Mastervolt AC Master Inverter (12V / 500W)

The Mastervolt AC Master power inverter produces a pure sine wave AC (Alternating Current) output from a DC (Direct Current) input from your boats battery bank. Because of the pure sine wave output, it is safe and reliable and prevents damage to the equipment it is connected to. The inverter is easy to install and features built in protection against over-temperature, overload, short circuit and high or low battery voltage.

The power inverter is robustly built and delivers the full output even in demanding conditions. The high frequency technology used eliminates noise typically associated with power inverters, such as buzzing or humming. It also features an automatic power saving mode, meaning a longer run time and less strain on your batteries.
