    only using 26 watts of lite, running a 25" TV ,a WEBTV unit,a dish
    network box,and a Playstation2 DVD/CD maybe 4-5 hours a day they will
    not all B runing at the same time ever (TV +WEBTV or TV+ Playstation or
    TV and the Dish) ........how much SOLAR would I need to have to keep
    batterys charged ?.......I have ideas of a 5 day power supply in the
    Battery bank....will I be able to do that? or will that many Batterys

    Make that FOUR 800 AH 6V batteries, if your estimate of 500 x 12v AH is
    right => That's 6 kWH. Divided by .40 (desired max discharge depth) =>
    15 kWH.

    2 x 800 x 6v AH is 9.6 kWH. So, you could get by with 3 such batteries,
    but 4 would give you 19.2 kWH capacity.
     
  3. Well thank you guys for the info.....I know I am prolly gonna get
    scolded fer' this but here goes can I use a Batt bank made up of 6
    115Ahr like Deepcycle batteries hooked together as one run out thru a
    2500 watt inverter and a 300 watt one ? charged everyday for a coupla'
    hours each day with a 60 amp charger from a Generator for a year or so?
    Its what I have axcess to now : )
