Got an E2 error in the middle of the night. Code means low voltage to both sides of the house. Park electrical checks ok. Watchdog power protector shows positive flow, but drawing 11 AMPS with only a light running and the microwave connected, which is far from 11 AMPs. House batteries are brand new.
 
Is the E2 error on your thermostat?
 
Did you check the AC breakers?
 
Watchdog E2 error is either low or high voltage.

An autoformer will solve that issue if it’s low voltage.
