Wheeled, industrial-grade LiFePO4 power for the places fixed wiring can't reach — construction sites, telecom towers, mines, emergency repair and remote O&M. No grid tie-in, no electrician, no permit. Just roll it in and plug in.
PowerBox turns any site, tower or temporary camp into a powered workspace in minutes — no trenching, no switchgear, no fuel run.
Run site lighting, power tools, compressors and the site office off a silent, fume-free unit. No diesel noise complaint, no exhaust in enclosed spaces.
Backup and off-grid power for remote BTS, fiber nodes and comms shelters. Charges from the grid, a solar array or a generator at the site.
Power camps, survey gear, lighting and comms in exploration and small mining operations where the grid stops.
First-in power for utility crews, rescue teams and field hospitals — roll it off the truck and plug in life-safety and comms loads.
Keep diagnostics, testing and comms running during maintenance at substations, plants and remote assets far from a socket.
Temporary power for outdoor events, irrigation pumps, fencing and seasonal agriculture — moved and re-deployed as the job moves.
PowerBox and a fixed cabinet solve different problems. Most commercial buyers end up with both.

All models: 314 Ah LFP cells · 80%–100% DoD · air-cooled · ≤75 dB(A) · -25°C to +50°C · CE / UN38.3 / UL / IEC. Full specs on the PowerBox product page.
Four things a diesel set or a fixed bank can't do at once.
Recharges from a wall socket, a solar array or a generator — keep a remote job powered through a multi-day outage with no fuel run.
Roll it to the work, up a floor, across a site. No skid, no crane, no permanent footprint.
≤75 dB(A) and fume-free — safe inside a site office, workshop or tent where a generator cannot run.
LiFePO4 chemistry, -25°C to +50°C operation, and CE / UN38.3 / UL / IEC for export.
What the spec sheet doesn't say — the build details crews and OEM buyers ask about.
Every PowerBox runs a 314 Ah LiFePO4 (LFP) pack watched by a multi-layer BMS — over-voltage, under-voltage, over-current, short-circuit, over-temperature and passive cell-balancing protection, with CAN / RS485 reporting for fleet and OEM telemetry. It charges three ways: AC wall input (a full ~5–7 h recharge on the 16 kWh unit), an MPPT solar input sized for panel arrays, and generator pass-through so a running genset tops it up while loads draw. The 1,500 W pure-sine inverter drives both tools and sensitive electronics. The sealed, air-cooled enclosure is rated for -25°C to +50°C operation at ≤75 dB(A) fan noise, and is rated ≥3,000 cycles at 80% DoD with low self-consumption so a stored unit holds charge between deployments. For white-label programs we expose the BMS protocol and can re-enclose or re-rate the pack to your market.

One hard rule we state plainly: a portable unit powers appliances through its own outlets only and must never be back-fed into a building's distribution panel — that is unsafe and, in most regions, illegal. For whole-site backup you need a fixed, properly commissioned system. Confirm the exact marks and any regional variants with our team for your target market.
PowerBox is the wheeled, industrial-grade portable power station NovaBESS builds for sites where fixed wiring is impractical: construction, telecom and cell towers, mining and exploration camps, emergency and disaster repair, remote O&M and field service, and temporary power for events or agriculture. It delivers 4.02 / 8.04 / 16.08 kWh from its own outlets — no electrician, no permit, no grid tie-in.
For most temporary and sensitive loads, yes. It is silent (≤75 dB(A)), fume-free and indoor-safe, so it runs inside a site office, workshop or tent where a diesel generator cannot. It will not match a generator for days-long, whole-site prime power, but for tools, lighting, comms, pumps and backup it removes fuel, noise and exhaust entirely.
The 16.08 kWh unit (1,500 W continuous) runs a mixed site load — LED site lighting, a drill/driver rotation, a laptop bank and a small pump — for a full shift or more, and recharges from a wall socket, solar array or generator. The 4.02 and 8.04 kWh units cover lighter or shorter duty. Because it charges from three sources, a multi-day job stays powered without a fuel run.
Yes. PowerBox is offered as a proven white-label model through our OEM / ODM program — your logo, label and packaging, with minimal engineering overhead for fast market entry. We also support custom variants (capacity, enclosure, BMS, protocol). See the OEM / ODM page for the 7-step cooperation process.
Yes. It uses LiFePO4 cells, runs air-cooled at ≤75 dB(A), and operates from -25°C to +50°C. It carries CE, UN38.3, UL and IEC. One hard rule: a portable unit powers appliances through its own outlets only and must never be back-fed into a building's distribution panel — unsafe and, in most regions, illegal. For whole-site backup you need a fixed, properly commissioned system.
