I have a MultiPlus II GX 48/3000/35 with a Pylontech US3000C installed with the latest firmware. Configured including an ESS.
However, the ESS relay test is listed as pending in the Remote Console and therefore blocking the inverter to work. With a system reset the test is shortly listed as completed, but once the ESS starts the test changed to pending again.
The battery is loaded to 100% and is toggling between bulk and absorption state only.
I have reconfigured everything multiple times and also flashed the firmware twice.
Any proposals?
