My inverter mecer 1200 12v (old type with external transformer)   went faulty. IWhen connected normally {12v battery and to mains 230v withhout switching inverter button on} the input voltage on display shows 470v ac and output volts 230v ac. also know effect when use 10/20 amp switch {switch fine, although there is charging current at 14.2v dc. If i remove mains inverter just keep on working not swiching off amd still showing 470v. When connecting batteries only  and switch inverter on the input ac volts on display show 470v {mains not even connected| output ac show 230v. Is this a software problem? What about a factory reset.?
