Control SolarEdge Battery Charging

[Peter_Kawa]

As far as I know the Solaredge + Growatt app controls inverters and such using the “TCP Modbus” protocol, Peter.
See:

[APP][Pro] SolarEdge + Growatt TCP modbus

Purpose The difference of this app and the already existing solar panels app is that this app reads the data directly from the inverter. The solaredge api and others are mostly limited to 300 calls/ day, so you get only updates every 10-15 minutes. The modbus app receives data every few seconds. If you have the Solaredge energy monitor installed you can maximize your self-consumption and limit your exported power by using it. You can make flows based on your generated solar power, exported p…

If your inverter hasn’t got TCP Modbus built-in, you can consider adding a 3rd party Modbus-LAN interface.

So, took the plunge and ordered the Waveshare RS485 to PoE Ethernet Module and had some time today to hook it up and configure it. I connected both my Growatt 3000TL3-S inverters to the module and after some fiddling on the Inverters (Giving each a unique ID) and in the module’s settings I got it working! Here the settings that work for me: [image] I made the following changes that differ with de module’s default settings: Network Settings Device Port, set it to 502 IP Mode, switched it …
