Options
The Sunny Island 4248U allows you to connect a variety of options to it for remote metering,
load control and controlling optional equipment such as a generator.
The Sunny Island 4248U supports all of the SMA Control series of metering and data
acquisition devices through the use of the optional “Communication Piggy Back” unit. This
enables the inverter to communicate in either the RS232 or RS485 formats.
A variety of communication options are available to connect multiple Sunny Island 4248U's
together or combine other SMA products on the same communication bus.
For customers desiring remote access to the Sunny Island 4248U, various modems and
Ethernet options are also available. With an (optional) RS232 Piggy-Back local access to the
Sunny Island 4248U is a simple wire connection between a PC and the Sunny Island 4248U
(The Sunny Data application and a MS Windows PC are necessary to communicate with the
Sunny Island 4248U from local or remote locations. Sunny Data is available free-of-charge on
the SMA-America web site: www.sma-america.com).
The Sunny Island 4248U also supports the automatic operation of 2-wire start generators as
a standard feature. The optional GenMan unit enables the inverter to operate multiple-wire-
start generators. The GenMan option is available from your local distributor/dealer. Manual-
start type generators may also be used.
The terminal blocks are grouped according to function. This helps keep the wires for the
different options together and makes for a more organized wiring compartment.
