The Sunsynk 5.12kWh X Series Low Voltage Battery is a compact, high-performance energy-storage solution designed for residential and small commercial solar systems. With a 51.2V nominal voltage and 100Ah capacity, the battery provides approximately 5.12kWh of nominal energy storage, making it an excellent choice for storing excess solar energy and providing backup power when grid electricity or solar generation is unavailable.

The X Series battery is designed to work as part of a compatible Sunsynk low-voltage energy-storage system, allowing solar energy generated during the day to be stored and used during the evening, at night, or during power interruptions.

Its IP65-rated enclosure provides protection against dust and water ingress, helping to improve durability and reliability when the battery is installed in an appropriate environment and according to the manufacturer’s installation requirements.

The 5.12kWh capacity also makes this battery a practical building block for expandable battery systems where additional storage capacity may be required.

Key Features

🔋 5.12kWh Energy Storage Capacity

The battery provides approximately 5.12kWh of nominal energy storage. This capacity can be used to store energy generated by a solar PV system for later consumption.

Stored energy can be used to:

• Power essential household appliances
• Reduce reliance on grid electricity
• Provide backup power during outages
• Increase solar self-consumption
• Shift energy consumption to different periods
• Improve overall energy independence

⚡ 51.2V Low-Voltage System

The Sunsynk X Series battery operates at a 51.2V nominal voltage, making it suitable for compatible low-voltage hybrid inverter and energy-storage applications.

Its low-voltage architecture is particularly suited to residential solar systems where reliable battery storage is required without moving to a high-voltage battery architecture.

🔋 100Ah Capacity

The battery has a rated capacity of 100Ah, providing a substantial energy reserve in a compact energy-storage package.

The combination of 51.2V and 100Ah results in approximately:

51.2V × 100Ah = 5.12kWh

This provides a convenient capacity for residential backup and solar-energy storage applications.

🛡️ IP65 Protection Rating

The battery features an IP65-rated enclosure, offering protection against:

• Dust ingress
• Water jets from applicable directions
• Environmental exposure within the manufacturer’s permitted installation conditions

The IP65 rating makes the battery suitable for a wider range of installation environments than equipment with lower ingress protection. However, the battery should still be installed in accordance with Sunsynk’s specified environmental and installation requirements.

☀️ Solar Energy Storage

The battery is designed to store surplus electricity generated by solar panels.

During periods of high solar production, excess energy can be directed into the battery rather than being wasted or exported, depending on the system configuration.

When solar generation decreases, the stored energy can then be supplied to the connected loads.

This allows homeowners and businesses to make greater use of their own solar-generated electricity.

Benefits of the Sunsynk 5.12kWh X Series Battery

Increase Solar Self-Consumption

Solar panels typically generate the most electricity during daylight hours, while household electricity consumption may continue into the evening.

The Sunsynk battery allows surplus daytime solar energy to be stored and used later, helping to increase the percentage of solar energy consumed on-site.

Backup Power During Grid Outages

When installed with a compatible Sunsynk hybrid inverter and correctly configured backup system, the battery can supply stored energy to designated loads during a grid outage.

This can help keep important equipment operating, including:

• Lights
• Wi-Fi routers
• Televisions
• Computers
• Security systems
• Refrigerators
• Selected household appliances
• Other essential loads within the system’s available power capacity

The actual backup duration depends on the connected load, battery state of charge, inverter configuration, and operating conditions.

Reduce Grid Dependence

By storing excess solar energy and using it when required, the battery can reduce the amount of electricity purchased from the utility grid.

This is particularly useful for customers looking to improve energy independence and optimise their solar investment.

Energy Management

The battery can form part of a broader energy-management strategy, allowing stored energy to be used according to the requirements of the solar system, inverter, household, or commercial installation.

Expandable Energy Storage

The 5.12kWh X Series battery can be used as an individual battery or as part of a larger compatible battery-storage system, subject to the applicable Sunsynk inverter, battery, communication, and installation specifications.

Multiple compatible battery units can potentially be combined to increase the total available storage capacity.

For example:

Number of Batteries	Nominal Storage Capacity
1 × 5.12kWh	5.12kWh
2 × 5.12kWh	10.24kWh
3 × 5.12kWh	15.36kWh
4 × 5.12kWh	20.48kWh

Important: Actual supported battery quantities, connection arrangements, inverter compatibility, and communication requirements must be confirmed against the latest Sunsynk specifications before installation.

Typical Applications

The Sunsynk 5.12kWh X Series LV Battery is suitable for a variety of applications, including:

Residential Solar Systems

Ideal for homes requiring additional energy storage to make better use of their solar PV generation.

Backup Power

Provides stored energy for essential loads during utility interruptions when connected to a suitable backup-capable inverter system.

Solar Self-Consumption

Stores excess solar generation during the day for use during periods of reduced solar production.

Small Commercial Systems

Can be used in small offices, shops, workshops, and other businesses requiring battery storage.

Hybrid Solar Systems

Designed to form part of a compatible Sunsynk hybrid inverter and battery-storage solution.

Energy Cost Management

Stored energy can potentially be used to reduce grid consumption during periods when electricity costs are higher, depending on the applicable tariff and system configuration.

Ideal for Essential Loads

A 5.12kWh battery is particularly useful for systems where the objective is to provide backup power for selected essential circuits rather than an entire property.

Depending on the inverter and load requirements, the stored energy can be allocated to essential equipment such as:

• Lighting
• Refrigeration
• Internet and networking equipment
• Security systems
• CCTV
• Computers
• Home entertainment
• Small appliances
• Selected office equipment

The actual operating time will depend on the combined power consumption of the connected equipment.
