Sine Wave Inverters

True sine wave inverters produce AC electricity that has the same wave form as that supplied by the national grid. Although more costly than our range of modified sine inverters which have an approximated wave form, they run many electrical appliances far more smoothly and reliably. We only sell reliable, good quality brands.

Both the Cotek and Studer inverters are exceptionally well made, and come with a range of protective features. They have an excellent overload capacity, and for short bursts can be used at loadings well above their nominal continuous load rating. They come in a very wide range of power classes for both 12V and 24V DC input systems, which enables the optimal inverter to be chosen for any application - from charging up your mobile phone to powering heavy duty power tools and household appliances.

Mastervolt's ranges of marine-grade pure sine wave inverters are one of the best quality products you can find. Fully featured and designed to work in the toughest conditions, Mastervolt's products have a well deserved reputation for quality and reliability and a two-year manufacturer's warranty.

Mastervolt Combi units are the simple and safe solution for dual voltage systems - a dual-purpose inverter and battery chargers in a single device. They automatically manage all your 12V and 240V systems to ensure that you can power your appliances AND keep your batteries as full as possible at all times. There is no need for any AC changeover switches and no need to remember to switch your inverters and chargers on and off.
