RENOGY 12V/24V IP67 50A DC-DC Battery Charger with MPPT (RBC2125DS)
Headline
All-weather 50A DC-DC charger with MPPT and dual-input boost/buck for 12V/24V systems
Overview
This compact, IP67-rated DC-DC charger combines MPPT solar charging with alternator input and automatic boost/buck logic to keep your house battery topped up while minimizing generator use. It delivers up to 720W (50A at 12V / 25A at 24V), supports multiple battery chemistries, and gives you Bluetooth/CAN connectivity for monitoring and configuration.
Benefits
Spend less time worrying about battery levels — the charger automatically prioritizes solar and alternator power to maintain your house battery.
Keep more living space usable — a small, engine-compartment-mountable unit frees up storage and reduces clutter.
Reduce generator runtime — efficient MPPT charging and auto-switching lower the need for generator support.
Start reliably — the charger provides a trickle charge to the starter battery so your vehicle is ready when you are.
Monitor and adjust on the go — Bluetooth and CAN connectivity let you check performance and change settings without opening the unit.
Features
Dual-input design: accepts solar and alternator input and intelligently combines them.
Boost and buck voltage logic: supports charging between 12V and 24V systems.
MPPT solar charging: prioritizes solar energy and maximizes harvest from panels.
Automatic mode switching: seamlessly switches between solar and alternator input for continuous charging.
Bluetooth energy monitoring with wired CAN communication for data and configuration.
Compatible with both smart and traditional alternators; input tuning available via Bluetooth or display devices.
Multiple battery profiles: AGM/SLD, GEL, FLD, LI, and USER-configurable options.
IP67 enclosure and glue-filled design for waterproofing and outdoor use.
Comprehensive electrical protections: reverse polarity, overvoltage, over-discharge, overcurrent, and over-temperature.
