Description

The Growatt APX 14.3P-B1 is a high-voltage lithium battery designed for modern residential and small commercial energy storage systems. Built for reliability and scalability, it integrates seamlessly with Growatt hybrid inverters to deliver efficient energy storage, helping users maximise solar self-consumption while providing dependable backup power when needed.

The Growatt APX high-voltage battery system utilises advanced lithium iron phosphate (LFP) technology, offering a safe and stable foundation for energy storage. Designed with flexibility in mind, the system supports scalable capacities from 71.68 kWh up to 200 kWh, making it suitable for residential off-grid applications as well as larger commercial and industrial installations.

Thanks to its modular, stackable structure, installation is straightforward and adaptable to different system sizes. The cobalt-free LFP chemistry provides enhanced thermal stability, strong safety performance, and long operational life. With a service life expected to exceed 10 years, the APX HV battery system helps reduce overall total cost of ownership for long-term energy storage solutions.

The compact stacked configuration keeps installations neat and space-efficient, while the intelligent battery management system continuously monitors performance, enhances safety protection, and ensures smooth communication with compatible Growatt equipment.
