Sunny Boy Communication
In operating
a wind or solar system, there is a necessity for trouble-free operation.
There are many options for system control and monitoring. From the
wireless Sunny Beam, and the proven Sunny Control, to
Internet-based worldwide system monitoring with the Sunny WebBox
and Sunny Portal with large displays for public areas, there are
technical solutions to meet any requirement.
Sunny Communications Data Sheet

Communication Methods |
|
Wireless |
No
cables required, convenient data transmission for distances up
to 30m, and for up to 4 inverters. |
| Powerline |
No
additional cables required. Distance up to 1000m and up to 50
inverters. Not suitable where mains interference may be present. |
|
RS232 |
Low-cost cable link for a single inverter. Distance up to 12m. |
|
RS485 |
Reliable transmission for complete, continuous data recording.
Distance up to 1200m, up to 50 inverters. |
|
Ethernet |
Standard for computer networks. Can be extended as much as
desired. Simple connection to the Internet. |
|
USB |
Distance up to 5m for one inverter. |
Communication
methods need to be chosen between inverters and monitoring device (eg.
Sunny Control) and between this device and external access or
display. Often distances involved or number of devices will determine
options.
Sunny Boy Displays
Operating state monitoring, fault monitoring and
data acquisition are carried out within the Sunny Boy inverter with
the following variables measured:
Sunny Boy and Windy Boy inverters are fitted with
displays
in their lids to show essential information and in addition all values
can be accessed centrally via a PC or a Sunny Boy Control unit
using a choice of communication methods and data-interfaces.
Piggy-back boards for fitting to inverters to allow external display
& communication using wireless, powerline, RS232 or RS485 as
appropriate.
Sunny Communication between Sunny Boy and PC
Plug-in modem allows PC to communicate via mains
wiring to inverters fitted with powerline modems. Versions are available
for both RS232 or USB ports on the PC. In three phase systems a phase
coupler is required to allow powerline communication across the phases.
Direct connection to a single inverter fitted with an
RS232 piggyback board is possible but for multiple inverters, each needs
to be fitted with RS485 piggyback boards connected together then an
RS485/RS232 or RS485/USB converter allows connection to a PC port.
Sunny Data Windows
software can then be used on a PC to enable easy and graphical
representation of data allowing comparison between array strings;
display of spot values; or PV-plant management. (Available for
download from
www.sma.de)
Service cables allow
easy and reliable communication between a single inverter and a laptop
PC to enable installer checking or setting of inverter parameters.
Particularly useful for installation of Windy Boy inverters to
allow inverters to be matched to the turbine.
Sunny
Beam Wireless Display
 This
allows wireless communication with up to four Sunny Boy inverters
fitted with Sunny Beam transmitters. In this case each inverter
is fitted with Sunny Beam transmitter piggy back interfaces.
Radio signal range of up to 30m inside buildings and up to 100m outside. Powered by
integral solar cell and rechargeable battery, graphic display shows
daily yield (kWh) current power (W) and total yield (kWh).
The Sunny Beam stores
one months data which can be downloaded to a PC via USB.

Sunny Boy Accessories
MultiContact Adaptor Cables
Sunny Boy &
windy Boy inverters have polarised MultiContact connectors for
connection of the DC input. These adaptor cables are useful for use
between the inverter and DC isolators from the PV array or wind turbine
controller.
SWR-MC is for use with Sunny Boy & Windy Boy
inverters up to 3800W. SMC-MC for use with SMC 5000A/6000A or
WB-5000A/6000A.
Grounding Kits a llow DC grounding
of Sunny Boy inverters for use with certain PV modules. Positive
grounding for back-contact modules (eg. Sunpower); and negative
grounding for some thin-film modules.
