Operation Sunny Beam Manual
30
The Percentages: Displays the success rate of the communication. Ideally this number would
remain at 100% indicating that all requests for data were completed. If this number was 50%,
it would mean that half of the time the Sunny Beam is unable to complete a request for data
with the Sunny Boy. If the number is 0%, it means that the Sunny Beam is unable to
communicate with any of the inverters and needs to be moved closer.
The “transmit arrow” in the center of the screen: This arrow illuminates whenever the Sunny
Beam transmits a request for data.
The Bar Graphs: The bar graphs display the relative field strength of the signal being received
from the Sunny Boys. In other words, it graphically displays how well the radio signal from the
Sunny Boys is being received. Ideally, these bar graphs should light across the entire scale
indicating full strength. This makes it easy to determine if all of the inverters being monitored
are being received equally.
To leave the Diagnostics screen, press the knob.
Communication
The Communication menu is used when setting up the Sunny Beam for use with a PC running
Sunny Data Control.
SBeam: When connected to Sunny Data Control, only the information on the Sunny Beam will
be displayed. (Power output, daily yield, total yield)
Plant: Allows data from the Sunny Boy inverters to be displayed on a PC via Sunny Data
Control. Selecting this mode will allow the information in the inverters and the information in
the Sunny Beam to be displayed.
NOTE: No matter which setting is selected, only data for the entire plant is
recorded. Individual inverter data is displayed, but not recorded.
Transmitting Power
Firmware versions 2.16 and earlier, have an item in the Setup menu called Transmitting Power.
There are two possible settings: norm and test. The power levels for both the inverter(s) and the
Sunny Beam should be set to test. The transmit power for the inverter(s) is set by a command
from the Sunny Beam. To change the power levels, the Sunny Beam will need to be within radio
range of the inverter(s) and the inverter(s) will need to be operating at the time. Be sure to save
the changes when prompted to do so after exiting the menu.
