Draško Marin, dipl.ing. «Elektroničke komunikacije-regulativa, sustavi, norme» With over 39 years of experience, Victron Energy enjoys an unrivalled reputation for technical innovation, reliability and quality. Victron is a world leader in the supply of self-supporting electrical power. Our products have been designed to meet the most demanding situations faced by a diversity of craft, recreational and commercial alike. Victron’s ability to meet the demand for customized off-grid systems is unprecedented. Our product range includes sine wave inverters and inverter/chargers, battery chargers, DC/DC converters, transfer switches, gel and AGM batteries, alternators, battery monitors, solar charge regulators, solar panels, complete network solutions and many other innovative solutions. Products: MultiPlus Inverter/Charger The MultiPlus is a powerful true sine wave inverter, a sophisticated battery charger that features adaptive charge technology, and a high-speed AC transfer switch in a single compact enclosure. The Multiplus combines the charger and inverter functionality. This will result in easy installation and features like Power-Control and PowerAssist. Digital Multi Control Panel With this panel you are able to remotely monitor and control Multiplus and Quattro systems. A simple turn of the button can limit the power supply of for example a generator and/or shore-side current. The setting range is up to 200A. Battery Monitor Key tasks of the Victron Battery Monitor are measuring charge and discharge currents as well as calculating the state-of-charge and time-to-go of a battery. An alarm is sent when certain limits are exceeded (such as an excessive discharge). It is also possible for the battery monitor to exchange data with the Victron Global Remote. This includes sending alarms. Gel, AGM and Lithium-ion Batteries VRLA AGM: design life 7-10 years VRLA GEL: design life 12 years VRLA GEL 2 Volt cells: design life 20 years The AGM range has very low internal resistance making them particularly suitable for high current discharge applications such as for inverters, thrusters and winches as well as engine starting. The GEL model range offer best deep cycle durability and overall longer life. The use of high purity materials and lead calcium grids ensure that for both AGM and GEL products have particulary low self discharge so that they will not go flat during long periods without charge. Both ranges are supplied with M8 drilled, flat copper terminals ensuring best possible connection contact and eliminating the need for battery terminals. The batteries are compliant with both CE and UL specifications in ABS fireproof containers and come with Victron's 2 year world-wide warranty. The market for battery systems is developing rapidly. There is a growing demand for efficient batteries with a large energy density. Victron Energy has a suitable response for this demand: the Victron Lithium-ion battery system. This is comprised of a very modern battery with an advanced control- and security system; the so-called Battery Management System (BMS). The BMS controls the charging and discharging, immediately takes action when certain (critical) values are exceeded and safeguards an efficient energy-transfer. Application: PowerControl: Dealing with limited generator or grid power All models in the MultiPlus range feature powerful battery chargers. When the largest model is working hard it can draw almost 10A from a 230V supply. Using the remote panel it is possible to ‘dial-in’ the maximum current that is available from mains or generator. The MultiPlus will then automatically regulate the charger taking account of other system AC loads and ensuring the charger only uses what is spare. This way it is possible to avoid tripping the mains power or overloading the generator. PowerAssist: Boosting the power available from mains or generator, an innovative feature of Multiplus. The feature that most distinguishes the MultiPlus from other inverter / chargers is PowerAssist. This feature takes the principle of PowerControl to a further dimension by allowing a MultiPlus to supplement the power available from mains or generator to ‘assist’ during periods of high demand. Peak power demand is almost always sustained only for short periods, either a few minutes (in the case of items like cooking appliances) or just a few seconds (in the case of the burst of energy needed to start an air-conditioning or refrigeration compressor). With the capacity of the generator or mains power set on the remote panel, the MultiPlus detects when the load is becoming too much for the supply and will instantly provide the extra power required. When the demand has reduced, the unit returns to charging the battery. This feature is equally effective in large and small systems helping to reduce the required generator capacity or to achieve greater things with limited mains power. There iseven a special feature to enable the MultiPlus/Quattro to work perfectly with portable generators.

