The string inverters are compact, lightweight and quiet in operation (up to 31.6 decibels), as they do not have their own fan. These features make the inverters particularly suitable for installation on residential and office buildings. Outdoor installations are possible due to the IP66 protection class and a temperature range of minus 25 to 50 degrees Celsius. The inverters have two MPP trackers and an input voltage range of 200 to 1,000 volts DC.

To prevent operational failures, they are equipped with important features: dielectric strength up to 1100 VDC, arc protection and reverse polarity protection, which especially improves installer safety. A built-in anti-PID function prevents power degradation in crystalline solar cells. In addition, replaceable AC and DC surge arresters type 2 are integrated, string fuses are therefore not required.
