Inverter relays are specialized relays used in power inverter systems, where direct current (DC) is converted into alternating current (AC). Their main role is to control the switching, protection, and isolation of electrical circuits within the inverter.

These relays help manage functions such as connecting and disconnecting loads, selecting power sources, and protecting the system from faults like overcurrent or short circuits. Because inverter systems often handle high voltages and currents, inverter relays are designed to be highly reliable, fast-switching, and resistant to heat and electrical stress.

Inverter relays are commonly found in solar power systems, uninterruptible power supplies (UPS), electric vehicles, and industrial inverters. In simple terms, inverter relays ensure safe and efficient operation of inverter systems by controlling power flow and providing electrical protection.
