Mastervolt MASS GI 7 Isolation Transformer
No more galvanic corrosion at the berth: The Mastervolt MASS GI 7 galvanically isolates the shore power grid from the onboard electrical system, reliably protecting the underwater hull, propeller shaft, and all other metal parts from corrosion damage caused by stray current. With 7,000 VA of power and modern high-frequency technology, it is significantly lighter and more compact than classic low-frequency transformers – a real step forward for the demanding blue-water sailor or motorboat owner.
Tip: When planning a new installation, make sure to reserve space for a second MASS-GI device – by connecting them in parallel, the power can be easily doubled as onboard power consumption increases.

- Galvanic isolation between shore power and onboard electrical system – reliably protects metals from electrical corrosion
- High-frequency technology: up to 75% lighter and 60% smaller than conventional low-frequency transformers
- Integrated soft start reduces inrush current peaks and protects the onboard electrical system when connecting to shore power
- Wide-range input 90–255 V / 45–65 Hz – works in marinas worldwide, regardless of local mains voltage
- Parallel connection of multiple devices possible – easily scale performance as needed (e.g., 2 x 3.5 kW = 7 kW)
- LED display for load and overload, plus connection for remote control directly on the housing
