  2. Hello Julian,

    I am Abhishek from India, I have installed a 1kva solar power system at my house with battery bank of 24 v 200ah. I am having so much problem with charging the batteries with the charge controllers. when i connect the batteries directly to the solar panels without any charge controller the batteries get toped up in approximately 5 hrs. So can me help out to make my own charge controller like your or can you make me one. 24v 40amps. or you can just send me script and the parts list to make it my self.

    Thanks for all your videos ,
    Abhishek Sharma
