I'm planning my off-grid system. The main issue I have is the AC coupled wind inverter which doesn't support frequency shifting.
In order to protect the batteries from overcharging my plan is to use Morningstar Tristar PWM in diversion mode.
Unfortunately it doesn't support communication with BYD's BMU. I hope it's possible to use Modbus communication and send to it charging parameters from the Venus OS (node-red).
It will allow TriStar to dynamically divert excess power and keep the batteries happy ;)
Do you think it's possible?
Thanks for your help ;)
