The Renogy IP67 50A DC-DC Dual Input Battery Charger with MPPT is a powerful, slim, and waterproof charging solution designed for tight spaces and demanding environments. With intelligent boost and buck logic, the unit seamlessly adapts to both 12V and 24V systems, making it a flexible and future-proof choice for RVs, boats, or off-grid applications.

Smart charging with dual inputs
The charger combines power from both the alternator and solar panels, automatically adjusting charging mode depending on sunlight intensity. Under strong sunlight, solar power is prioritized to reduce strain on the alternator, while the alternator takes over in low-light conditions. This ensures a stable, efficient, and eco-friendly charging experience.

Efficient and flexible
With a maximum charging current of 50A (12V) or 25A (24V) and an output power of up to 720W, the unit delivers reliable energy to the service battery. It is compatible with multiple battery types, including AGM, Gel, Flooded, Lithium, and user-defined settings.

Thanks to advanced MPPT technology, the charger achieves a tracking efficiency of 99% and a charging efficiency of 97%, ensuring every watt from your solar panels is used effectively. Its high conversion efficiency of 94% minimizes energy loss.

Built for demanding environments
The IP67 rating protects against dust, moisture, and extreme temperatures, making it ideal for both marine and mobile installations. It operates in temperatures from -35℃ to +80℃, with a storage temperature down to -40℃. Its compact size of 178.2 × 121.5 × 37.5 mm and weight of only 1.86 kg make it easy to install even in limited spaces.

Communication and control
The unit supports both Modbus and RV-C communication protocols and can be paired with a Bluetooth module for monitoring via smartphone. This allows you to track charging status and system performance in real time.

Protection and safety
To ensure long service life, the charger is equipped with comprehensive protection features, including:

Reverse polarity protection
Overvoltage protection
Over-discharge protection
Overcurrent protection
Overtemperature protection
