For a long time, high power generation cost has been one of the main reasons restricting the development of PV industry. How to reduce the power generation cost of PV system and improve power generation efficiency has become the core issue of PV industry. 1500V means lower system cost. PV modules, DC switches and other parts, especially inverters, play a vital role. The research on 1500V PV system led by inverter manufacturers has increasingly become a technical hotspot in the industry. Therefore, it is a trend to develop 1500V related PV products.
Compared with 1000V system, the voltage is increased to 1500V, which puts forward higher technical requirements for performance, withstand voltage and reliability of circuit breakers, disconnectors and other components. Aswich Electric has always been committed to providing complete PV protection products. In view of this new industry development trend, Aswich Electric has launched PV DC Moulded Case Circuit Breaker (1500V 630A) to help users reduce investment costs, simplify project construction and improve equipment reliability.
