Reliable and failure-free quality inverters from Asia

Inverters are the electronic and operational heart of every PV system. High quality, reliable inverters are needed to ensure safe investment returns.

However, as inverters are assembled in a largely manual production process and made of many different and quality-sensitive components, they come with significant risk of defects and performance failures.

The Asian inverter manufacturing industry in particular is dominated by fierce pricing battles. As a result, component quality and assembly workmanship of solar inverters can vary greatly.

Conducting thorough and professional inverter quality testing before shipment is critical to the success of PV projects.
