I have an 80W Gioco GSP polycrystalline solar panel and a Epever Tracer 1210A controller connected to a 320 (2 x 180) Ah AGM battery system on my sailing boat.
I have tested the solar panel with a multimeter and when disconnected from the charger I got readings of 12V and approximately 6A which seems as expected.
I have connected the batteries to the controller, adjusted to battery type to GEL and then connected the solar panel.
The controller shows that the solar panel is connected but it never shows it putting charge into the batteries. My battery voltage has always been over 12V and therefore higher than the solar output voltage.
In addition to the solar panel, I also have the engine alternator, a 240V battery charger system, a low power inverter and a NASA BM2 battery monitor with 200A shunt. All devices are connected to the shunt and only the shunt is connected directly to the battery negative.
My tests were carried out without the engine running and with the shorepower (240V) disconnected, although the batteries were always above 12V.
I would appreciate any assistance in resolving this.
The controller is designated as positive earth and the boat is negative earth however I wasadvised that this was not an issue when I purchased the system.
