Hi guys,
Just looking for a trouble shooting hint. I have 3 SMA inverters and 1 Fronius Inverter. Cerbo registers the Fronious Inverter and one of the SMA inverters but does not pick up other two SMA videos.
Neither are listed in TCP Modbus Services or in settings/pv inverters
Both SMAs that are not being registered on the Cerbo are on the correct LAN (same LAN as working pv inverters and they all have IP addresses on the router). They do not get picked up in the "Find PV Invertors" Scan in the victron console and manually editing their IP addresses into the Victron has not made any difference.
I tried connecting to a PV inverter that cerbo does register through pymodbus but I kept getting a GatewayPathUnavailable Connection
shed_sma_client = ModbusClient('192.168.86.37', port='502', auto_open=True, auto_close=True, unit_id=20)
result = shed_sma_client.read_holding_registers(1039)
print("shed_sma_1_serial: %s", result)
>
house_fronious_1_serial: %s Exception Response(131, 3, GatewayPathUnavailable)
I am not sure if this is the the correct way to connect (192.168.86.37 is the IP address of the cerbogx and unit_id of 20 is the fronious inverter in the modbus device list. This is likely a red herring though as I am unable to get unit ids for the two SMAs that are not being automatically registered.
Both SMA inverters that I can't see in victron can be pinged from command line
Any ideas what could be happening here?
