Product overview
The smaller configuration delivers 400 kW on grid and 250 kW off grid. The larger configuration is rated at 600 kW in either mode. For a 1.2 MW / 2.58 MWh project, the PCS arrangement and grid connection must be sized for the higher power.
Configuration note: nameplate values help define the starting point. Final usable energy, interfaces, operating limits, document scope, and commercial terms are confirmed for the specific project.

Applications to evaluate
Renewable integration
Validate the duty cycle, site, interfaces, and operating objective before confirming model suitability.
Microgrid storage
Validate the duty cycle, site, interfaces, and operating objective before confirming model suitability.
Selection, supply scope and engineering notes
- Provide the required power separately for grid-connected and islanded operation.
- Confirm transformer scope, protection coordination and usable energy at the site.
Confirm the project responsibility matrix
The product rating does not define a turnkey project scope. The quotation should identify who supplies, integrates, installs, commissions, and accepts each applicable item.
- Battery system, BMS, thermal management, enclosure, internal protection, and communications
- PCS, EMS or SCADA, transformer, switchgear, metering, external protection, and grid interface
- Fire strategy, foundations, lifting, cable routing, installation, testing, and commissioning
- Documentation, training, spare parts, warranty conditions, maintenance, and acceptance records
Technical documents
Use the public page and any available procurement brief for initial comparison. Request the applicable controlled data sheet, drawings, test or certificate evidence, and commercial documents for the exact quoted model and destination.
Frequently asked questions
What buyers ask before specifying a battery system
Answers cover the information needed to confirm configuration, operating conditions, documentation, price, and delivery.
Why are prices not published on the product pages?
The listed products are project-configured B2B systems or battery series. Pricing depends on configuration, quantity, accessories, packaging, destination, and commercial terms, so quotations are prepared against a defined project scope.
What is the production and delivery lead time?
Lead time is confirmed only after the configuration, quantity, compliance documents, packaging, and destination are known.
