Generac home standby generator code 2100 to 2103: meaning and exact next steps
2100 to 2103 means Overload, remove load. The generator is being overloaded by excessive electrical load demand, meaning the load exceeds its rated power capacity. The LED is red and the Mobile Link message says an overload alarm occurred. This answer applies only to Generac air-cooled home standby generators (and where a row says so, liquid-cooled) that show these codes on the controller or in Mobile Link. Generac says an article for a code with the same first two digits generally applies to its variants, and that Evolution controllers show the code on an LCD while Power Zone 200 controllers show it only in Mobile Link.

Generac's steps: disconnect or deactivate non-essential loads by unplugging them or turning off breakers in the main electrical panel, and make sure the remaining loads running together are below the generator's rated capacity. If you use a Generac Load Manager, verify it works and its lockouts are configured. Then, with the generator's main line circuit breaker and the utility main line breaker OFF, clear the alarm: on Guardian series press OFF then ENTER, and on Next Generation series hold OFF for at least three seconds.
