Growatt ARK HV 12.8 kWh A2

The Growatt ARK HV 12.8 kWh A2 battery storage system is the latest generation of high-voltage battery storage for Growatt hybrid inverters of the SPH series and Growatt battery inverters of the SPA series. Each system consists of 2 to 10 ARK HV 2.56 storage modules, connected in series and stacked into a tower, providing a usable total capacity ranging from 4.6 kWh to 23.04 kWh.

In the version presented here – the Growatt ARK HV 12.8 kWh A2 – 5 ARK HV storage modules, each with 2.56 kWh, are used to achieve a total capacity of 12.8 kWh. The storage systems can be expanded with additional battery modules for up to three months after commissioning. We therefore generally recommend selecting a larger battery storage system, as this one can also be charged via AC power, which can be particularly attractive for winter use in combination with a dynamic electricity tariff. If you know your highest daily electricity consumption, multiply it by 1.1 to determine the ideal storage size to cover a 24-hour period in winter.

The use of cobalt-free lithium iron phosphate batteries offers clear advantages in terms of safety and longevity. These batteries are extremely safe and offer improved charging and discharging efficiency.

We recommend floor installation. From a storage size of 17.92 kWh (7 battery modules), we recommend splitting the system into two towers.
