Addtime:2022,10,26

One of the essential components of PV system is the Inverter isolator switches. They work to prevent the Inverter from draining power when the AC system is not being used. So, they help to avoid expensive repairs. In this article, we will discuss Inverter isolator basics to help you determine on your own whether you need one or not.

What are Inverter isolator switches?

They are systems or devices that isolate a specific circuit for maintenance and help prevent any currents from passing through. The isolator, or main isolator switch, is typically comprised of one or two sets of electrical contacts mounted in a series. The isolator’s line side gets connected to the power supply located on the outside of the building.

Isolation devices prevent potential currents from flowing inside circuits that are not being maintained. It does this by cutting all electricity off that goes to them.

Inverter isolators have been designed to prevent the repeated tripping of home safety switches when faulty PV systems. The isolator disconnects the power supply as soon as it detects any malfunction or unusual electrical fault. That can save the homeowner money on expenses involved in repairing the AC unit and help to prevent other parts of the house from getting damaged.

That means there is no chance for faults to occur, such as ground fault interruptions that can pose safety risks, including injuries caused by electrocution and death from electric shock when using an appliance during a thunderstorm near a water source.
