Growatt Arc

The Growatt ARK low-voltage storage system is flexible and expandable due to its modular design. A battery tower can be built with a minimum of 1 and a maximum of 10 ARK high-voltage batteries. A connection cable set for commissioning with a compatible inverter is included in the delivery. The battery base is also available as an option for floor installation.

The Growatt low-voltage battery system includes:

• Growatt ARK 2.5L-A1 low-voltage battery LifePO4 2.56 kWh (3-10x depending on selection)
• Growatt cable set for ARK 2.5L-A1 LV
• Optional: Battery base for floor installation
• Compatible inverters: SPA and SPH single-phase inverters

The Growatt ARK 2.5L low-voltage battery (MPN ARK-2.5L-A1) offers maximum safety through cobalt-free LiFePO4 batteries. The modular, stackable design allows for flexible use in various scenarios and is easy to install. The battery, equipped with an integrated BMS, provides a long lifespan and excellent performance under high loads. A soft start is employed to prevent overvoltage in the system. The ARK low-voltage storage systems are only compatible with the single-phase SPH inverter series.
