SAKO Li-Sun 20kWh 51.2V 400Ah Lithium Battery

Store more electricity for your solar system with the SAKO Li-Sun 20kWh 51.2V 400Ah Lithium Battery. Designed for compatible energy storage installations, it helps users retain surplus solar electricity and access stored power when needed. Its high-capacity design makes it a potential solution for homes and businesses with significant energy storage requirements.

Store Solar Energy for Greater Flexibility

Solar energy production changes throughout the day, while electricity consumption may continue after sunset. A compatible lithium battery allows users to store available solar electricity and use it later through a suitable inverter. This can help improve energy management and make solar installations more flexible.

The SAKO Li-Sun 400Ah battery is intended for systems that need a substantial energy reserve. Depending on the connected equipment and system configuration, stored electricity may support household appliances, lighting, computers, and selected commercial loads.

The actual backup time depends on the total power demand, inverter efficiency, usable battery capacity, and remaining charge. Calculate your expected energy usage before selecting a battery, particularly if you need to operate essential appliances during power interruptions.

Advanced Lithium Technology and Protection

SAKO’s official catalogue lists the 51.2V 400Ah Li-Sun battery with LiFePO4 cell chemistry and 20.48kWh of nominal energy. It specifies 18.432kWh of usable energy at 90% depth of discharge. Actual available energy can vary with operating conditions and configured battery limits.

The battery range features a smart Battery Management System designed to manage charging and discharging within supported operating limits. Battery protection and communication features can help support reliable operation when the unit is correctly matched with compatible equipment. Confirm the exact BMS functions and communication options for the specific product being supplied.

Correct installation is essential for safety and performance. Use suitable cables, correctly rated electrical protection, secure connections, and charging settings approved by the manufacturer. Check the inverter’s voltage requirements, charging limits, and supported communication protocol before connecting the battery. A qualified technician should verify compatibility and complete the installation.

A Practical Solution for Solar and Backup Systems

The SAKO Li-Sun 20kWh-class battery can be considered for compatible residential solar installations, hybrid inverter systems, and selected business backup applications. It can help store excess solar electricity for use when generation falls or demand increases, depending on the capabilities of the complete system.

Before purchasing, verify the exact model number, nominal voltage, total energy, usable capacity, charging and discharging current, dimensions, weight, warranty, and after-sales support. These details are especially important when integrating the battery with an existing inverter or expanding an energy storage installation.

The SAKO Li-Sun 20kWh 51.2V 400Ah Lithium Battery offers a substantial storage option for users planning a larger solar power system. Check the official datasheet with the seller to confirm that the supplied battery matches your technical requirements and expected energy consumption.
