Neargrid
Compact
Small but powerful, that's the Neargrid Compact!
This smart battery system provides reliable, emission-free power on construction sites without a strong grid connection. Compact in size, big in performance: the Compact supplies quick-mount cranes, site installations and power tools with stable power: quietly, safely and without diesel consumption.
The Neargrid Compact is designed for construction sites with limited power capacity or no grid connection. The system delivers instant peak power when needed, supports dynamic charging based on current electricity prices, and works effortlessly with solar panels or a small generator. Compact is the ideal all-rounder: an autonomous, emission-free and cost-efficient power source that keeps small cranes, pumps, lighting, yard units and peripheral consumers running reliably, exactly when you need them. Power where there is none. Instantly deployable.
Smart power where there is little power
3-phase output from a limited or absent connection
The Compact delivers peak power for quick-mount cranes, pumps and peripheral consumers even when only 1-phase power is available. Thanks to integrated voltage regulation, power remains stable, with no interruptions or dips.
→ Always works, even in the most difficult locations.
Hybrid autonomy with minimal consumption costs
Less fuel, fewer running hours, less maintenance
Combined with a small generator, the Compact dramatically reduces fuel consumption. The system recharges when the group is active and then switches whisper quietly to battery power. Smart interplay between generator, battery and sun
→ Most economical solution for off-grid yards.
Plug-and-play for any construction site, immediately deployable
Quiet, user-friendly, robust
The Compact is ready for immediate use without specialized installation. Ideal for rapidly changing construction sites. The integrated intelligence ensures dynamic charging and optimal utilization of renewable energy.
→ Minimum effort, maximum flexibility.
