Washing machine for instance

Might be obvious, but given its an electrical question from some who knows nothing, here goes.
So if you plug in your washing machine In to a mains socket and did a wash. Would doing the same load using say a poweroak ( with adequate kilowatts) use as much electricity and cost the same, given you will still need to charge the poweroak ( other manufacturers are available) but it will be trickle charge over a longer period, as opposed the one big hit from the mains.

The Poweroak (had to look that one up) would use more power you can't get ought for nowt as they say. It takes more power to charge a battery than you get out of it and you have to power the charging circuit, in use it will have electronics running using power.

Thanks was just curious.

To get any savings you would need to use solar panels to charge the Poweroak battery, unless you are still fortunate to have a cheap off-peak electricity tariff; but you might as well use that to run the washing machine anyway.

Solar being fitted in January, but not a washing machine.

For a Poweroak, which has a lithium battery, you would probably get out a maximum of about 80% of the energy you put in, including the losses in the charger and inverter. That's much better than a lead-acid setup, where you'd be lucky to get back 50%. Time-shifting using lithium storage batteries is standard procedure for those with solar plus battery storage, especially in winter when there's little solar and the cheap tariff is in the middle of the night. My daughter charges her electric car on a timer like that, for example.

Why not? We always carry a washing machine.

The only advantage might be if you were somewhere with low power available on hook up. 6amp for example would be insufficient for most machines. I don't know for sure, but would expect the recharge of the Poweroak to use significantly lower current.

My twin tub only uses 160Watts (0.7 amps) with both washer & spinner going, I run it off the inverter.

We did when we lived on the boat, but in our mh, it's not big enough to fit one and we did not get along with the mini ones you put on the drainer/worksurface.

What size inverter u got Lenny HB ?

1000 watt, main use is charging the e-bikes only do one at a time to keep the load down on the batteries.

You run the washer off a 1000w inverter? Mrs Westy will be chuffed, she’s just bought a washer And we have a 1000w inverter, that wouldn’t run my coffee machine, so I never thought it would run the washer What do I know, other than my electrics need an upgrade in the not too distant future

Washing machine is only 160 watts, coffee machines are 1300 - 1800 watts.

WESTY66 I run my , no i dont . the wife runs the washing machine off a 800w msw inverter (£47 toolstation). Also used for a small food processor/onion chopper and charging 24v hoover (Gtech hand held).
