Growatt ARK HV 20.4 kWh A2

The Growatt ARK HV 20.4 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 battery modules connected in series and stacked into a tower, providing a usable total capacity ranging from 4.6 kWh to 23.04 kWh.

The version presented here – the Growatt ARK HV 20.4 kWh A2 – includes 8 ARK HV storage modules, each with 2.56 kWh capacity, resulting in a total capacity of 20.4 kWh. The storage systems can be expanded with additional battery modules up to three months after commissioning. We generally recommend opting for a larger battery storage system, as this model can also be charged via AC. This is particularly beneficial for winter use in combination with a dynamic electricity tariff. To calculate your ideal storage size, take your highest daily energy consumption and multiply it by 1.1 – this ensures 24-hour autonomy during winter.

The use of cobalt-free lithium iron phosphate batteries offers major benefits, particularly in terms of safety and lifespan. These batteries are extremely safe and provide better charge and discharge efficiency.

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