Construction site
NV-W50: construction, industry and events
The big one. 5,040 Wh, 5,000 W, expandable to 35.3 kWh: several days off-grid.
- 5,040 Wh
- 5,000 Wcontinuous
- 7,000 Wpeak
- 68 kg
Same steel shell and same wheeled chassis as the NV-W36, with capacity raised to 5,040 Wh and 5,000 W continuous. The model that lasts several days on an off-grid site.

Who it is for
Mines and quarries
Dust, mud, rough ground: IP54 chassis, IP67 sockets, all-terrain wheels. It follows the crew to the working face.
Pumping and emergency response
5,000 W continuous and 7,000 W peak: a sump pump starts and runs without tripping the breaker.
Ports, docks and industry
It replaces the combustion-engine generator set in confined spaces: no CO, no engine, no refuelling.
Key features
- 5,000 W continuous, 7,000 W peak : the most powerful in the range. Compressor, sump pump, concrete mixer and demolition hammer start without tripping the breaker.
- The lowest cost per stored kWh in the range : this is the model that returns the most energy per euro invested.
- Built-in 30 mA RCD and a circuit breaker on each socket: personal protection is built into the machine, not added around it.
- Grade A LiFePO4 battery, automotive-grade cells: 3,000 cycles above 80% capacity, 4,000 cycles above 70%.
- Smart BMS : cell balancing, thermal protection, cut-off on overload and short circuit.
- Built-in MPPT : panels connect directly, with no external charge controller.
- IP54 on the chassis, IP67 on the sockets : the station can stay outdoors.
- 50 Hz switchable to 60 Hz from the front panel: the same machine works on European grids and on 60 Hz grids.
- Simultaneous charging and use : the station supplies power while it recharges.
What it runs
| Equipment | Power | Runtime |
|---|---|---|
| LED site lighting, 4 floodlights | 200 W | 21 h 25 |
| Site office, 2 PCs, printer, router | 400 W | 10 h 43 |
| Site accommodation fridge | 150 W | 28 h 34 |
| Drill driver, small tools | 800 W | 5 h 21 |
| 125 mm angle grinder | 1,200 W | 3 h 34 |
| Electric demolition hammer | 1,600 W | 2 h 41 |
| Circular saw | 1,800 W | 2 h 23 |
| Core drill | 2,200 W | 1 h 57 |
| 2 hp compressor | 1,500 W | 2 h 51 |
| Sump pump | 1,100 W | 3 h 54 |
| 160 A MMA welder | 3,500 W | 1 h 13 |
| Site accommodation heater or cooler | 2,000 W | 2 h 09 |
Runtimes calculated on 85% of rated capacity, with the equipment running continuously. A device that does not run continuously (tools, compressor, fridge) lasts much longer than the value shown.
Outputs and charging
Outputs 2 × 230 V 16 A IP67 + 1 × 32 A industrial · 12 V · USB-A · USB-C
Three ways to charge
- Mains
- full charge ≈ 2 h 30.
- Solar
- Anderson input, built-in MPPT controller: up to 1,440 W of NV panels (6 × NV-S240).
- Generator set
- as a fallback, from a sine-wave generator set.
Simultaneous charging and use: the station supplies power while it recharges.
Compatible with
| NV-S100 | 1 to 6 in series, 600 W |
|---|---|
| NV-S240 | 1 to 6 in series, 1,440 W |
| Usable maximum | up to 1,440 W of NV panels |
Extension batteries
Up to six NV-B5 batteries (5,040 Wh) connect in parallel to the expansion port on the left-hand side, with the station switched off, using the cable supplied. Total capacity rises to 35.3 kWh. The batteries extend run time, never power: choose the model for its power first, then the number of batteries for the duration.
