 Introducing the Growatt Off-Grid Energy Storage System: Ultimate Power and Flexibility

The Growatt Off-Grid Energy Storage System features a state-of-the-art lithium iron phosphate (LiFePO4) battery with a flexible capacity range from 5.12kWh to 25.64kWh. This advanced system is perfect for residential off-grid battery storage and also ideal for small business and industrial use.

The battery system is modular and equipped with internal plugs, eliminating the need for extra cable connections. All external cables are integrated into one plug, simplifying the connection to the inverter. Each module has an internal plug connection, and the battery pack connects quickly to the inverter with a single cable harness

Unmatched Safety and Durability: The system includes cell security monitoring and balancing for enhanced safety. As a cobalt-free LFP battery, it offers high-temperature resistance, safety, and stability. With up to 6,000 charge cycles, the Growatt ARK 2.5L-A1 LV battery system has an expected service life of more than 10 years. It is designed to efficiently use and manage electrical energy, providing a stable electricity supply and cost-saving opportunities, such as charging the battery during low-priced nighttime hours.

Seamless Integration and Continuous Power Supply: By integrating the system with solar panels or a generator, you can ensure a continuous and reliable power supply 24/7 for your home.

Off-Grid Energy Storage System Includes:

Installation and Delivery: The price includes a basic set of cables, protection disconnectors, and accessories required for a fully operational system. User manuals and a connection diagram are supplied with your order. Mounting is not included—if you require a mounting system, select a suitable option here or contact us for advice.

The system must be installed by a licensed electrician or technician in compliance with all applicable regulations and guidance. For residential properties, please see the guidance here.
