[APP][PRO] Connect Solar Solax Inverter to Homey

Apps

Hello, I’m considering purchasing a Solax inverter and I have a question. Does the application work with local communication via Modbus with the X3-HYB-G4 inverter of the newer PRO series (power range 4-15 kW)?

Thank you in advance for your answer and have a nice day everyone.

Hello Zdenek,
X3 G3/G4 is supported.

Hello, I recently purchased a Solax X1-VAST-10K hybrid inverter and I’m unsure which mode to choose. I can see the inverter in Modbus mode, but it’s not suitable because it has four MPPT inputs and two battery inputs. Perhaps there’s an update available for your application. Thank you.

Hi guys and thank you Michal for an awesome app! Running a X3 Ultra 20K through modbus and working great. (Drops coms from time to time but I am running over WiFi for the time being so that’s probably the reason).

Just connected my second battery and I think that the data posts for SOH and Temp are switched around. When running only one battery all data was presented as battery #1 but now many of the variables are switched over. Don’t know how theese values are read and posted but perhaps the connecting/reporting order of the batteries causes this.

Do you have a Mesh WiFi system (e.g. Deco)? In that case, the inverter and/or the Homey can roam between nodes, which temporarily drops the connection. In many mesh systems, you can “lock” the inverter and Homey to the node that’s closest to the device. This prevents them from disconnecting to roam to another node.

Nah, running full Unify network, and yes, critical clients are locked to their AP’s. The dongle is known for stopping the Modbus server from time to time on WiFi. Does not respond to ping on 502 when it breaks either.

Hello,

Just configured an Elfin w11 and put a network cable in S485 port on my Solax X1 boost Air mini.

On my elfin I used blue and blue/white wire to connect from RS485. I already installed the elfin, static IP and it online on my 2.4g network.

Hoever, when I try to add a “modbus G3 device” through this app, it says device not available after I added it.

Any solutions?

I mamaged to setup Cloud Connection before and itnworks for reading Solax values, but I want to use Modbus now to also be able to change Solax settings ( foto example limit inverter exportation when Energy price is negative)
