relayAttention: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.STEP1:ChooseacorrectcontrolModeAA-ACControlACDA-DCControlACDD-DCControlDCVA-ControlandAdjustSTEP2:ChooseacorrecttypeCurrentofEquipment/Ratio=CurrentofSSRPS:TheRatiodependonthekindofyourloadingequipment.Resistiveload:70%,Inductiveload:20%,Capacitiveload:10%.STEP3:Chooseasuitableheatsink.DuringtheuseageofSSR,itwillgiveoutalotofheat,soinordertoextendthelifeofyourSSR,pleaseinstallaheatsink,alsoifthecurrentisover60A,thecoolingfanalsorequired.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.
