A digital/pure sinewave inverter although more expensive that a standard generator means that the output is modified to produce an output that is safe to use for sensitive electronic appliances DVD's TV's laptops computers etc. Basically it evens out any spikes or variable output that could damage the equipment.
Because the technology ,although it has been around a long time it has been developed to use with the laptop etc. Generally it also means that the generators being more modern are also much quieter that the older styles.
I expect others will add their input so you can get a better picture.
Hi Dawa, I am also a solo traveller, I have got a generator for the off rd. Because I don't intend driving the black tops too often, I am also having an Inverted fitted this week, more for convenience than anything else and apparently will have to have a 1000v? Watt? or whatever to cope with the appliances I would want to use, so I too am at the mercy of being put in the right direction.let us know how you get on Georgie
Just remember to secure your Generator if you do not have it hard wired into your vehicle ,as with almost all insurance covers they do not cover generators/sat dishes/ sola panels .My son was telling me the hottest thing getting tacken at the moment is solo panels he said there appears to be a ready market for them.He should know as he is Insurance.It was also interesting to hear also from him that for every 100 RVs stole the recoverey rate was as low as 1.He said working in conjunction with the police on this matter ,they believe most are re badged /painted ( probably with house paint by brush ) and taken to bush blocks.
Standard generators produce a sinewave at a nominal frequency (50Hz or 60Hz), but the frequency is affected by the rpm of the motor. When the genny loads up the revs drop and therefore the frequency drops also as well as the output voltage. An inverter generator uses the output from the generating coils (AC) and converts it to a DC voltage. It then uses electronics to change it back to AC voltage at a stable frequency which doesn't fluctuate with engine RPM. Some cheap versions just chop the DC voltage (switch it on and off) then feed the resultant output through low pass filters to remove the higher frequencies contained in the squarewave which rounds off the corners on the squarewave, approximating a sinewave. Digital Inverter generators generally use a microprocessor to convert the DC into a multi stepped wave (like a staicase going up then down) and then filter the output to produce a smoother waveform more closely resembling a sinewave. Because the waveform produced from the DC is made up of much smaller steps there is less energy filtered out by the low pass filter so less energy wasted.
