Description

2.56kWh 12.8V 200Ah LiFePO4 Battery with Solar and Wind Energy Storage

This 2.56kWh LiFePO4 battery is the largest 12.8V capacity option in the series. Its 200Ah platform is designed for solar, wind, UPS and off-grid projects requiring a longer energy reserve while remaining within a 12V battery architecture.

The battery can store energy for lighting, communication systems, monitoring equipment and other selected DC or inverter loads. A compatible charger or inverter must be selected separately.

Larger 12V Energy Reserve

The 2560Wh capacity provides four times the nominal energy of the 50Ah version. It is suitable for projects that require longer operating periods without changing to a different nominal battery-voltage platform.

The available operating period depends on load consumption and conversion efficiency. A larger battery does not increase the power rating of the connected inverter or DC equipment.

Higher Charging and Discharging Capability

The listed standard charging current is 40A, with a maximum charging current of 100A. The battery should be charged through equipment that follows the 14.0–14.6V charging-voltage range.

The documented discharge current is 200A, providing additional current capability for compatible higher-demand 12V systems. Cables, protection devices and terminals must be selected for the actual project current.

Project Handling and Installation

The battery measures 525 × 240 × 220mm and weighs approximately 26.8kg. Installers should prepare a stable equipment position with sufficient access for safe handling and cable routing.

The IP55 iron enclosure provides dust and water-jet resistance. For long-term reliability, the battery and electrical connections should remain in a protected, ventilated location without immersion or standing water.

High-Capacity 12V Battery FAQ

What is the main benefit compared with the 150Ah version?

The 200Ah battery provides more stored energy and a higher listed charging and discharging current.

Can it be used in a solar or wind energy system?

Yes, when connected to a compatible controller or inverter that supports the required LiFePO4 charging settings.

Is 2.56kWh the energy available to AC loads?

It is nominal DC battery energy. Inverter losses, load conditions and retained reserve reduce the energy available to AC equipment.

What should be considered when installing the 26.8kg battery?

Prepare a stable location, suitable handling method, protected terminals and cables sized for the project current.

What storage environment is recommended?

The stated storage range is 0°C to 45°C at 60±25% relative humidity.
