Application scenarios & economic value

Maximizing financial return and power resilience for your facilities

01 / Peak Shaving

Peak shaving & TOU arbitrage

Charge during off-peak hours and discharge during on-peak tariff hours to reduce monthly commercial power bills by up to 30% – 45%.

02 / Power Resilience

Zero-switch power backup (UPS)

Ultra-fast switching speed (< 10ms – 20ms) protects critical production lines and sensitive machinery against grid flickers and blackouts.

03 / Solar Self-Use

Solar self-consumption maximization

Store daytime surplus solar production and utilize it during high-demand or night hours, eliminating renewable curtailment.
