Remove the balance wires and set the cell count to 1. Then charge. The voltage range is narrow, probably 3.6 to 3.65.

It definitely does support a single cell: Air8 support 1~8S Life, Lilon, Lipo, ULiHv batteries, even includes the ULiHv battery with...

I run 24V DC server fans in conjunction with DC water pumps for a solar swamp cooler. Also have a server fan to help RV propane fridge...

The experts have chimed in on similar scenario (still a guess that this is your issue)...

1000Ah x .7 / 4A = 175h (7.29 days) When did you start?

Agreed but a little 8Ah cell (8Ah x 3.2V = 25.6Wh) may not last long with a BMS, especially with bluetooth or other connectivity...

First off, I'm not qualified to give a definitive answer. My guess is that someone who knows will chime in with a solution that may...

Yes. I have a couple ISDT chargers so i think your Air8 can charge a single cell. Charge the one cell to about 3V and the Air8 should...

I think he's asking whether your generator's neutral is bonded (connected) to the ground (green wire connected to a white wire or bus...

Do you have access to the cell voltages? I'd bet one cell drops below the low voltage cutoff and the BMS cuts out. This does not...

Click on the link in my signature, there are more goodies in there. They were not created by me.

Definitely! Consider it just like any other 8x 240Ah cells combined to make an 25.6V battery.

4000W / 375V = 10.66A This says 10Awg copper (standard solar wire) is plenty...

How many volts, amps and what distance is the wire run?

You've heard of "FU money". This is FU power:

More munging to see what raising voltage more does... Make 3 2P pairs. 20V 10A Put these in series with both 200W panels: 100V 10A...

Lets munge with array numbers. Make 2 3P pairs with 100W panels. 20V 15A Put a 3P pair in series with 200W. 40V 11A Put 2 of...

Your 8P setup was 20V: 20V x 15A = 300W <---- there is your number! The array config i recommended is 40V so that would be limited...

The amps are pulled by the Delta Pro so it should only pull what it needs (15A max). Besides, you've had this connected 8P with 52A and...
