4.1 Multigate XT
The Multigate XT is an outdoor rated enclosure containing between 1 and 4 Sunny
Multigates, associated terminal blocks for inputs from each string of Sunny Boy micro
inverters, associated terminal blocks for outputs of each Sunny Multigate to the AC
Grid connection point, and associated hardware for Speedwire (related to Ethernet)
connection for monitoring system performance over the internet.
Each Sunny Multigate installed in the Multigate XT is 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 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.
