Growatt ARK HV 25.6 kWh A2 Doppelturm

The Growatt ARK HV 25.6 kWh A2 battery storage system is the latest generation of high-voltage 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, which are connected in series and assembled into a tower with a usable total capacity ranging from 4.6 kWh to 23.04 kWh.

This version – the Growatt ARK HV 25.6 kWh A2 – includes 10 ARK HV storage modules, each with 2.56 kWh, resulting in a total capacity of 25.6 kWh. To ensure greater stability, the system is configured as two connected towers. The storage system can be expanded with additional battery modules within three months of commissioning. For this reason, we generally recommend opting for a larger storage unit, as this system can also be charged via AC — an attractive feature for winter use, especially in combination with a dynamic electricity tariff. To determine the ideal storage size to cover 24 hours in winter, multiply your peak daily electricity usage by 1.1.

The use of cobalt-free lithium iron phosphate (LFP) batteries offers significant advantages in terms of safety and service life. These batteries are extremely safe and provide better charging and discharging efficiency.

We recommend floor installation. For systems with a capacity of 17.92 kWh (7 battery modules) or more, we advise splitting the system into two towers.
