Enwitec switching device 1.0 for 3 x SMA Sunny Island - 3-phase

The switching device has been prepared for the installation of an energy meter / Home Manager 2.0.

In the event of a power failure, a standby power system safely disconnects the connected PV system and load distribution from the public power grid and simultaneously provides the customer with a standby power supply.

Due to the new "Battery backup distribution" system from enwitec, which is ready for connection and pre-tested, installers no longer have to build the switching device themselves, which is time-consuming and cost-intensive, and no longer have to assume their own warranty. So far, enwitec's "Switching device for standby power/battery backup distribution" (in short, "BBD") is the only product recommended in the SMA planning guide for use in the "Flexible storage system". The "BBD" for the SMA "Flexible storage system" uses only components approved by SMA, thus forming the basis for maximum reliability of supply.

The standard version with a throughput power of 35KW allows the feeding of three SMA "Sunny Island" battery inverters, whereby the grid separation is always 3-phase and all-pole. Furthermore, enwitec develops and produces customer-specific variants with higher throughput power and various other requirements.
