The VenturePro 250 brings together in a single cabinet the battery rack, the high-voltage box, the BMS, the auxiliary supply, liquid cooling, fire protection and the inverter (PCS). It connects directly at 400 V AC: no technical room to build, no inverter to source separately.
One rack, five modules of more than 52 kWh each, 314 Ah prismatic LFP cells. All assembled and tested in the factory.
- Industrial or commercial site with a low-voltage connection
- Shaving contracted-power peaks
- Storing the surplus of a rooftop solar plant
- Up to 12 cabinets in parallel on one 400 V bus

- Power
- 250 kW
- Ratio
- 2 h
The ratio, in one line: power × duration = energy. A 2-hour system stores twice its power, a 4-hour system four times. For the same energy, a longer ratio needs less conversion power — and targets other revenue.

We size it with you.
The grid connection, the contract, the generation already in place: three facts are enough to know whether this range is the right one. If not, we point you to another.
