Dawnice 21 Kwh

Dawnice 21kWh Lithium Battery 51.2V 410Ah is a high-capacity LiFePO₄ (Lithium Iron Phosphate) energy storage solution designed for demanding residential, commercial, and off-grid applications. Built with A-grade LiFePO₄ cells, a built-in 0.5C Battery Management System (BMS), communication capability, and a cycle life of over 8,000 cycles, this battery is designed to deliver reliable and long-lasting energy storage.

The supplied product information refers to this system as a 20kWh battery, while the technical specification states 21kWh at 51.2V and 410Ah. For the product page, the technical specification of 21kWh is used here.

The Dawnice battery features a modular rack-mounted or stackable design, making it suitable for installations where flexible and expandable energy storage is required. Its smart monitoring capability allows users to better manage stored energy and integrate the battery into compatible solar and energy-storage systems.

21kWh High-Capacity Energy Storage

With a stated 51.2V, 410Ah configuration and approximately 21kWh of energy capacity, the Dawnice battery provides substantial energy storage for applications requiring more capacity than standard 5kWh, 10kWh, or 16kWh battery systems.

The large storage capacity makes it suitable for:

• Large residential solar systems
• Commercial buildings
• Businesses
• Off-grid homes
• Remote installations
• Renewable energy systems
• Backup power applications
• Peak-shaving applications

The stored energy can be used when solar generation is unavailable or when additional backup power is required.

Advanced LiFePO₄ Battery Technology

The Dawnice battery uses Lithium Iron Phosphate (LiFePO₄) chemistry, a battery technology widely used for modern solar energy storage.

LiFePO₄ technology is well suited to energy-storage applications requiring repeated charging and discharging, long service life, and stable performance.

The battery uses A-grade cells, providing a high-quality foundation for the energy-storage system.

Over 8,000 Charge-Discharge Cycles

The battery is specified with a cycle life of over 8,000 cycles.

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

This makes the Dawnice 21kWh battery suitable for customers looking for a long-term energy-storage solution for residential, commercial, and off-grid applications.

Built-In 0.5C Smart BMS

The Dawnice battery incorporates a 0.5C Battery Management System (BMS) designed to monitor and manage battery operation.

The integrated BMS helps support safe and reliable battery operation while managing the battery during charging and discharging.

The system also includes communication capability, allowing it to work with compatible energy-management and inverter systems.

Smart Monitoring and Communication

The battery features smart monitoring and communication functionality, providing greater visibility and control over the energy-storage system.

When connected to compatible equipment, communication between the battery and inverter can help support coordinated system operation and energy management.

Inverter compatibility and communication protocols should be confirmed before installation.

Modular Rack-Mounted and Stackable Design

The Dawnice 21kWh battery features a modular rack-mounted or stackable design, making it suitable for different installation environments.

A modular design can simplify system organization and allow energy-storage systems to be configured according to available installation space and power requirements.

The rack-mounted configuration is particularly suitable for dedicated battery rooms, commercial installations, and structured energy-storage systems.

Suitable for Demanding Residential Applications

The high capacity of the Dawnice battery makes it suitable for larger homes with significant energy-storage requirements.

It can be integrated into compatible solar systems to store renewable energy for later use, including during periods of low solar production or power interruptions.

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

Commercial Energy Storage

The Dawnice 21kWh battery is also designed for commercial buildings and business applications where reliable energy storage is required.

It can be used as part of a larger renewable-energy system to store solar power and manage energy consumption.

Its high capacity and modular design make it suitable for businesses looking for a structured battery-storage solution.

Off-Grid and Remote Applications

For remote properties without reliable access to the electricity grid, the Dawnice 21kWh battery can be integrated into a compatible off-grid solar system.

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

This makes the battery suitable for remote homes, facilities, and other off-grid applications with substantial energy-storage requirements.

Peak-Shaving Capability

The Dawnice 21kWh system can also support peak-shaving applications, where stored energy can be used strategically to reduce reliance on grid electricity during periods of higher demand.

This can help businesses and other suitable users better manage their energy consumption when integrated into an appropriately designed energy-management system.

10-Year Warranty

The product specifications state a 10-year warranty, providing additional confidence for customers investing in long-term energy storage.

Warranty conditions should be confirmed before purchase and installation.
