I tried searching for this online and on here, but can't seem to find anyone who has an explanation for what I am seeing. I have 9 panels, 100w each, in series for roughly 205v going in to my PowMr 5000 watt all in one inverter. At Dawn and Dusk, the charge controller is displaying 205volts on the PV (195-205ish) and then will connect, begin charging the batteries and the voltage of the PV array will drop as amps goes up. The voltage drops down to around 85 volts and then it disconnects the PV array and stops charging. Then seconds later, it repeats this whole thing. OVER AND OVER AND OVER AGAIN until the sun is fully up or until it's fully down and there is no light. Is this normal??? It's basically just cycling the charger over and over and over again. In the time-span of 1 minute, it probably does this 2-3 times.
