    3000watt system is this set up enough ?

    Hi all,

    ive worked it out that i would be using around 2,800 - 3000 watts per day that is running my:

    2 pond pumps
    lighting for inside and outside
    use of dvd player

    my understanding of solar panels is that 400w would give me 400w per hour under optimum conditions, so i would say in uk weather i would get 150 during day time for 5 hours a day at most

    my system im thinking of using is

    200 w solar panels (will expand over time to 800-1000w)
    1000w inverter
    Steca 30A Solar Charge Controller
    battery bank (not sure)

    looking at 1 x 220ah battery (to start with) if i have a 24 v solar panel i would do a 24v battery bank even if i have to buy 2 x 100ah and then link them

    if this good or crap set up ?

    Thanks

    Ok I think you meant you will use 3 to 4000 watt hours or 4 Kwh per day. Watts is a measure of power not energy.

    If you are intending to use a battery system you have to use winter insolation or the winter shortest days, so you get no where near 5 hour seven in summer. Winter is 1.8 hours.

    So to generate 3000 or 3 Kwh of usable energy on a battery system you would need a 2500 watt solar panel.

    At this huge of a power level you will have to operate at 48 volts, so you would need a 60 amp charge controller.

    For a battery bank you will need a 48 volt @ 475 Amp Hours or about 1700 pounds worth of batteries.

    So to answer your question you are not even close to what you want.

          thanks for the info, "Psi feels like giving up on the idea of solar energy lol" i may just try to light up my lights instead as i cant afford alot atm
