Will do thanks.

I hadn't thought of the 2. Mmmm

Here's a vid. When the clouds come over it drops as the battery bank is under load. But why this poor little lifepo4 cell is suffering so much? Or should I say appears to be.

I have a 16s Lifepo4 bank. Overkill Solar B.M.S. Sunny day with clouds, battery bank is full so I turned on a 2kw blow heater to use the free energy from the sun. One of the cells (On the app), the one that seems to go up and down more in voltage than the others generally and is always the one...

Thanks for that HarryN

Using the Xiaoxiang app I turned the charge and discharge function of the BMS off and on. This cleared the error in the Overkill solar app. I couldn't switch them off in the Overkill app prior to this.

I dont know what open and closed loops are. Id probably go with the simpler option and use a permanent voltage setpoint and current limit. Something that would draw enough amps from the generator up to around 80% SOC. If I forgot to switch off the generator the BMS should protect the bank. I'm...

Here it is.

I have the Vertive R48 3000e3.

Indeed I believe my output voltage isnt set high enough. It was set at 53.5v iirc, you can choose this when buying the unit. Id like it to be higher but I dont know how to program through the CAN bus. I can see where the 2 wires connect in but I'll have to look up the ins and outs of programing...

The output of the charger is probably limited to 50 amps. My generator wont be working at 80% probably less than 60% but its an old crank handle Lister/Peter so I'll go gently first to see how things develope.

I understand. I have wired the generator into the house now so I'm just about to crank the handle and start her up. Happy days. I have it wired straight to the battery but I'll send it through the BMS later for more fun! Yahoo! Thanks for all the info folks.

Brilliant, this makes sense regarding the sparking and connecting it up. The battery bank is only half charged. It's at 52.8v.

Ok this makes sense. I was connecting the charger to the battery permanently. I didn't expect to have to charge a capacitor like connecting an inverter. Can this sparking damage the charger?

I tested the wire from the charger to the battery with a clamp meter.
