Product Description:
This 51.2V 300Ah 15.36KWh floor-standing lithium iron phosphate energy storage battery is designed for household solar energy storage systems. It addresses common drawbacks of split storage solutions such as messy wiring, invisible operating data, limited communication compatibility and poor dust-water resistance. Equipped with an all-round intelligent BMS system, it delivers full safety protection and automatic cell balancing to extend service life over 6000 cycles under 0.3C working rate. Dual RS485 & CAN communication ports match most mainstream inverters, while the built-in LCD screen shows real-time voltage, capacity and temperature data. IP55 metal cabinet with floor-mounted design fits indoor and semi-outdoor installation, passed UN38.3, MSDS and CE certifications, with flexible OEM and ODM customization available.

Applications:
-
Household Off-Grid Solar Energy Storage
Existing Drawback: Separate battery units require complicated wiring, lack unified data display and support only single communication protocol.
Solution: All-in-one floor cabinet with dual communication ports and LCD screen simplifies installation and real-time power management.
-
Residential Grid Power Failure Backup System
Existing Drawback: Short-cycle lead-acid batteries need frequent replacement and cannot work stably in damp semi-outdoor spaces.
Solution: 6000+ long cycles and IP55 waterproof cabinet cut maintenance costs and adapt to various installation environments.
-
Remote Villa & Cabin Independent Power Supply
Existing Drawback: Ordinary storage batteries fail to discharge normally under low temperature winter environments.
Solution: Stable discharge performance at -20℃ meets all-year-round power supply demands for off-grid residences.
-
Small Commercial Workshop Energy Storage
Existing Drawback: Rack batteries occupy extra cabinet space and need complex rack assembly.
Solution: Freestanding floor design saves installation space without additional rack accessories.

Customization:
- Adjust capacity, voltage and energy parameters to match residential and small commercial storage project demands
- Modify BMS protection thresholds, communication logic to cooperate with brand exclusive inverters
- Custom cabinet exterior labels, LCD display content and terminal wiring layout
- Adjust shell size, moving wheel structure and export packaging marks for customer requirements
- Support small trial batch orders and flexible mass production scheduling
Support and Services:
- Pre-sales technical matching: Professional engineers provide inverter compatibility and system configuration consultation within 24 hours.
