What the storage system connects to.
A battery only earns its place through the equipment around it: the supply it charges from, the switchgear that isolates it, the loads it protects and the sources a controller must coordinate.

Power path
- Utility gridAbsent on an off-grid site.
- TransformerService transformer, or an isolation transformer for an island.

- Switchgear and transfer deviceIsolates the system and moves the site between grid and island.

- This productOmniStax SeriesStores energy as DC and delivers it through the PCS.

- Site loadsCritical loads first when the battery is the only source.
Other sources the controller coordinates
- SolarCharges the battery or serves load directly.
- Diesel generatorBackup, or the second source on an island.
- From the OmniStax SeriesDispatch rules decide which source serves which load.
From pack to power station, as the principal publishes them
Storage is built in steps. Each step adds energy, voltage and the equipment needed to connect it.
- Battery pack

14 kWh at 51.2 V DC. The building block.
- Battery rack

215 kWh at 768 V DC. Packs in series, fitted inside an enclosure.
- Cabinet system

105 kW with 215 kWh. Battery, PCS and controls in one outdoor cabinet.
- Battery compartment

Up to 5,016 kWh at 1,331.2 V DC. DC only; converts in a separate station.
- PCS and MV station

Up to 5,000 kW, stepped up to 10, 20 or 35 kV.
Application context
Where this product fits.
Typical applications for this product family. Fit still depends on the exact service, duty, operating objective and approved configuration, so treat these as starting points rather than recommendations.
- 01Peak shaving
- 02Solar self-consumption
- 03Critical-load backup
- 04Diesel optimization
- 05Renewable smoothing
- 06Grid-tied storage on a constrained feeder
Before an offer
What Metro Power confirms before OmniStax Series is offered.
Three steps, in the order they happen: what the public record already shows, what your project must confirm, and the controlled documents that close the loop.
01Professional documentation
One product identity. Five controlled evidence gates.
This schedule shows what the public record supports and what Metro Power must still match before the product becomes a technical or commercial commitment.
02Configuration gate
What must be confirmed before an offer.
Capacity, savings and backup duration require validated interval load, site and operating data; monthly consumption alone is insufficient. Frequency, service voltage and the largest motor to be started are confirmed before any model is proposed.
- 0112 months of bills and tariff
- 02Interval load data
- 03Critical loads and outage history
- 04Solar/generator details
- 05Single-line and transformer data
- 06Site, fire and interconnection constraints
