Has anyone ever installed a large (or otherwise smaller) power inverter on their boat. Considering putting an inverter on board to run the A/C unit when I'm offshore . Not an electrical expert by any means and am not even sure if this is doable. It would sure be nice to run the a/c on those smokin' hot days offshore. Also would be nice to run some other stuff too..... coffee maker , microwave, etc. The fridge runs off the dc side so it's not on the plan. I have twin 200 HPDI's and they have 45amp alternators each... Thanks Karl
