The Growatt ARK 2.5H-A2 high-voltage battery (MPN ARK-2.5H-A2) is a LiFePO4 storage battery with high cycle stability and a long service life. The modular, stackable concept enables flexible application for different scenarios and is easy to install. The battery offers excellent performance under high loads and is also suitable for outdoor installation with its IP65 protection. The soft start is used to avoid 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 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 overvoltage

Automatic wake-up in the event of undervoltage

Protection class IP65 for outdoor installation

Remote diagnostics and firmware update

The ARK battery system - version A1 and A2 can be combined

The modular concept means that the ARK system can be used flexibly and expanded as required. A battery tower can be set up with at least 2 and up to 10 storage modules, and several towers can also be installed in one system. You can easily combine the new A2 with the old A1 version. One BMS control element and a connection cable set to the corresponding inverter are required per tower for operation. One battery base per tower is also required for ground installation.

The ARK high-voltage storage systems 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 batteries.

Application areas

For grid-connected and stand-alone photovoltaic systems

Emergency power supply

Uninterruptible power supplies (UPS)

Flexibly expand

The ARK battery system from Growatt offers a high degree of flexibility thanks to its expandable configuration options, which range from 5.12 kWh to 25.6 kWh. Installation and expansion of the system is simple and straightforward thanks to the modular design and the 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.

Soft start to protect the system

The soft start mechanism is a protective function that is used with the Growatt battery to protect the system from overvoltage. When the battery is started or switched 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

The Growatt ARK battery modules are an ideal storage solution for photovoltaic systems due to their extremely long cycle life and the use of LiFePo4 cells. Regardless of whether it is a grid-connected or stand-alone system, the Growatt storage system offers numerous advantages compared to conventional lead batteries and other lithium technologies.
