Mastervolt 28012500 – AC Master 12/2500 Inverter (230V Schuko & Hardwired, 2500W, 12V) – Pure Sine Wave, Parallel & 3-Phase Ready

The Mastervolt AC Master 12/2500 (product code 28012500) is a versatile and powerful inverter that converts 12 V DC battery power into high-quality 230/240 V AC output. With 2500 W continuous output and peaks up to 4000 W, it supports both plug-and-play Schuko connection and hardwired AC installation. It features a built-in automatic transfer system for seamless switching between inverter and grid, and supports scalable configurations with up to 15 parallel units or 3-phase setups. Designed for quiet, safe, and energy-efficient operation, this unit is ideal for semi-professional use on land or water.

Key Features:

  • 2500 W continuous pure sine wave AC output, peak up to 4000 W
  • Selectable AC voltage (230/240 V) and frequency (50/60 Hz)
  • Integrated automatic AC transfer system (8–50 ms)
  • Parallel support (up to 15 units) and 3-phase support (3 units)
  • High-frequency switching ensures low noise and compact design
  • Galvanic isolation and full suite of safety protections
  • LED display for voltage, load, and status with alarm output
  • Variable-speed fan for optimized cooling and quiet operation
  • MasterBus compatible via optional AC Master Interface
  • CE, E-mark, and RCM certified
