12V 30A DC-DC On-Board Battery Charger with MPPT
Renogy's upgraded DC to DC Dual Input Battery Charger now supports 30V 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 30V solar input voltage, expanding your DIY possibilities.
Adapt to Extreme Temperatures
Consistent high efficiency in extreme temperatures with precise battery temperature compensation.
NEG-terminal design for Easy Installation
The all-in-one NEG-terminal design integrates the terminals for the solar panel array, starter battery and house battery, effectively saving installation space.
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.

Frequently Asked Questions
What should be noted when connecting the 30A DC-DC charger to solar panels?
The maximum solar panel input voltage for the 30A DC-DC charger is 30V, and the maximum input power is 400W. Therefore, ensure that the maximum power of the solar panels you connect does not exceed 400W, and the maximum voltage of series or parallel connections does not exceed 30V. The upgraded version includes a Solar Adapter Cable. Remember to use this accessory to complete the connection between the solar panel and the charger after connecting a single solar panel.
How do I disable the "Solar Low Current Shutdown" mode on the 30A DC-DC charger?
The product comes with an automatic "Solar Low Power" shutdown feature for solar power. If you want to disable this feature during use, you can purchase the BT2 Bluetooth module. After connecting it with DC HOME/RENOGY ONE, you can disable this feature through the terminal device.
What size generator is needed to work with the 30A DC-DC charger?
The charger is connected between the vehicle's main battery and the auxiliary (house) battery. The main battery primarily gets its power from the generator. To ensure efficient charging, the input energy from the main battery side must be sufficient. Therefore, the generator specifications for charging the main battery should be at least 1.5-2 times the charging current of the charger, meaning the generator should be rated at 45A-60A.
