{"product_id":"mv-mass-combi-pro-243500-100-m38523500","title":"Mastervolt Mass Combi Pro Inverter \/ Charger (24V \/ 3500W \/ 100A)","description":"The Mastervolt Mass Combi Pro combines a powerful 3 step battery charger along with a heavy duty true sine wave power inverter to provide AC output to operate household items. The unit can be connected up to shore power or a generator for charging and the AC output will automatically switch between mains and inverter mode. It has two separate AC outputs, allowing critical equipment to be put on a different circuit to other appliances to protect them from heavy loads. The inverter\/charger is built to be reliable and user friendly, and is equipped with MasterBus Combi integration for easy operation along with the rest of your Mastervolt system.\r\n\r\nThe Mass Combi Pro features the Power Assist function, which prevents main fuses or breakers being tripped in the event of a weak power supply. It also eliminates power failures and dips to maintain reliable performance. The unit is equally capable at handling heavy loads and more sensitive loads, and with a true sine wave output will not cause harm or damage to your appliances. The high frequency technology used eliminates noise typically associated with power inverters, such as buzzing or humming.\r\n\r\nThis model can be used in a 3 phase system, or you can combine up to 10 units in parallel for higher power outputs.\r\n\r\n\r\nSpecifications sine wave inverter\r\nNominal DC voltage: 24 V (19-32 V)\r\nOutput voltage: 180-260 V, adjustable\r\nOutput frequency: 50\/60 Hz (± 0.005 %), configurable\r\nOutput waveform: true sine\r\nContinuous power at 40 °C \/ 104 °F, cos phi 1: 3500 W\r\nMax. peak load: 7000 W\r\nMax. efficiency: ≥ 92 %\r\nMax. ripple on DC (battery at full load): \u0026lt; 5 %\r\nNo-load power consumption on DC (ON\/inverter OFF\/OFF): 26 W \/ 4 W \/ 0 W\r\nEnergy saving mode consumption: 7 W\r\nParallel configuration: yes, up to 10 units (for larger systems, an external transfer system is required)\r\n3-Phase configuration: yes, up to 3x3\r\nSynchronise with mains\/generator: yes\r\n \r\nSpecifications battery charger\r\nInput voltage range: 184-275 V\r\nMax. input current: 16 A\r\nMax. charge current at 40 °C \/ 104 °F: 100 A at 28.5 V, adjustable\r\nBattery temperature sensor: yes, included\r\nBattery voltage sense: through MasterShunt, otherwise automatic compensation\r\n \r\nSpecifications transfer system\r\nAC input (generator): 50 A (switched)\r\nAC input: 30 A (switched)\r\nAC output 1: 67 A\r\nAC output 2: 50 A (switched)\r\nAC input fuse: no\r\nTransfer speed: seamless (\u0026lt; 1 ms)\r\nTransfer voltage range: 184-275 V, adjustable\r\nTransfer frequency range: 35-68 Hz, adjustable\r\n \r\nGeneral specifications\r\nGalvanisedanic isolation: yes\r\nDisplay\/read-out: LED display\r\nDimensions, hxwxd: 472 x 318 x 178mm (18.6 x 12.5 x 7.0 inch)\r\nWeight: 15.3 kg (33.7 lb)\r\nCompliance: CE, E-mark, ABYC\r\n \r\nTechnical specifications\r\nCharge characteristic: IUoUo, automatic \/ 3-step+ for Gel\/AGM\/MLI\/ flooded\/spiral\/traction\r\nRecommended battery capacity: ~ 200-600 Ah (based on gel batteries, may differ for other types)\r\nGround relay: yes, configurable\r\nTemperature range (ambient temp.): -25 °C to 60 °C, derating \u0026gt; 40 °C (-13 °F to 140 °F)\r\nCooling: vario fan\r\nProtection degree: IP23 (vertical mounting)\r\nSafety class: IEC protection class I\r\nHumidity protection: conformal coating, max. 95 % relative humidity, non condensing\r\nProtections: over temperature, overload, short circuit, high\/low battery voltage\r\nPower Assist: yes\r\nMasterBus compatible: yes","brand":"Mastervolt","offers":[{"title":"Default Title","offer_id":51866045055240,"sku":"M38523500","price":3635.45,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/5825\/9208\/files\/f496102f-20ad-436b-ac81-a3f28e122523.jpg?v=1751369223","url":"https:\/\/mecleisure.co.uk\/products\/mv-mass-combi-pro-243500-100-m38523500","provider":"MEC","version":"1.0","type":"link"}
