Growatt AXE – The Flexible and Powerful Energy Storage Solution from 5 kWh to 50 kWh

The Growatt AXE series offers you a groundbreaking solution for storing solar energy or other renewable energy sources. Whether you operate a smaller household or need to store large amounts of energy in the commercial sector: With Growatt AXE, you can easily scale the capacity from 5 kWh to 50 kWh. Thanks to its modular design, the Growatt AXE storage solution grows with your needs and can be easily expanded at any time.

In developing the Growatt AXE series, great emphasis was placed on easy installation and high safety. The fully stackable modules require no complex cable connections: they are stacked on top of each other and automatically recognized. Additionally, you benefit from a cobalt-free LiFePO₄ cell chemistry, which is characterized by high thermal stability, longevity, and environmental compatibility.

The Growatt AXE energy storage systems are particularly uncomplicated not only during initial installation but also in operation. An integrated battery management system (BMS) protects against deep discharge, automatically detects undervoltages, and performs an autonomous restart if necessary. Through the communication interfaces (CAN/RS485), all important parameters of the Growatt AXE batteries can be viewed at any time and maintained remotely. Even firmware updates can be conveniently applied remotely to keep the functionality of your Growatt AXE system up to date.

Another highlight of the Growatt AXE series is the high depth of discharge of up to 92%. This allows you to truly utilize a large portion of the stored energy and significantly increase your self-consumption. The soft-start function protects your system from voltage spikes, thus increasing the lifespan of all components. The Growatt AXE modules can also be interconnected in multiple clusters (up to 8), achieving a total energy capacity of up to 400 kWh – ideal for extensive applications in commercial and industrial projects.

At the same time, the Growatt AXE series scores with its quick and easy installation, which takes an average of only 30 minutes. This not only saves you time but also installation costs. The well-thought-out, compact design ensures that the Growatt AXE batteries can be easily accommodated and safely operated even in confined spaces.

Whether for single-family homes, multi-family homes, small businesses, or larger projects: With Growatt AXE, you are opting for a scalable, reliable, and modern storage solution that offers you the highest security, flexible expandability, and smart monitoring functions in one product.

Technical Specifications of the Growatt AXE Series (5 kWh to 50 kWh)

The following table provides the key technical parameters of the individual Growatt AXE variants. Each Growatt AXE unit consists of stacked battery modules (AXE 5.0L), each with a capacity of 5 kWh. The more modules connected to a system, the greater the available total capacity – from 5 kWh (1 module) to 50 kWh (10 modules).

¹ Depending on the maximum charge/discharge power of the inverter used.
² Short-term peak power for 3 seconds.
³ The specified height may include the required battery base for floor installation.

General Technical Data of the Growatt AXE Series

The Growatt AXE series is particularly distinguished by its high performance and remote maintenance capability. Even from afar, diagnostics, monitoring, and software updates can be performed, minimizing operational interruptions and reducing maintenance costs. The Growatt AXE batteries intelligently regulate their charge and discharge current, maximizing the lifespan of your entire system.

Moreover, the Growatt AXE series is designed to operate safely even under demanding conditions, thanks to its soft-start function and cobalt-free LiFePO₄ chemistry. A key factor here is thermal stability, which makes LiFePO₄ one of the safest battery technologies on the market.

By combining your Growatt AXE storage solution with a suitable PV system or other energy sources, you can drastically increase your self-consumption of self-generated energy and reduce your electricity costs in the long term. At the same time, you become more independent from fluctuating electricity prices and contribute to environmental protection through the efficient use of renewable energies.

In short: The Growatt AXE series is your ideal choice if you are looking for a versatile, safe, and expandable energy storage system. Whether you want to start small and expand later or need a large storage capacity right away – Growatt AXE adapts flexibly to your needs and offers state-of-the-art technology as well as comprehensive monitoring and protection functions.
