Cloud Connected

Proprietary BMS and EMS with real-time monitoring, predictive maintenance, and remote control.

ENERGY MANAGEMENT SYSTEM

Software built around our cells.

Our EMS is developed around the cells we produce. Every parameter, every control loop, every predictive model is calibrated to our own cell data. The result is a system that knows exactly what it is managing, because we built both.
