Portable Power for Off-Grid & Construction Sites

PowerBoxOff-gridConstructionNo diesel

When there is no grid — or the grid is unreliable — a wheeled, plug-and-play battery delivers silent, fume-free power you roll to the job. NovaBESS PowerBox ships in 4 / 8 / 16 kWh blocks with AC + DC multi-port output, ready to run the moment it arrives.

Best fit: PowerBox is built for places a wall of batteries cannot go — construction sites, mines, telecom towers, field events and emergency response. It needs no grid tie-in and no diesel, runs at 4 / 8 / 16 kWh, and connects with standard AC and DC outlets so tools and equipment start immediately.

Why battery beats diesel on site

Diesel generators are the default on remote sites, but they carry hidden cost: fuel delivery, noise, fumes, maintenance and carbon compliance. A lithium portable power station removes all four. For a typical single-shift site running lights, drills, pumps and a site office, a 4–8 kWh unit covers core loads; add a second module for heavier or multi-shift work. Because PowerBox is wheeled and plug-and-play, one person moves and starts it — no crane, no electrician.

Where PowerBox earns its keep

PowerBox specifications

ModelCapacityOutputBest for
PowerBox 44 kWhAC + DC, multi-portSingle-shift tools, lighting
PowerBox 88 kWhAC + DC, multi-portBusy site, site office

All three are plug-and-play, recharged from grid, solar or a generator, and certified to IEC 62619, CE and UN38.3 for international shipping. Cloud monitoring lets a site manager check state-of-charge remotely.

Frequently asked questions

Can PowerBox run power tools on a construction site?

Yes. With AC + DC multi-port output it runs standard site tools, lighting and a temporary office. Choose 4 kWh for light single-shift use, 8–16 kWh for busier or multi-shift sites.

Does it need a grid connection to work?

No. PowerBox is off-grid by design — it delivers power wherever you roll it. You recharge it later from grid, solar or a generator.

How is it shipped internationally?

It is certified to UN38.3 (the UN transport test for lithium batteries), CE and IEC 62619, which streamlines air and sea freight versus uncertified units.
