SOLAR_EV_DIVERT
Solar self-consumption — diverts the PV surplus to EV charging without the diversion chasing its own load.
When to use it
Use SOLAR_EV_DIVERT when a site has on-site PV and wants the vehicles charged from the surplus that would otherwise be exported, with the operator able to choose between strict solar-only, solar plus a small grid top-up, and unrestricted charging.
