Pay attention to all safety relevant information in the technical documentation.
Overview
This document details the communication between an SMA Sunny Boy Control remote interface device and an
Adaptive Microsystems / BetaBrite LED display.
Other Adaptive Microsystems displays may be used with the Sunny Boy Control Family, however, this document
will use the BetaBrite for all examples. Proper configuration of this display requires configuration using an
external program such as ActiveX or AlphaNET. This document does not attempt to describe all of the functions
available in the Adaptive Microsystems displays. It will only describe a basic configuration.
Application
Many PV-plant owners wish to display the performance of their PV-system in a public forum. LED lobby displays
allow for basic performance information to be clearly displayed at a reasonable cost. Display models vary in
complexity and performance options to suit the owners requirements.
In order to provide this service to the PV community, SMA has developed software drivers for the Sunny Boy
Control Family specific to a number of common display companies found throughout the world. These companies
include Datalite, HvG, Siebert, EnergieCom, and Adaptive Microsystems. This document is specific to configuring
communication with the Adaptive Microsystems BetaBrite display.

Necessary Equipment
The following equipment is necessary to connect a BetaBrite display with a Sunny Boy Control (SBC):
•
Sunny Boy Control Light, Sunny Boy Control or Sunny Boy Control Plus
•
Communication cable, DB9 female to RJ12, available at SMA-America in 5, 10, 15 and 20 meter lengths
•
BetaBrite LED display, configured for communication with the SBC
Preprogrammed displays are available at SMA America. Call for further details.

RS232 jack
BetaBrite sign

The following additional equipment is necessary to program the BetaBrite displays:
•
Gender changer adapter, male-to-male
•
Programming software (ActiveX or AlphaNet)
Choosing a Sunny Boy Control
All of the Sunny Boy Control remote interface devices are equipped with drivers for communication to the
Adaptive Microsystems display devices. You must use a SBC device to interface with the display. The displays
are not capable of direct communication with the Sunny Boy inverters. The SBC Light and SBC require use of the
COM2:PC port for connection to the BetaBrite display. The SBC Plus may be configured for either COM2:PC or
COM3:AUX.
Cable Requirements
If you choose to construct a communication cable, please refer to the following:

RS232 is the communication protocol used between the Adaptive Microsystems / BetaBrite sign and the SBC
device. Therefore, the wire distance should be kept as short as possible. 15 meters is the maximum
recommended cable length, however, longer distances may work.

Programming the BetaBrite LED Display
The following example uses the AlphaNET V2 software package. This program is not available at SMA
America. Contact Adaptive Microsystems for more information. Please refer to the AlphaNET operations manual
for detailed information on programming LED displays.
Using AlphaNET to program the BetaBrite display.
The AlphaNET software consists of two primary programs for configuring the Adaptive Microsystems displays:
Site Manager:
The Site Manager organizes sign messages in a
directory tree structure. The project name or specific
sign is represented by the root directory, and the subdirectories represent the individual program files which
will run sequentially on the display. Each individual
program file maintains configurations (color, graphics,
speed, scrolling, etc.) specific to that program. Each
program may only contain one configuration type, i. e.
you cannot have two different colors formats in one
program file.
The following steps will walk you through a basic message that will display the daily kW-Hr production of a
Sunny Boy PV-plant.
www.SMA.de
1.
From the Site Manager, select File / New Site.
2.
Enter a Site Name, and select Alpha V2.0
Compatibility. Make sure the Connection Device is
set to the local communication port (typically
Com1 on most computers) used to interface the PC
to the display.
3.
Nothing needs to be done in the Sign Info or
Group Info tabs.

4.
In the Advanced Tab, select Strings “A” – “Z”..
5.
Select OK.
6.
From the Message Editor select File / Select New.
Immediately, save this file. It will be stored as an
MSW file.
7.
From this editor window, enter a text message.
8.
Select File / Simulate to see how the display will
appear on the BetaBrite. When the simulator
appears, you can right-click on the display and
choose Change Display to select the exact model
of display you are programming.
9.
Select the various message formats from the
Modes, Characters and Options pull down menus.
All configuration parameters for the text message
should appear prior to the actual text.
10.
To enter the data that will be read from the SBC,
select Options / String, then enter B, for the first
data placeholder in the SBC. This is equivalent to
Display Channel 01 in the SBC. Subsequent data
channels will follow as C, D, E …up to Z. The A
data byte is reserved for SBC use.
11.
When finished programming, save the file.
12.
From the Site Manager Program, select
Messages / Add and direct the window to the file
that was just saved. The Site Manager will load
the file in under the Directory created in Steps 2-5.
13.
Download the message to the BetaBrite sign by
selecting File / Transmit / Selected Sites. The sign
will immediately start the new program.
14. Subsequent message files may be created and
loaded into the Site Manager. They will run in the
order shown in the Site Manager Message Name
window.

Configuring the Sunny Boy Control String Parameters
The SBC is configured with default parameters in 25 locations. These parameter channels are, by default,
disabled to conserve on the communication buss overhead. To configure the SBC to communicate with the
BetaBrite display, you must first configure the SBC communication port, enable the parameter channels and
configure each channel for the data of interest and display format.
The following instructions will describe configuring the first channel in the
SBC to send the E-today value to the BetaBrite display. The BetaBrite is
connected to the “PC/COM2” in this example.
1.
Turn on the SBC controller.
„Meas. Data
---------------„Diagnosis
„Setup
‰
2.
Enter the Installer parameter. Press ESC, scroll down and select
“Setup” (ENTER), then select Parameter. Enter the User parameter. It is
the numerical sum of the month, day and year. For example March
30, 2002 is 3 + 30 + 2 = 35. With the up and down arrow keys
enter [ID0035_]. The SBC will beep 3 times if the code is correct. If
the code does not work, verify the SBC date setting is correct.

„Ext. Display Š
3.
Select “Interfaces” / ”Ext. Display”.
4.
Scroll once down from Interface. It should display “-deactivated”.
Press ENTER and scroll down unit it reads COM2: PC. Press ENTER,
then ESC. The arrow to the left of the display will return to solid.

6.
Scroll down to “Configure”. This menu contains all 25 Display
Channels. A dot to the left of the Display line indicates that parameter
is active. Press ENTER on Display 01.

7.
On the first line press ENTER to select configure the data that will be
broadcast on channel Display 01. For this example we will select Etoday as seen by the SBC. Select the SC….########## to choose the
Sunny Boy Control with all connected Sunny Boy inverters. Next scroll
down to “E-today” and press ENTER.
[ DISPLAY 01 ]
Dev.:Channel
…SC:E-today
Format……………04.0
8.
Press ESC twice and watch the display. Verify the E-today is shown in
the Channel.
9.
Change the format if desired. Format 04.0 will display 4 digits with
no decimal. Format 06.2 will display 6 digits, two of which will be to
the right of the decimal (i. e. 2425.98).
10.
Press ESC four times until you are prompted ‘Do you want to save the
changes?’. Press ENTER once.
11.
The SBC is now configured to broadcast the daily energy production
value to Com2 for the Adaptive Display devices.
12.
Connect the SBC to the BetaBrite display. The SBC data will be
displayed in the sign’s text message.
