It provides up to 20A of charge current and includes a built-in LCD display and USB output port, making it suited to small off-grid installations, caravans, boats and remote power setups where straightforward solar charging and on-board monitoring are required.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDual battery output (DUO) allows simultaneous charging of two separate battery banks from a single solar input.\u003c\/li\u003e\n  \u003cli\u003eCompatible with 12V and 24V battery systems, with automatic voltage detection.\u003c\/li\u003e\n  \u003cli\u003e20A maximum charge current supports a range of small to mid-size solar panel configurations.\u003c\/li\u003e\n  \u003cli\u003eBuilt-in LCD display shows real-time system data including battery voltage, charge current and charge state.\u003c\/li\u003e\n  \u003cli\u003eIntegrated USB port provides a 5V output for charging phones, tablets or other USB-powered devices directly from the solar system.\u003c\/li\u003e\n  \u003cli\u003ePWM (Pulse Width Modulation) charge algorithm extends battery life by reducing stress during the absorption and float phases.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.377kg, suitable for space-constrained installations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003ePWM charge controllers regulate the current flowing from the solar panel to the battery by switching the connection on and off at high frequency. As the battery approaches full charge, the controller reduces the average current delivered, preventing overcharge without the complexity of MPPT tracking circuitry. This makes PWM controllers a cost-effective choice for smaller systems where the panel voltage is closely matched to the battery voltage.\u003c\/p\u003e\n\n\u003cp\u003eThe DUO variant adds a second battery output, which is particularly useful on boats or campervans where a starter battery and a leisure battery need to be maintained separately. The primary bank charges first; once it reaches a set threshold, the controller diverts charge to the secondary bank. This prevents the secondary bank from drawing down the primary.\u003c\/p\u003e\n\n\u003cp\u003eThe LCD display gives installers and end users immediate visibility of system status without needing a separate monitor or app. The USB port is a practical addition for mobile and remote installations where mains power is unavailable.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"border: 2px solid #f87c24; border-collapse: collapse; width: 100%;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f87c24; color: #ffffff;\"\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSKU\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSCC010020060\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSystem Voltage\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e12V \/ 24V (auto-detect)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eCharge Current (max)\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e20A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eCharge Algorithm\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003ePWM (Pulse Width Modulation)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eOutputs\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eDual battery output (DUO)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eDisplay\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eBuilt-in LCD\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eUSB Output\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e5V USB port included\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eWeight\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e0.377 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eGTIN\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e8719076046219\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCampervans and motorhomes requiring separate starter and leisure battery charging from a single solar panel.\u003c\/li\u003e\n  \u003cli\u003eBoats and narrowboats with dual battery bank setups.\u003c\/li\u003e\n  \u003cli\u003eSmall off-grid cabins, sheds or outbuildings with 12V or 24V battery systems.\u003c\/li\u003e\n  \u003cli\u003eRemote monitoring stations or security installations with low power requirements.\u003c\/li\u003e\n  \u003cli\u003ePortable solar setups where USB device charging is needed alongside battery charging.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Victron BlueSolar PWM DUO-LCD\u0026amp;USB 12\/24V-20A charge controller\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThis controller is intended for 12V and 24V off-grid battery systems only and is not suitable for grid-connected installations. Ensure the solar panel open-circuit voltage does not exceed the controller's rated input. For dual battery bank wiring, follow Victron's published wiring guidance to ensure correct sequencing of charge between primary and secondary banks. Installation should be carried out by a competent person familiar with low-voltage DC electrical systems. Fuse both the battery and solar connections close to the source as per standard DC wiring practice.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":47483517534542,"sku":"SCC010020060","price":36.64,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/victron-bluesolar-pwm-duo-lcdusb-1224v-20a-scc010020060-790612.jpg?v=1747940654","url":"https:\/\/voltaconsolar.com\/products\/victron-bluesolar-pwm-duo-lcd-usb-12-24v-20a","provider":"VoltaconSolar","version":"1.0","type":"link"}
