Frequently Asked Questions

What type of alternator is this DC to DC on board battery charger compatible with?

This battery charger is designed to work with both conventional and smart alternators. However, because conventional alternators maintain a consistent voltage during charging, while smart alternators adjust their charging output based on operating conditions, it is necessary to connect the charger to the smart alternator using the IGN cable (ACC labeled) from the product through the Vehicle Ignition Port.

What types of battery does the charger support?

It's suitable for 12V Lithium, Gel, AGM, and Calcium batteries. This charger enables the batteries to reach a full 100% charge. Additionally, it has the capability to revive lithium batteries that have become discharged to a low voltage.

How do l set the battery since there is no display screen?

To change the battery type, press and hold the SELECT button on the side of the battery charger. The LED lights corresponding to each battery type will illuminate in sequence, indicating the available options.

If both solar power and the engine are available, can we prioritize using solar power to charge the battery?

Our product defaults to DC charging. To prioritize solar charging, simply press the SELECT button on the side.

Can solar charging and DC charging be switched automatically?

Solar and DC charging will automatically switch based on the following conditions: 1) When the generator is running, the system will switch from DC to solar charging if DC input voltage is <11.3V and solar input voltage is >13. 2V) When the generator is off, it will switch to solar charging if DC input voltage is <12.7V and solar input voltage is >13V.
