  2. Battery Backup time

    waqar85 posted a topic in Batteries
    Greetings! I have a sample question if anyone can help kindly reply. Let say my battery bank Wh is 7200wh (12x150Ahx2 +12x150Ahx2)(2 in series and 2 in parallel) Installed solar panels = 1650wts (3x275 + 3x275)(3 panels in series in each row and 2 rows in parallel) sun hours = 4 charge controller 50Amp(MPPT) so what will be my battery bank charging time? Is it simply dividing battery Wh/Panels wts? and if i want to decrease battery charging time than what i need to increase solar panels only?
