BESS products for utility, C&I and microgrids.
The ROCAS product platform combines battery systems, power conversion, medium-voltage integration, controls and project-specific engineering. The complete September 2026 catalog is available below.
22 pages of BESS and smart-microgrid solutions.
The uploaded catalog covers standalone BESS, mining and island microgrids, AI data-center power architecture, C&I systems, HVDC charging, transformer backup, immersion-cooled products, conventional liquid-cooled products and MV skids.
Containerised storage and MV integration.
4.5 MWh battery container
Utility-scale immersion-cooled architecture with direct dielectric-fluid thermal management.
5 MWh battery container
Liquid-cooled utility-scale BESS for standard containerised deployment.
String MV Skid
Modular PCS and MV architecture for distributed block design and project scaling.
Centralized MV Skid
Centralised medium-voltage integration for project-specific electrical architecture.
All-in-one systems and hybrid energy applications.
Product selection depends on load profile, grid conditions, required autonomy, cycling strategy, space and lifecycle economics.
261 kWh All-in-One ESS
125 kW / 261 kWh class system with flow-immersion thermal management and cabinet-level monitoring architecture.
261 kWh All-in-One ESS
125 kW / 261 kWh class system using plate heat-exchanger liquid cooling for conventional C&I applications.
PV + storage All-in-One
Integrated hybrid architecture for commercial, industrial and remote-energy applications.
Specifications are confirmed model by model.
The current catalog includes immersion configurations with manufacturer-rated cycle-life figures of 10,000 and 15,000 cycles. Ratings, warranties, usable capacity, C-rate and safety parameters remain specific to the selected product and binding supplier documentation.
ROCAS is the integrator, not a single-vendor platform.
Cell, PCS, MV and control technologies are selected against project requirements, bankability, European compliance, availability and lifecycle value.
