HD 51.2V 100Ah Rack-Mount Energy Storage Battery
Model HD51.2-100 · Industrial & Energy Storage
A 51.2V rack-mount lithium iron phosphate module for solar storage, backup, and off-grid power, delivering 5,120 watt hours per module from prismatic cells in a 17.5-inch 4U stainless case. Up to 62 modules parallel into one bank for over 300kWh, with closed-loop CAN and RS485 comms reporting real state of charge to the inverter.
Nominal Voltage
51.2 V
Nominal Capacity
100 Ah
Total Energy
5,120 Wh (5.12 kWh)
Features
- Scale to 317kWh - parallel up to 62 modules on one bus as the site load or storage target grows
- Closed-loop inverter comms - CAN and dual RS485 ports hand real state of charge and cell data to the inverter
- 6,000 cycles with 70% capacity retained - rated at 80% depth of discharge, so daily cycling still clears well past 15 years
- Integrated 125A breaker - front-panel DC disconnect, so the rack needs no separate breaker per module
- Prismatic LiFePO4 cells in a 17.5-inch 4U stainless steel enclosure
- Compatible inverter protocols: SMA Sunny Island, Sol-Ark, Deye, Victron, Schneider
- 15 year limited warranty
- Applications: solar storage, backup power, off-grid, peak shaving, telecom
