13 Connecting Sunny Boy Inverters
The following section provides information for connecting and configuring the Sunny
Boy inverter in stand-alone grid systems. You can use the following products with a
Sunny Island 3324/4248:
• 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 6000/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
• Hydro-Boy inverters (for feeding in from fuel cell systems)
13.1 Sunny Boy Wiring
1. Connect the Sunny Boy inverter to the grid in accordance with the Sunny Boy
installation manual.
2. Wire the AC sub-distribution unit to the AC output terminals of the Sunny Island
3324/4248.
3. Set the Sunny Island 3324/4248 to use Sunny Boy inverters by setting the "40-
8 SunnyBoys" parameter to "YES".
4. You must also set some parameters in the Sunny Boy to suit a stand-alone grid
so that it works properly together with the Sunny Island 3324/4248. The
required values for these settings are described in the following section 13.2
"Setting Sunny Boy Parameters" (Page 118).
Ensure that the entire connection area is free of voltage before
installing the Sunny Boy inverter. Please pay attention to section 3
"Safety Instructions" (S. 19).
When using Sunny Boy inverters together with the Sunny Island 3324/4248,
plan to use batteries with a minimum capacity of 100 Ah per 1,000 W installed
PV power.
For a PV generator with an installed capacity of 5 kWp, combined with two
Sunny Boy inverters (2,500 W each), you need a battery capacity of at least
500 Ah.
