SMA Inverters
The most widely used Inverters for grid connection in Europe.

Advanced technology and highest reliability have made the string Inverters from SMA the most widely used Inverters for grid connection in Europe.

• Optimal Efficiency
The Sunny Boy inverter family convinces with a real efficiency of more than 94%. 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.

• Overload Capability
The power electronics and the heat sinks of the Sunny Boys are well dimensioned in order to allow the Sunny Boy to operate continuously even in surroundings with high ambient temperatures. This means: You can rely on the Sunny Boy string inverter.

• 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 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.

• 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 world-wide usage of the inverter is therefore possible.

• Diagnosis And Communication Via Power line - No Extra Cables
Of course 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.
