Hello Everyone,
Great Forum I have already learned a lot. Forgive me if this has already been answered but I couldn't see it
For my first setup, I have assembled a 40V 300W solar array attached to 200Ah sealed lead-acid batteries (2x 12v 100Ah in parallel) through an epsolarpv 30A MPPT.
Before hooking up the solar a quick test with a multimeter shows 39V good for a cloudy day. As soon as I connect it to the MPPT charger the display reading (and a test at the terminals) begins to drop to approximately 13V.
Is this the MPPT dropping the voltage to increase the AMPS to charge my battery or has the charger or I doing something we shouldn't?
Thank you for your help.
