Can 240V appliances be run on 24V


Hope that's not a dumb question. I have a really good LG washing machine 7Kg load. I am wondering if I could put it in my bus and run it on either 24V, or Solar or via the Gennie. The machine is rated at 280KwH/365 Loads using warm water. I prefer cold washes, so would use less, but I think, if I understand it that would equate to .7Kwh per wash. Is that correct? and if so, is that a big energy draw or reasonable? I will be having the Solar professionally installed in the near future.

Thanks for any help.

Hi tropdoug and welcome to our wonderful forum.

No you won't be able to do that unless it's via an inverter of reasonable wattage $$$$

The washing machine works on AC power, your 24 volts is DC and could cause damage if you tried it. Sorry to bear bad news for you.

Cheers

PS there is no such thing as a dumb question, just dumb answers at times. Lol

Thanks Phil
Oh well hopefully a few dollars from selling it will help towards a suitable one. Thanks for the info. I am very new to this life and got a lot to learn.

Hi Tropdoug,wink

That washing machine will not run off the 24volts directly as Phil has said. It needs 240v AC power. However you can fit an electrical unit called an inverter which makes 240 volt AC from the 24Volt battery power. So it could run from the batteries and the solar power as it charges them. It will run off the gennie probably.

I would look again at the specification plate on the washing machine to see how many watts it uses. The figures you have given are the total use over a year. Then you can see what size of inverter you would need with an extra allowance for starting too. Then see if the purchase cost and the installation cost of a suitable inverter is what you want to do. hmm Some fancy electronic machines do not like running on inverters.

If the "gennie" you are referring to is a 240V generator, It will most likely be able to run on that. But if you are referring to the "gennie" in your bus's engine compartment ie your alternator (unless it's a very old bus), then no you can't run it on that.

Inverters have come way down in price. I bought a new 5000w LF Pure Sine wave inverter a couple of weeks back for $305 + $60 postage. I had to be right on board at the end of auction but it paid off. It is a "smart" inverter and only delivers full power to things like freezers for short bursts. It then reverts to 20w to maintain freezer operation. My research indicated that Low frequency Pure sine wave was the only way to go. This inverter weighs about 14kg (I think) and fits neatly under one of the kitchen seats in a vented environment. All it has to do for us is run a 3 drawer freezer (240v) LED Lights all round and anything else that might be plugged in for occasional use. I think it will even run our el cheapo portable induction 2 burner but that is an emergency thing only so not bothered checking. Hope this helps in some way... (oh yeah, 4 panels on the roof and 250ah worth of batteries)
