I recently bought a silverline inverter 700Watt from member transtools on E bay, to use with my home wind turbine, and found it an extremely efficient product.

 These aren't  as cheap as imported Chinese Inverters, often 30-40% dearer , but what IS  most impressive with all this range of units, is the level of A.C. "smoothing" , for  anyone who hasn't used an inverter previously you connect the crocodile clips on any 12volt battery switch it on and you get 230 volt, but often if you use them for T.V. or other digital equipment you can sometimes get a faint buzz or one or two lines accross or at the bottom of a T.V. or plasma screen, as they use a "modified" sinewave.This can vary from being barely noticeable to being  quite irratating , depending on the quality of unit your using.

 Not the case with these units, it happily runs the microwave 42 inch T.V., Virgin box, laptops everything i have tried so far with no noticeable drop in performance at all, and no interference as with some Inverters. so if you are considering buying an Inverter i would recommend paying a little extra for one of these.You also get an extra years warranty.
