Customer Pain Points

Poor supply reliability exposes C&I users to grid faults and load shedding that interrupt production and cause heavy losses.

Daily price swings make traditional modes hard to control, while diesel backup is costly, high-carbon and noisy.

Renewables (e.g. distributed PV) suffer output volatility and load mismatch, causing low self-consumption and high curtailment.

Solution

Key Functions

Supports DC and AC coupling, PCS multi-unit paralleling (up to 3MW) and PQ/VF modes, with automatic on/off-grid switching (≤20ms) for seamless, uninterrupted critical-load supply.

EMS intelligently coordinates PV, storage and diesel, dynamically optimizing control strategy for stable multi-energy supply while cutting diesel use and securing critical loads.

Black-start capability for autonomous power restoration and energy rebuilding.

Customer Value

Optimized PV-storage-diesel control lets storage work with diesel against grid faults and load shedding, greatly improving supply continuity and stability.

Peak-valley arbitrage cuts daily electricity cost by 6%-12%; storage-diesel coordination lowers backup cost.

Storage regulates renewable volatility and load changes to raise self-consumption and reduce curtailment.
