WARNING! 2 things terribly Wrong with this capacitor/inverter setup! 1. The 150 Amp Thermo Breaker being used is too weak! Everyone MUST understand that for every 1000 watts of 120 Vac produced by the inverter, the Inverter draws 90 Amps of 12Vdc Battery power, so for a 3000 continuous watt Inverter, it needs 270 Amps 12Vdc battery power. So with that being said, a 3000 watt Inverter needs a 300 Amp Breaker. 2. NEVER EVER place the capacitor After the Breaker! The premise for the Breaker is if the Inverter Shorts Out the Breaker will stop the flow of energy to stop risk of fire. With having the capacitor after the Breaker there is No way to stop the capacitor from discharging over 1000 Amps into the shorting Inverter virtually guaranteeing a massive short and subsequent FIRE. Hope this helps everyone.

I'm using solar & battery bank to pump water Into a crawfish pond every day. The inverter runs the lifepo4 batteries down then goes into low voltage error, while the chargers then can't recognize the 24v batteries as 24v batteries. I solved the problem last year by using a small digital relay that shuts off a larger in-line ac relay to turn off the load instead of the inverter when the bank gets 1v low. That way the inverter never goes into error mode.and the batteries are still recognized properly by the charger. Did adding capacitors eliminate the same problem?

great and informative videos, could you drain your caps with the inverter? just have a small load going(a light)or two and disconect the batterys till it turns of? even a light straight to the caps, i dont like the idear of a piece of metal? just my thoughts.
@rhandsom

With my system I can't drain the caps from the inverter because the inverter shuts off at 18v, which would still leave the caps dangerously energized. You could use a light directly off the caps, but ultra caps have a lot of power to discharge so it may take awhile. In my case, the solid steel plate metal simply acts as restrictive load or a dead short. A light would appear to be safer, but the steel bar works well also, if precautions are taken. When discharging with a steel plate or heavy duty resistor, heavier gauge wire is an absolute must.

The balancing circuits and super capacitors itself have a amperage limit on charging and discharge.. a metal bar or big resistors put a lot of stress in your system.. I think patience is a better approach

Very nice. Did the addition of these caps solve your voltage sag condition ? I'm asking because I have a situation where when I start my 2 post hoist (2 hp 240V motor), it causes enough momentary voltage sag that one of two computers shuts off in the house. I've investigated the possibility of increasing the size of the 'start capacitor' on the 2 hp motor, but 2 different sources tell me it probably won't work as the caps are sized specifically to the needs of the motor. Sounds weird huh. I would think adding a cap in parallel with the existing cap would give the motor a starting boost. Perhaps I'll try it anyway. But I'm very curious how this capacitor bank has helped your situation.

The capacitor bank has worked out nicely. I have a video on my channel that shows me running the washing machine, 2 ceiling fans, a dishwasher, big server computer, and big screen TV at the same time, along with the fridge, lights etc. The ultra caps take the load and the batteries recharge the caps, 250 Farads is a lot of power (3000F each / 12 caps). However, if my battery bank goes down to just over 20v, then all bets are off, the battery bank voltage is too low at that point. But up to that point, the caps handle the surges with no problem. I was a good investment for me. Here's the video I was talking about. kzitem.info/news/bejne/o5unq21riIBoi3Y

No problem, it's a learning process. I've seen in the car audio videos where they would simply run negative to chassis ground so I'm hoping that tying the negatives to a common bus bar point works equally well. Are you suggesting that I tie the inverter negative to the caps as well or will connecting them to the bus bar be sufficient?

How did you determine the size of the capacitor bank? There doesn't seem to be information available. I have seen the car audio caps in the 1 to 5 farad range being used for solar. Which is minimal compared to yours. There is a 12v pre-built bank with 350f caps (not maxwell) on ebay for $60.00. The best bang for the buck. Still, I like to do the math.

I have a unique setup in that I have a 24v based system, however I'm using nickel iron batteries so my charging voltage is higher than lead acid batteries. So the math I used was, Maximum Charging Voltage = 32v, Each ultra-capacitor = 2.7v at 3000F, 32v / 2.7v = 11.9 or 12 Ultra-Capacitors needed. 3000F per cap / 12 Ultra-Capacitors = 250F total capacitance, that much stored power is more than enough power for household motors even well pumps. According to the datasheet each 3000F 2.7v capacitor has 3.04Wh of stored power. 3.04Wh x 12 = 36.48Wh total. The short circuit current potential of these caps are 9300A, so safety first is a must. It's also a good idea to get the over-voltage protection circuit boards and strapping plates to connect them in series. Hope this helps.

There was another viewer with a similar question so I'll just paste the answer with some additional info for you. I have a unique setup in that I have a 24v based system, however I'm using nickel iron batteries so my charging voltage is higher than lead acid batteries. So the math I used was, Maximum Charging Voltage = 32v, Each ultra-capacitor = 2.7v at 3000F, 32v / 2.7v = 11.9 or 12 Ultra-Capacitors needed. 3000F per cap / 12 Ultra-Capacitors = 250F total capacitance, that much stored power is more than enough power for household motors even well pumps.

It's also a good idea to get the over-voltage protection circuit boards and strapping plates to connect them in series. However, capacitors and power dense not energy dense. Power density means that power (a lot of amps in this case) can be released very quickly, Energy density means that a lot of energy can be stored and can be delivered over time in regulated quantities. Capacitors having high power density and low energy density are designed to compliment storage batteries that have high energy density and low power density. Running an inverter off of capacitors can be done for a very short duration and is not the ideal scenario. When charging the caps directly from my NiFe battery bank, a "huge" amount of current is flowing into the caps, enough to burn up wiring that is less than 4AWG, at 8AWG (typical jumper cable wire size) the wires get dangerously hot. Also, thanks for you comment.

I got the caps from www.tecategroup.com, I have (12) Maxwell Ultra-Capacitors that are 2.7v each at 3000F each, they are connected together in series to form a 32.4v capacitor bank at 250F total capacity. You can also get ultra-capacitors from AliExpress. They are similar in size to a soda can and aluminum construction, so you can't use copper lugs.

Hey Rhandsom, I have the iron edison batteries in 24v configuration like you have. I was wondering why you put the capacitor bank on the batteries vs. putting a higher capacitor bank on the 120v side near the electrical panel. I'm considering doing both, to help with the sag associated with my refrigerator(s) that kick on and off-- dimming my lights in the house as well. our channel is: kzitem.info I'm trying to understand better how your system is wired in this video. Any diagram by chance?
