Lithium Valley 5.12kWh W5-E5 Lithium Battery is a reliable and efficient LiFePO₄ (Lithium Iron Phosphate) energy storage solution designed for residential solar systems, backup power, hybrid inverters, and off-grid applications.

With a 51.2V nominal voltage, 100Ah capacity, and 5.12kWh energy storage capacity, this wall-mounted battery provides dependable energy storage while maximizing available installation space.

The Lithium Valley W5-E5 is designed with a no-display front panel, providing a clean and simple battery design for installations where an integrated LCD screen is not required. Despite its simplified front panel, the battery incorporates an integrated Battery Management System (BMS) for battery monitoring and protection.

With over 6,000 charge-discharge cycles and a 10-year warranty, the W5-E5 is designed to provide long-term energy storage for compatible solar and backup power systems.

5.12kWh Energy Storage Capacity

The Lithium Valley W5-E5 provides 5.12kWh (5,120Wh) of nominal energy storage using a 51.2V 100Ah battery configuration.

The stored energy can be used when solar generation is low or unavailable, making the battery suitable for both solar self-consumption and backup power.

It is ideal for:

• Residential solar systems
• Home backup power
• Hybrid solar systems
• Off-grid installations
• Small commercial applications
• Offices and shops
• Essential-load backup systems

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

51.2V 100Ah LiFePO₄ Battery

The W5-E5 uses a 51.2V 100Ah configuration and Lithium Iron Phosphate (LiFePO₄) battery chemistry.

LiFePO₄ technology is widely used in solar energy-storage systems because of its long cycle life, thermal stability, reliable performance, and low maintenance requirements.

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

Over 6,000 Charge-Discharge Cycles

The Lithium Valley W5-E5 is specified for more than 6,000 cycles.

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

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

No LCD Display Design

One of the key characteristics of the W5-E5 model is its no-display front panel design.

Unlike battery models equipped with an integrated LCD display, this version provides a cleaner and simpler front panel without an onboard screen.

This makes the W5-E5 a suitable option for customers who prefer a minimalist battery design or who monitor their energy-storage system through compatible inverter equipment or other monitoring solutions.

Important: The absence of an LCD display does not mean the battery lacks battery-management functionality. The W5-E5 includes an integrated BMS.

Integrated Battery Management System

The Lithium Valley W5-E5 includes an integrated Battery Management System (BMS) designed to monitor and manage battery operation.

The BMS supports stable battery operation during charging and discharging and provides battery-management functions required for lithium energy-storage applications.

Wall-Mounted Installation

The W5-E5 features a wall-mounted installation design, helping save valuable floor space.

Its wall-mounted format allows for a neat and organized battery installation in suitable residential and commercial environments.

The mounting surface and installation structure should be capable of safely supporting the battery, and installation should follow 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, solar energy can be stored in the battery during periods of solar generation and used later when required.

High Safety and Thermal Stability

The W5-E5 uses LiFePO₄ chemistry, which offers good thermal stability for stationary energy-storage applications.

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

For safe operation, the battery should always be installed and configured according to the manufacturer’s specifications.

Suitable for Hybrid and Off-Grid Solar Systems

The Lithium Valley W5-E5 is designed for use with compatible hybrid and off-grid solar systems.

During the day, solar panels can charge the battery, while stored energy can be used later when sunlight is unavailable or when backup power is required.

Before installation, confirm that your inverter supports the battery’s 51.2V voltage class, charging parameters, discharge requirements, and any required communication configuration.

Low-Maintenance Energy Storage

The W5-E5 features a low-maintenance design, making it a convenient alternative to traditional lead-acid battery systems.

Its lithium construction eliminates routine water-refilling requirements associated with flooded lead-acid batteries.

Ideal for Residential Backup Power

The 5.12kWh capacity makes the W5-E5 suitable for many residential backup applications.

Depending on household energy consumption, it can support appropriately sized essential loads such as:

• LED lighting
• Television
• Wi-Fi router
• Decoder
• Computers
• Refrigerator
• Security systems
• Small electrical appliances

Actual backup time depends on the combined wattage of connected appliances and the duration of use.

Suitable for Small Businesses

The battery can also be used in small offices, shops, and other businesses that need reliable energy storage.

By storing solar energy during periods of production, the battery can provide stored electricity when solar output falls or during grid interruptions.
