+In general, if you can connect to your inverter with the official mobile app (SolarGo/PvMaster) over Wi-Fi (not
+bluetooth), this library should work.
 
 (If you can't communicate with the inverter despite your model is listed above, it is possible you have old ARM firmware

+Since v0.4.x the library also supports standard Modbus/TCP over port 502.
+This protocol is supported by the V2.0 version of LAN+WiFi communication dongle (model WLA0000-01-00P).
