Impressive 1 MWp roof-top system in hot and humid temperatures

2018/12/10 / Vietnam, Bai Dai

Keeping a cool head - with Active Cooling Technology

Humidity and hot temperatures are a fact of life in the Khanh Hoa region along Vietnam’s eastern seaboard. The choice of inverter is therefore extremely important, as the heat will have a direct impact on the performance of the device. Fortunately, the Palma Vietnam Investment Joint Stock Company opted to install a Fronius inverter in their 1 MWp system.

 

Fronius inverters are equipped with Active Cooling Technology – an intelligent cooling system with temperature-controlled fans that keep the inside of the unit cool. This ensures that even high ambient temperatures do not have a negative impact on the service life of the inverter. In addition, this technology has a positive effect on the derating behavior – and therefore yields – of our inverters.

 

The customer is also delighted with the Fronius Solar.web online tool: “With Fronius Solar.web, we can easily monitor and check the PV system both from a PC and the app.”

Did you know?

A temperature increase of 10°C halves the service life of the power electronics. So we’ve taken action: Fronius inverters are equipped with Active Cooling Technology, which cools the sensitive power electronics and extends the service life of the inverter.


The system is split into one roof-top installation at the clubhouse and 91 roof-top installations at individual villas
