Fronius has been working in the field of photovoltaics since 1992 and over the years has become one of the pioneers in the field of renewable energy. Our customersbenefit from long-lasting, high-performance solar electronics systems that meet the highest quality standards.

In our Research & Development facilities, Fronius devices are thoroughly tested during stringenttrials in order to endure a minimum duration of 20 years in service even in harsh conditions. All products undergo additional and unique robustness tests, as durability test (fluctuations in temperaturefrom -20 to +100 °C), salt spray and moisture test, sand test and many other.


Sandstorm Test

Dirt and dust particles must not be able to enter solar electronics, as they can cause short circuits and other defects. Fronius has tested the Fronius ECO (25-27) and the SYMO (10-20) at the TÜV InterCert S.r.l.-Group of TÜV Saarland concerning the working behaviour during sandstorm. The result: Even in the worst case scenario the samples withstand the test without blocking for 60 minutes, then the fan jams due to sand infiltration. After removing the sand the inverter starts working again. The protection class IP 66 / IP 65 guarantees that there will be no dust within the powerelectronic parts.


Feedback from our clients about outdoor installations in the harsh conditions of the Middle East Region:

Eng. Gorkem Soyumer from Dubai- based Enerwhere Sustainable Energy about Solar Carpark System at My City Centre Al Barsha Mall, 123.5 kWp, commissionedon 01.10.2016:

Inverters have not reported any failure due to harsh weather conditions. 4 FroniusECO 27 and 1 Fronius SYMO 20 are installed outdoors shaded by the solar car parkstructure avoiding direct radiation. The temperature losses are minimal. We haverecorded 54 °C by the temperature sensors reporting through the remote monitoringsystem. Every quarter we perform a cleaning of the inverters from inside. We aresatisfied with the outdoor performance.

Dr. Michael Koch from Premier Composite Technologies about in-house 80 kWprooftop Solar PV System in Dubai Investment Park with 5 Fronius SYMO 10 and1 Fronius SYMO 20, commissioned in January 2016:

We didn’t face any problem with Fronius inverter because of sand and dust. We cleanthe inverters from inside every six months. The highest module temperature spottedwas above 70 degrees.

Feedback from the General Manager of Edama Solar Energy Co., Ltd., based in Jordanian Amman, Mr. Raed Rabadi:

We had a chance to look inside the first Fronius inverter that was installed in Jordan,located in the west of Amman, commissioned in November 2014. When we were changingthe filter in 2017, there was almost no sand accumulated around the fan itself.Overall outdoor inverters are performing well, when proper sizing is taken into consideration.We did not face any failure case due to sand stuck in the inverter.
