I brought powmr POW-HVM-3.5H-24V invter in sri lanka.
But i install it using througt externel mppt 60AMP controller. So i use only battery mode in my inveter.
Could i knowIs it ok?

Sometimes onese a day inveter showing fault code 03 (high voltage from battery) but battery voltage is 28.5 or 28.7.
After inveter auto restart and fix it.
but Could i know why coming like this faul code.

I use this inveter everyday only till 10pm. After first i turn off load and turn off inveter. Next day i turn on it at 8am in morning. Could i know is it ok for invetet?

I have a question I recently purchased a powmr HVM 3.5 24v and I live in a tropical country where its overcast quiet often and rains sometimes for a week or so at a time so I've over panelled a lot I have 2 strings of 5 450w 42v panels is this to much for this inverter I've only connected 1 string thus far because I'm waiting for more clamps
Also I currently have a 230ah lifepo4 battery bank
