Factory Direct 51.2V 100Ah Rack Mount LiFePO4 Battery 5.12KWh 3U Cabinet Storage Battery Compatible With Most Inverters OEM ODM Available

YUNFAN YF51100LP-HES-CT is a 3U rack-mounted lithium iron phosphate energy storage battery tailored for household solar energy storage systems. It addresses common defects of traditional energy storage batteries, including short cycle life, single communication port limitation, invisible operating data, difficult cabinet installation and poor inverter compatibility. This 51.2V 100Ah 5.12KWh rack battery adopts safe LiFePO4 cells, equipped with an integrated intelligent BMS system that supports cell balancing and full safety protection against overcharge, over-discharge and overcurrent. Dual RS485 & CAN communication ports satisfy various equipment connection demands, while the built-in LCD screen displays real-time voltage, capacity and temperature data for easy monitoring. With a slim 3U sheet metal chassis and IP55 protection grade, it fits standard server racks perfectly and works stably across wide temperature ranges. It has passed UN38.3, MSDS and CE certifications, and supports matching most mainstream inverters on the market, with flexible OEM and ODM customization available for energy storage project partners.

Safe LiFePO4 Cell Chemistry
Lithium iron phosphate cells feature outstanding thermal stability, eliminating fire and explosion risks during long-term energy storage operation, far safer than ternary lithium batteries.

Full-Function Intelligent BMS Protection System
Real-time monitoring of each cell voltage to trigger protection against overcharge, over-discharge and high current; automatic cell balancing reduces voltage deviation to extend whole pack service life. Dual RS485 and CAN communication ports support seamless connection with inverters and monitoring hosts.

3U Ultra-Thin Rack Mount Chassis
Compact 3U sheet metal cabinet design supports standard rack installation, saving indoor equipment room space; IP55 dustproof and waterproof casing adapts to various indoor installation environments.

Built-In LCD Real-Time Parameter Display
Onboard LCD screen visually shows battery voltage, remaining capacity, temperature and working status, allowing users to check operating data without extra detection tools.

Ultra-Long Cycle Service Life
Achieves more than 6000 charge-discharge cycles under standard 0.3C working condition, greatly lowering long-term equipment replacement frequency compared with lead-acid storage batteries.

Wide Compatibility & Full Certifications
Compatible with most mainstream inverters globally; passed UN38.3, MSDS and CE transport & safety certifications, eligible for worldwide project delivery.

Household Off-Grid Solar Energy Storage System
Existing Drawback: Conventional storage batteries only support single communication protocol, cannot match multiple inverters, and lack real-time data display for power management.
Solution: Dual RS485/CAN ports fit most mainstream inverters; LCD screen provides real-time power data to help families rationally utilize solar power generated during daytime for night electricity supply.

Residential On-Grid Backup Power Storage
Existing Drawback: Short-cycle lead-acid batteries need frequent replacement, and thick bulky cabinets occupy large indoor space.
Solution: 6000+ long cycles cut maintenance costs; slim 3U rack-mounted design saves installation space inside household electrical cabinets.

Small Commercial Office Energy Storage Equipment
Existing Drawback: Batteries without dust and water resistance get damaged easily in damp equipment rooms, lacking comprehensive safety protection.
Solution: IP55 metal chassis plus full BMS safety protection, stable continuous power supply for office lighting and office equipment during power outages.

Remote Villa & Cabin Independent Power Supply
Existing Drawback: Ordinary storage batteries fail to discharge normally under low temperature outdoor environments, unable to support all-day power supply.
Solution: Stable discharge performance at -20℃, suitable for all-year-round energy storage use in remote low-temperature areas.
