It suits small solar charging setups where one panel array needs to maintain two separate battery banks, such as a starter battery and a house or service battery on a boat.\u003c\/p\u003e\u003cp\u003eThe controller uses PWM charging with programmable bulk, absorption and float stages, and the LCD gives status monitoring and setup access from the unit. Automatic system voltage detection supports 12V and 24V operation for lead-acid battery systems, while LiFePO4 charging is supported for batteries that have an internal BMS.\u003c\/p\u003e\u003cp\u003eTwo 5V USB outputs provide up to 2A combined for charging small USB devices, and the common negative layout helps with integration into many low-voltage DC installations. The enclosure is IP20, so it belongs in a dry, protected location rather than an exposed cockpit, deck locker, or wet engine space.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e12\/24V PWM solar charge controller with a 20A rated charge current.\u003c\/li\u003e\n\u003cli\u003eTwo separate battery outputs for charging a starter battery and a service or house battery from one controller.\u003c\/li\u003e\n\u003cli\u003eProgrammable charge current ratio for adjusting how charging is shared between the two battery outputs.\u003c\/li\u003e\n\u003cli\u003eProgrammable three-stage charging with bulk, absorption, and float stages.\u003c\/li\u003e\n\u003cli\u003eBattery algorithms for AGM, GEL, flooded lead-acid, and LiFePO4 batteries with an internal BMS.\u003c\/li\u003e\n\u003cli\u003eLCD display for system status monitoring and controller setup.\u003c\/li\u003e\n\u003cli\u003eTwo 5V USB ports with up to 2A combined output for USB device charging.\u003c\/li\u003e\n\u003cli\u003eProgrammable lighting control and load disconnect functions for small DC load management.\u003c\/li\u003e\n\u003cli\u003eProtection against reverse polarity connection of the solar panels or battery, plus over-temperature protection.\u003c\/li\u003e\n\u003cli\u003eRemote battery temperature sensor included for temperature-compensated charging.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe unit measures 101.5 x 184.0 x 47.1 mm and weighs 0.3 kg, so it can fit on a compact electrical panel while still leaving room to view the LCD and access the terminals. Its IP20 enclosure is not sealed against spray or washdown, which makes a dry cabin, electrical locker, or sheltered equipment panel the better mounting location.\u003c\/p\u003e\u003cp\u003eThe terminals accept up to 16 mm² or AWG6 conductors. Cable size, fuse placement, and battery isolation should be matched to the vessel's DC system and the controller's 20A charge rating.\u003c\/p\u003e\u003ch6\u003eSolar and battery compatibility\u003c\/h6\u003e\u003cp\u003eFor a 12V battery system, use 36-cell solar panels. For a 24V battery system, use a 72-cell panel or two 36-cell panels in series. Maximum solar voltage is 28V on 12V systems and 55V on 24V systems, so the panel array voltage should be checked before connection.\u003c\/p\u003e\u003cp\u003eThe controller supports AGM, GEL, flooded lead-acid, and LiFePO4 batteries with an internal BMS. Automatic 12\/24V detection applies to standard 12V and 24V operation, but LiFePO4 setups require the correct voltage setting rather than relying on automatic detection.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis controller is a practical fit for boats using solar to maintain both starting and house batteries while moored, anchored, or between trips. The dual battery outputs are useful where the engine start battery needs maintenance charging without giving up solar support for cabin lighting, instruments, pumps, or other house-bank loads.\u003c\/p\u003e\u003cp\u003eThe USB outputs can handle simple device charging at the controller, which is useful in a cabin, nav-station area, or sheltered equipment space. For exposed helm or deck installations, use a separate marine-rated USB outlet in a weather-protected circuit instead of relying on the controller enclosure for splash protection.\u003c\/p\u003e\u003ch6\u003eWhat's included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eBlueSolar PWM DUO LCD and USB 12\/24V 20A charge controller\u003c\/li\u003e\n\u003cli\u003eRemote battery temperature sensor\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52023489429685,"sku":"QBP146563","price":80.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1332215_qbp146563.jpg?v=1780191825","url":"https:\/\/www.qualityboatparts.com\/products\/qbp146563","provider":"Quality Boat Parts","version":"1.0","type":"link"}
