Germany-based Varta has released its first all-in-one battery energy storage system (BESS).
The Varta.hybrid.wall solution integrates an inverter, battery storage and energy management into one system configuration. This approach allows installers to configure flexible, scalable packages for a range of system sizes and performance classes.
All components are “Made in Europe” and are technically compatible, the company said.
The solution combines the Varta.wall DC high-voltage storage system with the new Varta.hybrid three-phase inverter, which delivers up to 10 kW of power and features four MPP trackers.
Varta said the system is suitable for both new installations and retrofits of existing PV systems, and can be deployed as an AC or DC coupled solution. The available storage capacity ranges from 4.5 kWh to 20 kWh and can be expanded depending on customer needs. The modular design also supports larger installations via cascading.
Varta.hybrid.wall allows the system to provide three-phase backup power from the storage unit. In the event of a failure, the external Varta.backup switch automatically disconnects the home network from the public electricity grid.
The optional energy management system Varta.iq is manufacturer independent and compatible with up to 700 systems, allowing the integration of all household energy components. Features include dynamic electricity price optimization, bi-directional charging and cascade control.
Varta added that installation times have been reduced through the use of plug-in components and pre-assembled connections. Commissioning is carried out through the Varta.install app, while system monitoring and management is handled through the company’s online portal.
