Description
The Mastervolt AC Master 12/3500 is the most powerful AC Master 12 V inverter, converting 12 V battery power into reliable 230 V grid-quality electricity with a continuous output of 3500 W. Built for recreational and semi-professional use, it delivers full output under demanding conditions and is rugged, easy to install and ideal wherever substantial off-grid mains power is required.
Pure sine wave technology ensures excellent power quality for sensitive equipment, while high-frequency switching keeps operation free of humming and buzzing. As one of the larger AC Master models it provides both hard-wired and plug connections plus an integrated transfer system that switches automatically between the inverter and shore or generator power. A temperature and load controlled fan and an automatic power saving system keep it efficient and quiet.
For larger installations, up to 15 units can be combined in parallel, or three units can form a three-phase system. The inverter is MasterBus compatible using a MasterBus AC Master Interface and can be switched off remotely with the optional AC Master Remote Control.
