Thread: unavoidable laundry

  1. #1

    Default unavoidable laundry

    OK people... I screwed up last time and didn't ask before I purchased, so this time I am doing the right thing by asking first....

    I currently do not have laundry facilities in my off grid house. A trip to town to the local laundry mat is about a one hour trip and fuel prices are making laundry quite expensive. I'm looking to install a washer and am looking for input on what model to select that will be the most battery friendly.

    Is larger capacity and less loads more efficient than smaller capacity and more loads?
    Will my outback inverter (2024) pull the startup of the spin cycle?

    I have a neighbor that recently purchased a pretty high tech unit that has a built in soft start on the motor. The soft start has eliminated the dimming lights in his hallway when the spin cycle starts up, but is it really saving power or just reducing the surge at startup?

    I have downloaded the spreadsheet from energy trust, but thought I would ask you all before I commit to anything.

    Thanks

    I have a pair of 7 year old Fisher Paykel washer driers on Grid Power. They have Permanent Magnet Motors and draw very little peak power (around 300-500 watts maximum each?) and take only ~0.250 kWH per cycle (washer and natural gas drier). I would guess you should use them only with a True Sine Wave inverter (not MSW-Modified Square/Sine Wave) inverter. So far so good.

    Here are a few older threads (using Google and "washer water extractor site:wind-sun.com" as search string--many times easier for find things here in the forum):

    Consider getting an old style wringer washing machine:

    http://non-electric.lehmans.com/sear...%20Washer&rk=1

    Buy it without a motor, and install a honda or B&S gas engine on it. Lehmans (above link) often sells reconditioned old style Maytag wringers that are indestructible! We have been using such a machine for 50+ years. In the net, they use much less water, as you can do multiple loads with one tub of wash water. Start with linens and whites, wring, add dark towels etc, wring, and then do the work clothes. Same on the rinse cycle. 2 tubs of water will do three loads. The wringer also gets more water out than a spin machine.

    Ours, with a honda motor, uses ~1 litre of gas a month. Pretty cheap, very reliable.

    PS Somewhere on this forum there is a picture of my "new machine" salvaged from an abandoned shed,, I can't find the link right now.

    Larger capacity and fewer loads is almost always more efficient.

    We had a Kenmore HE3 (Whirlpool Duet clone) for the last few years and it was a fine washer, However I just got a 2009 LG for a great price. I do not think you have to worry about start up loads on these new front loaders. The motor is controlled by an inverter board and the spin speed ramps up slowly. I think a FX2024 would run it, but you probably would not want to have the toaster on at the same time. :)

    Watching this LG work is an interesting exercise. The water is pulsed in at regular intervals, and it takes a LONG time to get the clothes fully wet. There is basically no water in the tub when the clothes are washing either. The HE3 definitely used more water. I kinda think that the way they get these great energy star numbers is by reducing the amount of hot/warm water in the load to the absolute minimum. Somehow, they still seem to get clothes clean.

    we have a front loading Bosch about 10 yrs old now. has a small basket but it washes best when jammed full. NEVER gets the clothes soaked, and the start stop action lets the clothes beat themselves up so as to dislodge any dirt. Unable to do a K-o-WAtt on it as it is fed from a 220 dryer plug and the washer comes off one leg of that with a euro plug... gets the clothes clean though.

    I agree with Volvo Farmer. The LG will save you electric 2 ways andyou should be able to power it. Motor is direct drive. Saves you money by not using a lot of heated water, spins the cloths dryer so you don,t need to run dryer as long and uses less laundry detergent. Also it is quiet. Most noise comes from the water inlet valves. I really like mine. solarvic

    might i ask you guys for model numbers of these lg machines as there are many models? are they top load or front load? capacity?

    not asking for me, but for general knowledge.

    I have a smaller Sears front load and it easily handles twice the load of the older Sears top loaders. Washes cleaner, spins far drier, and far easier on the clothes. As to start surge - - there isn't any! It very gently eases into motion via inverter motor, drawing 150 to 200 watts depending on load. It's greatest consumption comes after it gradually ramps up to high speed spin, 400 to 450 watts. Kill-A-Watt tested. Bigger machines would surely draw somewhat more, but still nothing at all like the older top loaders with their 1/2 HP split phase induction motors, and the total lack of start surge is amazing!
    1000 watts PV, MX60; micro hydro feeding Morningstar TS-MPPT-60 and producing over 175 watts 24/7 after all losses; 2 SureSine 300; Xantrex Pure Sine 1800/12; six L16 @ 12 volts.

    I see in your signature a 2.5kw Onan genset. Like many, you could run the genset during laundry morning and get some battery charging done at the same time. (I don't, consumption of the washer is not great and it's load is not either)

    I have a Sears front loader with "click and clunk" controls, no led's or touch control buttons, just on/off switches and relays. It's tough to find simple electrical controls anymore. I like that feature as well as the slow spooling up for spin. Clothes are almost dry when they come out at the end of a cycle. Dried by wood heat or outside line reduces electrical consumption too. I've always been too cheap to electrically dry wet laundry.

    The former standby washer for off grid was a Staber. For many years it was the only brand that could relaibly used on modified sine wave inverters without voiding the warrantee. I have one and it works well and is about 15 years old. They use a veriable speed drive and a belt in place of a transmission plus they have a mechanical timer. Its a top load vertical axis machine whihc takes a bit for most folks to fugure out, but the added complexity cuts down on the number of seals.

    Some folks have had some issues with them and have posted their issues but I expect you only hear the bad stories and not from the satisfied users.

    They are not inexpensive. You buy direct from the factory in the US.
