Improved compatibility with Solis RAI-3K-48ES-5G

[RadioactiveMan56]

Hi,

i have been testing the integration with my Solis RAI-3K-48ES-5G and the S2-WL-ST stick (Ethernet cable connection). On an old RPi.

The integration provides good data. Thanks!

This is a retrofit battery inverter (2 Pylontech are connected). No solar panels provided. The inverter has a CT connected that measures the current provided by a parallel solar panel inverter.

I suggest to add the following modbus registers to the hybrid data file (found those in the Solis document). I have confirmed these work in my configuration.

{
    "register_start": 33243,

    ]
},
