It is designed for campervans, RVs, overland rigs, and boats that keep a separate auxiliary battery for lights, fridges, and other onboard loads.\u003c\/p\u003e\n\u003cp\u003eA built-in MPPT solar input pulls the most energy from connected panels, and the charger switches intelligently between alternator and solar charging, including a low-solar cutoff mode. It works with both traditional and smart alternators, using an ignition signal wire for smart-alternator vehicles, and a built-in voltage sensitive relay keeps the starter and house batteries isolated while trickle-charging both once the house battery is full. The 50A model accepts series-wired panels up to 50V, while the 30A model accepts up to 30V.\u003c\/p\u003e\n\u003cp\u003eThe unit supports AGM, sealed, gel, flooded, lithium, and user-defined battery profiles, and uses a temperature sensor for accurate charge compensation in hot or freezing conditions. All wiring lands on a single negative-terminal side for simpler installation, and protections cover the batteries, panels, and alternator, including soft-start and nighttime reverse-current protection. Options add a Bluetooth module for monitoring in the DC Home app, or a Bluetooth module with the Renogy ONE Core monitoring hub.\u003c\/p\u003e\n\u003ch4\u003eWhat's in the Box (Charger)\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1 x 12V DC-DC Dual Input Battery Charger (30A or 50A)\u003c\/li\u003e\n\u003cli\u003e1 x Battery Temperature Sensor\u003c\/li\u003e\n\u003cli\u003e1 x Battery Voltage Sensor\u003c\/li\u003e\n\u003cli\u003e1 x IGN Signal Wire\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Renogy","offers":[{"title":"50A \/ Battery Charger Only","offer_id":46209713471679,"sku":"RBC50D1S-US","price":307.99,"currency_code":"USD","in_stock":false},{"title":"50A \/ W\/ Bluetooth Module","offer_id":46209713504447,"sku":"RBC50D1S-BT-US","price":324.99,"currency_code":"USD","in_stock":true},{"title":"50A \/ w\/ Bluetooth \u0026 Renogy ONE Core","offer_id":46209713537215,"sku":"RBC50D1S-BT-W02W-US","price":354.99,"currency_code":"USD","in_stock":true},{"title":"30A \/ W\/ Bluetooth Module","offer_id":46209713569983,"sku":"RBC30D1S-BT-US","price":214.99,"currency_code":"USD","in_stock":false},{"title":"30A \/ w\/ Bluetooth \u0026 Renogy ONE Core","offer_id":46209713602751,"sku":"RBC30D1S-BT-W02W-US","price":399.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/1967\/6351\/files\/RNG-260901-M9-_1-21.jpg?v=1789528105","url":"https:\/\/adventuremotion.com\/products\/renogy-12v-30a-50a-dc-dc-on-board-battery-charger-with-mppt","provider":"Adventure Motion","version":"1.0","type":"link"}
