Hi guys. Hope I'm at the right forum/site for my question and hope someone out there can help. I have a cabin in the woods with no power available. We use a generator at night for lights, ect. I want to set up a battery with inverter/charger to power a TV, satellite dish box, and one light bulb (60W) to use during the day without having to run the noisy generator. The TV consumes 120 Watts, sat. box 25W, and a 60-watt light bulb (intermittant light bulb use). I have selected this 750 watt inverter/charger http://www.tripplite.com/en/products/model.cfm?txtModelID=2938 and according to my calc's I should have about 5-6 hours continuous usage of all three appliances with a 200AH deep cycle battery. Hopefully a little more with the light off. My questions are: 1) do my calcs look right? 2) Will the charger in this inverter/charger be enough to charge the battery each night when the generator is running for approx. 8-hours,..or less? 3) Any suggestions on what battery to get or steer clear of? I would like to locate the battery indoors (warmer)-does this mean I need a sealed battery? I could locate battery outside and run wires thru the wall if I can use a cheaper more conventional deep cycly batt. (like wal mart ones). Cost is a major concern. Anyone see any issues or have any suggestions for what I am trying to do?
