The country approvals of the components must be checked.
This storage package combines the 3-phase Smart Energy hybrid inverters from SMA with the VARTA.wall high-voltage storage system. The hybrids, which are available in 4 power classes, boast a full range of features from overvoltage protection to interfaces. Experience has shown that the visualization in the SMA Sunny Portal is at the highest level. The VARTA.wall is probably the flattest storage system on the market. In a stacked design with up to 4 modules on top of each other and only 100 mm depth, it fits behind almost any door.
