16 Sunny Boy

The following section provides information for connecting and configuring the Sunny
Boy inverter in stand-alone grid systems. At the time this documentation was printed, the
following products could be used with a Sunny Island 5048:
• Sunny Boy inverters (for feeding in from PV systems):
SB 700 / SB 1100 / SB 1100LV / SB 1700 / SB 2500 / SB 2800i / SB 3000
/ SB 3300 / SB 3800 / SMC 5000 / SMC 5000A / SMC 6000 / SMC 6000A
/ SMC 6000TL / SMC 7000TL / SMC 8000TL
• Windy Boy inverters (for feeding in from wind turbines or hydropower systems):
WB 1100 / WB 1700 / WB 2500 / WB 2800i / WB 3000 / WB 3300 /
WB 3800 / WB 6000
• All Hydro-Boy inverters (for feeding in from fuel cell systems)

16.1 Connection to the Stand-alone Grid

Ensure that the entire connection area of the Sunny Island 5048 is free of
voltage before installing the Sunny Boy inverter. Please pay attention to
section 3 "Safety Instructions" (Page 23).
• Connect the Sunny Boy inverter to the grid in accordance with the Sunny Boy
installation guide.
• Wire the AC sub-distribution unit to the AC1 terminals of the Sunny Island 5048.
The Sunny Island 5048 no longer requires a special setting when used with Sunny
Boy inverters (this is not the case with the Sunny Island 3324/4248).
• You must set the corresponding parameters in the Sunny Boy to suit a stand-alone
grid so that it works properly together with the Sunny Island 5048. The required
values for these settings are described in the next section.
For a PV generator with an installed capacity of 5 kWp, combined with two Sunny
Boy inverters (2500 W each), you need a battery capacity of at least 500 Ah.
