DC-DC Battery Charger Installation
DC-DC Battery Charger Details

The DC-DC battery charger will charge your house batteries from the starter battery to make sure it optimally and automatically charges to 100%. During the whole process, we use a 3-stage charging method (Bulk, Absorption, and Float) to protect the inverter and batteries.

3-Stage Charging Process Diagram

Changing chargers is not a problem anymore. With just a simple turn of a switch, you can change among STD, Gel, AGM, and LFP batteries. *A fully charged lithium battery will accelerate battery aging and affect battery life. Therefore, we adjust the charging voltage in LFP mode to 13.8V according to the charging and discharging characteristics of lithium batteries to effectively extend the battery life.

Battery Type Selector Switch

DC-DC battery chargers isolate the input and output to prevent voltage transfer errors and interference with household battery charging. Equipped with multi-functional safety technologies such as over-voltage protection, over-temperature protection, and reverse polarity protection, it is safer to use.

Safety Features Protection

This DC-DC battery charger is compatible with traditional and smart alternators. The D+ ignition wire can identify whether the generator is started, prevent the starting battery from being over-discharged, and protect the generator. The LC wire can automatically adjust the charging current to prevent excessive charging current from damaging the household battery. 18-16AGW or 22-20AWG copper cable is recommended.
