SMA now has the state of the art "US" series with built-in DC disconnect. The SMA Sunny Boy series is perfect for everything from moderately sized residential systems to large industrial three-phase systems. Now with the introduction of the US series, we are ready to offer more flexibility for many applications.

sma inverter Sunny Boy inverters are housed in a watertight NEMA 3R outdoor enclosure, and can operate in extreme conditions (ambient temperatures of -13ºF to +113ºF). They can even be mounted right on the roof along with the modules.

The Sunny Boy is designed to support PV modules in series, increasing efficiency and eliminating the need for expensive DC distribution systems and cabling. The Sunny Boy inverters increase efficiency further because they run a separate MPP tracking for each single string. Each Sunny Boy inverter is equipped with a separate and autonomous grid monitoring facility that enables the user to hook up the AC output to any point within the electric distribution system of house.

One high voltage series string of solar modules can be connected to each inverter, vastly simplifying design and installation. The result is no mismatching from parallel connections and maximum Power Point Tracking for every series string. System expansion is easy - simply add more inverters and series strings of solar modules. This modular approach results in a cost effective way to build large systems.

Simplified system design and lowest installation costs
No DC distribution necessary
System diagnosis and monitoring via powerline
Extended Operating Temperature Range (-13ºF to +113ºF)
NEMA 3R Weatherproof Case for Outside Installation
Equipped with MC and AC connector

Sunny Boy system diagnosis and control can be transmitted to your PC via wireless or RS-485.

Sunny Boy Advantages

Optimal Efficiency
The Sunny Boy inverter family convinces with a real efficiency of up to 97.1%. The advantages of the string technology such as connection of the modules in series, missing diode arrays, minimized mismatching losses and so on increase the PV system efficiency by another 1 to 3% compared to others. Sunny Boy provides the best available system efficiency.

Surge Voltage Protection
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.

Reliability
Highest reliability and a lifetime of over 20 years were major aspects taken into account during the design of the Sunny Boy string inverters. The newest SMA series of inverters has a 10 year warranty.

Simplest 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 anymore 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 NEMA 3R rated case 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 world-wide usage of the inverter is therefore possible.

Diagnosis And Communication Via Wireless or RS-485
Of course you can communicate with your Sunny Boy. Measurement values and messages are transmitted to a PC via wireless or RS485 cable. You can be continuously informed about the situation of your PV plant. You can even view statistics of your solar system on the Internet!

Utility-tie Inverters

Utility inverters change DC power into AC power to be fed into the utility grid. A power system with this type of inverter uses the utility company as a storage battery.

When the sun is shining, your electricity comes from the PV array, via the inverter. If the PV array is making more power than you are using, the excess is sold to the utility (power company) through an electric meter. If you use more power than the PV array can supply, the utility makes up the difference.

This type of system makes the most sense if you have utility power, because there are no batteries to maintain or replace, but it has a very long payback period and may not be cost-effective at today’s electric rates. The SMA Sunny Boy and Fronius inverters are examples of utility tie inverters.
