Australian designed and manufactured to the highest standard. No matter whether you simply want to power your laptop, charge your PDA in the car or power an entire house or caravan we have an inverter that is right for you. From 200W to 4000W the Excelsior range offers remarkable affordability combined with unrivalled reliability.
We are often asked why do Excelsior inverters cost more than inverters found in mail order or electronic supermarkets? It is a good question, a quick glance at the specifications might suggest that all inverters are equal - have another look! A good indication is weight, our sinewave inverters use heavy duty toroid transformers which add to the ruggedness of the design and are essential for trouble-free operation under a wide variety of operating conditions and loads.
