Rack-77 represents the pinnacle of indoor energy density, delivering 76.8 kWh of high-voltage storage within a single industry-standard 19-inch rack. By utilizing a 768V nominal architecture, this system is specifically engineered for large-scale commercial and industrial facilities that require the massive capacity of a containerized solution but must maintain an indoor, climate-controlled footprint. With the ability to parallel up to 15 units, facility managers can deploy over 1.15 MWh of storage capacity, backed by a 10-year warranty and a robust ≥4,000 cycle life.
Optimized High-Voltage Architecture (768V): Operating at a higher voltage significantly reduces current flow for the same power output. This allows for thinner cabling, reduced heat losses ($I^2R$ losses), and higher round-trip efficiency, ultimately lowering the Balance of System (BoS) costs for high-power industrial inverters.
Superior Energy Footprint: The PBH-768100 offers 50% more energy capacity than the PBH-512100 in the same physical footprint. This allows for megawatt-hour class storage in space-constrained electrical rooms or data centers without the need for expensive outdoor civil works.
Infrastructure Synergy: Designed for the One Big Beautiful Bill Act (OBBBA) of 2025, the system is verified non-FEOC compliant. This status is critical for CFOs, as it secures Section 48E Investment Tax Credit (ITC) eligibility and mitigates the 10-year recapture risks associated with prohibited foreign sourcing.
The Rack-77 is engineered with a multi-layered safety and thermal management architecture specifically designed for the high-voltage demands (768V) of large-scale indoor deployments. Thermal stability is maintained through active fan cooling, providing forced-convection heat dissipation that prevents thermal localized hot spots within the high-density rack. This physical protection is housed in an IP20-rated enclosure, optimized for controlled indoor environments where high airflow is essential for maintaining cell longevity during sustained 1C or higher discharge cycles.
The 0.5C model adheres to a rigorous hierarchy of safety and performance certifications, ensuring compliance from the individual cell through to the fully integrated utility-scale system. A critical highlight of this platform is its non-FEOC verified supply chain, which specifically qualifies the system for Section 48E Investment Tax Credits (ITC) under current federal energy guidelines. This verification protects your capital by ensuring the project meets the domestic content and sourcing requirements necessary to secure and retain significant tax incentives.
The Rack-77 is a sophisticated high-voltage energy storage platform that bridges the gap between traditional indoor rack systems and utility-scale performance. Its double-wide, 50U cabinet architecture is specifically designed to house the massive energy density required for MWh-class facilities while remaining fully operational in standard, climate-controlled indoor environments.
The intelligence of the Rack-77 is centered on a high-speed CAN bus communication protocol. This choice is critical for high-voltage systems (768V), as CAN bus provides the noise immunity and millisecond-level data rates required to coordinate complex battery clusters.
Native Scalability: The system supports up to 15 parallel units, enabling a total storage capacity of 1,152 kWh (1.15 MWh). The CAN bus architecture ensures that as you add racks, the Master BMS automatically recognizes and synchronizes the new capacity into the site-wide Energy Management System (EMS).
Proactive Lifecycle Management: Integrated remote monitoring provides real-time diagnostics on cell-level voltage and health, while remote configuration allows for over-the-air (OTA) firmware updates. This ensures your BESS remains optimized for changing grid conditions or local utility demand-response programs without requiring an on-site technician.
The Rack-77 utilizes a double-wide 50U cabinet, providing the structural reinforcement necessary to support its nearly 1-ton operational weight while maintaining a standard 19-inch rack-mount profile.

Backed by a 10-year comprehensive warranty that provides essential financial and operational security for high-voltage industrial assets. This warranty is structured to ensure that the system maintains a residual capacity of ≥70% over its ten-year lifespan, assuming operation within the standard parameters of 25°C and a discharge depth of 80% (DOD). By covering both manufacturing defects and performance-based degradation, Pomega ensures that your energy storage project remains a bankable asset for its entire projected service life.
