At SMA, every individual component and finished device are subjected to intensive qualification and test procedures. In a unique test center equipped with seven test chambers, one test area and twelve system and development stations, state-of-the-art measurement techniques and test procedures covering a variety of different areas are used.
With more than 35 years of experience and a total installed capacity of over 55 gigawatts worldwide, SMA has unique experience in the development, design and engineering of inverters and complete solutions for every requirement and need.
SMA has developed the intelligent cooling system OptiCool, which allows SMA inverters to be installed outdoors in all climatic conditions. For 1,500 V central inverters, SMA uses a stack topology with a 38 percent design reserve to ensure maximum reliability.
In SMA’s production facilities, we produce inverters and solutions in accordance with future-oriented standards and using state-of-the-art production methods. Our long-term documentation of individual production steps ensures that the high quality of the individual components and the complete devices remains transparent at all times.
At SMA, the stacks are tested before they are installed – in the same position in which they will later be installed in the inverter. This allows us to derive information about the component’s subsequent function in advance.
Test conditions:
Every finished Sunny Central inverter is intensively tested to ensure full and fault-free functionality. Tests meet all standards and certifications
Two inverters alternate between inverter and rectifier operation – at full power. The temperature behavior is assessed and information derived regarding their later behavior in the field.
As one of the top 5 operations and maintenance providers, SMA offers a range of services to ensure the long-term efficiency and profitability of large PV power plants. This ensures optimal and reliable system performance with maximum yields for over 25 years and beyond.
