| >> My epever often pulls pv voltages down to battery voltage acting like PWM. Getting really annoying now. It works okay with 12v and 17.5v panels, but the bigger panels with a voltage of 35v present a problem on cloudy days. It drags thr voltage down, and doesnt let it back up until i reset the unit. It then lets the panels back up to proper voltage and starts producing decent power again. ([[https:// | >> My epever often pulls pv voltages down to battery voltage acting like PWM.

| + | >> I have 3210AN and the same problem. I only have one panel Risen 440Wp Vmpp 43.8V. In the morning or in the cloudy sky Mppt does not work. Holds 14V about 24W. When disconnected it goes on about 43V and shows 100W. This is annoying. This is evident software error. -- [[https:// | ||

| + | >> im having the same issue with epever charge controller. Early morning before the sun fully hits the panels 17 volts and .5 amps from a 60 volt array 300 watt array. I can unplug the panels and reconnect at it goes up to 57 or so volts then slowly drifts back to 17 again. Does the tracking just not work right or what is your opinion. I ran 2 100 watt 18.9 vmp panels on the epever. And 2 on a pwm. The mppt would go from 150 watts in full sun to 100 watt output every 20 minutes or so. And the pwm would steady put out 148 watts. In an all day comparison pwm won producing more watt hours.((https:// | ||

| + | >> I threw out my EPSolar Tracers for the same reason, equal paneling with correct voltages in a test of 3 EP Solar Tracers verses 3 Trace C-40 PWM The old trace units preformed much better. ... [the epever] would slowly sink in PV input volts until reset or maybe 20-30 minutes later would do a full sweep and come up to a decent input voltage. I bought a Classic.....problems gone((https:// | ||
