This system is in an RV (caravan). Victron Energy equipment includes SmartSolar MPPT 100/50, MPPT Control, BMV-712, VictronConnect App. Batteries at 100% SOC, 1.81A load, 600W solar array. It seems the controller has difficulty providing only the 1.8 amps drawn by the load steady state when the batteries are floated and not drawing any current. In this case, the solar controller stops supplying current, the battery drives the load, and then the solar controller pulses a bunch of current back into the battery to replace the charge used. Then stops, letting the battery continue to drive the load. This happens every few seconds. Charge current is steady when batteries are less than 100%. Here is a link to a video showing this MPPT 100/50 behavior
