Is there some special requirement for the EPS load which is connect to inverter EPS port?

Ensure that the EPS (Off-grid) load rated power is within the EPS (Off-grid) rated output power range, otherwise, the inverter will report an "overload" warning. When “overload” occurs, adjust the load power to make sure it is within the EPS (Off-grid) rated output power range, and the inverter will automatically return to normal. For non-linear loads, ensure that the inrush current power is within the EPS (Off-grid) rated output power range. When the configuration current is less than the maximum DC input current, the capacity and voltage of lithium and lead acid will decrease linearly.

Note: The EPS load of the inverter does not support a half-wave load, and the half-wave load cannot be used here.
