I'm hoping someone can help with this mystery.
Background: I tested the voltage on an existing 3 Renogy 100W solar panel system. I also purchased a new Renogy 100W panel. I was not able to test the currents.
The Renogy Rover 40A controller is correctly set for 12V and Li. No errors are shown in the indicator lights or throwing an error code.
The combined voltage for all 3 solar panels was about 58V, as measure by the Renogy box. Each panel had a roughly 19V output.
The voltage for the new panel was 19V also.
With all 3 panels hooked up in the system, only the 2nd, from the top, of the 4 led indicators lit on the Renogy box.This indicates that there are no issues with the battery. However the battery does not charge.
Periodically the top led of the 4, that indicates “charging", would light for ~2 seconds and then go out. When lit, the voltage, as measure at the Renogy controller, would appear to drop steadily from around 58V to roughly 20V, then the top led light would go out, charging would stop, and the voltage would return to 58V.
I unhooked all 3 panels and re-hooked up only 1 single panel. The voltage listed on the controller was 19V. The same sequence would occur as with the 3 panels hooked-up.
I then hooked-up only the new out-of-the-box solar panel. The voltage listed on the controller was 19V. The same sequence would occur as with the 3 panels hooked-up and also the single older panel.
