A DC isolator is a device used to electrically isolate different sections of a direct current (DC) electrical system. It is typically used in solar panel installations, battery storage systems, and other DC electrical systems to prevent electrical current from flowing between the isolated sections.

The DC isolator consists of a switch that can be turned on or off to allow or block the flow of electrical current. It is usually mounted on a panel or enclosure and has two inputs and two outputs, with one set of inputs and outputs being used for the isolated section and the other for the rest of the system.

DC isolators are important for safety reasons, as they allow technicians and electricians to work on a section of the system without the risk of electrical shock. They also help to prevent electrical fires and other accidents that can occur when electrical current flows through the wrong parts of the system.
