SMA Test Center: The World in a Lab [Video]
More is expected of them than of others: SMA solar inverters must work perfectly for many years. No matter in which country, in which climate, or to which power network they are connected.
That is why our experts at the SMA test center simulate the entire life of an inverter in fast motion. Their tools: high technology and extraordinary methods. They do exactly what a normal customer never would: putting inverters in the oven. Freezing them. Strapping them into a jolting machine.
SMA inverters are used in over 100 countries – from Death Valley to the South Pole. Nearly every operating site has different environmental and climatic conditions. Additionally, the world’s widely varying power grids and grid codes also have to be taken into consideration as well as the electromagnetic compatibility (EMC).
Certified by UL
Thanks to our outstanding equipment, we are one of only a handful of manufacturers to be allowed to perform the inverter approval tests ourselves for the strict American-based Underwriters Laboratories (UL).
Every one of our experts helps to continue to improve the engineering and quality of the inverters – and of the solar industry in general.
Does SMA test for sound power or sound pressure? For example when the SMA Tripower is rated at 51 dB (A) is that unit power or pressure?
we test sound power acoording to EN ISO 9614-2 and sound pressure according to EN ISO 3744. The Sunny Tripower is rated at 51 dB (A). That means the sound pressure.
