51.2V 314Ah 16kWh LiFePO4 Lithium Ion Battery

The JM-HT-51.2V314Ah Lithium Ion Battery is designed for residential energy storage, solar power systems, and backup power applications. With a nominal voltage of 51.2V and a capacity of 314Ah, this LiFePO4 battery provides approximately 16kWh of rated energy storage for homes that need to store solar electricity and maintain access to backup power.

Featuring 80% depth of discharge (DoD), a specified cycle life of 8,000 cycles, a smart Battery Management System (BMS), and plug-and-play installation, the battery is designed to support practical residential energy storage projects.

For solar installers, solar distributors, and system integrators, the JM-HT series offers a battery solution to consider when planning home solar storage and backup systems.

Key Features of the 16kWh LiFePO4 Battery

1. 16kWh Energy Storage Capacity

With a rated energy capacity of approximately 16kWh, this battery is suitable for residential solar energy storage projects that require a substantial stored-energy reserve. Actual backup duration depends on household energy consumption, connected loads, inverter efficiency, and system configuration.

2. 80% Depth of Discharge

The specified 80% depth of discharge (DoD) indicates the portion of nominal battery capacity intended to be used during a discharge cycle. This is an important consideration when sizing a home energy storage system according to daily electricity demand and backup requirements.

3. Specified Cycle Life of 8,000 Cycles

The battery is specified for 8,000 cycles. Cycle life is an important factor when evaluating batteries for systems that undergo regular charging and discharging. Actual service life depends on operating conditions, temperature, charge and discharge rates, and other factors defined by the manufacturer.

4. Smart Battery Management System

The integrated smart BMS manages key battery operating parameters and supports battery operation during charging and discharging. Before installation, confirm inverter compatibility and any required communication settings for the intended system.

5. Plug-and-Play Installation

The battery is described as a plug-and-play solution, supporting a straightforward installation approach. Installation requirements, electrical connections, inverter compatibility, and commissioning procedures should be confirmed against the product manual.

6. 15-Year Design Life and 10-Year Warranty

The product is specified with a 15-year design life and a 10-year warranty. Design life and warranty coverage are different: actual service life depends on usage and environmental conditions, while warranty coverage is subject to the manufacturer's applicable terms and conditions.

Designed for Home Solar Energy Storage

The JM-HT 51.2V 314Ah battery is intended for applications such as:

• Residential solar energy storage

• Home battery storage systems

• Solar power backup

• Residential energy storage projects

• Solar systems requiring battery storage

In a typical solar energy storage setup, electricity generated by solar panels can be stored in a compatible battery system for later use. The actual system design depends on solar generation, household consumption, inverter specifications, and backup requirements.

A Practical Option for Solar Installers and System Integrators

Selecting a battery for a residential project involves more than comparing capacity. Solar professionals also need to consider inverter compatibility, usable energy, installation requirements, communication protocols, warranty conditions, and expected operating conditions.

The JM-HT series provides key specifications—including 51.2V nominal voltage, 314Ah capacity, 16kWh rated energy, 80% DoD, and a specified cycle life of 8,000 cycles—for initial project evaluation.

Solar installers and system integrators should confirm system compatibility before specifying the battery. Distributors can use the model and technical specifications to identify the appropriate product configuration for their customers.
