The RACK-51 provides a high-density, high-voltage energy storage solution designed for seamless integration into 19-inch rack environments. Delivering 51.2 kWh of capacity within a 50U cabinet footprint, this system is engineered for commercial and industrial applications where scalability and infrastructure compatibility are paramount. With the ability to parallel up to 15 units, the platform scales effortlessly to 768 kWh, providing a future-proof energy asset backed by a 10-year warranty and a robust ≥4,000 cycle life.
Infrastructure Synergy: By utilizing the industry-standard 19-inch form factor, the PBH-512100 eliminates the need for specialized civil works or custom enclosures. It can be deployed directly into existing IT server rooms or electrical closets, significantly reducing upfront installation costs.
Tax Credit Security (Non-FEOC): In accordance with the One Big Beautiful Bill Act (OBBBA) of 2025, the PBH-512100 is verified as non-FEOC compliant. This ensures that projects meet the 55% non-prohibited material threshold required for Section 48E Investment Tax Credit (ITC) eligibility in 2026, protecting your investment from federal recapture penalties.
Intelligent Scalability: The “Pay-as-you-Grow” architecture allows facility managers to add capacity incrementally. Integrated CAN bus and RS485 communication ensure that new modules synchronize automatically with the master BMS, allowing for expansion without system-wide downtime.
The RACK-51 is designed with a comprehensive safety and environmental management suite to ensure stable, long-term performance in high-density commercial and industrial environments. To maintain optimal cell health, the system utilizes active fan cooling, providing forced-convection thermal management that prevents heat buildup during sustained high-discharge cycles. This physical protection is housed in an IP20-rated enclosure, specifically optimized for secure indoor installations such as data centers, telecom hubs, and dedicated electrical rooms.
The system’s intelligence layer features an advanced Battery Management System (BMS) with multi-point protections against under-voltage (UV), over-voltage (OV), over-current (OC), and temperature extremes (UT/OT). This BMS is directly integrated with a Master Circuit Breaker, ensuring millisecond-level isolation of the high-voltage DC bus in the event of a short-circuit or critical fault. For at-a-glance monitoring, the front panel includes clear LED indicators that provide real-time visual feedback on system Alarm status, operational Run mode, and current State of Charge (SOC).
RACK-51 is engineered for deep integration into modern industrial ecosystems, combining high-speed communication with a robust mechanical build. At the core of its intelligence is a CAN bus communication protocol, which provides the low-latency, high-reliability “backbone” required for real-time Battery Management System (BMS) synchronization. This architecture allows for massive scalability, supporting up to 15 parallel units to create a centralized energy bank of 768 kWh while maintaining simplified, single-point monitoring for the entire array.
| State | Temperature Range | Strategic Importance |
| Normal Operating | 25°C | The baseline for all performance, warranty, and cycle-life specifications. |
| Charging | 0°C to 50°C | Critical Safety: Charging below 0°C is prohibited to prevent “lithium plating,” which causes irreversible capacity loss. |
| Discharging | -15°C to 50°C | Expanded range for cold-start reliability; integrated heaters or insulation may be required for sub-zero discharge. |
| Storage | -10°C to 60°C | Wide tolerance for transport and idle periods; optimal health is maintained at 10°C–35°C at 50% SOC. |
Every Pomega is supported by a robust 10-year comprehensive warranty, providing long-term asset protection for commercial and industrial operators. This performance guarantee ensures that the system will maintain a minimum of 70% State of Health (SOH) over the warranty period, protecting your investment against excessive capacity degradation. By covering both manufacturing defects and functional performance, Pomega provides the financial and operational certainty required for mission-critical energy infrastructure.
