[APP][Pro] Elekeeper / SAJ eSolar Inverters

I created a separate thread for the modbus discussion not to pollute this thread:

[APP][Pro] SAJ - HS3 Modbus

I started to work on an app for connecting to your SAJ HS3 (and most likely H2) over Modbus TCP. It is still an early version but please feel free to test and play around. I will try to improve it quickly based on input.
