Communication Options
Sunny Boy inverters are available with different communication options depending upon
your needs. The SB3800U series allows for both internal and external metering options
to be used simultaneously. These options may also be installed in the field by qualified
personnel.
PC Applications and Monitoring
Sunny Boy operating data may be transmitted to, and stored in, a remote system or PC
by one of the following methods:
• RS-232: Data from one inverter is sent via an RS-232 cable to a remote control unit or PC.
Maximum length of cable is 50’ (15 m).
• RS-485: Data from up to 50 inverters is sent via RS-485 cable to a remote control unit or
to a PC. Maximum length of cable is 4000’ (1200 m). An RS-485/232 converter may be
necessary for communication with a PC.
• Wireless: Data from up to 4 inverters is sent to the Sunny Beam by means of an antenna
installed in the SB3800U. Communication distance is dependent upon obstructions and
the radio environment.
