02 / SCOPE

Three product families

BESS cabinet

Battery racks, PCS, thermal management and fire fighting integrated; grid-tied or off-grid.

PV grid-connection panel

Combining, metering and protection in one, matched to a substation or step-up transformer.

PV + storage + EV package

PV substation, BESS cabinet and EV-charging substation combined to capacity and grid requirements.

PV substation

Step-up transformer with HV and LV rooms, matched to inverters and the grid panel.

EV-charging substation

Matched to charging stacks with space for metering, communication and future expansion.

System integration

Single-line diagram, protection scheme and communication network issued together.

A storage project is decided by four things: capacity and duration (kWh / kW), grid voltage, grid-tied or off-grid, and fire requirements. Once those are fixed, the cabinet configuration and the price are essentially fixed too.

03 / LEAD TIME

Lead time

Type	Lead time	Conditions
Standard configuration	25–40 days	Scheme confirmed, cabinet production
With long-lead cells	40–60 days	Cell lead time and project scheduling
With transformer and grid panel	35–50 days	Primary equipment package cycle

04 / FAQ

Frequently asked questions

How is a BESS cabinet different from a distribution panel?

A BESS cabinet contains battery racks, PCS, BMS, thermal management and fire fighting — thermal and safety design are the core. A distribution panel only switches and protects.

Can it be combined with PV?

Yes. PV grid panel, PV substation, BESS cabinet and EV-charging substation can be supplied as one package with a single definition of the primary system and communications.

What is needed for grid connection?

A connection scheme and commissioning acceptance, which vary by local grid company. We provide equipment data, test reports and the grid-panel configuration to support your application.

How is fire protection handled?

Smoke, temperature and combustible-gas detection with clean-agent suppression, plus internal fire partitions and pressure relief, selected per project.

What is the lead time?

25–40 days standard; 40–60 days where cells and other long-lead items are involved.
