Quality assurance plays an important role in our company, since this forms the basis for the reliability and cost-effectiveness of our solutions. In order to guarantee consistently high standards, we subject our products to extensive endurance tests that extend far beyond existing standards - even at the development stage. For example, Fronius inverters must withstand considerably tougher conditions in the laboratory than they would encounter in real life. Only when a device has emerged unscathed after being subjected to the effects of extreme temperatures, moisture, ice, salt, dust and dirt do they go into series production - to then be delivered to our customers.
