Hello everyone.
Before 2 months i installed a solar system Energy Center with below detail:
1- 180KVA Quattro-II
2- 126 kWp Solar panels/ 122kW Fronius
3- 14,6 kWp Solar panels/ 100-450 VECC & 200-450VECC
4- Pylontech Batteries US5000 x 26=130kWhr
5- vm-3p75ct x 12pcs
now i want to know if i can integrate a Huawei ongrid system 650KW with Victron VRM.
Huawei inverter Models: Sun2000-115KTL-M2 & Sun2000-150K-MG0
The connection of Huawei inverters with my Energy Center will be according to attached SLD.(red rectangle)
RAK-Farm project SLD 26-05-2025.pdf (559.5 KB)
Additionally we will have a Hydrogen Generator 100KVA in the future. (red rectangle)
I have a huawei inverter (albeit a little bit smaller 
) where I poll the dongle via modbus/tcp and publish that data to MQTT, and then that is read by dbus-mqtt-pv on the GX and I can see it as AC-coupled PV there and in VRM… If you can read and modify perl code, I’d be happy to make it available.
Thank you @cmock for your reply.
First of all, please note my system already have Fronius PV inverters 126kW and i would like to integrate a Huawei PV inverters 650kW, so in this case we will have two deferent PV inverters.
Second, from my knowledge Energy Management System (EMS) have a limitation in the capacity of the system, e.g (some EMS can manage upto 250kW of solar systems and 150kW of generator), so if the GX have a limitation a want to know.
Third, if Huawei can integrate i will use Energy meters on grid and Hydrogen Generator side to limit the feed back to zero.
