Sturdy Design for UltraSafe

Comes with sturdy compact design, this Renogy DC-DC On-Board Battery Charger with MPPT can be safely and easily connected to any 12-volt system and allows safe operation in any position or portable devices without the worry of incorrect connections or sparks.

Built-in MPPT Maximizing Solar Power

WIth Built-in Maximum Power Point Tracking (MPPT) technology, this battery charger with MPPT maximizes the solar power when charging from solar panels, and ensures that the loads receive maximum current to be used.

Multi-alternator Compatibility

This Renogy DC-DC On-Board Battery Charger with MPPT is compatible with both traditional and smart alternators. For smart alternator, an IGN Port is featured to connect the Vehicle Ignition for auto-trigger once it detects the vehicle is started.

Built-in Voltage Sensitive Relay (VSR)

When connected with two batteries, it is vital to be able to isolate the two start and service batteries for charging safety. Renogy Dual Input DC-DC On Board MPPT Battery Charger with its built-in VSR allows vehicle owners to enjoy the benefits of fully charged deep cycle service batteries while reliably isolating it to the engine starting battery with one easy-to-install charging system.

Temperature Monitor and Voltage Adjust

Featured with Remote Temperature Sensor Port, the Voyager can measure the temperature at the battery in real-time and uses this data for very accurate temperature compensation for both too high or low battery temperature, and thus adjust charging voltage to assure stable and constant charging to the battery.

Silent and Efficient Heat Dissipation

This Renogy DC-DC On-Board Battery Charger with MPPT was specially die-cast aluminum designed for efficient and ZERO dB noiseless heat dissipation.

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 controller 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 on page 12&15.
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 on page 15 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 15A for each; if the battery charger only connects one of the two DC inputs, the maximum input current will be 30A.
