AC Mobile Power Supply for Temporary Sites

Battery-powered AC supply for construction sites, renewable storage, and no-grid temporary locations.

Why Mobile Energy Storage

Powering the gap on construction sites.

Remote locations, unstable grid access and heavy machinery demand often lead to project delays and safety risks. Volttera's mobile ESS platform delivers clean, dependable power with modular, pre-engineered components — easy to transport and quick to deploy on any site or temporary facility.

No Grid Connection Solution

Power the site in island mode.

Supply the construction site with electricity from Volttera's mobile system running in island mode — recharge batteries overnight at the nearest grid connection point.

Highly Variable LoadsCost benefit at applications with varying demand
Zero EmissionsNo fuel burn on site
Lower Noise LevelsQuiet operation on sensitive sites
AC Mobile Power Supply deployed outdoors
AC Power

Built For Temporary Sites

Renewable Storage
Stores solar or wind energy when available and releases it during higher demand periods onsite.
No-Grid Power
Island mode supplies electricity to sites with limited grid access or no connection available nearby.

Cost Control
Stores energy during lower-price periods and supports site use when demand or prices increase later.
Quiet Operation
Battery storage reduces generator runtime, supporting lower noise and cleaner temporary site operations for teams.
Approach

Temporary Power Built For Site Flexibility

How It Helps
1
Site Power: Battery storage supplies AC power for construction sites with limited or unstable grid access.
2
Energy Storage: Renewable energy can be stored and released when site demand increases later.
3
Easier Setup: Mobile setup supports fast transport, lower generator runtime, and quieter temporary operations.
