I know you need enough battery bank to run an inverter, so Im trying to figure out exactly the setup I want.......Right now I have the 2 stock 12v coach batteries. I want enough inverter to run the TV/DVD, and Hopefully the Microwave, and be able to use outlets for fans, phone charger, coffee maker, etc..............(If I wanted to Tow a battery trailer Id love to be able to run an A/C off an inverter
) Ive read that mid range inverters may leave HD tv's with some distortion, so right now Im leaning toward a Sine Wave.........Ive thought about a Prosine 2.0, because I could get an upgraded charger for the batteries with it. That may be more inverter than I need, though..........So, If I were to add two 6 Volt Batteries, would that give me enough power to boondock for a few days, and run a fan, etc......or should I look at addid 4 batteries?????
