Confirm that the reading matches the inverter's rated input voltage range (e., 220V, 380V, or 480V AC depending on the model). Always verify the incoming supply before moving. At its core, inverter DC overvoltage happens when the DC voltage feeding the inverter—or building up on the DC bus—exceeds the inverter's safe operating limit. Check if the DC bus is functioning correctly. Most modern multimeters are Digital Multimeters (DMMs), offering precise digital readouts, which are generally preferred over older analog models for their accuracy and ease. Error 2 - Battery voltage too high This error will auto-reset after the battery voltage has dropped. This error can be due to other charging equipment connected to the battery or a fault in the charge controller.
