Mastervolt Battery Chargers – Mass
A long life for your battery!

Do you want to charge your batteries safely, reliably, and preferably quickly, even when you are in a marina with poor shore power or a limited power supply? Do you also value batteries that have a long lifespan while maintaining their capacity? Mastervolt offers you the best possible solution. The Mastervolt 3-step charging method ensures more power and a longer life for your batteries. Our battery chargers integrate multiple functions, charging your battery safely and completely even when they are depleted. Fast battery charging is guaranteed by the efficient use of the available shore or generator power (all Mastervolt battery chargers have a power factor correction). Mastervolt is Green by Heart.

Which battery charger best meets your needs?
We offer three types of battery chargers:
Charge Pro™: Range of waterproof battery chargers for recreational use and sport fisherman. Multiple outputs allow for flexibility.

ChargeMaster: Suitable for recreational and semi-professional use. Easy to install, it includes a detailed display and easy three-button controls. The ChargeMaster safely charges multiple battery banks at the same time.

Mass: For the tougher tasks in professional and semi-professional situations. With its integrated alarm functions and various certificates, the Mass is the best choice for professionals.

Charging Lithium Ion batteries
Although Lithium Ion batteries are increasingly popular, there can be a lack of clarity when it comes to the charging process. This is not a problem with a Mastervolt system as the Mastervolt battery charger communicates directly with the Li-ion battery.

Make the most of your shore power
The current control function allows you to easily switch the battery charger back to shore power to prevent blowing the shore fuse, even when the shore power drops.

MasterBus compatible
All ChargeMaster and Mass battery chargers can be easily connected to a MasterBus network with only one cable and one connection. What’s more, you have the option for central, local or remote monitoring, configuration and control of your system.
Mastervolt Sine Wave Inverters – Special Mass Sine
An onboard AC installation offers you a wealth of benefits by making possible the use of any domestic appliance, from microwave oven to hair dryer, DVD player to power tools. An inverter allows you to easily convert the voltage of your 12V or 24V battery to 230V/50Hz or 120V/60Hz, so you enjoy all the comforts of home wherever you choose to cruise.

Complete range
Mastervolt offers a complete range of inverters from 300 Watt to 15kWatt in AC Master and Mass Sine models. The AC Master is ideal for small and medium sized vessels, while Mass Sine inverters are mainly intended for larger systems on superyachts and for (semi) professional purposes. Mastervolt offers inverters for 230V/50Hz as well as 120V/60Hz (American voltage).

Proven technology
Mastervolt’s Mass Sine sine wave inverters have proven themselves in the most extreme conditions for over ten years. Although the dimensions and connections of the various models have remained the same, the technology has evolved with the times, resulting in a fast, efficient, one-on-one replacement with minimal downtime. The Mastervolt AC Master inverters are small, lightweight and silent. Installation and operation are incredibly easy.

Completely independent on shore power
Shore power regularly fluctuates and can cause your lights to flicker. Sometimes it may even drop below 180 volt, causing some onboard devices to stop functioning. The Mastervolt sine wave inverter ensures a perfect 230 volt onboard, and makes shore power problems a thing of the past. The pure sine wave current also helps protect your equipment against failures, humming or lines on your TV and ensure a longer lifespan. Ensure you have the correct match between your inverter power and the connected load.

An end to humming with HF technology
Our use of high-frequency switch technology means you can say goodbye to humming transformers. Mastervolt inverters are also small and lightweight to ensure easy installation.

High peak power during start up
The Mastervolt sine wave inverter can provide up to 200% capacity to equipment that requires extra power during start up.

Simple and safe to connect
The inverters benefit from robust connection technology with internal connections for the larger models and a cable and plug and play inlet for smaller models.

Efficient use of batteries
A high degree of efficiency when inverting and the automatic economy mode when there is no consumption gives you longer use of your batteries and more hours on the water.

MasterBus compatible
All ChargeMaster and Mass battery chargers can be easily connected to a MasterBus network with only one cable and one connection. What’s more, you have the option for central, local or remote monitoring, configuration and control of your system.

Optimal ease of operation
Mastervolt’s Mass Sine inverters are easy to operate via controls on the device, via a control panel or remote control text messaging. Plus numerous options for central or local control and monitoring via the MasterBus platform.
Mastervolt DC-DC Converters – DC Master For 12V, 24V & 48V
The voltage required for direct current (DC) can vary considerably onboard a yacht. A bowthruster or a winch often works at 24V, while navigation and communication equipment mostly requires 12V. By using a DC-DC converter, other voltages than applied in your basic system can be reached. They also ensure that all your onboard equipment has a stable power supply with the right voltage.

DC Master Series:
• Recreational and semi-professional use
• Easy to install using included mounting bracket
• Excellent price/performance ratio
• More power available for two minute intervals, ideal for active marine telephone use
• Supplied with mounting bracket, screws and fasteners

Programmable via a desktop or laptop PC
Remote control the Mac or Magic via your laptop or PC or configure your personal preferences. The device has a communication port and easy installation with a PC-Link and MasterAdjust software.

• No unnecessary heat development due to the use of smart electronics
• Continuous output voltage
• Easy to install

3-Step battery charger
Connected to the 24V main battery, the converter can also be used as advanced 3-step chargers for 12/24V gel, AGM, wet or Lithium Ion batteries (Mac and Magic models only).

Please note
• Choose the right input/output voltage
• Do you require galvanic isolation?
• Desired capacity

Energy-saving dimmer function
Many standard light dimmers convert part of the energy to heat and also lose unnecessary energy. The Mastervolt Mac and Magic converters regulate the power supply efficiently and without excessive heat build-up, up to 250 Watt for optimal safety (multiple Mac or Magic converters can be used for multiple lamps).

Over 90% efficiency
Advanced high-frequency technology with modern microprocessors ensures minimum power loss when switching from 24 to 12V and vice versa. If you have many power consuming devices on-board, the parallel use of several units allows capacities of 40, 60 or more amps.

Solid connections
Chrome plated brass connection block with screw terminal or chrome plated fast-on for DC in/out.

Complete package DC Master
All DC Master converters are supplied with mounting bracket, screws and fasteners.
