Generator/Inverter question

Your year RV and model, show that you have an Inverter/CHARGER, not just a plain Inverter. Your model, when 120 power is supplied(Shore or Genset) the Inv/Charger AUTOMATICALLY charges the coach battery bank. IF you have the Inverter ON, the Inverter goes into standby mode(NOT inverting) while you have the Genset or Shore Power connected. On your Inverter remote wall panel. You can turn the Inverter section On and OFF. The charger is automatic, but you CAN turn the charger off, but there is no reason to do that. The fact you have the overtemp fault light means that the Charger section is not functioning as long as the Overtemp is ON. It is BEST to leave the Inverter side OFF all the time unless you want the Inverter to supply 120 power when no Genset or Shore power. The reason is-- if you forget you have the Inverter ON, then when you disconnect 120 power the Inverter will drain your coach batteries in 3 to 4 days. The 50/30/20/15/5 Shore power should be set to 15 or 20. This reduces the amount of 120 amp draw the charger will pull in bulk charge mode. Real helpful if NOT on 50 amp shore power. The difference between 50 shore and 20 shore setting is just about 1 to 2 hours more(20 setting) to fully recharge the coach batteries. To reset the Overtemp, you turn off all 120 power, disconnect the 12 volt positive cable at the Inverter for 10 minutes, reconnect and then supply 120 power(Shore or genset), If the overtemp light returns you need to get it in for diagnosis.
