Growatt ARK 2.5H-A1 High Voltage Battery (for ARK XH/HV Systems)

Growatt ARK 2.5H-A1 high voltage battery unit is part of the ARK XH and HV Battery Systems. These two storage systems are modular in design and stackable, so one can easily expand the storage capacity. In addition, the quick connectors ensure easy plug & play installation.

This is a lithium-ion battery (LiFePO4) which has some advantages over lead acid and other batteries such as longer life, little to no maintenance, extremely safe, relatively light weight and improved discharge and charging efficiency.

The battery has an IP65 protection level and is suitable for both wall and floor installation. However, a separate base may be required for installation on a floor.

Depending on the ARK Battery System and desired capacity, one stack can support from 2 to 10 battery modules:

✔ Single phase battery system (ARK XH) using Growatt MIN TL-XH inverter: a minimum of 2 and a maximum of 7 batteries can be used in series (5.12kWh – 17.92kWh).

✔ Three phase battery system (ARK HV) using Growatt SPH/SPA BH-UP inverter: a minimum of 3 and a maximum of 10 batteries can be used in series (7.68kWh – 25.6kWh).
