Mastervolt offers a complete range of inverters from 300 watt to 40 kwatt in AC Master, Mass Sine and Mass Sine Ultra models. The AC Master is ideal for small and medium-sized applications, while Mass Sine and the advanced Mass Sine Ultra inverters are mainly intended for larger systems and for professional purposes. Mastervolt offers inverters for 230V/50Hz as well as 120V/60Hz (American voltage).
Our use of high-frequency switch technology means you can say goodbye to humming transformers and hello to efficiency. Mastervolt inverters are also small and lightweight to ensure easy installation.
The Mastervolt sine wave inverter can provide up to 200 % surge capacity to equipment that requires extra power during start up.
A high efficiency when inverting and an automatic economy mode when there is no consumption gives you longer use of your batteries.
The inverters feature robust connection technology, internal in the larger models and a plug & play socket with cable for the smaller models.
Every Mass Sine inverter can be easily connected to a MasterBus network with only one cable and one connection. You can also choose central, local or remote monitoring, configuration and control of your system.
