Charger and Solar controller not meshing well?
I have a WFCO charger and Go Power charge controller. I can get model numbers later and also check my manual.
This morning with the charger and solar both connected, I had 2 amps of juice running backwards from the batteries to the controller. Using a clamp meter to measure i can tell the direction the power is flowing.
Here is the sequence.
1. Solar connected. Charger disconnect switch is Open. Trailer on shore power.
2. The solar display is showing 14.7v. Power is running from the solar controller to the batteries with enough amps to maintain 14.7v.
3. I close the disconnect which now means the charger and the solar are connected to the batteries.
4. Immediately I notice the solar display voltage drop to 13.5v. The WFCO charge wire is now giving amps to the battery. While the power on the solar charge wire is now going backwards. 2 amps are being pushed back from the battery to the solar controller.
5. I open the disconnect switch on the charger and voltage goes back to 14.7v with power going from solar to batteries.
