Varta Element Backup 12/S5 with 13kWh
This grid-connected complete AC system includes 2 battery modules, each with 6.5kWh and thus has a total capacity of 13kWh.
It has an integrated 3-phase battery inverter and offers an emergency power function for selective consumers, which can be implemented using the VARTA emergency power box.
In the event of a power failure, the energy storage device automatically switches to emergency power mode.
In addition, the VARTA element also offers black start capability.
Thanks to practical plug & play technology, the complete system can be installed quickly and easily in any home.
It enables direct communication with different PV inverters without additional hardware.
If required, the storage capacity can be expanded at any time by connecting up to five VARTA energy storage devices with the VARTA Link or the VARTA pulse neo.
The Varta Element Backup series offers 3 capacity sizes that can be expanded at any time: ELEMENT BACKUP 6 with 6.5 kWh
ELEMENT BACKUP 12 with 13kWh
ELEMENT BACKUP 18 with 19.5kWh
Made in Germany
As a traditional German company, Varta offers independence from the market.
They innovate their own products and technology.
Unfortunately, the market is characterized again and again by spontaneous and mostly unannounced price fluctuations and delivery bottlenecks to Germany.
That can't happen at Varta.
