Product Description

The Renogy 12/24V 50A IP67 DC-DC with MPPT Battery Charger Pro is a dual-source charger that keeps a house battery topped up using both your vehicle's alternator and solar panels. It is well suited to off-road vehicles, boats, and other installs where the charger may be exposed to water or dust.

Solar is given priority whenever it is available, and the charger still delivers up to 50A when solar input is weak, so driving and sunshine work together to refill the battery faster and reduce fuel use. It supports 12V and 24V systems, detecting the system automatically in non-lithium modes, and works with both traditional and smart alternators. A dedicated D+/IGN signal terminal helps it respond to engine status, and an ultra-low 20mA standby draw helps protect the starter battery from being drained.

Built-in Bluetooth and RV-C communication allow real-time monitoring through the Renogy app, ONE Core, or Vision 7. The IP67 enclosure keeps water and dust out, making it a dependable choice for off-road and marine installs.
