The Korvet system. Superyacht functionality within reach

view system drawing

CANbus networks are increasingly used in the maritime market, offering easier operation and greater comfort for end users. The Korvet 14 CLR from Deep Water Yachts was specifically equipped with the intelligent Mastervolt CANbus technology (both MasterBus and CZone), allowing important data such as the contents of the water tanks and charge status of the service batteries to be monitored at a glance and the associated alarms to be set for every level. The system is also equipped with a GPRS Module for communication via mobile phone (such as text messaging when a battery is running low). Thanks to the integration with leading navigation partners, it is also possible to monitor and control from the navigation displays.

By combining the various activities in one mode, the system can be adjusted to the desired setting in one easy action; for example ‘mode off’ if you do not plan to use your yacht for a longer time period. This command switches off all loads, including the inverter element of the Mass Combi Ultra, and automatically brings the electric battery switches to the right position. It is also possible to configure the deck lighting so it is dimmed when you leave your yacht.

It is now much easier to set the yacht to ‘night sailing’ or ‘relax’ mode. Moreover, Mastervolt digital switching also gives full control over your yacht with only a few switches.

The basics

  • Navigating, monitoring system data and the control of power electronics via a single display. 
  • Digital switching and monitoring of relevant system data via iPad. 
  • A battery charger, inverter and AC transfer system are combined in one casing to save space. 
  • The maximum shore power per port may vary between 4 A to 16 A. A simple and automatic control via the power electronics required to ensure the shore fuses do not blow when more power is consumed. 
  • Availability of relevant system data via mobile phone. 
  • 24 V battery capacity for larger loads.

Energy consumption

System choice

Charger/inverter: Mass Combi Ultra 24/3500-100

The Mass Combi Ultra is a 100 A battery charger, 3500 W inverter and AC transfer system in one. The Combi can be used for all energy sources such as the generator, shore power, batteries and solar panels. It automatically controls and distributes power, seamlessly passing on the available sources. As a result, batteries are always sufficiently charged and there is a stable AC voltage for the use of electrical equipment onboard. This all-in-one solution provides optimal ease of installation and comfort.

Batteries: 4 x MVG 12/200 (24V/400Ah)

This system comprises four series/parallel switched 12 V 200 Ah batteries that create a 24 V battery voltage. The AC and DC loads require a total of 5.9 kWh. Multiplied by a temperature correction of 20 % and a lifespan correction of 20 %, this results in a total consumption of 8.26 kWh, divided by 24 V = 344 Ah. This means that a battery capacity of 400 Ah is required. The service battery in this system functions cyclically (regular 50 % charge/discharge) and therefore uses gel technology. Gel batteries are completely maintenance-free and ideal for cyclic applications such as service batteries.

Monitoring: MasterView Easy

This touchscreen control panel is easy to read and operate. The grey button turns the display on or off or locks it, while all other functions can be controlled using the touchscreen.

Wireless Interface + WI MasterBus connector

Using the Wireless Interface and freely downloadable Mastervolt app, the entire system can be monitored and controlled via iPad. The Wireless Interface creates a wireless connection between the iPad and the Mastervolt system and can also function as ‘client’ of the main router. The benefit here is that you can log in to a single WiFi network to use the internet and other applications.
