My husband has fried 2 power inverters by not installing them or wiring them correctly. The most recent one was using the wrong gauge wire. He is having his 3rd power inverter professionally installed this week...
Actually the manual that came with it recommends that you have it professionally installed. It's about 30 bucks to have it done, so worth it, I would say. Either way, the manual that came with our inverter says what gauge of wire to use...maybe it's listed in yours too?
And we have our Igloo inside the little cabinet next to the bunk right under the pull out desk, and it works just fine.
