    As far as I know a sinwave is always smooth electric and a normal one can surge and blow things up like puters and tv`s...

    Summat like that any way.. :RollEyes::thumb:

    I dont know.... :RollEyes:

    When your having hanky panky with some one elses wife in your M.H and another Funster drives by..:Wink:

    I think Sinwave is spanish or French for no waves... so it is a constant supply of electric and all smooth... And not going up and down like when an ordinary one can surge and faulter, thus the electric aint smooth..:thumb:

    lol no meant is sinewave the inverter 1 and i would never get a disturbance when in the art of mmmmmmmmmmm :Rofl1::Rofl1::Rofl1::Rofl1::Rofl1::Rofl1:

    Try this one then... :thumb:

    (Copied).. Pure sine waveA pure sine wave inverter produces a nearly perfect sine wave output (less than 3% total harmonic distortion) that is essentially the same as utility-supplied grid power. Thus it is compatible with all AC electronic devices. This is the type used in grid-tie inverters. Its design is more complex, and costs more per unit power

    Just buy a "Honda" Sine-wave and be happy...

    Found this.


    An inverter generator typically has an engine that can be run at variable speed depending upon the load. The engine is connected to an efficient alternator whose output is converted to DC by a rectifier and smoothed somewhat by capacitors. This raw DC power is then inverted into smooth AC power of the proper frequency and voltage for the output (for example 110-120VAC 60HZ or 220-240VAC 50 or 60 HZ). Regulation is very good and the system will use less fuel if the load is small or variable since the control system will allow the engine to idle down when the load is small or throttle up when the load is large.



    A standard "generator" or "genset" is an engine connected to an alternator and run at a speed that is some multiple of the desired AC frequency, regardless of the load on it (as the load increases the throttle opens more to keep the engine speed the same). The output of the alternator is connected directly to the load. Typical speeds are 1800 or 3600 rpm in the USA for 60HZ power when using a 4-pole or 2-pole alternator respectively. The engine speed control can be as simple as the mechanical feedback governor system used for any constant-speed engine.

    Unless you want to faff about mixing oil and petrol I wouldn't bother.
    It's a 2 stroke engine.

    Why isn't the original packing available ?
    Possibly re-badged cheap Chinese made ?

    I would be very wary.

    The pure sine wave is a bit of a red herring. A cheap non inverter genny will produce a pure sine wave simply as a natural effect of the way it is generated. The problem is the voltage is not particularly stable and this is why an inverter genny, which does have a constant voltage regardless of load or speed, is kinder to your vans electronics.

    To put it simply, a pure sinewave generator uses an inverter to convert the voltage to a fully regulated and stable level even if the engine is not kept at the same revs. A standard generator will produce a sinewave (as already mentioned) the output voltage goes through an automatic voltage regulator but can fluctuate if the engine speeds up or slows down.

    Cheap non-inverter generators produce wild fluctuations in voltage. In attempting to govern this, the wave form may be truncated to match the target 230V RMS AC output. This can result in a square wave form (as the peaks of the sine wave are cut off) and this can be very damaging to sensitive equipment. A similar problem can occur when over-driving a cheaper HiFi amplifier by loading it with speakers that are too demanding for the quality of the amp, then whacking up the volume: the wave gets 'clipped' at the peaks and the resulting square form wave destroys the speaker coils.

    Have a look at this paper from Sterling Power (it's a bit old now, but still relevant): http://www.sterling-power.com/images/downloads/generator compare sine wave.pdf

    Quite expensive on postage over there! I have a dealership for an Austrian company. They posted me a cable last week - on a small jiffy bag, only a piece of auto cable about three feet long. £40 postage.

    Check the postage/import costs before you go ahead! On the plus side, their postage is very efficient - ordered at 4pm, tracker has it at the airport terminal being loaded by 6pm.

    This sale look's like from a private person, and not from a company, private person NO Garentee, 2, if from a company then why no fixed price 3 could it be a scam? watch out,:thumb:

    the only suit case model i could find and is exactly the same looking and color etc, except different sellers stickers is from Swiss kraft,to me it looks like a cheap Chinese imitation, be on your guard Bill,
