ChargeMaster Plus 24/110-2 Converter Charger

The Mastervolt ChargeMaster Plus 24/110-2 is a high-end marine battery charger that natively integrates a DC/DC converter and a current limiter. 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 integrated 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.

Yes. 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.

Revitalization mode is an intelligent function that can restore deeply discharged batteries. It is particularly useful for salvaging 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 battery banks and intelligently redirects 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 35 mm² (AWG 2) cables for wiring lengths under 3 meters, and 50 mm² (AWG 0) cables for lengths between 3 and 5 meters.

Yes, it accepts a global input voltage range of 80 to 275 V AC (50/60 Hz). It ensures flawless operation on docks worldwide or even with generators providing unstable signals.

Yes. Equipped with MasterBus, CZone, and NMEA 2000 interfaces, the charger communicates seamlessly with multifunction displays from major brands like 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 while it is charging (except for lithium batteries). 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 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 heat 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 safety reasons. It will only start charging the batteries after being activated via the MODE button on the front panel.

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

The charger has IP23 certification. It is designed to withstand harsh marine environments and moisture, provided it is installed in a ventilated area 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 battery lifespan.

The charger is equipped with intelligent ventilation that adapts to the power demand and internal temperature. At low load or in maintenance 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 configure a unique address via 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 front-panel LEDs indicate the charger's real-time status and the progress of the charging cycle (Bulk, Absorption, Float). They also signal any faults, such as reversed polarity, input voltage error, or temperature issues, which greatly simplifies troubleshooting.
