Price on application
Centralized utility systems are engineered, configured and priced per project — the final quotation depends on the number of battery containers (5 or 10 MWh), the medium-voltage interface, PCS and transformer skid, switchgear, civil and grid-connection works, and the site's duty cycle. Tell us your power, energy and application targets and our engineers will scope and price a complete solution.
Why developers choose the centralized system.
Direct MV grid connection
Integrated PCS and step-up transformer skid connect straight to a 35 kV-class medium-voltage bus — no separate customer transformer building required.
Scale energy independently
Add a second battery container to move from ~5 MWh to ~10 MWh on the same 2.5 MW power block — right-size duration to your tariff and duty cycle.
Lower LCOE with 314 Ah cells
Large-format 314 Ah LFP cells cut the levelised cost of storage by 16%+ over the system's operating life.
40% smaller footprint
Containers support side-by-side and back-to-back arrangement, saving up to 40% of the project's footprint.
Multi-layer fire safety
Aerosol suppression, water fire-fighting and explosion-proof ventilation fans protect each container.
Built for harsh sites
IP54 enclosure with C5 anti-corrosion rating and PACK-level IP67, rated −30 to 50 °C for coastal and industrial environments.
