The roof-mounted system has an output of 76.6 kWp. The main challenge for this project is that the average temperature at the site is over 30 degrees Celsius (80 Fahrenheit). In conventional inverters, these high temperatures can lead to overheating of the electronic parts; an increase of just 10 degrees Celsius can halve the service life of the devices. To avoid this eventuality, the operators in Vietnam opted for three Fronius Eco inverters.
"These inverters have Active Cooling Technology. Fans fitted to the exterior constantly cool the device which extends its service life," said Hans-Georg Einwagner, Area Sales Manager at Fronius Solar Energy.
Even in regions with high ambient temperatures, the inverters deliver their full output power and maximum yields. The inverters may be fitted flat, vertically or horizontally and are therefore suitable for a range of application areas.
The government of Vietnam has set itself the goal of installing PV systems with a total output of 12 GW within the next 12 years.
