Question of ignorance from a newbie. I have a Victron MMPT 150/85 installed on my Motorhome. I have six 200-watt (1200 watts total) BougeRV 9BB solar panels on the roof to charge six-100 AH lithium batteries. Individually the panels will produce a measured 9.9 amps at 19.9 volts.(197 watts). They are connected as two sets of three panels in parallel (19 volts, 30 amps for each set). The two sets are connected in series to produce 38 volts, 30 amps going to the controller. The current is run to the controller through 10 gauge wire.
The batteries are already charged from shore power. In bright sunlight the controller shows 14.1 volts and 40 amps - 560 watts. Is this reading the voltage and amps going to the batteries from the controller, or the volts and amps coming to the controller from the solar panels? Put another way, does the controller reading depend on the state of charge of the batteries?
All feedback is appreciated.
