HJ51.2V-314RT – 16kWh LiFePO4 Battery for Home Solar Energy Storage
HJ51.2V-314RT - 16kWh LiFePO₄ Home Solar Battery | 6000 Cycle Life, 200A Discharge, CAN/RS485 for Inverter Compatibility
The HJ51.2V-314RT is a high-capacity lithium iron phosphate (LiFePO₄) battery designed specifically for residential solar energy storage systems. With 16.076 kWh of usable energy, it stores excess solar power during the day for use at night, during peak electricity rates, or when the grid fails.
Built with Grade A 3.2V 314Ah prismatic cells in a 1P16S configuration, this battery delivers reliable performance over 6000 cycles - equivalent to more than 15 years of daily operation. Its high 200A charge/discharge current supports powerful hybrid inverters, while multiple communication interfaces (CAN, RS485, RS232) ensure seamless integration with leading inverter brands.
The unit also supports parallel expansion with automatic address assignment, allowing you to double or triple storage capacity without complex setup. Whether you are building a new off-grid home, upgrading an existing grid-tied solar system, or adding backup power for critical loads, the HJ51.2V-314RT offers safety, efficiency, and long-term value.
Why Choose LiFePO₄?
Safer: No thermal runaway, no fire risk.
Longer life: 6000 cycles vs. 2000-3000 for other lithium chemistries.
High power: Sustains 200A continuous without overheating.
Eco-friendly: Non-toxic, recyclable materials.
Key Features
High Energy Density - 16.076 kWh in a compact 768×480×300 mm case saves valuable wall or floor space.
Outstanding Cycle Life - 6000 cycles at 80% depth of discharge (DOD) and 25°C. Even after 15 years, the battery retains meaningful capacity.
Flexible Parallel Expansion - Connect up to 15 units (or more) in parallel to reach any capacity. The battery controller automatically assigns each unit a unique address - no dip switches or manual configuration required.
Wide Inverter Compatibility - CAN and RS485 ports support standard LiFePO₄ protocols. Compatible with most major hybrid inverter brands (please confirm protocol details).
High Continuous Current - 200A charge and discharge enables the battery to work with 10kW+ inverters. Perfect for whole-home backup.
Robust Temperature Tolerance - Charge from 0°C to 40°C; discharge from -20°C to 40°C. Suitable for garages, basements, and sheltered outdoor locations.
Comprehensive BMS Protection - Built-in battery management system monitors cell voltage, temperature, and current. Protects against over-charge, over-discharge, over-current, short circuit, and extreme temperatures.
Easy Installation - Wall-mountable or floor-standing. Pre-configured cables and communication ports simplify wiring.
Frequently Asked Questions
What is the usable energy of this battery?
The rated energy is 16.076 kWh. Usable energy depends on the inverter and recommended depth of discharge (80% DOD gives ~12.86 kWh).
How long is the cycle life?
6000 cycles at 25°C with 80% DOD. This equates to approximately 15 years of daily use.
Can multiple batteries be connected in parallel?
Yes, the battery supports parallel expansion. It automatically assigns addresses without manual configuration.
Which communication protocols does it support?
It supports CAN, RS485, and RS232 interfaces for seamless integration with most hybrid inverters.
