Quality material, silent

I was worried about the noise a transformer could make. At 25% load (the equipment on board my boat doesn't require more power) and 25 degrees Celsius, the fan is always off and the unit makes no noise.

The unit is relatively compact and lightweight, which makes installation easy.

General question

maurice h. | Oct 11, 2023

Has anyone purchased the MasterVolt Mass GI7 transformer and what has been your experience?

Answer

W P. | Feb 5, 2024

Unfortunately, there has been no feedback from other customers so far, but we don't want to leave the question unanswered. Mostly these powerful 7 kW electronic versions are ordered and installed by shipyards. Perhaps that explains the lack of feedback. So far we have not received any complaints.
