This particular system is open loop at this time (which we set to try to diagnose the battery random shutdown issue) but the same thing was happening in closed loop (Pytes E-Box).
Am off-grid firmware is exactly what we need here. Customers "upgrading" from old Trace SW inverters or others are actually getting a downgrade in terms of autonomy. These new systems need babysitting.
