It is designed for small to medium off-grid solar installations where reliable battery charging and load control are required without the complexity of MPPT technology. Suitable for use by installers and system integrators working on caravans, boats, cabins and remote power applications.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e20A charge current compatible with 12V and 24V battery systems, with automatic voltage detection.\u003c\/li\u003e\n  \u003cli\u003ePWM charging algorithm maintains battery health by reducing charge current gradually as the battery approaches full charge.\u003c\/li\u003e\n  \u003cli\u003eLoad output with low-voltage disconnect protects batteries from over-discharge.\u003c\/li\u003e\n  \u003cli\u003eStreet lighting function with programmable on\/off times based on sunset and sunrise detection.\u003c\/li\u003e\n  \u003cli\u003eTemperature compensation adjusts charge voltage to suit ambient conditions, extending battery life.\u003c\/li\u003e\n  \u003cli\u003eCompatible with sealed (AGM and gel), flooded and lithium iron phosphate (LiFePO4) battery chemistries.\u003c\/li\u003e\n  \u003cli\u003eVictronConnect compatible via optional VE.Direct Bluetooth Smart dongle, enabling wireless monitoring and configuration.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.3 kg, suitable for panel or wall mounting.\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 during the bulk charge phase, then switching the connection on and off rapidly to maintain the target voltage. This approach is straightforward and cost-effective for systems where the panel voltage is closely matched to the battery voltage. The PWM-Pro builds on the standard PWM design with additional programmability, including adjustable charge algorithms and a dedicated load output with configurable disconnect thresholds.\u003c\/p\u003e\n\n\u003cp\u003eThe street lighting function is particularly useful for remote or off-grid lighting installations. The controller can be programmed to switch the load on at sunset and off after a set number of hours, or to dim the load mid-night, reducing energy consumption without manual intervention. These settings are configured via the VictronConnect app when used with the optional VE.Direct Bluetooth Smart dongle.\u003c\/p\u003e\n\n\u003cp\u003eThe controller automatically detects 12V or 24V battery voltage on first connection, removing the need for manual voltage selection. Temperature compensation is built in, adjusting the charge voltage set points based on the measured temperature to avoid overcharging in warm conditions and undercharging in cold ones.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: SCC010020110\u003c\/li\u003e\n  \u003cli\u003eCharge current: 20A\u003c\/li\u003e\n  \u003cli\u003eSystem voltage: 12V \/ 24V (auto-detect)\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.3 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076025382\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCaravans and motorhomes with roof-mounted solar panels and leisure battery banks.\u003c\/li\u003e\n  \u003cli\u003eNarrowboats and sailing vessels requiring reliable battery maintenance from solar.\u003c\/li\u003e\n  \u003cli\u003eOff-grid cabins and garden buildings with modest solar arrays.\u003c\/li\u003e\n  \u003cli\u003eRemote street lighting and security lighting installations.\u003c\/li\u003e\n  \u003cli\u003eAgricultural and rural telemetry or monitoring equipment powered by solar.\u003c\/li\u003e\n  \u003cli\u003eSmall backup power systems for sheds, outbuildings or gate automation.\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-Pro Charge Controller 12\/24V-20A\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eInstallation should be carried out by a competent electrician or qualified solar installer. Ensure the solar panel open-circuit voltage does not exceed the controller's maximum input voltage rating. Connect the battery before connecting the solar panel, and disconnect in reverse order. The load output is intended for DC loads only. For LiFePO4 battery installations, confirm the correct charge profile is selected via VictronConnect before commissioning. This controller is not suitable for grid-connected systems and does not require G98 or G99 compliance.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59866752549198,"sku":"SCC010020110","price":34.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_SCC010020110_-_BlueSolar_PWM-Pro_Charge_Controller_12-24V-20A_1d335523-c053-425c-9bd6-2090d8289560.webp?v=1781202475","url":"https:\/\/voltaconsolar.com\/products\/victron-bluesolar-pwm-pro-charge-controller-12-24v-20a","provider":"VoltaconSolar","version":"1.0","type":"link"}
