It seems that charging status 6 is used for the full bypass mode.
This can be seen at cold temperature, when the battery cannot be charged.
In this mode, the solarbank seems to disable its MPPT tracking completely and only monitors the the work done by the inverter.
In this mode, the solarbank typically allows the inverter to run with <25-30 W, which is the required yield for the solarbank to start doing some work.
In normal mode, any solar power below 25-30W cannot be used since the solarbank BMS does not bypass it when NOT in mode 6 (=full_bypass) mode.
