Inverter Generators - This type of portable generator is very popular with the leisure industry. Producing a very smooth, pure sine wave output, sensitive electronic equipment, like PCs, DVD players etc can be run from this generator, without causing any damage.
Due to their design, they are more compact and lighter, more economical and quieter than conventional generators, this comes at a price, however, being approximately 2-3 times the cost of a similar output conventional petrol generator.
What is an inverter generator? The inverter generator has a petrol engine, driving a small alternator, this feeds the inverter board, which converts the varying alternator current into constant 230v/50hz pure sine wave output.
With a conventional portable generator, the engine runs at 3000rpm at all times, irrespective of the load implied on the generator. An inverter generator will run justat tickover, if a very light load is applied, increasing in revs to match the load, if a heavier load is applied to the generator. This contributes to the improved fuel economy and low noise output of the inverter generator, often called suitcase generator.
Popular makes are the Honda EU10i, Honda EU20i, Robin Subaru R1700i, Hyundai, HY1000Si, Hyundai HY2000Si http://www.genpoweruk.co.uk/product.php?productid=16189 and Hyundai HY3000Si http://www.genpoweruk.co.uk/product.php?productid=16186&cat=262&page=1. Of these makes, the Honda and Subaru are top of the range machines, but at a very high price, however, the Hyundai range is very similar in specification, but at a far lower price.
