Growatt’s ARK high-voltage storage system offers flexible deployment thanks to its modular design and can be expanded as needed. A battery tower can be assembled using a minimum of 3 and a maximum of 10 ARK high-voltage batteries. A BMS control unit and a set of connecting cables are included for commissioning with a compatible inverter. The battery base for floor installation is also available. The A2 version is the successor to the previous ARK 2.5H-A1 and can be easily combined with it.
Important Note —According to Growatt, retroactive expansion is only permitted within the first three months after commissioning and following prior inspection by Growatt. After more than three months of operation, the existing battery capacity should not be expanded further. Please take your future storage needs into account when selecting the set.
The Growatt high-voltage battery system includes:
- ARK 2.5H-A2 high-voltage LiFePO4 battery, 2.56 kWh (3–10 units depending on selection)
- Growatt HVC 60050-C2 ARK BMS control unit for SPH and SPA inverters with base and cable set

ARK 2.5H-A2 High-Voltage Battery
The Growatt ARK 2.5H-A2 high-voltage battery (MPN ARK-2.5H-A2) is a LiFePO4 storage system with high cycle stability and a long service life. Its modular, stackable design allows for flexible use in various scenarios and is easy to install. The battery delivers outstanding performance under heavy loads and, with its IP65 rating, is also suitable for outdoor installation. A soft-start feature is used to prevent overvoltage in the system. The A2 version is the successor to the previous ARK 2.5H-A1 and can also be easily combined with it.
About the ARK 2.5H-A2 battery:
- Modular, stackable battery design
- Cobalt-free lithium iron phosphate (LFP)
- High cycle stability and long service life
- Wall- or floor-mounted installation possible
- Soft start to protect the system from overvoltage
- Automatic wake-up in case of undervoltage
- IP65 protection rating for outdoor installation
- Remote diagnostics and firmware updates
Applications
- For grid-connected and off-grid photovoltaic systems
- Emergency power supply
- Uninterruptible Power Supplies (UPS)
Soft Start for System Protection
The soft-start mechanism is a protective feature used in the Growatt battery to safeguard the system against overvoltage. When the battery is started or powered on, the current is gradually increased to protect the system from damage that could be caused by a sudden voltage spike. This ensures smooth and safe operation of the battery system.
High Cycle Life
Thanks to their extremely high cycle life and the use of LiFePo4 cells, Growatt ARK battery modules are an ideal storage solution for photovoltaic systems. Whether in a grid-connected or off-grid system, Growatt storage offers numerous advantages over conventional lead-acid batteries and other lithium technologies.
