Have a client with a BYD / Victron set up. Has a 150/70 controller for solar. 250/60 controller for hydro. The 250/60 is set up with using relay to divert load when BYD doesn't need anymore power. Diversion is done by a 230V relay from the power system to electric underfloor heating.
Problem: When diversion is active and it's sunny the system clips the 250/60 and uses the 150/70 to power the diverted load which I need to keep the 250/60 with load to stop over spin of the hydro.
Question: How do you prioritise one MPPT over another MPPT when EXT controlled by BYD/GX?
