{"product_id":"20a-pwm-solar-charge-controller-12-24v","title":"20A PWM Solar Charge Controller (12\/24V)","description":"\u003cp\u003eUse this for a real solar bank — a panel charging a 12V or 24V lead-acid battery at up to 20A, with load control and auto voltage detection. Commonly used for off-grid 12V systems, small installations and battery banks. Not suitable as a bigger CN3791: this is a different class of part, PWM rather than MPPT and built for lead-acid, so on a lithium node it is the wrong chemistry and on a shaded panel it harvests less than MPPT would. Key specs: 20A, 12\/24V auto, PWM, lead-acid profile. Alternative: the CN3791 MPPT module for lithium sensor nodes, which is what most project-scale solar actually needs.\u003c\/p\u003e","brand":"Compoden","offers":[{"title":"Default Title","offer_id":53793483587949,"sku":"CDN-3140","price":439.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/3997\/5533\/files\/20a-pwm-solar-charge-controller-1224v-3128359.png?v=1791034927","url":"https:\/\/compoden.com\/products\/20a-pwm-solar-charge-controller-12-24v","provider":"Compoden","version":"1.0","type":"link"}
