SMA Sunny Central solar inverters

Extreme environments make extreme demands on solar technologies. SMA’s range of Sunny Central inverters has been developed to withstand the negative effects of weathering.

Temperature extremes are coupled with significantly higher inverter loads, meaning the output can rapidly increase. Using innovations such as the company’s OptiCool system for high temperatures, the inverters have been tested to endure temperatures ranging from -40 to 90°C and humidity between 10 and 95%, in tests lasting up to 1000 h.

Desert locations have sand particles that can penetrate the smallest openings and slits, risking the operation and life expectancy of the entire PV installation. The system’s encapsulated design securely protects the units and their electronic components from dust.

The inverters include a number of features which make them durable and robust at high altitudes. The dimensioning and peak voltage features of the Sunny Central CP units are designed to compensate for the low air pressure, temperatures and dielectric strength of air. All control voltage circuits are hardened for altitudes up to 4000 m and inverters are designed with a modified DC window.

With 100% nominal power up to 50°C, the inverters provide high power outputs. Furthermore, the CP and HE series can deliver 10% more power in continuous operation at ambient temperatures of up to 25°C, with efficiencies of 98.5%.

Whether for outdoor devices or inverters for enclosed spaces, both series offer high performance. High-tech functionalities such as comprehensive grid management and intelligent power management make them advantageous for plant operators. But the greatest advantage is the output. With 10% overload capability at low temperatures, more modules can be connected.
