PV DC Isolator Switch | 1500V, IP66, Arc-Quenched

An Australian renewable energy company sought a reliable switching solution for a 100MW solar farm in Queensland. The harsh environment, with high temperatures and dust, demanded robust and weather-resistant equipment. We supplied 500 of our PV DC isolator switches, rated at 1500V DC and 400A, equipped with IP66 enclosures. These switches provided safe isolation for each string combiner box, enabling efficient maintenance. Over two years of operation, the project reported zero switch-related failures, achieving a 99.95% system availability. The client particularly appreciated the clear visible break and padlockable handle, which enhanced worker safety and compliance with Australian standards. This case highlights how our switches deliver reliability and safety under extreme conditions.

A German installer specializing in commercial rooftop solar systems faced challenges with limited space and the need for compact yet safe disconnection. They selected our PV DC isolator switches, which are among the slimmest in the market, allowing for easy integration into existing electrical cabinets. With a breaking capacity of 600V DC and a current rating of 32A, these switches ensured safe isolation for each solar array. The project, completed in 2023, involved 120 switches across 15 commercial buildings. Feedback highlighted the ease of installation and the clear ON/OFF status indication, which reduced commissioning time by 15%. This case demonstrates our ability to provide space-saving solutions without compromising safety, meeting the stringent requirements of the German photovoltaic market.

A US-based solar installer needed a cost-effective yet reliable PV DC isolator switch for residential rooftop systems. They aimed to meet the National Electrical Code (NEC) requirements for rapid shutdown. Our PV DC isolators, designed with a compact structure and high breaking capacity, were integrated into the DC combiner boxes. Over 1,000 units were installed in California and Arizona over a year. The switches performed flawlessly, with no reported failures. The installer praised our product's compliance with UL 98 standards and its competitive pricing, which helped them win more contracts in the competitive residential market. This case emphasizes how our switches provide code-compliant safety at an accessible price point.
