Hi Pat,

If it were up to me, I'd always put a properly sized breaker on the distribution side of the circuit to protect the wiring (i.e. the fire hazard). A GFI outlet will work, but is primarily intended to trip anytime it senses the presence of a path to ground to prevent shock to a person. Usually, they are only used where there's a reasonable chance a person could provide that path, such as through the copper plumbing of a bathroom or kitchen. In other words, you wouldn't wire an entire house with GFI outlets to eliminate the need for breakers on the main breaker panel, but you could use a GFI breaker in the panel to feed all the outlets for added personal hazard protection.

How do you have your inverter wired to the 110 VAC receptacles? For example, Amel wires the 220 VAC receptacles from the inverter through the breaker on the 220VAC panel.
