PrimeVOLT inverters won the “Taiwan Excellent PV” award

The Taiwan Excellent PV award held by the Bureau of Energy has entered the ninth year this year, and this year, inverters were included in the competition for the first time; it is the highest quality award for the inverter industry. The major inverter manufacturer, PrimeVOLT, participated in the competition with its three phase inverter series and won the award. The award was presented by the President Ing-Wen Tsai on the 8th, and the General Manager of PrimeVOLT, Chin-Ming Chuang, received the award.

The “2021 Taiwan Excellent PV” award was reviewed according to the national standard (CNS) of the Republic of China (Taiwan); the review contents include the parallel verifications of the inverters, the verification of safety specifications, and the verification of electromagnetic compatibilities, etc. In addition, it was confirmed that the products can adapt to rigorous environments according to the US ASTM B368-09 Copper Accelerated Acetic Acid Salt Spray (CASS) high corrosive test item, and the inverter that is most suitable for the island-type special environment of Taiwan was selected. Most large-scale solar power plants are constructed on salt flat lands in recent years; the high salt environment and the intertidal impacts are rigorous tests to power electronic equipment; general salt spray tests could no longer verify its adaptability.


The PrimeVOLT inverter that won the award is a one-piece aluminum casting box with IP66 dust-proof and waterproof levels, and passed IEC 60068-2-52: 2017 severity 5 salt spray test; it is suitable for use in Taiwan’s island-type humid and rigorous environments. The two sets of MPPT can input independently or in parallel; the built-in DC junction box function has features including PF 0.9 real power output without derating. The design of the appearance also won the Golden Pin Design Award awarded by the Industrial Development Bureau, Ministry of Economic Affairs.


Energy Taiwan will be exhibited at Taipei Nangang Exhibition Center, Hall 2 from 12/8-10, PrimeVOLT will also showcase its latest smart solar photovoltaic inverter series. Chin-Ming Chuang stated that PrimeVOLT inverters won the Taiwan Excellent PV award, which shows its product strengths, and they comply with industry trends. The new inverter products displayed this time are equipped with AFCI (Arc-fault circuit interrupter) arc detection functions that can detect abnormal statuses of the solar power plants automatically, reducing fire and electrical shock hazards and improving safety. The input current is increased to 12. 5A to satisfy high-performance module configurations, and are equipped with nighttime reactive power compensation, meeting the needs of Taipower’s large scale solar power farms. They also support 380V three phase three wire and three phase four wire power systems, which makes wiring more flexible, in which the 22kW inverter is equipped with fan-less natural cooling design, making it more suitable for poultry and livestock house farms.

The new 75kW function upgraded version even leads the industry and is the first to obtain 440/460/480Vac output voltage VPC certificates, suitable for different power environments; it can reduce construction costs of solar power farms, and are more suitable for applications at large-scale power plants, factories and other special power environments.
