New Energy Sources WhatsApp2. Battery Drain Condition. When an appliance is turned on, a considerable voltage drop results in a large current drain from the battery, which sets off the inverter''s low battery termination condition. Tracking the minimum battery voltage can help verify whether a battery drain condition is indeed triggered.
