Easy Integration with Onsite Solar

The full dispatchability of Mainspring products allows them to easily integrate with onsite solar and energy storage, while following and matching power output with building demand. Linear Generators ramp up when solar is not available and ramp down to optimize use of the renewables when they’re actively producing. In many cases, a large rooftop solar array, tracked and firmed by Mainspring products, can cover the entire power needs of a facility. Excess solar produced can be exported to the grid.

Resilient Power Ensures Business Continuity

Operate flexibly with and without grid power
Grid On

Grid parallel operation in prime, demand-following, and peak shaving modes with the same project. Run any mode, anytime.

Capable of accepting full load from grid-parallel or standby in 10 seconds

Grid Off

Grid-forming/islanded operation provides power when the grid is down and can seamlessly transfer back to grid-parallel.
