Due to irritating conditions with my grid provider, I can't touch my grid-linked inverters - they can't be moved behind my multiplus-II or the grid provider will terminate my feed-in contract and replace it with a very rubbish one..
So - my question..
I have two inverters (physically separate sets of panels) feeding the grid, I have rs485 metering on the solar feed to grid as well as the overall grid. I am happy and allowd to feed to grid from the inverters, but not the multiplus (else the above feed-in rate change), but want to prioritise battery charging and self-consumption.
What is the best way to do this? I plan to setup a Raspberry Pi with Venus OS and the Node-red image.
