What washing machine

Postby ericmark » Sun Apr 04, 2010 8:24 am

The supply is 230v 4A and this runs 12v 25A step battery charger into three 140AH batteries and a 3Kva Inverter not true sine wave.

The water is heated with solid fuel, Engine waste heat and fuel oil heater.

Baby on the way want a washing machine which can run on inverter and use as little electric as possible.

Cool washes of course and no thyristor control as this don't work well with inverters.

Any ideas as to makes and types that will fit the bill?

Might be worth a look on the canal boat & boating forums as they will have a lot more experience on models to use.

Already done to date one top loading model has been ID'ed as will work with inverter with non sine wave output sold in Asda for £300.

Big problem seems to be the modern machines all seem to have changed to cold fill only and although one can connect the cold pipe to hot tape not ideal as then rinses also done with hot water.

Control Inverters can run on AC or DC and the wave form does not really matter but because the RMS output is 230v because it is not sine wave the peak voltage is lower than the normal 325v and with some units this can cause a problem.

Since thyristors cut the wave form these really mess up with the square wave form of the non sine wave inverters.

But manufactures do not tell one how their unit works so selecting microwaves, washing machines etc tends to be more by trial and error than being able to select the items able to run on step up inverters not using sine wave which are a lot cheaper than true sine wave type.

Since farms and many other remote locations use inverters to give then uninterrupted supplies I though it would be prudent to try a number of forums in case some one had already cured the problem.

No point in re-inventing the wheel.
