Mastervolt AC Master sine wave inverters have proven themselves under the most extreme conditions for over 25 years. These affordable sine wave inverters convert 12 or 24 V battery voltage into reliable 230 V 50/60 Hz grid power, making them ideal for recreational and semi-professional applications. The AC Master series is easy to install and delivers full output, even under the most demanding conditions. The pure sine wave technology provides an outstanding power quality, ensuring the correct functioning of sensitive equipment. The usage of high frequency switching technology eliminates any annoying humming and buzzing sounds.

Representing complete value for money, these ruggedly built inverters provide essential home comforts when you’re far from the nearest grid connection.
