Growatt Battery Storage ARK HV 20.4 kWh

The Growatt battery storage ARK HV 20.4 kWh is a modular high-voltage battery for use within a storage system for photovoltaic or solar installations. Each system consists of 3 to 10 ARK HV 2.56 storage modules that can be connected in series to form a tower with a total usable capacity of 6.9 to 23.04 kilowatt hours (kWh).

In the version of the ARK HV 20.4 kWh battery storage system - presented here - 8 ARK HV storage modules with 2.56 kWh each are used, so that a total usable capacity of 18.43 kWh is achieved. Further battery modules can be added to the storage systems at any time.

An advantage of the use of cobalt-free lithium-iron-phosphate batteries is their safety and service life. The batteries are extremely safe and promise better charging and discharging efficiency.

The battery storage units can be easily mounted on the wall or placed on the floor using the stand included in the set.
