When I had problems with my refg. inverter I called the Company WFCO. During the conversation I asked if I should turn off inverter when hooked up to shore power...he said not necessary. It goes into standby and then as soon as you disconnect from shore power it automatically turns itself back on. He said that way is best just in case you forget to manually turn it on when disconnecting from shore power. So that's what I do cause I know I would be the first one to forget to turn it on every time....been there, done that.
Also 2-6v batteries is best...AGM is even better but will cost more $.
