Advantages
The Sunny
Boy inverter family convinces with a real efficiency of more than 93 %.The
advantages of the string technology such as connection of the modules in series,
missing diode arrays, minimized mismatching losses and so on – even increase the
PV-system efficiency by another 1 to 3 % compared with other PV-systems. The
Sunny Boy Family provides the best available system efficiency.
Surge Voltage Protection
The Sunny
Boy inverters are equipped with thermally monitored varistors on the DC side –a
male function of these is indicated with a LED and can be supervised with a
remote monitoring system.
Maximum Safety
Personnel
safety and hardware reliability are major issues of the products developed by
SMA. The Sunny Boy Family safety strategy includes electric separation,
isolation monitoring, surge voltage protection and of course the CE declaration.
A MSD (Mains monitoring with allocated Switching Devices, German: ENS) in
accordance with VDE 0126 is naturally a standard feature of the Sunny Boy
inverters.
Get Ready for the Future!
The new
module oriented design, the perfect sine wave shaped output current, dual
processor technology and an integrated one-phase sensitive grid monitoring
according to the VDEW regulations define new standards resulting in a new era of
supplementary grid feeding with PV-plants.
Reliability
Highest
reliability and a lifetime of over 20 years were major aspects taken into
account during the design of he Sunny Boy string inverters.
Overload Capability
The power
electronics and the heat sinks of the Sunny Boys are well dimensioned in order
to allow he Sunny Boy to operate continuously even in surroundings with high
ambient temperatures. This means: You can rely on the Sunny Boy string inverter.
Flexible
The Sunny
Boy String inverters each process the power from 6 to 24 modules, depending on
the inverter type. This leaves you enough freedom for the individual design of
your PV-plant.
Simple Installation
The
modules are switched to a string and then connected to the Sunny Boy. DC
distribution cases and connection boxes are no longer necessary any more
resulting in drastically reduced installation costs.
Connect it Anywhere
The Sunny
Boy string inverter can be connected to any available part of the AC
distribution system of the house, e.g. in an attic or a similar room.
Mount it Anywhere
The
stainless steel case with protection class IP65 and the wide temperature range
allow the Sunny Boy to be mounted nearly anywhere. The Sunny Boy can be
installed directly on the rack of the PV-modules, on the roof or on the wall of
your house A worldwide usage of the inverter is therefore possible.
Diagnosis and
Communication via Powerline –no extra cables!
Of course
you can communicate with your Sunny Boy. Measurement values and messages are
transmitted to a PC on the existing powerline with a socket modem. The Windows
based program Sunny Data visualizes he system performance and controls the
inverters. You are continuously informed about the situation of your PV-plan .
Best Priced System
The Sunny
Boy system technology allows a most reasonably priced plant with simple
installation and optimal efficiency.
Experience for the Future
SMA has
always been a pioneer in developing and producing inverters for photovoltaic
applications. More than 30 MW of total installed inverter power from SMA have
defined standards in this technology. This experience was the basis for he
development of the Sunny Boy string inverter.
Modern Power Electronics
The power
section of the Sunny Boy features a simple and robust design with highest
efficiency and continuous reliability. The DC voltage from the PV modules is
processed by a MOSFET bridge switched with 16 kHz and is passed on o an AC
circuit. This voltage is then directly fed to the AC grid with a transformer.
Digital Monitoring
Digital
SCS The control of he current fed to the grid is managed by a one-chip computer
which guarantees an perfect sine wave shape current and a minimized harmonic
distortion. The sequential control system ensures an automatic operation without
losses in standby mode.
Integrated Reserves
The large
heat sink ensures a continuous operation with nominal power even in surroundings
with high ambient temperatures.
A
very wide DC input voltage range of 250 – 600
V DC and the ability to connect
up to three parallel strings, allows the system designer to use nearly any
module configuration. Experience in Europe has shown that the economically ideal
system design is with a PV array size of 2,700 to 3,400 Wp at standard test
conditions.
The
inverter’s operating data including PV voltage, output power, and daily power
production can be viewed using the optional “Sunny Display” – a two line LCD
integrated in the lid. In larger PV-systems, data from multiple inverters can be
stored and viewed using the SWR-COM plug in modem and a PC or via the stand
alone “Sunny Boy Control” data logging devices. Other possible communications
options include plug in RS232 and RS485 modules.
You can
communicate with your Sunny Boy. Measurement values and messages are transmitted
to a PC on the existing power line with a socket modem. The Windows based
program Sunny Data visualizes the system performance and controls the inverters.
You are continuously informed about the situation of your PV-plant.
The
string inverter technology, developed by SMA, has revolutionized PV applications
in Europe and made the SMA inverters the favorite of European customers. SMA is
the European market leader of inverters with a power range of up to 5 kW. String
Technology utilizes a small number of PV-modules connected in series to create a
“string“. A small number of strings are connected to individual inverters that
feed the electricity of the string directly to the grid. The string inverter
concept minimizes the complexity of the DC wiring system and reduces overall
system costs. The energy produced by the PV system is combined on the AC side,
making system design very simple. Using multiple string inverters, larger PV
plants can be easily created with minimal design effort.
