It is an ideal option for homeowners and small businesses looking for a low-maintenance alternative to conventional lead-acid batteries.

The Lithium Valley W3-5D combines LiFePO₄ battery technology, an integrated Battery Management System (BMS), long cycle life, thermal stability, and stable charging and discharging performance to provide reliable energy storage for everyday solar applications.

2.56kWh Energy Storage Capacity

The Lithium Valley W3-5D provides 2.56kWh of nominal energy storage from its 25.6V 100Ah battery configuration.

The stored energy can be used to provide backup power when solar generation is unavailable or during electricity interruptions.

It is suitable for applications such as:

• Home solar systems
• Backup power systems
• Hybrid inverter systems
• Off-grid solar installations
• Small offices
• Shops and small businesses
• Essential-load backup systems

The actual backup time depends on the power consumption of the connected appliances and the efficiency of the overall system.

25.6V 100Ah LiFePO₄ Battery

The battery features a 25.6V nominal voltage and 100Ah capacity, making it suitable for compatible low-voltage solar and energy-storage systems.

Its LiFePO₄ chemistry provides stable and reliable performance for repeated charging and discharging.

Lithium Iron Phosphate technology is widely used in solar energy-storage applications because it offers a combination of long cycle life, thermal stability, and low maintenance requirements.

Over 6,000 Charge-Discharge Cycles

The Lithium Valley W3-5D is specified for over 6,000 cycles.

A high cycle-life rating is important for solar batteries because the battery may be charged and discharged regularly as part of daily energy storage.

This allows the battery to serve as a long-term energy-storage solution when properly installed and operated within the manufacturer’s specifications.

Integrated Battery Management System

The W3-5D includes an integrated Battery Management System (BMS) designed to monitor and manage battery operation.

The BMS helps support stable battery operation and provides protection during charging and discharging.

This is particularly important for lithium batteries because the BMS helps manage the battery cells and contributes to safe and reliable operation.

Wall-Mounted Design

The Lithium Valley W3-5D features a wall-mounted design, making it suitable for installations where efficient use of space is important.

The wall-mounted format can provide a neat and organized battery installation for suitable residential and small commercial environments.

Professional installation is recommended to ensure the mounting surface, electrical connections, inverter compatibility, and installation environment meet the manufacturer’s requirements.

Stable Charging and Discharge Performance

The battery is designed to provide stable charging and discharge performance for compatible solar and backup systems.

When connected to a properly configured inverter and solar system, it can store energy generated during the day and make that energy available when required.

High Safety and Thermal Stability

The Lithium Valley W3-5D uses LiFePO₄ battery chemistry, which is known for its thermal stability and suitability for stationary energy-storage applications.

The integrated BMS further supports safe battery operation by managing the battery during charging and discharging.

Low-Maintenance Energy Storage

Unlike traditional lead-acid batteries that may require regular maintenance, the Lithium Valley W3-5D is designed as a low-maintenance energy-storage solution.

Its lithium construction provides convenient energy storage without the routine water-refilling requirements associated with flooded lead-acid batteries.

Suitable for Hybrid and Off-Grid Solar Systems

The W3-5D can be integrated into compatible hybrid and off-grid solar systems.

Solar panels can charge the battery during periods of solar generation, while the stored energy can be used later when solar production decreases.

Before installation, always confirm that the battery voltage, charging parameters, communication requirements, and battery capacity are compatible with the selected inverter.

Ideal for Residential Backup Power

The compact 2.56kWh capacity makes the Lithium Valley W3-5D suitable for smaller residential energy-storage applications.

Depending on the system design and household loads, stored energy can be used for essential appliances such as:

• LED lights
• Wi-Fi routers
• TVs
• Computers
• Decoders
• Small electronics
• Other appropriately sized loads

Actual runtime depends on the total wattage of connected appliances and how long they are used.
