I recently installed a 110/20 smart solar controller on to a system with two 125W panels feeding two firefly house batteries. I'm learning to interpret the information on the monitoring app. In the pic below the circle graph shows 0Watts of Solar at that point in time however the voltage is 20.18V. My question is does the graph represent the available power at the panels or the power that is being used (needs to be used) at that point in time. To clarify, the batteries are fully charged and the boat is connected to shore power.
