Description

TheSterling Power 12/24V to 24V 120A DC-to-DC Battery Chargeraccepts a 12V or 24V DC source and provides up to 120 amps of regulated 24V DC charging output. It is specified for large 24V battery banks on 12V systems, allowing a lower-voltage source system to charge a separate 24V destination bank.

Adaptive multi-stage charging supports listed LiFePO4, AGM, gel, and flooded batteries. A status LED provides local charger indication, and an optional remote can add the listed external monitoring function. Included temperature compensation, IP21 protection, ignition protection, variable-speed fan cooling, and reverse-polarity and short-circuit protection are documented.

Battery and Charging Compatibility

The Sterling Power 12/24V to 24V 120A charger supports listed LiFePO4, AGM, gel, and flooded battery types. It accepts a 12V or 24V DC source and provides 24V DC output for a separate destination battery bank.

For a buyer new to this equipment, the charger acts as a voltage-controlled bridge between two DC battery systems. It takes power from the listed 12V or 24V source side and sends regulated charging power to the 24V destination bank. Confirm source-system capacity, battery chemistry, and charging configuration with the relevant manufacturer guidance.

Installation and System Considerations

The charger accepts 12V or 24V DC input and provides 24V DC output at up to 120 amps. It has IP21 protection, listed ignition protection, status LED indication, an optional remote interface, included temperature compensation, variable-speed fan cooling, reverse-polarity protection, and short-circuit protection. The unit measures 13.7 in. by 9.8 in. by 4.7 in. and weighs 12.1 lbs. Installation should follow the charger manual and the electrical requirements applicable to the vessel.

Warranty and Support

Warranty information is not included in the listed product data. Review the manufacturer documentation for product details, setup, and warranty coverage.

Before Ordering the Sterling Power 12/24V to 24V 120A DC-to-DC Battery Charger

Before ordering, confirm that your source system is 12V or 24V DC, your destination bank is 24V DC, and your batteries use one of the listed chemistries. Review the 120-amp output, source-system capacity, optional remote, temperature compensation, IP21 protection, ignition protection, and installation space. You should confirm compatibility with your battery manufacturer and vessel electrical system before purchase.
