Scope of application
The ELR2 series DC isolation switch adopts a plastic shell and is suitable for residential or commercial photovoltaic systems with a power output of 1-20KW. It is placed between the photovoltaic module and the inverter. The arc time is less than 8ms, making the solar system safer. Our products are made from the best quality components. The maximum voltage can reach 1200VDC. Leading in safety among similar products.
