A solar inverter is a crucial component of a solar photovoltaic (PV) system – more commonly known to your everyday user as a solar panel system. Solar inverters are responsible for the task of changing the direct current (DC) into alternating current (AC) through solar energy.
If there is no relay inside the inverter, then there must be an external relay to ensure safety. Even if the solar PV system inverter has a preinstalled isolation switch, the electrical wiring connected to the inverter still carries live and potentially lethal amounts of DC electricity.
However, relays are electrically operated switches that are placed at the output side of an inverter. So, unlike our manually operated switches, a relay uses an electrical signal to control an electromagnet, which in turn connects or disconnects another circuit.

So, unlike our manually operated switches, a relay uses an electrical signal to control an electromagnet, which in turn connects or disconnects another circuit. The way relays and inverters work together is pretty intuitive: If one malfunctions, the other is ready to step in and ensure that everything stays safe.
