It is designed for straightforward off-grid applications where simplicity and low cost are the priority. Automatic voltage detection selects between 12V and 24V operation without manual configuration.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e20A charge current rating, compatible with 12V and 24V battery systems with automatic voltage detection.\u003c\/li\u003e\n  \u003cli\u003ePWM (Pulse Width Modulation) charge algorithm reduces battery stress and extends cycle life compared to unregulated charging.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.15 kg, suitable for small panels and space-constrained installations.\u003c\/li\u003e\n  \u003cli\u003eLED indicator provides basic charge status feedback without requiring a separate display or monitor.\u003c\/li\u003e\n  \u003cli\u003eLoad output with low-voltage disconnect protects the battery from deep discharge.\u003c\/li\u003e\n  \u003cli\u003eReverse polarity protection on the solar input reduces the risk of damage from wiring errors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003ePWM charge controllers work by connecting the solar panel directly to the battery and pulsing the connection on and off to regulate charge current. This approach is well-suited to smaller systems where the panel voltage is closely matched to the battery voltage. The BlueSolar PWM-Light is the simplified variant in Victron's PWM range, omitting advanced monitoring features in favour of a lower cost and smaller footprint.\u003c\/p\u003e\n\n\u003cp\u003eThe 20A rating supports solar arrays up to approximately 260W on a 12V system or 520W on a 24V system, making it appropriate for small cabins, caravans, boats, garden buildings and similar low-demand off-grid setups. The load output allows direct connection of 12V or 24V DC loads, with automatic low-voltage disconnect to prevent the battery from being discharged below a safe threshold.\u003c\/p\u003e\n\n\u003cp\u003eThis controller does not include Bluetooth, VE.Direct communication or a display. For installations requiring remote monitoring or integration with a Victron system, the BlueSolar PWM-Pro or MPPT range should be considered instead.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: SCC010020020\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076025351\u003c\/li\u003e\n  \u003cli\u003eCharge current: 20A\u003c\/li\u003e\n  \u003cli\u003eSystem voltage: 12V \/ 24V (automatic detection)\u003c\/li\u003e\n  \u003cli\u003eCharge algorithm: PWM\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.15 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSmall off-grid cabins and garden buildings with modest DC loads.\u003c\/li\u003e\n  \u003cli\u003eCaravans and motorhomes with a single solar panel and a leisure battery.\u003c\/li\u003e\n  \u003cli\u003eNarrowboats and small leisure craft with basic 12V or 24V DC systems.\u003c\/li\u003e\n  \u003cli\u003eRemote monitoring stations, gate openers and similar low-power installations.\u003c\/li\u003e\n  \u003cli\u003eAgricultural and rural applications where a simple, low-maintenance charger is required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Victron BlueSolar PWM-Light Charge Controller 12\/24V-20A (SCC010020020)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eInstall in a dry, ventilated location away from direct sunlight and moisture. Connect the battery terminals before the solar panel terminals, and disconnect in reverse order. Ensure cable sizing is appropriate for the 20A maximum current. A suitably rated fuse should be fitted on the battery positive cable as close to the battery as possible. This controller is not suitable for lithium battery chemistries unless the battery manufacturer confirms compatibility with standard PWM charge profiles. For any installation on a vessel or vehicle, follow the relevant wiring regulations for the application. Qualified installation is recommended for anyone unfamiliar with 12V or 24V DC solar wiring.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":47483509866830,"sku":"SCC010020020","price":17.66,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/victron-bluesolar-pwm-light-charge-controller-1224v-20a-scc010020020-648326.jpg?v=1747940622","url":"https:\/\/voltaconsolar.com\/products\/victron-bluesolar-pwm-light-charge-controller-12-24v-20a","provider":"VoltaconSolar","version":"1.0","type":"link"}
