It auto-senses 12V or 24V systems, so there's no manual voltage switch to get wrong during setup.\u003c\/p\u003e\u003cp\u003eThe onboard LCD reports charging status, battery voltage, and system health at a glance, and a built-in USB port lets you top up a phone or power bank straight off the solar array. Four-stage PWM charge management (bulk, boost, float, equalisation-style behaviour) helps extend battery life, while dual MOSFET reverse-current protection stops the panel draining the battery after dark. Built-in short-circuit, overload, and reverse-polarity protection add a safety margin for rooftop and off-grid installs.\u003c\/p\u003e\u003cp\u003eUseful for Indian hobbyists and installers running small solar setups for garden lights, cabins, IoT sensor stations, or backup battery banks.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCountry of origin:\u003c\/strong\u003e India\u003c\/p\u003e","brand":"Robocraze","offers":[{"title":"Default Title","offer_id":49831426949377,"sku":"TTD-RC-ANDUSBOUTPUTPORT","price":649.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/1577\/3185\/files\/1_234a015f-55e1-4f9e-90a0-7053cf8fc7af.png?v=1784047794","url":"https:\/\/techdepot.in\/products\/20a-digital-pwm-solar-controller-with-lcd-and-usb-output-port","provider":"Tech Depot India","version":"1.0","type":"link"}
