Hello all.
I want to measure all the cell voltages in my battery bank (voltage drops to 43 with 2kW load at 90% charge). I'm wondering if switching off the quattro open-circuits the battery bank. Basically, I'm hoping to avoid having to disconnect stuff.
Afraid not, there's a large bank of caps in the inverter which will still be connected. You should have fuses in-between, convention would have these pulled to properly isolate the battery.
Slight thread swerve. I've checked the voltages and all but one cell are at 2.23V which is correct. One cell shows 2.16V. Does anyone know if that could be contributing to my problem? I can never let the batteries go below 80% and even at 80-90% a load of 2/3kW will set the alarms going. A 4kW load will pull the voltage down to 37 and the system shuts down.
