      what is the minimum PV input voltage? IE: I have a single panel, that produces between 8 and 18 V depending on sun intensity , and angle. Wondering if at the low end, the controller can raise the voltage so it'll still charge?

      Answer This Question

      The charge controller is going to need to have at least 16 volts incoming otherwise it will not power on. You are going to need to have to at least two of those panels in series to ensure that the voltage is constant. Keep in mind that this particular controller has a maximum wattage intake of 260 watts.
