Off Grid Microgrid

Working Mode:

· Grid-connected operation: EMS executes preset energy dispatch strategies (self-consumption, peak shaving and valley filling, grid priority, etc.), optimizing electricity costs through coordinated photovoltaic and storage operation.

· Off-grid backup: In case of grid abnormality, the PCS automatically switches to off-grid voltage source mode within ≤10ms, ensuring uninterrupted power supply to critical loads.

· Energy Supplement: In off-grid mode, if the total output of photovoltaic and storage is insufficient and the battery SOC drops to the protection threshold, the EMS automatically starts the diesel generator for grid-connected energy supplementation; the system resumes pure renewable energy supply after the diesel generator is shut down.

· Automatic reconnection: After grid recovery and stabilization, the system smoothly reconnects through pre-synchronization control, ensuring a seamless transition with no impact or disturbance.

Applicable Scenarios:
Critical loads in data centers, factories, schools, hotels, shopping malls, and other facilities.

Advantages:
Integration of solar storage + diesel generator backup + emergency power supply to ensure the continuity, reliability, and cost-effectiveness of critical load power supply.
