The main code used for the solar system comes from two devices
SolaX Inveters
The invertors are queried using REST and return a JSON package POSTMAN has been pre-configured to do the same queries

Iammeter
This three phase device has its own native integration into Home Assistant
- Phase A = Power from/to the grid +ive is from the grid and -ive is power sent to the grid
- Phase B = The house meter board, so all power consumption except the SolaX's them selves and the EV Charger
- Phase C = Solar generation. Should be the same as sensor.pv_now from the calculation above
