno un prezzo altissimo
1st viwe
wow hello from Estonia! looking at this knowledge sharing video and got an idea. have a dirt bike conversion at hand but i haven't finished it yet. its a 2016 Husqvarna TC125 frame with a 72v 3000w 4speed clutched electric engine. still have to figure out the battery pack, lights and other small electric components and the charger still needs to be sorted out. me more like a mechanic type of guy. i dont know much about the electric stuff and a bad case of ADHD its hard to learn by my self. i probably need to find someone with electric know how who is a pal to help me out. but to make it easy for the electric guy.. have a couple of questions about my idea for a supercapacitor hybrid battery pack for my dirt bike build. if it is possible at all.. so if so then what kind of bms to use and does it need to be a separate one (2x bms), does the re-gen option work with supercapacitors or a hybrid back.. and the external charger issue that i have.. and what kind of charger do i need for this hybrid pack so i don't burn all of it down or blow it up..? for the battery to build the pack i chose the SPIM08HP 3,7V 8AH cells to make it a 72v 8AH unit. the cells specs: Internal resistance: ≤0.8mΩ. Max charge rate: 120A. Recommend continuous discharge rate: 200A. Pulse discharge rate(3 seconds): 400a. Fully charged voltage: 4.2v. Discharge cut off voltage: 2.5v. Cycle life: 2000 cycles to 80% capacity at 100% dod under normal temperature all the best!
Wow that's quite a project. I would love a little lightweight MXer again. I recently rode my mate's Suron - I think that it was 3kw and it went well- but not as good as a 125. I dont think Ill be any help to you though, this was pushing the limits of my sparky know how. It does seem to look after my expensive lithiums though when I run big loads.
@@t.h.o.r. well at least i got the idea from your video.. that was help enough. asked around today and got pointed to the right direction with the supercaps hybrid battery pack build.
"Remember I am trying to explain it to you like you're a nine year old girl", I assume you mean either that, or 21 year old man :-)
Lfp doesnt turn to poop if you leave it in the charger. It does degrade but very slowly, slower than 1cycle pr 24h according to a test i read where a scientific team held a bunch of lfp at max charge for 9months. Nor does my pv charge more if i use a cap, nor can my pv even theoretically charge more than my lfp can handle. 2/3 thru the video and guy just blablabla about rubbish with no actual reliable information.
Automotive audio caps are cheaper
hello yeah lol 1supercap egal 1/90 of a aa battery .. enjoy of ur day XD
Wakey wakey!- they are not batteries, and they are not doing the job of batteries.
@@t.h.o.r. yeah ok XD its made to absorb a peak current either in or out... nice u canot crank ur fridge peak current of ur old battery ... yup i know XD dont mess with those shit take a 12volt condensator for audio system ... they hold enough charge for the half first turn of ur fridge etc... hope u plugged ur directly at the connection of the onduleur they must be as close as possible from the load..
This video is mind boggling... though probably not n the way you might think! Viewers should be aware that this video gives a lot of information that may be misleading or not "entirely" accurate... eg suggesting that they will be useful in a home offgrid solar system for toasters and vacuums...etc. Supercapacitors hold a very small amount of power (1 has less than a AA battery) - their value is in their ability to discharge energy rapidly. - Lithium batteries for example store about 10 times the amount of power than a supercapacitor, in weight terms An ideal use for a supercapacitor bank is for jump starting cars - they need to deliver a bit less than 1Kw of energy to spin the car engine fast enough and power the ignition etc for long enough to start (or not start) the car. Don't count on much more than 10 seconds of starting power in a supercapacitor jump starter though. They are useful to deliver sudden power for devices with high surge requirements - like the chap's air compressor, or an air conditioner..... only for the couple of seconds required to get things moving (compressors being very demanding in this regard). This is because such devices require much more power in the initial second or two than their normal running rating. They would serve no purpose for continuous high demand appliances like a microwave, toaster, electric jug, vacuum etc. There is no power demand spike in these appliances, which simply require steady high power, which is something a super capacitor can't provide. They would struggle to be useful with a washing machine on the reciprocating cycle after the first couple of twists, because they wouldn't have recharged before the next twist. Remember... super capacitor stores a very small amount of power (like an AA battery), but has the great ability to release all that power in a few seconds which is what a battery can't do. It takes significantly longer to charge a supercapacitor than to discharge it. Some lithium batteries have a quite high ability to deliver instant power such as those used in radio control helicopters and such (the "C" rating, which is a measure of how much current in amps can be delivered by the battery, as a proportion of the total battery capacity. Such batteries are also used in miniature car jump starters. These are likely to have a rating of 30C or more. The video chap tells us he uses lithium batteries in his standalone solar system. A typical home solar lithium battery would be 12V with about 100Ah capacity, giving an overall total power capacity of about 1000 watts (1Kw) if fully drained. A typical home solar lithium battery is rated at 1C, which means it should drain at more than 1000 watts (a hot water jug typically being about 2Kw, a toaster perhaps 1.5Kw, a microwave (input power) being about 2Kw (microwaves are always rated at cooking power, not power required. They are inefficient critters so need more power than you think) Small air compressors are about 2Kw, 15A compressors are 3Kw. Moderate air conditioners use between say 750W and 5Kw (remembering that reverse cycle air conditioners effective heating or cooling power is significantly greater than power input... COP and all that (exchanging heat with outside air rather than actually creating it by resistance effect) The devices in this paragraph require much more power to start, because they are spinning a compressor from standstill. That's why most have a "starting capacitor". Been around for ages, does the same job as the supercapacitor role described in this film but not as well. I respectfully suggest these are they type of appliances which can benefit from supercapacitors. Feel free to shoot me down for anything above being inaccurate... but I suggest this video of an interesting experiment is likely to lead any viewer to think that what is presented in the video is a tested and proven enhancement, rather than an experiment that the Mr Tinyhouse indicates in a comment below he has only had the supercapacitors for a couple of days. I can't understand the statement that the supercapacity bank costs about the same as lithium. They are different things performing an entirely different function... it's like comparing the cost of a toaster to a dog kennel to decide which is better. I do look forward to viewing subsequent videos on the project, but hope viewers don't get excited and start buying up supercapacitors thinking they are going to make a standalone system wonderful.... before watching followup videos
Awesome comment!- thanks for such effort. Im not arguing at all. I diddnt realise that I was ambiguous in my description.
I noticed that no one came forward to shoot you down but In the video near the beginning I'm sure he said he was using it for wind, I must have missed where he changed it to solar, "They are different things performing an entirely different function... it's like comparing the cost of a toaster to a dog kennel to decide which is better." what he is doing is well known in the battery world, if you have doubt do a search for Supercapacitor and lead-acid battery hybrid.
Not worth the cost or hassle. There is a reason this isn't used in reputable solar companies. Just add another battery to the bank or upgrade the controller. Until they create graphene capacitors the efficiency is not satisfactory.
