With the Growatt battery retrofit kit (MPN: 024894), you can easily expand your existing solar system. Depending on your selection, the kit includes 3 to 10 stackable ARK 2.5H-A1 high-voltage batteries featuring modern and safe LiFePO4 technology and a nominal voltage of 51.2V per battery. The matching control unit (HVC 60050-C2 BMS) and the battery base for stable placement are also included. Additionally, you receive a 3-phase SPH 8000TL3 BH-UP hybrid inverter that works optimally with the batteries. The matching connection cable set ensures that the battery tower can be connected directly to the inverter—for quick and easy installation.
Installation Note: For this non-plug-and-play device or component, connection and installation must only be performed by a qualified electrician. Please follow the user manual!

Growatt ARK 2.5H-A1 High-Voltage Battery
The Growatt ARK 2.5H-A1 high-voltage battery (MPN ARK-2.5H-A1) is a LiFePO4 storage unit with high cycle stability and a long service life. The modular, stackable design allows for flexible application in various scenarios and is easy to install. The battery delivers outstanding performance under high loads and, with its IP65 protection, is also suitable for outdoor installation. Soft start is used to prevent overvoltage in the system.
About the ARK 2.5H-A1 battery:
- Modular, stackable battery design
- Cobalt-free lithium iron phosphate (LFP)
- High cycle stability and long service life
- Wall or floor 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
- Battery base and battery connection kit included in the retrofit kit
The ARK Battery System
Thanks to its modular design, the ARK system is flexible and can be expanded as needed. A battery tower can be constructed with a minimum of 2 and up to 10 storage modules; multiple towers can also be installed within a single system. For operation, each tower requires a BMS control unit as well as a connection cable set to the corresponding inverter. For ground installation, an additional battery base is required per tower. ARK high-voltage storage units are compatible with the MIN and MOD-XH, as well as the three-phase SPH and SPA inverters. Depending on the inverter series, a different control unit, a different connection cable set, and a different starting number of batteries are required. The ARK-XH system starts with 2 batteries, while the ARK-HV system starts with 3.
