I bought a silverline inverter 700Watt from member transtools on E bay, over a Year ago to use with my wind turbines, 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 onto any 12volt battery, or better a battery bank, 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 at all, to being really quite irratating , depending on the build/ design 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 warrantyTurbine with pmg fitted +black rotor £670 delivered.
