System Topology

The Sunny Home Manager must be installed behind the meter and the input fuse of the grid operator and in front of the first distributor in the house. SMA recommends using the Sunny Home Manager for measuring at the point of interconnection. As a bidirectional device, the Sunny Home Manager measures both the grid-supplied power and the grid feed-in at the point of interconnection.

The Sunny Home Manager receives the measured data for PV generation, grid feed-in, and grid-supplied power via the integrated measuring device directly from the connected SMA inverters or a separate, optionally connected SMA Energy Meter.
