I have an off-grid 400W solar kitchen assist system. Our house is on grid energy. I ran parallel wiring into kitchen so we can choose between grid or off-grid power by plugging into desired wall plug. It sends solar energy into a 3000W inverter that is secondary power for our kitchen small appliances. It can power the large refrigerator/freezer during the day but the 400Ah battery bank is not quite enough to power frig through night. Can a Supercap be used to inject power into the battery bank in early morning hours so energy in bank could hold up until sun shines to recharge system power?

[@dennisolsson3119]

I have seen people putting super capacitors parallell with a small RC battery in place of a starter battery. The RC battery provides power to the radio/lights/door locks, and the super cap handles the current spike on starting. Seems to work in the videos, but of course it limits the power available without the engine running.

[@ThinkingandTinkering]

it limits the power to the power you set it at by the size of your capacitor bank - but as this set up is really for peak shaving - the over all power shouldn't be limited if it is the cap bank has been wrongly sized

[@JaenEngineering]

This is similar to an idea I had but at a much smaller scale. The stability and efficiency of the grid relies on the supply and load being in near perfect balance. Too much supply and the grid voltage rises and things go pop. Too much load and the voltage sags and you get blackouts. One of the main problems is that the grid supply is slow to respond. It can take upwards of 30mins from the demand increasing to a power plant upping its output, so predicting when the load is going to increase is important. There's obvious times. 7am and people get up and stick the kettle on. (While one 1kVA load is insignificant, 10 million 1kVA loads on the other hand.) So here's the idea, have homes install "powerwalls" that can balance the demand at the load side, rather than the supply side. everyone gets up and sticks the kettle on, or there's an ad break just before a world cup final penalty shootout (so everyone gets up and grabs another beer from the fridge) and rather than having to predict exactly when the load surge is going to happen, the load side energy storage supplies the demand locally, and then slowly recharges over the course of the day while your out at work. Add in some smart metering so the supply knows how much has been used, and you can keep the grid in near perfect balance. Probably explained that badly, but I'm sure you get the idea!

[@RPRosen-ki2fk]

I like it, sounds like something RMS should do a video on.

[@colleenforrest7936]

Could you use that as a way to hook up power from different sources (solar and wind) to the same battery

[@MrBrelindm]

Most of the larger integrated solar charge controllers nowadays have connections for the battery bank (including individual cell monitoring), a three phase AC inverter (up to 25KW continuous output, and the ability to seamlessly charge from solar, wind, and even shore power or automotive or any combination of those at the same time. The Chinese have had them for years now. They are the innovators in this field. You can buy them online but many aren't yet UL listed so caveat emptor applies. But due to tariffs and shipping inflation they aren't as inexpensive as at first blush they appear. However, it remains that the technology is quite well developed already by the Chinese and there's a thriving domestic market for them.

[@MrBrelindm]

They're often described as a "solar inverter" when searching for them online.

[@MrBrelindm]

They are programmable with different power profiles. So they can easily be reconfigured for a battery upgrade - even if the cell chemistry used changes. They are quite versatile.

[@ThinkingandTinkering]

yes - several systems have been researched to do exactly that - have a quick look on google scholar with hybrid battery supercapacitor micro generation as key words

[@maxkennedy5073]

Bit of a different topic but same components. A lot of the concepts scavenge energy, relatively low energy. Can that energy be.accumulated by super capacitor then transferred to the battery even if the energy source has lower voltage than the battery? You mostly spoke of the supercaps leveling energy spikes.

[@garneau67]

Would it be feasible or useful to add a car audio capacitor to a basic solar power bank setup on leadacid? I have a system that runs a converted chest freezer fridge and the power draw on startup triggers the low voltage alarm when it starts. After the initial startup however it only draws around 80W or so. The car audio caps I've looked at range from 2-5 farad ratings. If it was hooked up parallel to the inverter would this provide the boost needed for startup of an inductive load? Thanks

[@elmerkilred159]

I'd have to know more about super caps to know how to apply them. Are they more flexible for charging? (Like trickle charging from solar panels, or extreme fast charging from daisy chaining solar panels). I know that the electric motors I have around the house have two capacitors. One is a run capacitor, the other is a start capacitor. I think my AC might run the same way.

