  1. Powerforum Store's post in Deye Inverter with (older) BYD Battery-Box Pro 2.5 battery was marked as the answer   
    Hi @demaniak
    With 3× older BYD 2.5 modules 7.7 kWh at 0.5C, you’re limited to roughly 3.8 kW continuous charge/discharge.
    The 12kW Deye is too big for this bank it pulls hard on grid failure and trips the BMS.
    Recommended settings:
    Set battery to Voltage mode (not SOC)
    Max charge current: 70–75A
    Max discharge current: 70–75A
    Discharge stop: ~48–49V
    Charge end: ~54–55V
    This should stop the shutdowns.
    Long term you’ll need more storage capacity for a 12kW inverter that can charge and discharge at 240A 12.3 KW
