1. Disconnect the large 12 volt positive cable to the Inverter for 10 minutes and then reconnect to reset a Inverter. DO NOT have the 120 shore power or Genset ON when you do this.
2. The 50 amp or 30 amp setting only has to do with how MUCH 12 volt amps are used when charging the batteries. The default is always 30 amp when power has been disconnected. The difference between 30 and 50 is about 1 hour difference in bulk charging so just let the 30 amp stay. On 50 amp the bulk charge rate will draw about 12 to 13 amps AC amperage. On 30, the amp draw is about 9 to 11 amps. This is ONLY while the system is in BULK charge and it will go off bulk charge quickly (less than 1 hour) if the batteries are at least 75% fully charged.
