Key Features

5.12kWh Energy Storage Capacity

The battery provides approximately 5.12kWh of nominal energy storage from a 51.2V, 100Ah battery configuration. It can store excess solar energy during the day and supply stored power when solar production is unavailable.

Advanced LiFePO4 Chemistry

The battery uses Lithium Iron Phosphate (LiFePO4) technology, which offers:

• Excellent thermal and chemical stability
• Long cycle life
• High energy efficiency
• Reliable performance
• Low maintenance requirements
• Excellent suitability for daily solar cycling

LiFePO4 chemistry is widely used in stationary energy-storage applications because of its combination of safety, durability, and long operating life.

Long Cycle Life

The battery is rated for approximately 6,000 deep-discharge cycles at 80% DoD, making it suitable for frequent daily charging and discharging.

When used under appropriate operating conditions, this provides the potential for many years of service in solar energy-storage applications.

Integrated Battery Management System

The built-in 100A BMS continuously monitors and manages important battery parameters to help protect the battery during operation.

The BMS helps provide protection against conditions such as:

• Overcharging
• Over-discharging
• Excessive current
• Short circuits
• Abnormal operating conditions
• Cell voltage imbalance

CANBUS Communication

Integrated CANBUS communication allows the battery to communicate with compatible inverters and energy-management systems.

This enables the inverter and battery to exchange important information such as:

• State of charge (SOC)
• Battery voltage
• Charge and discharge current
• Battery status
• Protection status
• BMS information

Proper CANBUS communication and configuration should be confirmed before installation to ensure compatibility with the selected inverter.

Modular and Scalable Design

The compact 3U rack-mount form factor makes the battery suitable for installations where space is limited.

Multiple compatible batteries can be configured together in a properly designed energy-storage system, allowing storage capacity to be increased as energy requirements grow.

High Discharge Capability

The battery supports a maximum continuous discharge current of 100A, with a short-duration pulse capability of up to 150A for 300 milliseconds.

This makes the battery suitable for applications requiring reliable power delivery and handling of short-duration higher-current demands.

Flexible Charging

The battery supports:

• Standard charging: 50A / 0.5C
• Maximum charging: 100A / 1C

At the standard 50A charging rate, the battery can be recharged efficiently for typical solar-storage applications.

Wide Operating Temperature Range

The battery is designed for a broad range of operating conditions:

• Charging: 0°C to 45°C
• Discharging: -20°C to 55°C
• Storage: -10°C to +45°C

The battery should always be installed in an environment that complies with the manufacturer’s temperature, ventilation, and installation requirements.

Ideal Applications

The BSL 5.12kWh battery is suitable for a wide range of energy-storage applications, including:

• Residential solar energy storage
• Solar backup power systems
• Off-grid solar installations
• Hybrid solar systems
• Load-shedding backup
• Small commercial energy storage
• Telecommunications backup
• UPS and critical-load applications
• Renewable energy storage
• Battery banks for hybrid inverter systems

Solar Energy Storage

When integrated with a compatible solar inverter, the BSL battery can store excess solar energy generated during daylight hours.

The stored energy can then be used during:

• Evening periods
• Night-time operation
• Load-shedding
• Grid outages
• Periods of low solar generation
• Peak-demand periods

This can help improve solar self-consumption and reduce dependence on grid electricity.

Compact 3U Rack-Mount Construction

The 3U form factor provides a practical solution for rack-mounted energy-storage systems. Its compact design helps optimise installation space while allowing additional compatible battery modules to be added when more storage capacity is required.

The battery is well suited to professional installations using suitable battery racks, cabinets, or other manufacturer-approved mounting arrangements.

Safety and Reliability

The BSL battery incorporates LiFePO4 cell technology and an integrated BMS to provide a high level of operational safety and battery protection.

The use of UL-listed prismatic LiFePO4 cells further supports the battery’s suitability for demanding energy-storage applications.

For safe operation, installation should be carried out by a suitably qualified installer, with correct cable sizing, protection devices, inverter configuration, battery communication, and mounting arrangements.

Warranty

The battery is supplied with a 12-year warranty when used with compatible BSL inverters and batteries, subject to the manufacturer’s warranty terms and conditions.

Warranty coverage may depend on correct installation, commissioning, operating conditions, battery configuration, and use of compatible equipment.
