Using a companion sensor panel, it measures sun intensity as a percentage of full sunlight (0-100%, where 100% = 1,000 W\/m²) and triggers a relay at a user-selected threshold.\u003c\/p\u003e\n\u003cp\u003ePerfect for automating solar-powered pumps, the SP-SSR ensures your pump only runs when there's sufficient solar energy to operate it properly - protecting the pump from running in marginal conditions and eliminating the need for manual switching. It's also useful for automating any compact DC load that should track sunlight availability.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolar Insolation Measurement\u003c\/strong\u003e - Measures sunlight intensity from 0-100% (0-1,000 W\/m²) for precise, condition-based automation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUser-Selectable Threshold\u003c\/strong\u003e - Set your own trigger point - the relay switches at your chosen sunlight intensity level.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Device Switching\u003c\/strong\u003e - Turns pumps or other compact loads on\/off automatically based on real-time solar conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtects Pump Equipment\u003c\/strong\u003e - Prevents pumps from operating in insufficient sunlight - reducing wear and improving efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelay + Sensor Included\u003c\/strong\u003e - Complete system with relay controller and accompanying sensor panel for immediate installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile Automation\u003c\/strong\u003e - Works with solar pumps, fans, lights, or any compact DC load that benefits from sunlight-tracking control.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SunPumps","offers":[{"title":"Default Title","offer_id":56296427552934,"sku":"SP-SSR","price":385.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0731\/6344\/0294\/files\/PVA30M1_ef177264-fd3a-44e9-b6c7-5219cb2f8962.jpg?v=1773630314","url":"https:\/\/gridfreesupply.com\/products\/sunpumps-sunswitch-sp-ssr-solar-insolation-meter-and-relay-control-system","provider":"Grid Free Supply","version":"1.0","type":"link"}
