12V 50A DC-DC Dual Battery Charger
Renogy's upgraded DC to DC Dual Input Battery Charger now supports 50V solar input, delivering faster and more efficient charging for your house battery.
Intelligent Charging Mode Switching
Charge with advanced logic and 'Low Solar Cutoff Mode' for optimal performance in variable weather conditions.
Versatile DIY Options
Enjoy enhanced customization with the ability to connect solar modules in series up to 50V solar input voltage, expanding your DIY possibilities.
Adapt to Extreme Temperatures
Consistent high efficiency in extreme temperatures with precise battery temperature compensation.
Comprehensive System Protections
This battery charger features multiple intelligent protections for batteries, solar panels, and the alternator, safeguarding your system and ensuring optimal charging.
Soft Start Circuit Design for Enhanced Battery Stability
The soft start circuit gradually increases the charger's input voltage, preventing sudden overvoltage and over-discharge.
Protect Your Solar Panels at Night
At night, the battery's voltage can exceed that of the solar panels, potentially causing reverse charging from the battery to the panels and leading to damage. Reverse current protection eliminates this risk, ensuring system safety.
1. Do not reverse the polarity since the reverse polarity of the battery connections can cause injury and damage to the device.
2. When connecting the charger and the battery, make sure the battery poles are clean when connecting the terminals, select a sufficient cross-section for the connection cable, tighten the nuts and bolts with proper torque as loose connections may cause overheating.
3. Be careful not to over-torque the terminals on the DCDC as over-torquing may cause irreparable damage (Do not exceed 16 N-m / 3.3 ft-lb).
4. Use the following cable colors:
Red: positive connection
Black: negative connection
5. If the battery charger is connected to the starting battery and solar panels at the same time, the maximum input current will be 25A for each; if the battery charger only connects one of the two DC inputs, the maximum input current will be 50A.
