But with less load why does it need the same watts?
How about this angle. It is not the inverter that is causing the spike, it is the solar charging current. While the inverter is under the small load, the solar is contributing some of the DC for that load. When that load is removed, the solar is still contributing. Since the solar current no longer flows through the batteries to the inverter, it stays in the batteries. The voltage on the batteries begins to rise and since I'm at the bulk setpoint the voltage rise exceeds the setpoint level. The controller notices this a moment later and clamps it back down.
