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
1. What type of alternator is this on-board battery charger compatible with?
This battery charger is compatible with both traditional and smart alternators. However, since standard/traditional alternator has a fixed voltage when charging, while smart alternator has a controlled charging output based on operating conditions, it is required to connect the charger to the smart alternator through the Vehicle Ignition Port by the IGN Signal Wire comes with the package.
2. What will happen if the service battery is fully charged?
This Renogy's DC to DC MPPT on-board Battery Charger has a built-in Voltage Sensitive Relay (VSR), thanks to which the charger will Trickle Charge the service battery and maintain its fully charged status, and will also Trickle Charge the starting battery via solar panels. The VSR also ensures reliable isolation between the starting battery and service battery, avoiding charging interference.
3. What types of battery does the charger support?
This dual battery charger supports Gel, AGM, Flooded, and Lithium battery, but please make sure to set the correct battery type once it is installed. For battery settings please refer to the Manual Book.
4. How do I set the battery since there is no display screen?
To change the battery type you will need to press the push button that is located on the PV+ and ALT+ side of the DCDC, then continue to press the button and the LED will display different colors with each representing a single type of battery. Please refer to the manual for Battery Type LED.
NOTES
  • 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.

    Great product

    Posted by Dan on Jul 22nd 2023

    I have had this set up for about a week and it’s working well. It’s well designed and easy to install. I have not used the alternator input yet but this is the main reason I bought this unit.
