Hello,
I have a Renogy Rover 20A MPPT charge controller. I had one Renogy 100 ah pure gel battery connected to it initially and tried to add a second combined together in parallel to get 12v 200ah supply. When I added the second battery, my controller started flashing error code one on display, with the solar panel also flashing. Now the screen only shows a 24v system when mine is a 12v system and error code one, which means over-discharge. Thing is both my batteries are around 86%, so they are not below the required voltage. Please help me with any suggestions.

Unhook everything and start over carefully............. |

Ditto that carefully ... wear gloves and eye protection if you are new at this. Make sure to read the Renogy info on how to connect batteries in parallel.

Please help me with any suggestions. Please contact techsupport for a walk through. Seems as though you have your batteries wired in 24V. Use a multi-meter to get the DC reading before plugging into the controller to be completely sure. |
