I installed the
Xantrex PROwatt SW 600 which is about the same price as the Go Power GP-SW300. I also added their
inline transfer relay and wired it in so I just use the existing AC outlets in the camper. Idle current draw is a little higher than the Go Power (<0.6a vs 0.26a for the GP-SW300) but I shut down the inverter before going to sleep and during the day the solar (275W) will more than compensate. Powering the
Dish Tailgater and receiver is the primary reason I installed the inverter and since I discovered the Tailgater will occasionally do a satellite search and drain the batteries even with the receiver turned off I got the
remote panel which will let me shut it down and save the batteries from bed.
One tip, you are going to want to mount this as close to the batteries as possible due to the size wire you need and to minimize voltage dropped across the wire at operating current.
