10.24kWh High-Capacity Energy Storage

The Lithium Valley W10-5A provides 10.24kWh (10,240Wh) of nominal energy storage through its 51.2V 200Ah configuration.

Its larger capacity makes it suitable for applications requiring more stored energy than a standard 5kWh lithium battery.

The battery can store electricity generated by solar panels during the day and make that energy available later when solar generation is reduced or unavailable.

It is suitable for:

• Large residential solar systems
• Home backup power
• Hybrid solar installations
• Off-grid solar systems
• Commercial solar systems
• Offices
• Shops and businesses
• Backup power applications
• Solar self-consumption systems

Actual backup duration depends on connected loads, inverter efficiency, battery state of charge, and overall system configuration.

51.2V 200Ah LiFePO₄ Battery

The W10-5A features a 51.2V nominal voltage and 200Ah battery capacity.

It uses advanced Lithium Iron Phosphate (LiFePO₄) chemistry, a battery technology widely used for solar energy storage due to its long cycle life, thermal stability, reliable performance, and low maintenance requirements.

The 51.2V configuration is intended for compatible 48V-class hybrid and off-grid solar inverter systems.

More Than 8,000 Charge-Discharge Cycles

One of the major advantages of the Lithium Valley W10-5A is its specified 8,000+ cycle life.

This high cycle-life rating makes the battery particularly suitable for solar energy systems where regular charging and discharging occurs.

With correct installation and operation within the manufacturer’s specified conditions, the battery is designed to provide long-term energy storage and reliable performance.

Intelligent Battery Management System

The W10-5A incorporates an integrated intelligent Battery Management System (BMS).

The BMS helps monitor and manage battery operation during charging and discharging while supporting stable and safe battery performance.

For high-capacity lithium batteries, the BMS is an important component for managing the battery cells and maintaining appropriate operating conditions.

Space-Saving Wall-Mounted Design

The Lithium Valley W10-5A uses a wall-mounted design, allowing efficient use of available installation space.

This makes it suitable for homes, offices, shops, and commercial properties where floor space may be limited.

The wall-mounted design also helps create a clean and organized energy-storage installation.

Professional installation is recommended, with appropriate attention to mounting strength, ventilation, electrical connections, inverter compatibility, and manufacturer installation requirements.

High Charging and Discharging Efficiency

The W10-5A is designed to provide high charging and discharging efficiency, helping users make effective use of stored solar energy.

During periods of strong solar generation, excess electricity can be stored in the battery. When solar generation decreases, stored energy can then be supplied to compatible loads through the inverter.

This makes the battery useful for increasing solar self-consumption and reducing reliance on grid electricity where the system is properly designed.

Excellent Thermal Stability and Safety

The battery uses LiFePO₄ chemistry, providing excellent thermal stability for stationary energy-storage applications.

Combined with the integrated intelligent BMS, the battery is designed to operate safely and reliably within its specified voltage, current, and temperature limits.

The battery should always be installed and operated according to the manufacturer’s technical requirements.

Suitable for Residential Solar Systems

With 10.24kWh of energy storage, the W10-5A is suitable for larger homes and residential properties with higher energy-storage requirements.

Depending on the connected loads, the battery can provide stored energy for appropriately sized appliances such as:

• Lighting
• Televisions
• Refrigerators
• Wi-Fi routers
• Decoders
• Computers
• Security systems
• Internet equipment
• Other household electrical appliances

Actual runtime depends on the total power consumption and operating duration of connected appliances.

Suitable for Commercial Solar Applications

The 10.24kWh capacity also makes the Lithium Valley W10-5A suitable for commercial energy-storage applications.

It can be used in:

• Offices
• Retail shops
• Small businesses
• Commercial premises
• Workshops
• Service businesses

The battery can store solar energy and make it available when solar production decreases or during grid power interruptions.

Supports System Expansion

The W10-5A supports system expansion where applicable, allowing energy-storage capacity to potentially be increased when compatible batteries and system configurations are used.

Expansion should only be performed according to Lithium Valley’s specifications, including approved battery configurations, inverter compatibility, communication requirements, and installation procedures.

This makes the W10-5A suitable for customers whose energy-storage requirements may increase over time.

Hybrid and Off-Grid Solar Compatibility

The Lithium Valley W10-5A is suitable for compatible hybrid and off-grid solar systems.

A properly configured solar system can charge the battery from solar panels, while the stored energy can be used during the evening, at night, or during grid interruptions.

Before purchasing, verify that your inverter supports the battery’s 51.2V voltage class, 200Ah capacity, charging and discharge parameters, and communication requirements.

Low-Maintenance Energy Storage

The W10-5A features a low-maintenance design, making it a convenient solution for modern solar installations.

Compared with conventional flooded lead-acid batteries, lithium batteries do not require routine water refilling, helping reduce ongoing maintenance requirements.

10-Year Warranty

The Lithium Valley W10-5A comes with a stated 10-year warranty, providing additional peace of mind for customers investing in a long-term energy-storage system.

Warranty terms and operating conditions should be confirmed before purchase.
