I am in the midst of configuring a new lifepo4 battery bank in my off-grid home.
The battery bank will consist of three TechDirect pre-assembled BYD units with an installed BMS - approx 3kwh/105ah per unit. The BMS is rated at 130a continuous but I would derate that to 65 amps per unit based on the attached specs and general caution. The three units will be connected in parallel.
My inverter is the Schneider Conext SW4024 - rated at 3000kw continuous /7000w surge. According to Schneider it has a 16 mF capacitance (as if I knew what that means). So here's my question:
Do I need a pre-charge circuit for my initial inverter inverter hookup - or does the parallel connection of these three BYD/BMS units compensate for the potentially high inrush current?
