Operating Modes

Four Ways to Power Your Site

EVOX adapts to your infrastructure. Choose the mode that fits your project.

01

Grid Mode

Charge from the grid during off-peak hours. Discharge during peak demand. Maximize Time-of-Use savings.

Grid → BESS → Load
02

Genset Mode

Pair with existing generators to eliminate idle fuel burn. Generator charges BESS, then shuts off.

Genset → BESS → Load
03

Hybrid Mode

Seamlessly combine grid and genset power. Intelligent load balancing ensures uninterrupted supply.

Grid + Genset → BESS → Load
04

Solar + Hybrid

Full renewable microgrid. Solar panels charge BESS during the day, with genset backup for cloudy periods.

Solar + Grid → BESS → Load
