    Is it possible to have an off grid system that takes the ac directly from the inverter for use and also powers the charge controller to the batteries? This way you are only drawing off the batteries as needed ( mostly at night ). It seems most diagrams show all the ac coming off the battery bank at all times

    1. In your suggested scheme, there are two power converters in the path from Solar panels to the batteries, whereas in the other model that you mentioned, one power converter, i.e. the charge controller is only one in the path between the solar panels and battery. The losses in the second power converter is avoided in the system. When you need AC, you need to make it, and inverter is needed here. Electricity from solar panels is conditioned by charge controller directly and sent to batteries.

    Mr. Almas,
    i have researched this problem and the basic answer is Yes, but…

    You must have enough solar cells to charge the battery bank in one or two days of good sunlight and ,

    a second inverter designed to take the 12 volt + DC voltage directly from the charger/controller and convert it to 120 AC with a power drop detector that will swiitch-back to batteries when the solar alone will not support you load draw.

    I am doing it manually and it is possible that way but a real pain in the butt to manage.

  7. i am using 1500w a day i wanna back up durring the night 12 hourto use these watts how many batteries i need

      you need 2 deep flooded cycle 12V – 120 Ah batteries for PV systems, connected in series..

      1. I am not sure why you said 2pcs of 120ah12V battries in series. He needs batteres to supply the 1500w loads for 12hours at night. Basically that is 1500w * 12 = 18000wh. dividing by 50% depth of discharge as you choose flooded, that is 18000/0.5=36000wh or divde by 0.8 if for AGM batteries, that is 18000/0.8 = 22500wh.

        to know the AH required, and according to the 24V you suggested, that is 36000wh/24v = 1500ah24v batterybank. or 22500/24v = 973ah24V battery bank.

        as for my suggested, 48V is better, and this will result in 36000/48v = 750ah48v = 4 batteries of 200ah12v connected in series

        or f use AGM, the result is 22500/48 = 469ah48v battery bank. = 4 batteries of 120ah12v batteres in series.

        this is without taking the battery temp losses factor into account.

  9. Any one giving idea what will happen if wire is connected in only one part of solar pannel instead of connecting in 2part??

  10. Totally WRONG!
    Batteries should NEVER be connected parallel!
    1) the lesser charged will drain the better one. Regardless if it is connected to the charger.
    2) they BOTH will be charged to the level of the lesser one.
    3) Depending on the circumstances, it can cause a fire!

    Parallel connecting can be done for a short period like jump starting a car. (Or a Space Shuttle, as we have seen it in Flying High … :) )
    Nothing else, really.

    They can be connected serial and charge with a 24 V charger. Still problematic if one battery is much worse than the other.
    The best is to have two 12V charge controllers. Both batteries will be charged to their ability.
