I have a question about inverters connected to the JK BMS. If the JK shuts down for over or under voltage what happens with the inverter. Will there be a current spike when it comes back on?
Overvoltage no, since it keeps discharge enabled, only charging is being disabled. This makes sense because you really want to keep discharge enabled on an overvoltage condition to bleed off the cells.
On low cell voltage, yes - but the inverter will also try to run from the solar charge controller once sun is available and it tries to charge the battery. Ideally you want to have a mechanism to either 1) keep the inverter off in this situation or 2) have an automatic pre-charge system in place with inverter on/off function. I'm not sure any of these solutions exist off the shelf...
