Larger sites repeat this block. The interfaces inside it are fixed, so scaling up does not reopen the single-line.
Representative specification figures for the current container platform. Project values are confirmed in the datasheet issued with each quotation.
Project record
Each entry states what the site got and when it went live — capacity, location, application and commissioning date, in that order, because that is the order a developer checks them in.
120MWh
Four-hour discharge block co-located with a PV plant, commissioned in two phases. The container rows sit on compacted pads with a fire lane wide enough to drive between them — the layout, not the cell, sets the site footprint.
18MWh
Grid-forming configuration prequalified for primary reserve participation. Prequalification testing was run against the delivered block, not a reference design.
6MWh
Behind-the-meter installation on a constrained industrial connection, dispatched against the site load profile rather than a market signal.
Representative project profiles illustrating typical configurations and delivery scopes. These are not client records; named references are provided under NDA during commercial discussion.
Product lines
Buying the four lines together means the interfaces between them are specified, not negotiated on site — and one spares contract covers all of them.
Certification
Certificates are issued per model and per market. Each row states the standard, the issuing body, the certificate number and the product line it covers.
| Standard | Issuing body | Certificate no. | Coverage |
|---|---|---|---|
| IEC 62619:2022 | TÜV SÜD | ES-2024-11870 | Cell and battery safety — container platform |
| IEC 62933-5-2 | TÜV SÜD | ES-2024-11902 | System safety — grid-connected ESS |
| UL 9540A | UL Solutions | UL-9540A-4417 | Thermal runaway fire test — cell, module, unit |
| CE / EN 50549-1 | DEKRA | DK-2024-30988 | Grid connection — PCS product line |
Document downloadsNo registration required.
Certificate numbers are specimen values for this demonstration — replace with the issued numbers before publication. A standard name without a number cannot be verified by a compliance reviewer.
On site
Containers, conversion and control arrive specified against one single-line diagram — the interfaces between them are settled before anything reaches the pad.
An asset that runs unattended for a decade is bought on the service contract, not on the datasheet — so the terms are on this page rather than behind a call.
Factory pre-commissioning, site supervision and grid-code compliance testing.
Continuous telemetry with alarm escalation, exportable to owner SCADA.
Regional spare holding for modules, PCS boards and cooling components.
Ten-year system warranty with a contractual capacity retention schedule.
Project enquiry
Connection voltage, required duration, grid code and site constraints are enough to return an indicative single-line and equipment list.
Phone number and registered address are demonstration placeholders — replace with the real entity before publication.
