EG4 › AC output / EPS inverter stage
Inverter throws EPS overload warning under light load
reported in the field
Symptoms
- Charging from solar with the BMS throttling current near a full battery, a 6000XP repeatedly throws an EPS Overload Warning and drops to Grid Bypass even for loads as small as 200-300W, clearing the instant the solar disconnect is opened
- A paralleled pair of 6000XPs throws EPS overload above 50A/12kW on grid power because the Discharge Current setting defaults to a single inverter's 140A limit instead of 280A for the pair
- And a water-pump startup surge sends a 6500EX-48 into a cascade of flashing error codes and a full shutdown
