14.336kWh High-Capacity Energy Storage

The Lithium Valley W15-5A provides 14.336kWh (14,336Wh) of nominal energy storage from its 51.2V 280Ah configuration.

Its large storage capacity makes it suitable for customers who need more stored energy for daily solar consumption, backup power, and off-grid applications.

Solar energy generated during the day can be stored in the battery and used later when solar production is reduced or unavailable.

The battery is suitable for:

Large residential solar systems
Home backup power
Hybrid solar installations
Off-grid solar systems
Commercial solar systems
Offices
Shops and businesses
Energy-storage systems
Backup power applications

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

51.2V 280Ah LiFePO₄ Battery

The W15-5A features a 51.2V nominal voltage and 280Ah battery capacity.

It uses Lithium Iron Phosphate (LiFePO₄) technology, which is widely used in solar energy-storage systems due to its long cycle life, thermal stability, reliable energy delivery, and low maintenance requirements.

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

8,000+ Charge-Discharge Cycles

The Lithium Valley W15-5A is specified for more than 8,000 charge and discharge cycles.

This high cycle-life specification makes the battery suitable for applications where frequent daily charging and discharging is required.

With proper installation and operation within the manufacturer’s recommended parameters, the battery is designed to provide long-term energy storage.

Intelligent Battery Management System

The W15-5A features an integrated intelligent Battery Management System (BMS).

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

The integrated BMS is particularly important for high-capacity lithium batteries because it helps manage the battery cells and maintain appropriate operating conditions.

Space-Saving Wall-Mounted Installation

The Lithium Valley W15-5A uses a wall-mounted installation design, allowing efficient use of available floor space.

Despite its large energy-storage capacity, the wall-mounted configuration provides a clean and organized installation for suitable residential and commercial environments.

Professional installation is recommended, with the mounting structure, electrical connections, inverter configuration, and installation environment meeting the manufacturer’s requirements.

High Energy Efficiency and Stable Output

The W15-5A is designed to provide high energy efficiency and stable output for compatible solar energy-storage systems.

Solar energy generated during periods of sunlight can be stored in the battery and delivered later when required.

This allows users to make greater use of solar-generated electricity and potentially reduce reliance on grid power.

Actual system performance will depend on the inverter, solar array, connected loads, installation configuration, and operating conditions.

Enhanced Safety and Thermal Stability

The W15-5A uses LiFePO₄ battery chemistry, providing excellent thermal stability for stationary energy-storage applications.

The integrated intelligent BMS further supports safe and stable operation by monitoring and managing battery conditions.

For maximum safety and performance, the battery should be installed and operated according to the manufacturer’s technical specifications.

Suitable for Large Residential Solar Systems

With 14.336kWh of energy storage, the W15-5A is suitable for larger homes with higher energy requirements.

Depending on the connected loads, stored energy can be used to power appropriately sized household appliances and systems, including:

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

Actual runtime depends on the total load and how long each appliance operates.

Suitable for Commercial Solar Systems

The large capacity of the W15-5A also makes it suitable for commercial applications requiring reliable energy storage.

Potential applications include:

Offices
Retail shops
Small and medium businesses
Workshops
Commercial premises
Service businesses
Solar backup systems

The battery can store excess solar energy and provide stored electricity when solar generation decreases or during grid power interruptions.

Hybrid and Off-Grid Applications

The Lithium Valley W15-5A is suitable for compatible hybrid and off-grid solar systems.

In a hybrid system, solar panels can charge the battery during the day while the stored energy can be used later.

In an off-grid system, the battery can form part of a properly designed solar-plus-storage installation capable of providing energy when solar production is unavailable.

Before purchase and installation, confirm that the inverter supports the battery’s 51.2V voltage class, 280Ah capacity, charging parameters, discharge requirements, and communication configuration.

Low-Maintenance Energy Storage

The Lithium Valley W15-5A is designed for low-maintenance operation.

Lithium battery technology eliminates routine water-refilling requirements associated with conventional flooded lead-acid batteries, helping reduce maintenance demands.

Long-Term Energy Storage

The combination of 14.336kWh capacity and 8,000+ cycles makes the W15-5A suitable for long-term energy-storage applications.

It can help households and businesses store more solar energy and use that energy when required, including during periods of low solar production and power interruptions.

10-Year Warranty

The Lithium Valley W15-5A comes with a stated 10-year warranty, providing additional confidence for customers investing in a long-term solar energy-storage system.

Warranty terms and operating conditions should be confirmed before purchase.
