Architecture: PV + BESS + PCS (grid-forming) + EMS + VFD + LT panel + loads
Control strategy: Downstream-first motor sequencing with VFD soft starts; EMS coordinates PCS limits, state-of-charge reserve and grid import
Process flow: Truck → Primary crusher → Transfer conveyor → Secondary crushers → Vibrating screen → Product conveyors
No savings or performance figures are shown. Outcomes are published only from measured operating data.
A direct-on-line start draws a surge of several times running current until the motor is up to speed; star-delta lowers it with a second step at changeover; a soft starter limits it by ramping voltage; a VFD ramps frequency so current stays close to running current. Shapes are typical, not a measurement of any motor.
