Collection: Server Rack Lithium Battery

Server rack lithium batteries deliver high-voltage, high-capacity storage in a standard 19-inch rack form factor for commercial and industrial projects. The range covers 15 models across five voltage tiers: 384 V, 512 V, 640 V, 704 V, and 768 V nominal, with usable energy from about 107 kWh up to 215 kWh. All units use LiFePO4 cells and share the same 280 Ah cell capacity, so the main buying decision is voltage and total energy. Match the battery voltage to your inverter or PCS: 384 V systems pair with common 380 V three-phase commercial inverters, while 768 V systems suit higher-voltage PCS platforms. Check the rack depth carefully; units range from 550 mm deep for the smaller 384 V cabinet to 1,100 mm deep for the higher-voltage tiers. Weight runs from 820 kg to 1,650 kg, so plan floor loading, aisle width, and a forklift or pallet jack path. Communication uses RS485/RS232/CAN, which is standard for BMS-to-inverter links, but confirm the protocol mapping with your integrator because high-voltage BMS pinouts vary by manufacturer.

Rack integration details are critical at this scale. Confirm whether the cabinet uses standard 19-inch rails or a custom sliding tray, and whether the supplier provides bus bars, breakers, and pre-wired control cables. High-voltage strings require qualified electrical contractors and often need arc-flash labeling and insulated tools during service. Schedule preventive maintenance every 6 to 12 months to inspect connections, clean filters, and log cell voltages. Environmental monitoring should track temperature gradients inside the rack; hot spots can shorten cell life. If the project needs multiple racks, ask the supplier for a master-slave BMS topology so the system behaves as one bank.
