Delta Powerboats is a Swedish yacht builder with a proud Scandinavian background. It combines modern design concepts with unparalleled craftsmanship, resulting in a series of unique luxury sports yachts for demanding sailors made from 100 % carbon fibre. This extremely strong and lightweight material is 30 % lighter than fibreglass, providing substantial fuel savings.
The company’s latest design is the Delta 88, the new flagship of the series. Thanks to its three Volvo Penta IPS engines, this well-appointed, state-of-the-art boat – in appearance almost the opposite of a sports yacht – can effortlessly reach speeds of 38 knots while remaining easy to manoeuvre thanks to its lightweight carbon construction. The yard demanded that all on board systems be of an equally high quality, which is where Mastervolt came into play. As well as sharing Delta’s love of innovation, our CZone system is the only truly integrated solution for digital switching, control and monitoring that can be used on a glass bridge installation.
The Delta Powerboats system designer wanted a fully digital power system that could easily be updated and checked via the internet. Another requirement, as befits this premier class, was the possibility to fully automate the system via programmable events. One example is setting the generator to automatically start when the batteries are low.
In addition, the system had to be fully accessible for operation and control via a glass bridge and iPad interface. The prestigious Showboats International magazine dedicated a noteworthy article to this system, writing: “While not the first boat to use iPads to control temperature and lights – or check fuel and water levels – this boat has an iPad Pro integrated right into the console. Smart systems include trim tabs for a bit of extra lift aft, a gyrostabilizer for comfort and the CZone monitoring system by Mastervolt.”
Mastervolt Finland was responsible for the comprehensive energy plan and the installation of 11 Lithium Ion batteries, four sine wave inverters, two Combis, six battery chargers and an extensive CZone system with more than 75 components! A year after installation everything is working to the users’ full satisfaction. We are still very proud of the commission and the end result, which turned out to be a very prestigious vessel.
The energy balance shows that there have been no compromises regarding the comfort on board, with a home-from-home electrical power installation providing the ultimate feeling of freedom. And although today’s generators are very quiet, clients want them turned off while the vessel is anchored in a beautiful bay to facilitate complete rest. With a total battery capacity of more than 50 kWh, this yacht can easily go a whole day without using a generator. These solutions are only possible thanks to Lithium Ion technology: incorporating over eight years of experience, the Mastervolt MLI battery offers the ideal solution.
As switching from generator to inverter operation takes place in a split second (one millisecond at most), even the most critical users such as computers and operating systems are not interrupted (and there will certainly be no more flashing lights!).
De parallel geschakelde Combi’s leveren 7 kW vermogen, voldoende om kritische en meest gebruikte verbruikers naadloos om te schakelen van wal- of generatorbedrijf naar omvormerbedrijf (autonoom vanuit de accu’s). Omschakeling gaat zo snel dat computers en PLC systemen, die nodig zijn voor de besturing van het schip, hier geen hinder van ondervinden. Hierdoor wordt de bedrijfszekerheid van het schip gewaarborgd.
De door Mastervolt toegepaste omvormertechnologie zorgt voor een uniek laag standby gebruik, terwijl een ultrasnelle processor zorgt voor een naadloze omschakeling tussen alle beschikbare energiebronnen. Met Power Assist behoren spanningsvariaties en gesprongen netzekeringen tot het verleden, zelfs met een zwakke elektriciteitsaansluiting of een kleine generator. Bovendien zijn alle Mass Combi Ultra modellen uitgerust met MasterBus, één taal waarmee alle apparaten in het netwerk met elkaar communiceren.
When demands are high, as they are on the Delta 88 powerboat, it is crucial to have the best of the best: heavy lithium-ion batteries, like the Mastervolt MLI Ultra 24/5000. These batteries are ideal for heavy loads during long periods, and have a short charging time (less than 30 minutes). By choosing Mastervolt MLI Li-ion batteries, Delta saves up to 70 % in space and weight.
Eight MLI Ultra 24/5000 batteries feed some of the AC consumers (which require a total yield of 440 kWh) so there is always a backup if the generators are not running. Two reliable Mass 24/100 chargers ensure that these batteries are always 100 % charged.
Two AGM batteries of 90 Ah each are used to start the port and starboard generators. The small model from the ChargeMaster series, the 12/25-3, is used to recharge these batteries.
Two MLI Ultra 24/5000 batteries are used as a power source for the DC distribution system in the forepeak, connected to heavy consumers such as the bowthruster, anchor winch and various pumps. A Mass 24/100 battery charger ensures that these batteries are always full.
Safety always comes first! The navigation and communication equipment is supplied with power by means of a separate supply and charging system. The robust MLI Ultra 12/5000 takes care of this important task. The ChargeMaster 12/100-3 ensures that this 12-volt circuit is always on standby.
These batteries are connected in series so that they can start the three 24-volt engines if necessary. A ChargeMaster 24/20-3 has sufficient capacity to recharge these batteries.
The CZone digital control and monitoring network simplifies the installation of electrical systems. This network replaces complex wiring and switchboards with smart robust interfaces and an NMEA 2000 network cable, which increases operational reliability. In addition, CZone also offers an advanced solution for the automation of complex control and monitoring functions on modern marine systems. The CZone system includes built-in timers, dimmers (including support for halogen lighting), alarms, voltage reducers and load shedding. It provides so much more than digital switching.
The owner/captain can receive alarm messages anywhere via an internet connection, even when not on board. Bilge alarm or the charging of batteries when the shore power is disconnected are just two examples of operations that can be conveyed via email or smartphone so that appropriate action can be taken.
The Wireless Interface and free Mastervolt app allow the entire system to be monitored and controlled via an iPad. The Wireless Interface provides a wireless connection between the iPad and the Mastervolt system and can also function as a ‘client’ for the main router, with the advantage that you log on to a single wireless network to use the internet and other applications. Opening the garage hatch from the jetty becomes a lot safer, for instance, and monitoring the tank during refuelling prevents any spilling of fuel.
The yacht is also equipped with the latest Touch 10 CZone control panels in order that the system can also be operated via cable connections. Reliability is guaranteed!
