JM 48V 800Ah 40kWh LiFePO4 Battery for Home Energy Storage

PRODUCT DESCRIPTION

51.2V 800Ah 40kWh LiFePO4 Battery

The JM-JS-51.2V800Ah is a 51.2V 800Ah LiFePO4 battery with 40kWh of energy capacity, designed for home energy storage, solar power storage and backup power applications. With 80% depth of discharge (DoD), an 8000-cycle design and a smart BMS, the battery is built for long-term energy storage use.

For solar installers, distributors and system integrators, this large-capacity LiFePO4 battery provides a practical energy storage option for residential projects that require substantial energy storage capacity and reliable backup power.

High-Capacity 40kWh Energy Storage

With a rated capacity of 40kWh, the battery is designed for residential energy storage applications where a larger energy reserve is required.

The 51.2V 800Ah configuration provides a substantial storage capacity for solar energy systems and backup power applications. This makes it suitable for projects where installers need to consider both daily energy storage and backup requirements.

80% DoD for Usable Energy

The battery supports 80% depth of discharge (DoD).

For an energy storage system, DoD indicates how much of the battery's stored energy can be used during a discharge cycle. An 80% DoD provides a defined usable portion of the battery capacity while supporting the intended operating characteristics of the system.

For installers and system integrators, DoD is an important specification to consider when sizing a battery system according to the customer's daily energy consumption and backup requirements.

8000 Cycles for Long-Term Energy Storage

The JM-JS-51.2V800Ah is specified for up to 8000 cycles.

Cycle life is an important consideration when selecting a battery for a long-term solar energy storage project. A higher specified cycle count can be particularly relevant for systems that are regularly charged and discharged as part of their normal operation.

Combined with the 40kWh capacity, the 8000-cycle specification makes this battery suitable for projects where long-term energy storage operation is an important consideration.

Smart BMS for Battery Management

The battery features a smart Battery Management System (BMS).

The BMS is an important part of a lithium battery system because it manages battery operating conditions and supports the management of the battery during charging and discharging.

For solar installers and system integrators, battery management is an important consideration when integrating a LiFePO4 battery into a residential energy storage system.

Designed for Home Solar Energy Storage

The 51.2V 800Ah 40kWh LiFePO4 battery can be used in applications including:

• Home energy storage
• Solar energy storage
• Solar battery systems
• Backup power
• Residential energy storage

For homes using solar power, the battery can serve as an energy storage component for storing electricity generated by the solar system and providing stored energy when required.

For backup applications, the 40kWh capacity provides a substantial energy storage reserve for residential systems. Actual backup duration will depend on the connected loads, inverter configuration and system operating conditions.

Built for B2B Solar Projects

This battery is designed for customers involved in the deployment of residential energy storage systems, including solar installers, solar distributors and system integrators.

For solar installers, the 51.2V 800Ah configuration provides a defined battery capacity for project design and system sizing.

For distributors, the product combines a clear product specification with common solar energy storage applications.

For system integrators, the 51.2V 800Ah configuration, 40kWh capacity, 80% DoD, 8000-cycle specification and smart BMS provide key technical information for evaluating the battery for residential energy storage projects.
