WARNING!
All electrical installations must be done in accordance with all local electrical codes and
with the National Electrical Code (NEC), ANSI/NFPA 70. For installation in Canada the
installations must be done in accordance with applicable Canadian standards.
WARNING!
Use #10 AWG to # 6 AWG, 90 °C (194 °F), copper wire for all DC wiring connections
to the Sunny Boy. Voltage drop and other considerations may dictate that larger size wires
be used. Use only solid or stranded wire but not fine stranded wire.
WARNING!
The DC disconnect for the inverter must have a minimum rating of 600 V DC and 36 A
continuous. The SMA DC disconnect is shipped with four 15 A, 600 V DC fuses (one for
each string). The maximum fuse rating for the four SMA DC disconnect fuses is 20 A, 600 V
DC (one for each string). For fuse sizing please refer to NEC 690.9.
Use the online SMA string size calculator at www.sma-america.com to determine the
correct string configuration. To navigate to the string size calculator, click on the shortcut
on the home page.
Series fusing may be required depending on the type of PV module used in the system. See
NEC 690.9.
