2.56kWh 12.8V 200Ah LiFePO4 Lithium Battery For Extended Off Grid Power Storage

2.56kWh 12.8V 200Ah LiFePO4 Battery for Extended Off Grid Power Storage

More Stored Energy on a 12V Battery Platform

This 12.8V 200Ah LiFePO4 battery provides 2560Wh of nominal energy for compatible off-grid, solar backup, UPS and inverter systems. It offers twice the nominal capacity of a 12.8V 100Ah battery while maintaining a low-voltage battery configuration.

The product measures 522 × 242 × 218mm and weighs 20kg net. Buyers can use these values to review the available battery compartment, transport requirements, cable access and supporting surface before purchase.

Where the Additional Capacity Matters

A 2.56kWh battery can be considered when a smaller 1.28kWh unit does not provide enough operating time for the selected loads. It may suit projects with longer evening use, extended communication-equipment operation or a larger group of essential circuits.

Calculate Runtime from Average Power

The 2.56kWh rating represents nominal DC energy. Backup duration should be calculated from the average load rather than from the inverter’s maximum output rating.

Lighting, refrigeration, routers and security systems have different operating patterns. Equipment that runs intermittently should be calculated using expected duty time, while continuous loads should be calculated over the full required period.

Usable energy will be lower than the nominal value after inverter conversion losses, battery settings, cable losses and operating conditions are considered.

Physical Installation and Transport Planning

The package measures 547 × 267 × 268mm and weighs 21kg gross. The battery should be installed upright on a stable supporting surface with access to the M8 terminals and external DC protection.

Its IP65 enclosure supports installation in protected technical areas, but the terminal connections should remain covered and the battery must not be immersed.

2.56kWh Off-Grid Battery FAQ

Is this battery actually 3kWh?

The formal electrical rating is 12.8V and 200Ah, equal to 2560Wh or 2.56kWh.

Can it be connected to a solar panel directly?

No. A compatible solar charge controller or inverter charger is required between the solar array and battery.

Does a larger capacity mean higher inverter output?

No. Battery energy and inverter output power must be evaluated separately.

Can it be placed in an open outdoor area?

A protected location is recommended. Connections and terminals must remain protected, and the battery must not be immersed.

What information is needed for capacity calculation?

Provide the load power, operating hours, inverter efficiency and available charging source.
