This device integrates a powerful pure sine wave inverter, an intelligent multi-stage battery charger, and an AC transfer system into a single compact housing. Engineered to maximize energy efficiency, it delivers over 93 % efficiency and includes Power Assist to smooth power peaks and prevent tripping of shore power or generator breakers.\u003c\/p\u003e\n\u003ch3\u003eInverter performance and network management\u003c\/h3\u003e\n\u003cp\u003eIn inverter mode, this model delivers a continuous power output of 3500 W (up to 40 °C) with a peak capacity of 7000 W, ensuring flawless startup of heavy equipment. The 230 V pure sine wave output (configurable 50\/60 Hz) provides safe power for sensitive electronics. It features two AC inputs (shore power and generator) and two intelligent AC outputs, one of which is switchable to shed non-critical loads when no external source is available.\u003c\/p\u003e\n\u003ch3\u003eSmart charging and MasterBus scalability\u003c\/h3\u003e\n\u003cp\u003eThe charging module uses a 3-stage+ algorithm compatible with all battery chemistries (flooded lead-acid, Gel, AGM, Lithium-Ion), ensuring fast charging with extremely low DC current fluctuations (ripple \u0026lt; 5 % RMS). A secondary 10 A output is dedicated to charging a starter battery (12 V or 24 V). Unlike standard chargers, the Ultra range offers exceptional scalability: up to 10 units can be paralleled via the MasterBus network to multiply power, or configured to create a complex three-phase network. The Active Optima Cooling system ensures optimal and quiet cooling.\u003c\/p\u003e","brand":"Mastervolt","offers":[{"title":"Default Title","offer_id":53723866661204,"sku":"38343500","price":3133.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_4ea5d4ee-9315-463b-8292-51d4257b71ca.jpg?v=1778020003","url":"https:\/\/skysat.fr\/en-us\/products\/mastervolt-mass-combi-ultra-48-3500-50-charger-inverter","provider":"Skysat","version":"1.0","type":"link"}
