It suits off-grid installations where a clear on-device display and USB charging output are practical requirements. The built-in LCD gives installers and end users direct visibility of system status without needing a separate monitor.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e48V system voltage with a 20A charge current rating, suitable for small to medium off-grid arrays.\u003c\/li\u003e\n  \u003cli\u003eLCD display shows battery voltage, solar input, charge current and charge state directly on the unit.\u003c\/li\u003e\n  \u003cli\u003eIntegrated USB output port allows low-power device charging from the solar system.\u003c\/li\u003e\n  \u003cli\u003ePWM charge algorithm extends battery life by reducing overcharge stress during the float stage.\u003c\/li\u003e\n  \u003cli\u003eCompatible with sealed, gel and flooded lead-acid batteries.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.3 kg, suitable for panel-mounting in enclosures or on DIN rail with an adapter.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003ePWM controllers work by connecting the solar panel directly to the battery once the bulk charge threshold is reached, then rapidly switching the connection on and off to maintain the target voltage. This approach is straightforward and cost-effective for smaller systems where the panel voltage is closely matched to the battery bank voltage. The 48V rating makes this unit appropriate for larger off-grid battery banks where a higher nominal voltage reduces cable losses.\u003c\/p\u003e\n\n\u003cp\u003eThe LCD on this unit removes the need for a separate battery monitor or app to check basic system status. Charge current, battery voltage and charge stage are all readable at a glance. The USB port is a practical addition for sites where small devices such as phones or radios need charging without a separate inverter. This is not a Bluetooth or VE.Direct connected device, so remote monitoring via the Victron ecosystem is not available on this model.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: SCC040020050\u003c\/li\u003e\n  \u003cli\u003eSystem voltage: 48V\u003c\/li\u003e\n  \u003cli\u003eMaximum charge current: 20A\u003c\/li\u003e\n  \u003cli\u003eDisplay: Built-in LCD\u003c\/li\u003e\n  \u003cli\u003eUSB output: Yes\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.3 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076046240\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 outbuildings with 48V lead-acid battery banks.\u003c\/li\u003e\n  \u003cli\u003eRemote monitoring stations or telecoms enclosures requiring a 48V solar charge source.\u003c\/li\u003e\n  \u003cli\u003eAgricultural or rural installations where a simple, readable charge controller is preferred.\u003c\/li\u003e\n  \u003cli\u003eBackup power systems using 48V flooded or sealed lead-acid batteries.\u003c\/li\u003e\n  \u003cli\u003eEducational or demonstration solar setups where on-device readout is useful.\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-LCD\u0026amp;USB 48V-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 48V nominal battery systems only. Connecting it to a battery bank of a different voltage will damage the unit. Ensure the solar panel open-circuit voltage does not exceed the controller's rated input. Installation should be carried out by a qualified electrician or experienced solar installer. For any grid-connected or larger off-grid systems, consult a professional familiar with current UK wiring regulations.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":60201799582030,"sku":"SCC040020050","price":23.78,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_SCC040020050_-_BlueSolar_PWM-LCD_USB_48V-20A.webp?v=1784819065","url":"https:\/\/voltaconsolar.com\/products\/victron-bluesolar-pwm-48v-20a-lcd-usb","provider":"VoltaconSolar","version":"1.0","type":"link"}
