I have a multiplus 2, cerbo gx, and a seplos battery connected to cerbo. The ac output is not connected yet. So all power is used to charge the battery. So why does the graph says that 1% is for battery and 99% direct use? I have another brand mppt connected to the battery(48v)
Probably the system reached the target voltage for the final stage of the charging and consider it as charged.
It’s clearly seen that battery is idle and charging current is 0 from Multiplus point of view.
So, the energy is used for anything else, not charging/battery.
You say there us nothing on the output.
The system has not been told there is nothing on the output (is configurable in the GX)
The inverter is also an ac load. All power used was to run ac loads. System has used 0.15kw in the last 24 hours in the switched on and idel state.
