BEYOND THE GRID.
For remote locations, critical infrastructure, or sites where grid reliability is simply not good enough — BESS provides autonomous, dispatchable power without diesel dependency.
Volthein designs and integrates off-grid and hybrid BESS systems — combining battery storage with solar, wind, CHP or diesel gensets into a unified microgrid. The Volthein EMS acts as the central balancing controller, ensuring continuous power supply with minimal fuel consumption and maximum renewable utilization.

<20ms
Switchover Time
Seamless transition to battery backup in under 20 milliseconds — critical loads remain powered without any interruption.
70%
Diesel Reduction
Typical reduction in diesel generator runtime when BESS is integrated with on-site renewables in a hybrid configuration.
