It prioritizes solar and adds alternator power when sunlight is low. Renogy rates it for 50A at 12V and 25A at 24V.\u003c\/p\u003e\n\u003cp\u003eIt's made for RVs, 4x4 vehicles, boats and trailers with a second battery. The IP67-rated case and built-in Bluetooth suit exposed mounting spots, and automatic 12V\/24V matching helps if you upgrade your system later.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cbr\u003e\n\u003ch3\u003eRenogy 12\/24V 50A IP67 DC-DC with MPPT Battery Charger Features\u003c\/h3\u003e\n\u003ch4\u003eSolar-Priority Dual-Source Charging\u003c\/h4\u003e\n\u003cp\u003eThe charger takes solar and starter battery input together and automatically adjusts its working mode to sunlight. It accepts up to 750W of solar at up to 50V, with rigid or flexible panels. Solar charging needs the panel voltage at 15.0V or higher for 10 seconds.\u003c\/p\u003e\n\u003ch4\u003e12V and 24V Compatibility\u003c\/h4\u003e\n\u003cp\u003eIt supports 12V and 24V panels, starter batteries and house batteries. Built-in buck-boost conversion lets it work across mixed voltages, such as a 12V source charging a 24V battery. In lithium mode you set the voltage by hand.\u003c\/p\u003e\n\u003ch4\u003eTraditional and Smart Alternators\u003c\/h4\u003e\n\u003cp\u003eIt works with traditional and smart (Euro 4) alternators. A dedicated D+\/IGN terminal and wire use the engine-running signal to control charging, which helps prevent starter battery drain. Vehicles without that signal can use ALT mode, which starts and stops charging based on starter battery voltage.\u003c\/p\u003e\n\u003ch4\u003eIP67 Case and Heat Handling\u003c\/h4\u003e\n\u003cp\u003eThe die-cast aluminum case carries an IP67 rating. Renogy says the charger holds full output in temperatures up to 113°F without derating. The operating range is -13°F to 158°F (-25°C to 70°C).\u003c\/p\u003e\n\u003ch4\u003eBuilt-In Bluetooth and CAN\u003c\/h4\u003e\n\u003cp\u003eBluetooth is built in, so you can connect to the Renogy app, and Renogy lists RV-C and CAN communication for compatible devices.

This charger uses solar first and fills the gap from the starter battery, so it places less load on the alternator when the sun is out.\u003c\/p\u003e\n\u003ch4\u003eIP67 Case Versus an Open-Vent Charger\u003c\/h4\u003e\n\u003cp\u003eThe sealed, die-cast IP67 case suits wet or dusty mounting spots. The manual still asks for 5.91 in (150 mm) of clearance on every side and says not to install it in a confined space where battery gases can collect.\u003c\/p\u003e\n\u003cbr\u003e\n\u003ch3\u003eBuyer Guidance\u003c\/h3\u003e\n\u003ch4\u003eFuses and Wire Size\u003c\/h4\u003e\n\u003cp\u003eRenogy recommends fuses on both ends. For the 50A model that is a 60A fuse on the auxiliary battery side and a 70A-80A fuse on the starter battery side. For the auxiliary battery, the manual lists 8 AWG up to 5 ft, 6 AWG for 5-10 ft and 4 AWG for 10-16 ft. For the starter battery it lists 8 AWG up to 10 ft, 6 AWG for 10-20 ft and 4 AWG for 20-30 ft.
