Description
SMA Backup 3P Kit
The SMA Backup 3P Kit offers a reliable backup power solution for households with a three-phase grid connection. Thanks to intelligent phase coupling, it supplies single-phase loads on all three phases, ensuring a stable power supply even in the event of a grid failure. The automatic switchover function ensures a seamless transition between grid and backup power operation. Thanks to its simple integration into the existing meter cabinet, flexible installation via DIN-rail mounting and low self-consumption (<1 W), the system is extremely efficient. Compatible with Sunny Boy Smart Energy Inverters – ideal for a smart, uninterrupted energy supply.
