VentureGrid brings together in one 20-ft container the battery, the power conversion, the distribution switchboard, an isolation transformer and the control system (EMS). Inputs for solar and the generator and feeders to the loads are built in, each with its own breaker: on site, you simply connect them, with no extra low-voltage wiring. The whole site is completed in 7 to 10 days.
Two models: VentureGrid 125 (125 kW, 261 kWh) and VentureGrid 250 (250 kW, 522 kWh). The system forms the grid itself, restarts on its own after a total blackout and coordinates panels, battery and generator: it powers a site with no grid, or backs up a grid-connected site with an optional automatic transfer switch.
- Off-grid site: mine, island, farm, village
- Backup for critical loads — factory, hospital, telecom site — with an automatic transfer switch
- Extra capacity on a constrained grid connection, without reinforcement
- Storing surplus solar, exporting the rest to the grid

- Energy
- 522 kWh
- Power
- 250 kW
- Ratio
- 2.1 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.
