That's what I'm saying, and it is true. I tested it this morning.
The 800watt Prowatt inverter, circa year 2000, has a small micro switch on one end, together with a green/red light. To use the inverter, I turn on the main battery
switch, then this small micro switch. I have an double side by side AC switch that can switch from Shorepower to Inverter, with a protective slide. After switching on the inverter via the small micro switch, the inverter's green light comes on, and a green light comes on beside the Inverter switch. I switch it on. Then I turn on the Outlets switch. A green light comes on beside the Outlets switch. Power is then available at any of my 4 outlets.
I am using a Galvanic box and GFIC outlets.
Everything is fine when the engine
is off. However, when the Inverter microswitch is on and when the engine
starts up, i.e. the alternator starts providing power, the light is RED on the inverter, there is NO power at outlets, NO green light beside Outlet switches, NO green light beside Inverter switch.
I did all the AC wiring
myself 15 years ago, but have not had much use for the Inverter as I had shorepower readily available, , now I don't, so the inverter is getting more use. i.e. this conflict might have been there since day one.
Why is this happening ?
