A Solar DC Isolator Switch is a safety device used to disconnect the direct current (DC) power between photovoltaic (PV) solar panels and the inverter for maintenance, emergency shutdown, and system protection.
A Solar DC Isolator Switch is a manually operated switch designed specifically for high-voltage DC circuits in photovoltaic (PV) systems. It enables safe isolation of the solar array from the inverter during installation, inspection, maintenance, or emergency situations.
Unlike standard AC switches, DC isolators are engineered to safely interrupt direct current without sustaining electrical arcing. They are typically installed near the solar inverter, combiner box, or rooftop PV array and are available in single-pole, double-pole, and four-pole configurations.
Solar DC isolator switches comply with international electrical safety standards and are suitable for residential, commercial, and utility-scale solar installations.
