2) Update toc.rst to include powmr.rst example file, whilst also alphabetically sorting inverter examples by name (but SunSynk first)
3) Upated Victron example to refer to the Victron GX integration being used, as page appears to have been copied from FoxESS example and forgotten to update the integration being used.
