Multifunctional, with intelligent power managementThe MultiPlus is a powerful true sine wave inverter, a sophisticated batterycharger that features adaptive charge technology, and a high-speed AC transferswitch in a single compact enclosure. Next to these primary functions, theMultiPlus has several advanced features, as outlined below;Four stage adaptive charger and dual bank battery chargingThe main output provides a powerful charge to the battery system by means ofadvanced 'adaptive charge' software. The software fine-tunes the three-stageautomatic process to suit the condition of the battery, and adds a fourth stagefor long periods of float charging. The adaptive charge process is described inmore detail on the Phoenix Charger datasheet and on our website, under TechnicalInformation. In addition to this, the MultiPlus will charge a second batteryusing an independent trickle charge output intended for a main engine orgenerator starter battery.High start-up powerNeeded to start high inrush loads such as power converters for LED lamps,halogen lamps or electric tools.Search ModeWhen Search Mode is 'on', the power consumption of the inverter in no-loadoperation is decreased by approx. 70%. In this mode the Multi, when operating ininverter mode, is switched off in case of no load or very low load, and switcheson every two seconds for a short period. If the output current exceeds a setlevel, the inverter will continue to operate. If not, the inverter will shutdown again.Programmable relayBy default, the programmable relay is set as an alarm relay, i.e. the relay willde-energise in the event of an alarm or a pre-alarm (inverter almost too hot,ripple on the input almost too high, battery voltage almost too low).Remote on / off / charger onThree pole connector.On-site system configuring, monitoring and controlAfter installation, the MultiPlus is ready to go. Some settings can be changedwith DIP switches.500/800/1200VA models: remote switch / battery charge voltage / inverterfrequency /search mode. 1600/2000VA models: battery charge voltage /search mode.For more settings use VE-Config or the VE.Bus Smart dongle.Remote configuring and monitoringInstall a Cerbo GX or other GX product to connect to the internet. Operationaldata can be stored and displayed on our VRM (Victron Remote Management) website,free of charge. When connected to the internet, systems can be accessedremotely, and settings can be changed.Features-Multifunctional, with intelligent power management-Four stage adaptive charger and dual bank battery charging-High start-up power-Search Mode-Programmable relay-Remote on / off / charger on-On-site system configuring, monitoring and control-Remote configuring and monitoringSpecification-Cont. output power at 25°C; 500VA-Transfer switch; 16A-Maximum efficiency; 90%-Charge current house battery; 20A What's in the box * 1 x MultiPlus 12/500/20-16 230V VE.Bus * 1 x Quick Start Guide * 1 x Warranty registration sticker
