Use the SMA America String Sizing Utility program to determine the size and configuration of your system. (Please read the disclaimer before using the sizing tool, and do not hesitate to contact the knowledgeable staff at The Alternative Energy Store with any questions you may have!)

Optimal Efficiency

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 sinewave 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 heatsinks 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.

With the optional modem, you can monitor and record the performance of your Sunny Boy inverter via a PC.

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 sinewave shape current and a minimized harmonic distortion. The sequential control system ensures an automatic operation without losses in standby mode.

Integrated Reserves

The large heatsink ensures a continuous operation with nominal power even in surroundings with high ambient temperatures.

Integrated Communication

The monitoring and the sequential control system are enhanced by the possibility to send and receive data and commands to and from a central monitoring device. This feature allows the Sunny Boy to be a standalone device or single components of large PV-plants.

Specifications

Cautions

Because of danger to life and property that improper installation of these systems can cause, you must have your system and its components selected, designed and installed by an appropriately certified electrician. Please note, having the system installed without a licensed electrician will also void the warranty.

The California Energy Commission’s Emerging Renewables Buy-Down Program offers cash rebates on eligible renewable energy electric-generating systems. You can get a rebate of up to $3,000 per kilowatt, or 50 percent off your system purchase price (whichever is less), making it more affordable to generate your own electricity using renewable energy. All types of electricity customers are eligible: residential, commercial, agricultural and industrial. Program participants can buy their electricity from any electric service provider, but their proposed site for the renewable energy system must be within the electric utility service area of: Pacific Gas and Electric, San Diego Gas & Electric, Southern California Edison, or Bear Valley Electric Company. The participant must also remain connected to the utility grid. For more information on the California Emerging Renewables Buy-Down Program, check the CEC’s web site at http://www.energy.ca.gov/greengrid/index.html, or call toll free at (800) 555-7794 (in California) or (916) 654-4058 (outside California).

California isn't the only state to provide incentives for people to purchase grid intertie systems or renewable energy systems period.
