COMMERCIAL HIGH VOLTAGE PACKS & RACKS
Packs and Racks (with optional Thermal Management System)
Discover’s modular rack-mounted ESS platforms let OEMs build customizable, energy-storage systems for controlled environments or with an optional thermal management system (TMS) for liquid cooling/heating. Certified to UL 9540A, UL 1973, and IE C, each module delivers global safety and reliability. A unified mechanical and electrical interface streamlines design, service, and integration, reducing complexity and accelerating time-to-market for OEM energy-storage solutions.
Applications
High-Voltage DC Foundations. High-voltage DC building blocks using external DC/DC or DC/AC conversion.
Modular Microgrid & Industrial Blocks. Modular energy units for containerized microgrids, hybrid gensets, EV-charging buffers, and industrial peak-shaving systems.
High-Density Grid Support Storage. Dense storage for grid-tied or islanded systems for grid-forming or grid-support functions.
HV Packs for DC Bus Architectures. HV packs for DC bus architectures in power cabinets, traction support, and stationary power conversion.
