running a Waeco on a Non Inverter genset

Hi Paulnsw,

Sorry to differ, but most rotary generators, non inverter, don't produce a good sine wave. Most of them produce an very crappy wave form which can be detrimental to anything electronic, or it simply won't run.

These days inverter units are the way to go.

Racey unfortunatly not a factual statement. They do produce an adequate sine wave and will not be detrimental to anything electronic. Electronic equipment is all rectified to low voltage through power supplies with more than adequate proctection. We have used non inverter generators and still do every day for electronic equipment without issues. The $85 GMC gennies produced an acceptable sine wave form when set at 3,000rpm for electronic equipment. My involvement with small power systems and generators in an engineering capacity goes back to before you were born.

Spot on Faulic.
But also check with Yamah website which quotes the following -
"The EF1000 is the most popular Yamaha generator.The EF1000 is small, easy to carry and can run a microwave, washing machine or small refrigerator"

Guy's, I will concede there may be exceptions to all the rules. However, MOST of the non-inverter generators below say 5kva, simply don't have enough iron to produce a pure sine wave. Generally they produce a very distorted wave, as I said before either wont run or CAN be detrimental to electronic equipment.

The EF1000 is about 10 years old and done only 165hrs from the hour meter I fitted from new. It is not a new EF1000i series.
had it plugged into my old Waeco70L fridge power box and it smoked-it :(
so this is why I was asking if it would run the new 50L waeco that you can have it plugged directly into 240v.

I have had a Yamaha ET 650 for a number of years now and have run an Engle, a Waeco, television, lights and a computer all with no problems.
I have done quite a bit of work in diesel power houses in the past (now retired) but can't recall sine wave being mentioned but power factor was very important as well as AVR. I would say that if a generator has a good AVR running various equipment off it would not be a problem.

Hi
Older style non inverter generators generally give a very good sine wave form
The AVR system if existent may be poor
Many simply have a manual adjustable voltage
Speed control & governor response time can be critical in maintaining the correct frequency.

Simply because a generator is an inverter type does not mean it has a good sine wave output ,particularly under heavy loads.
They can be Square wave[Engel] ,Modified square wave ,[many] & some, very near true sine wave.

The basic inverter circuits are no different to those found with DC To AC inverters
Square, MSW, & PURE.

I think that the new Waecos have their power transformer built in.

Yep 50's and 60's have both 12 and 240 volt inputs

The 240 overides the 12 if connected together as far as I can make out.
