relay Attention:Solar equipment is a mixed load, we do not recommend using solid state relays.If you want to try, you need to buy a solid state relay with 10 times the current.At the same time, if the solid state relay does not work normally on the solar equipment, we do not provide return service.

PS:OurHeatSinkinclude2screws forinstallheatsink andapackofthermalcompound isappliedtothebottomoftheSSR NOTICE: The inside of the solid state relay is a semiconductor. A semiconductor switch is a non physical contact switch. if use a multimeter diode or resistor to test ,it always show a high impedance state, multimeter light red . According to the conventional detection methods of solid state relays: a load is required to test the switching state. Using an incandescent lamp as a dummy load is an obvious way to test continuity.
