Solar and extension
Extension batteries
An NV station is not a closed product. When the runtime is no longer enough, add a battery: same LiFePO4 chemistry, one cable. Capacity goes up; output power stays the same.
NV-B2
It recharges on its own. The NV-B2 has its own solar input and its own outputs: set beside the station, it extends runtime without going through the main unit.

How many can I add?
Up to six batteries per NV-W36 or NV-W50.
The NV-C24 and NV-P36 do not take an extension battery.
| Station | Battery | Base capacity | With extensions | Total |
|---|---|---|---|---|
| NV-W36 | NV-B2 | 3,072 Wh | + 6 × 2,048 Wh | 15.4 kWh |
| NV-W50 | NV-B5 | 5,040 Wh | + 6 × 5,040 Wh | 35.3 kWh |
Safety rule
Never connect or disconnect an extension battery while the station is on. Switch off both the station and the battery before plugging in the extension cable.
