SAKO Li-Wall 2.56kWh 25.6V 100Ah Lithium Battery

The SAKO Li-Wall 2.56kWh 25.6V 100Ah Lithium Battery is a wall-mounted energy storage solution for compatible solar installations and backup power systems. It is designed to store electricity for use when solar generation is low or when additional power is needed. Its 25.6V nominal voltage and 100Ah capacity make it important to match the battery with equipment designed for the same voltage range.

The manufacturer’s Li-Wall catalogue identifies the SK-25.6V100Ah model as a lithium iron phosphate (LiFePO4) battery with 2.56kWh total energy. It lists approximately 2.048kWh of usable energy at 80% depth of discharge. Actual performance depends on the battery’s condition, operating settings, and connected equipment.

Reliable Storage for Solar Energy

Solar energy storage allows electricity generated during the day to be used later. When connected to a compatible inverter and charging system, the battery can store energy for selected household loads, helping support power availability when solar panels are not generating enough electricity.

The battery’s nominal energy rating is 2.56kWh, while its listed usable energy at 80% depth of discharge is 2.048kWh. These figures help users estimate the energy available for appliances, although conversion losses and system limits can reduce the energy delivered to AC loads.

Backup time depends on the total load. Small devices and efficient lighting generally use less energy than high-power appliances. Calculate the expected consumption of the equipment you plan to operate before deciding how many batteries your system needs.

Technical Specifications and Protection

The documented SK-25.6V100Ah Li-Wall model uses LiFePO4 battery chemistry and has a nominal voltage of 25.6V. The manufacturer’s catalogue lists a voltage window of 22.4V to 29.2V, a fast-charge voltage of 28.8V, and a float-charge voltage of 28.0V. Its listed maximum continuous charge current is 50A, and its maximum continuous discharge current is 100A.

The battery also includes a smart battery management system (BMS) designed to provide protection against conditions such as overcharging, over-discharging, overcurrent, short circuits, and excessive temperature. The catalogue lists RS485 communication and support for parallel connection of up to 15 units. Confirm compatibility and connection limits with the manufacturer’s instructions before expanding a battery bank.

The published catalogue lists a product size of approximately 414 × 372 × 177mm and a net weight of 24.5kg. The stated protection rating is IP20, so the battery must be installed in an appropriate location that meets its environmental requirements. Check the latest datasheet for the exact unit supplied.

Installation and Battery Compatibility

The SAKO Li-Wall battery should be installed with a compatible inverter or charger that supports its voltage and charging requirements. Incorrect settings, unsuitable wiring, or incompatible equipment can affect battery performance and safety.

Before purchase, confirm the exact model number, battery specifications, communication requirements, mounting method, warranty, and local service availability. Make sure the mounting surface can safely support the battery’s weight and that all electrical protection and cable requirements follow the manufacturer’s instructions.

For users planning solar energy storage, the SAKO Li-Wall 2.56kWh 25.6V 100Ah Lithium Battery offers a compact wall-mounted format and documented LiFePO4 chemistry. Proper compatibility checks and professional installation can help create a dependable storage system suited to your energy requirements.
