SORTED: The wiring configuration on the Pylontech CAN cable supplied was incorrect. A standard RJ45 cable will not work so check the pin configuration for the Pylontech battery and Imeon IMA-box. (GND) Pin 2 (Battery) connects to Pin 8 (IMA-Box) (CAN_H) Pin 4 (Battery) connects to Pin 1 (IMA-Box) (CAN_L) Pin 5 (Battery) connects to Pin 2 (IMA-Box). If necessary make your own cable it may be easier as only three connections are required.

I have an Imeon 3.6 inverter which I am upgrading to work with Pylontech US3000 lithium batteries. Imeon sent me the firmware/software updates for both the inverter and IMA-Box which I have just purchased. The firmware updates (DSP:17-04-26:17,30 and MCU:17-04-26,17:30) for the inverter and OS One update (v1.7.8.2) for the IMA-Box installed with no problems. I then connected the batteries (two in parallel with the link connection) to the IMA-Box using the CAN sockets. All Dip switches on the batteries are down (off). When I selected the PylontechUS3000 battery in the OS One software it was unable to connect and just keeps searching. Since the upgrade, the inverter will not charge the batteries either from the grid or PV panels but will discharge if there is no power input from the grid or PV panels. Also the inverter keeps randomly disconnecting from the grid when there is no power outage. I have checked all the connecting cables, reinstalled the software three times but still not working. Any suggestions please.
