RCTerra Max 1.0 4000
A twenty foot containerised DC energy storage block, 4,073 kWh, with the battery modules and liquid cooling installed at the factory and a hybrid cooling design that keeps the parasitic load down.
Built for the top end
Factory built, container delivered
Battery modules and the liquid cooling system are pre installed in a standard twenty foot ISO container. What arrives on site is a finished block, not a kit.
Hybrid cooling
A liquid cooling chiller works with HVAC, and supplementary air cooling reduces the power the system spends cooling itself. Less parasitic load means more of the stored energy reaches the site.
Explosion protection to NFPA 69
Explosion proof ventilation compliant with NFPA 69, with detection for both smoke and flammable or explosive gas.
A DC block, not an all in one
The Max is a DC energy storage system. It pairs with an external power conversion system chosen for the site, which is what makes it flexible at utility scale and why the AC rating is set by the inverter you put with it.

Specification
Figures below are taken directly from the RCT Power RCTerra Max 1.0 4000 datasheet, IEC and UL, revision April 2026. This is a DC system, so AC ratings depend on the power conversion system specified with it.
Spec sheets
The RCT Power datasheet covers both the IEC and UL builds. Foundation drawings, transport details and PCS pairing notes are available on request.
Utility scale starts with a conversation
Projects at this size involve network approvals, PCS selection and a construction program. Talk to us early and we will map out what the site actually needs before anything is ordered.
