So about a month ago I had my system setup and got to monitoring via mondbus/homeassistant all went well until 1 MPPT (150-45A) was faulty worked till ~1200-1300 then just stopped producing power until the next day (even when a load came on it never ramped up) was sent in a then replaced as faulty, now to soso pickle,
The Unit ID’s were 226 Cerbo GX VE.Direct port 1 VRM 279 and 223 Cerbo GX VE.Direct port 3 VRM 277
All was well until I got a temporary unit and its UNIT ID was 280 (also same on VRM [odd]) now the replacement is UNIT ID 281 on the GX and 281 on VRM and cannot get any data on modbus of this unit.
As the last resort I have moved EVERY thing away from modbus to MQTT, this is just very odd and still happy to use MQTT.
MQTT also says the id is 281 N/###/solarcharger/281/Yield/Power
