Mastervolt CombiMaster 24/2000-40 (230V) Inverter / Battery Charger
The Mastervolt 35022000 (Model: CombiMaster 24/2000-40) is a compact, heavy-duty marine/industrial 24V sine wave inverter and automatic multi-stage battery charger. Delivering a pure sine wave output of 2000 VA (1600 W continuously at 40°C) and an integrated 40 A 3-stage+ battery charger, it provides seamless AC power management for onboard 230 V 50/60 Hz appliances from a 24 V battery bank.
Featuring an ultra-fast 30 A automatic transfer switch, the CombiMaster switches instantaneously between shore/generator power and battery inverter mode without interrupting sensitive electronics. Built-in MasterBus, CZone, and NMEA 2000 communication interfaces allow complete integration into modern marine digital switching and monitoring networks.
