I hope me and my feeble electrical knowledge can explain this, but I am baffled.
I have 200 watt solar panel on the roof of my new FWC Hawk Shell. I have the standard 12V 79 Amp Hrs AGM battery.
Victron Smart Solar 100/20 controller, wired by cutting the FWC wires, wiring the ones marked solar to controller into the controller PV and the ones marked controller batt into the Battery ports on the controller.
With a volt meter at the controller I get 17.2 - 17.5 V at the controller from the panel, and 13.5 V on the batt side. This coincides with what the Victron connect shows.
But my volt meter and my BVM only shows 12.47 V. Putting a voltmeter on the batt only show’s 12. 4+- at the terminals.
The end result is my battery never gets fully charged 88-89% but the controller thinks it is. I can drive and it gets to 100%.
Any idea where or how I could be loosing that much juice from the controller to the battery?
