Growatt’s new APX HV battery system is composed of an APX 55042-P0-US (hereinafter referred to as Power Module) and multiple APX 5.0P-B1-US battery modules (hereinafter referred to as Battery Module, the maximum number of Battery Module connected in parallel is 6), enables a flexible capacity from 5kWh to 30kWh. The APX HV battery is compatible with Growatt MIN series Grid-tie inverters (3~11.4kW), and the entire system can switch between Grid-tied and Off-grid modes through the Growatt backup box( ATS-US or SYN 200XH-US)
The APX battery system adopts cobalt-free LiFePO4 chemistry and four-level protection by BMS, modular energy optimizer, fuse, and aerosol to ensure its enhanced safety, reliability, and long lifespan. Furthermore, the modular energy optimization ensures the system fully uses every pack's energy, mixes packs of new and old batches, and mixes packs of different capacity, which offer the most flexible system application
The stackable design of the APX HV battery system makes it easier to install with internal plugs, requiring no extra cable connections. So both installation and maintenance were made simple.

FAQ
The Growatt APX is a high-voltage residential energy storage battery system designed for solar self-consumption, backup power, and energy management. It uses modular LiFePO₄ battery technology and supports capacities from 5 kWh to 30 kWh per system.
The APX battery uses cobalt-free LiFePO₄ (Lithium Iron Phosphate) cells, offering high safety, long cycle life, and improved thermal stability compared with many other lithium battery technologies.
The standard APX HV system is expandable from 5 kWh up to 30 kWh by adding battery modules. This allows homeowners to start small and increase capacity as their energy needs grow.
Yes. One of the APX's key advantages is its modular energy optimization technology, which allows the mixing of new and existing battery modules and even modules with different states of charge. This simplifies future system expansion.
Yes. The APX battery features an IP66 protection rating, making it resistant to dust, rain, and harsh environmental conditions. It can be installed indoors or outdoors when local installation requirements are followed.
The APX incorporates multiple layers of protection, including:
- Battery Management System (BMS)
- Modular energy optimizer
- Fuse protection
- Aerosol fire suppression protection
- Soft-start technology to reduce electrical surges
These features enhance both safety and reliability.
The standard APX HV battery is designed to operate in temperatures ranging from -10°C to 50°C. The newer APX Battery 2.0 extends this range further with built-in heating technology for cold-weather performance.
The APX battery is designed to work with compatible Growatt hybrid inverter series, including selected MIN-XH, MOD-XH, and MID-XH models, depending on regional product availability and system design.
Yes. When paired with a compatible Growatt hybrid inverter and backup interface, the APX battery can supply stored energy to essential household loads during utility outages. The actual backup capability depends on inverter configuration and local installation requirements.
The APX features module-level energy optimization, allowing each battery module to operate independently. Benefits include:
- Better utilization of stored energy
- Easier system expansion
- Support for mixing old and new battery modules
- Improved overall system flexibility and performance
This architecture is one of the APX platform's most distinctive features.
No. The APX battery is designed as a low-maintenance energy storage solution. Routine monitoring through Growatt's monitoring platform and periodic inspections by qualified installers are generally sufficient to ensure optimal performance.
