A member with a 2010 Itasca Sunstar suspected a failed Dimensions 300-watt inverter and asked which outlets it powers, whether it is essential, and whether planned rooftop solar would change that need. The immediate problem was a dead dinette outlet while connected to shore power, following an electrical burning smell and tripped breakers. Members described the inverter as supplying battery-derived AC power to selected outlets or entertainment equipment and passing shore power through to those circuits, rather than powering every outlet. They also clarified that this unit does not charge the batteries.
Resetting the inverter’s GFCI restored the dinette outlet, and switching it off stopped power there again. However, the member reported a flickering green light and a warming front panel, remained concerned, and pursued another member’s matching used inverter for $25 plus shipping. Members noted that outlet assignments vary between RVs and suggested checking incoming power, outlet connections, the GFCI, and downstream wiring or connected equipment before assuming the entire inverter had failed. Several noted that the GFCI itself can be replaced. No replacement or confirmed diagnosis was reported, and the question about solar remained unanswered.
