Hey there, i have a question about my setup. I have a Huawei SUN2000 10kW M0 inverter with battery input but these are still not available so want to build my own battery. I use PV panels 380W 40V 10A. My inverter supports max 11A per MPTT so i was able to connect panels only in series an create 2 high voltage strings, 600V and 350V. My idea is to build a lifepo4 battery pack which will be charged via AC-DC charger, and then in case i will need the power from battery use DC-AC inverter ( same as UPS does). My questions are:
1. what would be the ideal battery pack voltage for this purpose?
2. would i be able to charge battery via mppt controller ( high voltage) ?
3. would it be possible to use the solar inverter to feed the correct voltage to mppt input? In this case i wont need to buy additional DC-AC inverter.
thanx for all suggestions.