[@diedericknaude4316]

Thanks ! Any remedy for Mecer ups which seems to be programed to switch of after 10 minutes ?

[@iami9307]

Robert I think that would cause more problems than it would solve. A capacitor wants to push out everything it’s got. A converter or regulator will take all that and turn it into heat and waste it. The capacitor May lesson the load on the windmill and trigger the braking system which is usually done by adding a load to the system.

Good Video. Just a quick question on inverters if any one is savy. We all know that current is only drawn when there is demand, ok so my question is actually do inverters have built in protection to limit there output. So say my home is using 2Kw of power and I have a small 200w inverter suplementing the house while drawing 1.8kw from the grid. What sort of circuit in the inverter protects it from having more than the 200w being drawn? Cheers if anyone knows.

[@ThinkingandTinkering]

I think it depends on your inverter mate - cheap ones - no - but more expensive ones will have current limiting as a feature - I would guess - but you really need a better answer and I am sure others on here have a better one - cheers

I was thinking about cylinder design, and besides making composites with graphene, couldn’t graphene ultra capacitors be used as Filler in an O Neil Cylinder? It should have sufficient strength, or you could design it with strength in mind, storing more energy than a battery made out of concrete. Using any other battery chemistry in a cylinder would necessitate it being replaced every so often. - It would be nice to just have a set and forget graphene ultra-capacitor that you replaced every 50 to 100 years. And for the flywheels story, most of the power, that’s just in the material strength.

Edit: If anybody has any advice on using solar and utility power concurrently, I would really appreciate it.

Lowest I've got is 6V with a push start (it is standard, not automatic). I have been wanting to use a DC-DC converter not to charge from a lead-acid, but to extract the useful stored energy below 6V. It's not easy finding a 200A rated 12V boost converter that can run down from 1V or lower.

In theory. The 8s pack should make it that low, but it never does. Both the inverter and solar charge controller warn to "NEVER DISCONNECT BATTERY FIRST OR UNDER LOAD FIRST". The supercap pack would not need to work long at all. It just needs to handle the high amps of charge/discharge, and to reach 10.5 vdc after lifepo4 shutdown.

It would be very interesting if Tesla would use a bank of super capacitors for taking all the power during regenerative breaking. Then split their battery pack into two sections at 400 volts each. The capacitors would dump their energy into the lowest voltage battery section, then that section would rest while the other section powers the motors. Both batteries would be used in parallel while under hard acceleration. When charging the battery sections would be arranged in series for an 800 volt fast charge. When driving everything is still configured for 400 volts. I wonder if the extra effort would make financial sense.

not much - this is really peak shaving and to cope with high power demand over short periods of time - like starting a motor - the start of a. motor has a very high draw the running of a motor much much less - you are using the caps to be in the middle of that and they are tied to the battery bank - you second comment was pretty good by the way

well, it's a bad idea. 1st: supercapacitors are quite expensive which makes more sense to just invest this money into more batteries.- this way we solve all the problems and have bigger storage too 😜. for 100Ah battery 20A discharge current is 0,2C which is suboptimal. for 2*100Ah (200Ah) 20A is 0,1C which is acceptable. 100Ah 12V battery is 50£ or 60€. and it will solve DoD problem as well. 1,2kWh from 100Ah 12V battery is 100%DoD. 1,2kWh from 2*100Ah 12V battery is only 50% DoD 😁 2nd: biggest sin in engineering: complicated design. DCDC inverter as a Single Point of Failure. 3rd: this design of yours doesn't solve anything. energy stored in this capacitors is not enough for any real life scenario's apart from EV's(rapid acceleration)
