PV Inverter Testing

Safe, high quality and compliant photovoltaic inverters with our testing and certification services

Inverters and converters are the most important part of conventional and renewable power systems, such as solar, fuel cell, electrical energy storage systems, wind power plants and gas turbine power systems. As competition in the renewable energy industry grows, companies strive to ensure their photovoltaic inverters and converters are safe, functional and compliant with relevant standards. Choosing to partner with us is the first step in meeting these goals. We offer the widest range of market access services for PV inverters helping you to access all PV installation markets based on your focus requirement.

We test and certify your inverters and converters with AC output, either grid connected or stand-alone operation, according to local and international specifications and standards to ensure their safety, quality and compliance. Successful test results can lead to certification and the right to use our internationally recognized test mark. Besides this our experts provide component evaluation services for certain unlisted or non-approved components used within inverters or converters.

Our experts enable you to access reliable, respected testing services for your photovoltaic inverters wherever your business is located. We provide more than 35 years of experience in the PV industry. Our PV network with eight fully-owned PV inverter laboratories spread over all major production countries around the world while being at the pulse of new product trends is making us experts of local requirements. It enables us to support you through the whole lifecycle of your PV inverter products.

Give us a call today and let us inform you on how you can benefit from our services and decades of expertise on PV inverter testing.
