GRID-CONNECTED C&I MICROGRID OFF-GRID C&I MICROGRID ON/OFF-GRID C&I MICROGRID

Challenges

Unreliable grid and load-shedding cause costly downtime for businesses.

Volatile electricity prices and polluting diesel backups complicate cost control.

Solar generation often mismatches demand, resulting in low self-use and high waste.

Solutions

Functions

Supporting both AC/DC coupling, our multi-parallel PCS (up to 3MW) enables seamless grid-island transition (≤20ms) using PQ/VF control modes, ensuring uninterrupted critical load supply during grid failures.

The site EMS intelligently coordinates PV, storage, and generators to optimize energy dispatch, reducing diesel dependence while maintaining continuous power for critical operations.

Based on black start capability, achieving autonomous power restoration and system energy reconstruction.