Draško Marin, dipl.ing. «Elektroničke komunikacije-regulativa, sustavi, norme» S više od 39 godina iskustva, Victron Energy uživa u ugledu bez premca u području tehničke inovacije, pouzdanosti i kvaliteti. Victron je svjetski lider u opskrbi samohrane električne energije. Naši proizvodi su dizajnirani kako bi zadovoljili i najzahtjevnije situacije s kojima se suočavaju raznovrsni obrti, podjednako rekreativno i komercijalno. Victronova sposobnost da zadovolji potražnju za prilagođenim off-grid sustavima je bez presedana. Naš asortiman uključuje pretvarače i pretvarače/punjače sinusnog vala, punjače baterija, DC/DC pretvarače, prijenosne sklopke, Gel i AGM baterije, alternatore, monitore baterija, solarne regulatore punjenja, solarne panele, cjelovita mrežna rješenja i mnoga druga inovativna rješenja. Neki od proizvoda: MultiPlus Inverter/Charger MultiPlus je snažan istinski inverter sinusnog vala, sofisticirani punjač baterija koji ima tehnologiju adaptivnog punjenja, te prekidač AC prijenosa velike brzine u jednom kompaktnom kućištu. Multiplus kombinira funkcionalnost punjača i invertera. To rezultira jednostavnom instalacijom i značajkama kao što su Power-Control i PowerAssist. Digital Multi Control Panel S ovom pločom imate mogućnost daljinskog nadzora i kontrole Multiplus i Quattro sustava. Jednostavnim okretanjem gumba možete ograničiti napajanje na primjer generatora i/ili izvora iz gradske mreže. Raspon podešavanja je do 200A. Battery Monitor Ključne zadaće Victron Battery Monitora su mjerenje punjenja i pražnjenja struje, kao i izračun stanja i vremena punjenja baterije. Alarm se šalje kad se prekorači određena ograničenja (kao što su prekomjerno pražnjenje). Također je moguće da monitor baterija razmjenjuje podatake sa Victron Global Remote. To uključuje slanje alarma. Gel, AGM i Litij-ion baterije VRLA AGM: životni vijek 7-10 godina VRLA GEL: životni vijek 12 godina VRLA GEL 2 Voltne ćelije: životni vijek 20 godina AGM raspon modela ima vrlo nizak unutarnji otpor što ih čini posebno pogodane prežnjenje velikih struja, kao npr. za pretvarače, potisnike i vitla, kao i za pokretanje motora. Gel raspon modela nudi najbolju Deep Cycle izdržljivost i sveukupno duži život. Korištenjem materijala visoke čistoće i olovo kalcij rešetke osigurava da AGM i GEL proizvodi imaju posebno mala prežnjenja, tako da se neće isprazniti tijekom dugog razdoblja bez punjenja. Oba raspona dolaze sa bušenim M8, plosnatim bakrenim terminalima koji osiguravaju visoku razinu kontakt veze i eliminiraju potrebu za terminalom baterije. Baterije su u skladu sa CE i UL specifikacijama u APS vatrootpornim kućištima i dolaze s Victron jamstvom od 2 godine. Tržište za sustave baterija se razvija vrlo brzo. Sve je veća potražnja za učinkovitim baterijama s velikom energetskom gustoćom. Victron Energy ima prikladan odgovor za ovaj zahtjev: Victron Litij-ionske sustave baterija. Sastoje se od vrlo moderne baterije s naprednim upravljačkim i sigurnosnim sustavom; takozvani Battery Management System (BMS). BMS kontrolira punjenje i pražnjenje, te odmah poduzima mjere kada se prijeđu određene (kritične) vrijednosti i štiti učinkovit energetski prijenos. Primjena PowerControl: U radu s ograničenjima generatora ili strujom iz gradske mreže svi modeli iz Multiplus raspona imaju moćne punjače baterija. Kada najveći model maksimalno radi može povući gotovo 10A iz 230V mreže. Koristeći daljinsku ploču moguće je 'unijeti' maksimalnu struju koja je dostupna iz mreže ili generatora. MultiPlus će tada automatski regulirati punjač uzimajući u obzir ostala AC opterećenja, a osigurava da punjač koristi samo ono što je rezervno. Na taj način je moguće izbjeći prekide iz glavne mreže ili preopterećenja generatora. PowerAssist: Povećanje snage dostupne iz mreže ili generatora je inovativna značajka Multiplusa. Osobina koja najviše izdvaja Multiplus od drugih invertera/punjača je PowerAssist. Ova značajka uzdiže načelo PowerControl-a na višu dimenziju dopuštajući MultiPlus-u da nadopuni snagu dostupnu iz mreže ili generatora kako bi 'pomogao' u razdobljima visoke potrošnje. Vrhunac potražnje snage se gotovo uvijek potražuje samo na kratko vrijeme, bilo na nekoliko minuta (u slučaju kao što su uređaji za kuhanje) ili samo nekoliko sekundi (u slučaju navale energije potrebne za pokretanje klima-uređaja ili kompresora frižidera). S kapacitetom iz generatora ili gradske mreže podešenom na daljinskoj ploči, MultiPlus detektira kada opterećenje postaje preveliko i odmah daje potrebnu dodatnu snagu. Kad je potražnja smanjena, uređaj se vraća u stanje punjenja baterije. Ova značajka je jednako učinkovita u velikim i malim sustavima, te pomaže u smanjenju potrebnog kapaciteta generatora ili za postizanje važnijih stvari s ograničenim izvorom gradske mreže. Također postoji posebna mogućnost Multiplus/Quattro uređaja da savršeno radi s prijenosnim generatorima.
