| + | >> 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:// | ||
