The ark high-voltage storage system from Growatt is flexible due to its modular concept and can be expanded as needed. A battery tower can be set up with a minimum of 2 to a maximum of 10 ark high-voltage batteries. For commissioning with a compatible inverter, a bms control unit and a connection cable set are included. For ground installation, the battery base is also available as an option.
The Growatt high voltage battery system includes:
- ark 2.5h-a1 high voltage battery LiFePO4 2.56kWh (2-10x depending on selection)
- bdc 95045-a1 bms control unit
- Connection cable set ark battery to inverter
- Optional: Battery base ground installation
Compatible inverters
Please note that at least three ARK high-voltage batteries are required to connect the Growatt MOD-XH inverter.
ark 2.5h-a1 high voltage battery
Growatt ark 2.5h-a1 high voltage battery (mpn ark-2.5h-a1) is a LiFePO4 storage battery with high cycle stability and long lifetime. The modular, stackable design allows flexible application for different scenarios and is easy to install. The battery offers excellent performance under heavy load and is also suitable for outdoor installation with its ip65 protection. To avoid overvoltages in the system, the soft start is used.
About the ark 2.5h-a1 battery:
- Modular, stackable battery concept
- 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 overvoltages
- Automatic wake-up in case of undervoltage
- Protection class ip65 for outdoor installation
- Remote diagnostics and firmware update
Areas of application
- For grid-connected as well as stand-alone photovoltaic systems
- Emergency power supply
- Uninterruptible power supplies (usv / UPS)
Softstart to protect the system
The soft start mechanism is a protective function used on the Growatt battery to protect the system from overvoltages. When the battery is started or turned on, the power supply 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
Growatt ark battery modules are an ideal storage solution for photovoltaic systems due to their extremely high cycle life and the use of LiFePo4 cells. Regardless of whether it is a grid-tied or off-grid system, Growatt storage offers numerous advantages over traditional lead-acid batteries and other lithium technologies.

bms control unit
The Growatt bdc 95045-a1 bms acts as a central monitoring and control unit within the ark high-voltage battery system and supports communication with Growatt min and mod xh inverters. It allows the connection of up to 10 battery modules with an individual capacity of 2.56 kWh. These modules can be connected in series to form a battery tower that has a total capacity of up to 25.64 kWh. Storage towers can also be connected together, requiring one bms per tower.
About the bdc 95045-a1 bms
- Compatible with Growatt min-xh and mod-xh inverters
- Modular, stackable battery design
- Monitoring and control
bms control parameters
Control parameters include state of charge (soc), line voltage, current, cell voltage, cell temperature and PCBA temperature measurement. By precisely monitoring these parameters, the bms ensures optimal battery performance and longevity.
Flexible expansion
Growatt's ark battery system offers great flexibility through its expandable configuration options, which range from 2.56 kWh to 25.6 kWh. Installation and expansion of the system is simple and straightforward due to its modular design and use of cables. Another innovation of the ark system is that, unlike other battery systems, no battery cabinet is required. Only a battery base is required for a stable stand.

Connection cable set to inverter
The Growatt battery cable set is needed to connect Growatt ark2.5h-a1 batteries to min- or mod-xh series inverters.
- 2x 2m power cable (plus/minus)
- 2m communication cable
- 2m ground wire
ark battery base
The Growatt ark battery base is suitable for ground installation of Growatt ark battery modules and provides a secure stand for the battery tower. The Growatt ark system is modular, meaning that multiple batteries can be combined, with the Growatt Base serving as the foundation. Up to 10 storage modules, as well as the associated bms, can be stacked on one base.
