Relay Used in Solar Photovoltaic System

A photovoltaic system is a power generation device that operates in an unattended state. Therefore, it is necessary to select components with reliable performance and long life when designing a solar photovoltaic system. A solid state relay is one switching device worth using in a stand-alone solar photovoltaic system or a wind power system controller.

Solid state relays rely on the electromagnetic and optical properties of semiconductor devices and electronic components to perform their isolation and relay switching functions. Solid-state relays work reliably, with no contacts, no sparks, long life, no noise, no electromagnetic interference, and fast switching speed. They can directly drive large current loads with tiny control signals, and can be used to ensure trouble-free operation of solar photovoltaic system.
