I am considering purchasing the Giandel 4000W 24 Volt Heavy Duty Pure Sine Wave inverter. The only AC outputs I see are four 120V outlets. I want to connect it to a Reliance Control transfer switch. Assuming that is possible, how would I make the connection??? Would I use one of the AC outlets? I don't see any output lugs. BTW I have no 240V appliances that I need to power.
