Neargrid
Boost
The quiet powerhouse in the Neargrid family provides renewable power for even the most demanding construction sites - enough to power up to three tower cranes continuously. Where the grid stops, Neargrid begins.

Always produce. Always Build.
A weak grid connection should never determine your progress. The Neargrid Boost keeps your construction site running-day and night, at every peak moment. The battery system acts as a smart microgrid that captures peak consumption and guarantees a stable voltage. So your tower cranes operate without interruption, even where the grid fails. No downtime, no loss of time : only continuity.
Your construction site produces without you having to think about it.
Maximum output
Microgridon your construction site.
The Neargrid Boost has enough with a three-phase mains connection of 16 A to power 1 tower crane.
Autonomy
Fully integrated electrical protection.
）.
In the event of a power failure on the grid, the Neargrid Boost as UPS provides power to the tower crane - uninterrupted - for another four hours.
Customized
Always informed, always current.
Our technology is fully aligned with the construction process. Neargrid focuses on the classic pain points construction sites face.
