Mastervolt ChargeMaster Plus - 24V - 110 Amp - 2 Bank

The ChargeMaster Plus is the ultimate all-in-one battery charging solution designed specifically for marine and boating applications. Combining advanced charging technology with robust features, it ensures your vessel's power systems are always reliable, efficient, and easy to manage.

Advanced Charging Technology for Marine Power Systems

ChargeMaster Plus revolutionizes battery management by integrating multiple functions into a single, compact device. This next-generation battery charger replaces the need for auxiliary chargers, battery isolators, and Voltage Sensitive Relays (VSR), simplifying your marine power setup while reducing both complexity and cost. Whether you're managing a dual-battery system or multiple battery types, ChargeMaster Plus delivers fast and safe charging anywhere in the world.

Battery’s Best Friend Architecture

Designed for versatility, ChargeMaster Plus can handle a wide array of battery chemistries, sizes, and voltages. Utilizing the efficient 3-step+ charging method, it ensures each battery is charged quickly and safely, extending battery life and enhancing performance.

• Revival Mode: Automatically revives even fully depleted batteries, ensuring you never get stranded with a dead battery.
• Multi-Voltage Capability: Seamlessly charge a 12V starter battery within a 24V system without the need for additional components.
• Priority Charge: Automatically redirects available power to the lowest battery, ensuring faster and more efficient charging where it's needed most.

Global Charging Compatibility

ChargeMaster Plus is built to operate on worldwide AC voltages and frequencies, making it perfect for marine applications that demand reliability in varying environments. Its robust design resists large voltage fluctuations and high temperatures, ensuring consistent performance even in harsh marine conditions. Certified for marine use, ChargeMaster Plus meets CE, ABYC, UL, SAE, CEC/DOE, and RCM/C-Tick standards, providing peace of mind for boaters worldwide.

Simplified System Integration

Modern marine systems require equipment that is intuitive and easy to install. ChargeMaster Plus features an easy-to-read display that shows the charge phase of all outputs clearly, making monitoring straightforward. Its robust and ergonomic connections significantly reduce installation time, allowing for hassle-free setup on your vessel.

Seamless Communication with CZone Integration

In today's connected marine environments, seamless communication between electrical components is essential. ChargeMaster Plus integrates with CAN-based MasterBus, enabling communication with displays, shunts, and power systems using standards like CZone®, NMEA 2000, and CANopen (with additional interfaces). Models equipped with CZone support MasterBus and NMEA 2000 without extra interfaces, allowing for flexible configuration via MasterBus or CZone files.

This extensive range of communication interfaces makes ChargeMaster Plus ideal for comprehensive system integration. Additionally, it can serve as a reliable power supply for sensitive communication equipment or during boat construction phases.
