ChargeMaster Plus 24/110-2 Converter Charger

The ChargeMaster Plus 24/110-2 is a marine battery charger that integrates a DC/DC converter and a current limiter natively. It delivers a total current of 110 A at 24 V and intelligently manages the charging of multiple battery banks simultaneously.

Yes, this is one of its key advantages. Thanks to its built-in DC/DC converter, its second output (DC 2) can charge a 12 V starter battery (up to 15 A) directly from your 24 V system without requiring additional components.

Absolutely. The ChargeMaster Plus is designed to work with all battery chemistries, including Lithium-ion models (such as Mastervolt's MLI Ultra range), as well as AGM, Gel and conventional lead-acid batteries.

The recovery mode is a smart function capable of restoring deeply discharged batteries. This is particularly useful for saving and preserving your service battery banks after prolonged winter storage or severe accidental discharge.

It uses a priority charging function. The charger analyzes the state of your batteries and intelligently redirects the available power to the most discharged battery first, ensuring faster and more efficient recharging of the entire system.

For the 24/110-2 model, it is recommended to use cables with a cross-section of 35 mm² (AWG 2) for wiring lengths under 3 meters, and 50 mm² (AWG 0) for lengths between 3 and 5 meters.

Yes, it accepts a total input voltage range from 80 to 275 V AC (50/60 Hz). It ensures flawless operation in harbors worldwide or even with generators supplying unstable signals.

Yes. Equipped with MasterBus, CZone and NMEA 2000 interfaces, the charger communicates seamlessly with multifunction displays from major brands such as B&G, Garmin or Raymarine, allowing you to monitor charging directly from your helm.

No, it is strongly advised against installing the ChargeMaster Plus directly above a battery that is being charged (except lithium). The potentially corrosive gases emitted by lead-acid batteries can irreparably damage the charger's electronics.

Battery type configuration is performed easily using the DIP switches located on the device. Switches 3, 4, and 5 allow you to select the exact chemistry of your battery bank (Gel, AGM, Lithium, etc.) according to the table provided in the user manual.

The ChargeMaster Plus 24/110-2 delivers excellent power density for confined spaces. It measures 384 x 250 x 127 mm (H x W x D) and weighs 6.3 kg.

The temperature sensor (included) must be installed for lead-acid batteries (Gel, AGM, flooded) to adjust charging voltage based on ambient temperature and prevent overheating. Lithium-ion batteries, however, do not require the use of this temperature sensor.

When new or after a reset, the ChargeMaster Plus requires manual activation for security reasons. It will only start charging the batteries after being activated via the MODE button located on the front panel.

No, this is one of the major advantages of the ChargeMaster Plus range. Unlike older models, the architecture of this charger natively manages voltage distribution and conversion for the secondary output, simplifying wiring and completely eliminating the need for external splitters.

The charger is IP23 certified. It is designed to withstand harsh marine environments and humidity, provided it is installed in a ventilated location and protected from direct water spray.

It uses the proprietary 3-stage+ charging algorithm (Bulk, Absorption, Float) developed by Mastervolt. This method ensures fast, complete and safe recharging while significantly extending the lifespan of your batteries.

The charger is equipped with intelligent ventilation that adjusts to the power demand and internal temperature. At low load or in standby mode, the fan slows down significantly, ensuring very quiet operation.

To integrate it into a CZone network, you must use DIP switch 1 (position up to select CZone) and set a unique address using the other DIP switches. This physical number must match the software configuration of your CZone system.

The charger can operate in environments ranging from -25 °C to 80 °C. However, to protect its internal components, it automatically reduces its charging power when the ambient temperature exceeds 40 °C.

The LEDs on the front panel display the charger’s real-time status and charge cycle progress (Bulk, Absorption, Float). They also indicate any faults, such as reverse polarity, input voltage error, or temperature issues, making diagnosis much easier.
