{"product_id":"mastervolt-convertisseur-mass-sine-ultra-24v-4000w-masterbus","title":"Ultra 24\/4000 Mass Sine Wave Inverter","description":"\u003cp\u003eThe Mastervolt Mass Sine Ultra 24\/4000 sine wave inverter is designed to meet the strictest electrical requirements for professional and semi-professional marine applications. Converting a 24 V DC input voltage (programmable range 19 to 32 V) into a pure sine wave 230 V AC output (±2%), it ensures perfectly stable power with a total harmonic distortion (THD) below 1%. This signal quality is essential to prevent failures and protect sensitive onboard electronic equipment.\u003c\/p\u003e\n\u003ch3\u003eRated power and thermal tolerance\u003c\/h3\u003e\n\u003cp\u003eUnlike standard inverters that experience efficiency losses above 25°C, the Mass Sine Ultra maintains its continuous output of 4000 W up to an ambient temperature of 40°C. For starting complex, high-energy equipment such as air conditioning compressors or electric motors, it features an impressive peak capacity of 7000 W. Its overall efficiency exceeding 92% minimizes energy losses, while its no-load consumption remains controlled (16 W in normal operation, 7 W in economy mode).\u003c\/p\u003e\n\u003ch3\u003eExtreme scalability and MasterBus network\u003c\/h3\u003e\n\u003cp\u003eWhat sets the Ultra series apart from the classic Mass Sine range is its modular architecture designed for large-scale systems. Equipped with two MasterBus ports and two Sync ports, this inverter allows parallel coupling of up to 10 units to multiply output power. Additionally, it supports complex three-phase configurations (up to 9 units in 3x3), all configurable via the MasterAdjust software interface. This network integration enables precise monitoring and control from a MasterView display or a global supervision system.\u003c\/p\u003e\n\u003ch3\u003eRobust design for the marine environment\u003c\/h3\u003e\n\u003cp\u003eHoused in a compact chassis (472 x 318 x 178 mm) weighing 15 kg, this inverter features electronics protected by a tropicalized coating (conformal coating) resistant to humidity levels up to 95% without condensation. Certified CE, ABYC, and E-mark, it offers an IP23 protection rating suitable for engine room installations. Its internal algorithms also provide complete protection against overloads, short circuits, and extreme battery voltage variations.\u003c\/p\u003e","brand":"Mastervolt","offers":[{"title":"Default Title","offer_id":53723886125396,"sku":"26024000","price":2128.24,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/convertisseur-sinusoidal-mass-sine-ultra-244000_26024000-1.jpg?v=1776761212","url":"https:\/\/skysat.fr\/en-gb\/products\/mastervolt-mass-sine-ultra-24v-4000w-masterbus","provider":"Skysat","version":"1.0","type":"link"}
