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.
Hello again
is there anyone have an idea about the above?? requesting for support
thanks in advance
Greetings to all,
I haven’t received a response yet. This matter is important, and I need to know whether it is possible to integrate a Huawei 650kW inverter with a Fronius 125kW inverter and a Victron Energy 180kVA system.
I hope to receive a response as soon as possible, as this is a live project and I don’t want to risk losing it.
Best regards,
Hello Guy,
Thank you for your support and for addressing my question during the recent virtual event.
As per the guidance provided by your team, we understand that the Huawei inverters should be connected to the same internet source as the Victron VRM system. Once connected, we can retrieve the IP address of the Huawei inverter and use it to integrate the system with Victron.
Kindly confirm if my understanding is correct. If so, we will proceed to document this as the approved solution.
Hi @Fadi
I am always reluctant to say something for sure will work until I have done it myself.
What I can say is that Victron puts up no barriers and makes it as easy as we can to support this kind of data. There are numerous different ways, from direct IP connection, to energy meters, to virtual MODBUS TCP devices, that I can say there will be a solution.
Hopefully an easy and straight forward “it just works” one, but if not, eventually “you made it work”.
