    Yes, at that battery voltage, that order of magitude drop in pv voltage would be quite normal. Assuming you have panels in a series string of 3, that would be a panel open circuit voltage (Voc) of ~ …

  • Re: pv volts

    It may help if you could post the numbers (ie pv in voltage goes from what to what?), and what the battery voltage is. Assuming the voltage drop is not huge, it may just be the normal operation of th…

  • Re: Power fading in and out

    EstragonEstragon
    It certainly sounds like a search mode / power saver sort of pulse. Putting a known higher load like a 60w filament bulb on the circuit would confirm. As a side note, I once accidentally left my phon…

  • Re: Best way to charge 12v battery. 36v 12v MPPT

    EstragonEstragon
    The amps needed depends on the total capacity of the battery(s). For example, if you have 200ah (capacity at a 20hour discharge rate) flooded lead acid, you would want something like 40a charging cap…

  • Re: I need help! 12v over 24v

    EstragonEstragon
    It's generally a good idea to define & describe load needs first, then figure out the best way to meet those needs. It isn't clear (to me, at least) from the question that an inverter is needed a…
