Application · Agriculture and pumping

Energy for irrigation and pumping where the grid doesn’t reach.

Extending the grid to a remote pump can be costly, and running a generator means hauling fuel. On top of that, starting a motor takes more power than running it.

Used in: Industry and remote operations · Agriculture and pumping

Questions about the Roxon Mobile 15 kW

What is the Roxon Mobile 15 kW used for?

To power remote sites, construction sites, irrigation pumps, events and lighting without the grid, or to reduce generator hours. It delivers 15 kW three-phase at 380/400 V and 5 kW single-phase at 220/230 V, with 33 kWh of LFP battery at 90 % depth of discharge.

How is the Roxon Mobile 15 kW charged?

With solar panels (up to 30 kW across two 160 to 900 V MPPTs), with the three-phase grid (15 kW) or with a diesel generator that starts and stops via dry contact. With a 20 kVA generator or a 15 kW grid supply, charging takes about 2 hours.

Can several Roxon Mobile 15 kW units be connected in parallel?

Yes. Up to 6 units connect in parallel, for 90 kW and 198 kWh.

In what conditions does the Roxon Mobile 15 kW operate?

Between −20 and 50 °C, with 0 to 100 % relative humidity non-condensing and up to 4,000 m altitude, with derating above 2,000 m. It is IP54, naturally cooled and emits 45 dB or less.
