Figure 1: Design of a PV plant with Sunny Boy 240-US and Multigate XT
The Multigate XT contains between 1 to 4 Sunny Multigates, each of which are a
communication unit that forms the connection point of the PV plant with a maximum
of twelve micro inverters to the utility grid. The Multigate XT is connected between the
Sunny Boy 240-US micro inverter and the utility grid to feed the alternating current
converted by the inverters collectively into the utility grid. The Multigate XT is designed
for split-phase operation only. The Multigate XT must be operated in conjunction with
SMA Sunny Boy 240-US.
