Hi,
I have a Multiplus II 48/5000 GX with Pylontech US5000 batteries and an ET112 meter.
I have tried in vain to connect to the inverter via the MK3-USB device.
HP Laptop operating on Windows 10
Cable Cat5e (approx 3m long). Also tried a Cat6 cable 6m long.
Can Cables to pylontech, Ethernet and ET112 remained in place.
I did have the MK3-USB connected in the Laptop port and the RJ45 connected in the free CAN port on the inverter when downloading the VEConfigure 3 software (I see on here some advice that this should only be connected after the download).
When selecting a communication port, it does give me a drop down 'Com 3 (USB Serial Port) and the device has a green indicator in my devices settings - am I to assume the drivers have loaded ok and the device is connected to my laptop?
I cannot however get beyond 'connect cable and switch on device'. Batteries are on and I switch the invertor to 1 (it then starts charging the batteries - which worries me as I have not checked settings).
After 10 or 15 seconds I get message pop up saying 'Help in Communication' and that's as far as I can get.
I can see the inverter on Victron Connect and the VRM portal along with my ET112. It has monitored power used when I switched the unit on). I managed to update the firmware via bluetooth using Victron Connect, but I cannot adjust any settings this way.
At present I have the unit switched off and I have run out of options.
HELP!
Andy
