I have a 24V setup with a RCT Axpert 3kv inverter, I have recently attached solar leads to test a panel array.

After removing the solar array and wires ime still getting a 10W charge reading from "solar" and also reading a pv_input_voltage of 19.5 v

Has anyone seen this before, how can i resolve this?

My guess is it's rounding/measurement errors for the power, and the voltage is battery voltage less several volts through various components.

As long as you get sensible readings when the panels are active, I would not worry about this.
