STANDBY
HOT READY
DC Link pre-charged at 768 Vdc (LiFePO4 EBC 20S rack). PWM gate pulses inhibited to eliminate switching losses. Sub-cycle fast-wake auto-ignition (<2.8 ms) upon grid sag event.
CHARGE
AC → DC
Rectifier operation: draws regulated power from AC bus / PV to charge LiFePO4 battery pack with programmable power, current limits, and zero-export buffer protection.
DISCHARGE
DC → AC
Inverter operation: injects power into facility bus for load peak-shaving (>45 kW), series sag boost assistance (<2.8 ms), or scheduled dispatch with deep-discharge protection.
