Briggs & Stratton PowerProtect 22kW Standby Generator with Symphony II Controller OVERLOAD Error Fix: Overload — Electrical Load Exceeds Capacity

Error code OVERLOAD on the Briggs & Stratton PowerProtect 22kW Standby Generator with Symphony II Controller means: Overload — Electrical Load Exceeds Capacity. The connected electrical load exceeds the generator's rated output capacity. The controller may shed loads, reduce output, or shut down depending on the overload severity and duration. Review which circuits are connected through the automatic transfer switch (ATS). High-draw appliances like electric ranges, central AC, electric dryers, and heat pumps can overload a residential standby generator. B&S PowerProtect models with the Symphony II controller support load management — verify it is configured correctly for your home's circuits. Reduce concurrent large loads. If the overload occurs during startup of a motor load (AC compressor, well pump), the momentary surge may be too high — consider adding a soft-start kit.
