Growatt AC PV inverter integration to GX

Q&A and troubleshooting DESS

Hello all,

I’m wondering if AC PV Inverter from Growatt can be directly connected to Cerbo GX.
(I know the Energymeter integration)

In the old Community there was a User (urs4-2008) who seams to have done that, but the datas did not work out form him. He never got a answer to his question.

Unfortunately the Forum is inactive, so no chance to contact him.

Thanks for your ideas

I currently use tasmota with modbus bridge for this. The modbus values are requested via mqtt in Nodered and fed in to virtual pv devices.

If you feel like introducing more systems into the mix, what I do with my huawei inverter is to poll it via modbus with a self-written script that then publishes the data to an external MQTT broker, and dbus-mqtt-pv is running on the GX device and subscribes to those MQTT topics and voila, the data is in the victron system.
