Non Marine Inverter
DipBouy,I belong to Costco, but they don't carry 6 volt batteries. I had read postings about the good buys for 6V batteries at Sams Club. I got a one day pass and bought a couple.When I did my electrical rewiring, I went the marine route, except for the inverter. I figured that at $89 dollars, I couldn't go wrong. Anything else, at 1500 watts was $250+. And if you want a true sine wave inverter, it is many times that price. When it fails in the marine invironment, I will buy another (or maybe a marine version if the price is right). To test the inverter, I ran my 1500 watt west marine electrical heater on the inverter (sucks about 125 amps out of the batteries!) I only wanted to be able to run the microwave while at anchor. I tried to run the hot water heater, but it is just at the ragged edge of pulling the battery voltage down enough to cause the inverter to alarm (whistle). Works great for the microwave!I bought the relay at an electronics place for about $20. It was a 120VAC coil, DPDT, rated at 30A.hope this helps,Michael
