I already have it. It uses electricity like crazy but it does the dishes in1/3rd the time and the dishes are always clean. Now if only they still made the filters for it.Govt is in the process of mandating the most efficient dishwasher (and other appliances)... so just wait a bit. No need to make effort to figure it out for yourself

That I don't know. I don't have access to where the dishwasher is plugged in to run it trough a kill-o-watt meter. It might even be direct wired; I wasn't there the day it was installed during construction. But I do know from passing by the MATE3s control screen on my Outback system, most of the time the dishwasher is running, it only pulls serious power when it is bringing the water up to temperature or intermittently during the dry cycle. Most of the time it's running, there's little power above background going to the washer.
The water line to the dishwasher comes from the hot side of the household water supply so the dishwasher only needs to heat it up a little more to get it to proper wash-temperature. The power needed for drying only draws intermittently so even that power load is not what you think it might be.
I have an 8,000 watt inverter, 840 amp hour lead acid battery and 4200 watt solar array. Running an energy efficient dishwasher is not an issue unless I'm three days into very thick cloud cover and trying to make it to the next sunny day without reliance on the backup generator. At that point, it's just a personal decision as to wait to run the dishwasher another day or let the backup-generator kick on once the dishwasher pulls battery power down to that point.
I know everybody's situation is different but if you're having trouble running an efficient dishwasher off-grid, you probably have a system design issue, not a dishwasher issue. Properly sized, your off-grid system should be able to handle such things as laundry, dishwashers and such.

Just for you - here's the Bosch model I installed 5 years ago; probably a different model # for what's available now but it's a place to start:

Catch, make or grow everything you can.
My own DW uses about 1.3kWh for a complete wash cycle including the on-board water heater but "quick dry" function turned off.
With quick dry ON it uses over 2kWh for a complete cycle.

Has anyone looked at the smaller countertop/sink bin type?
It seems the average annual use for a typical electric dishwasher is estimated at 270kwh
For the sink bin type they estimate 175kwh and for the 120v counter top type they estimate 200kwh
Both are significant decreases while much less capacity, takes care of the day to day just fine

What's in a title?
Never new such a thing existed, I think I need one to have a reason for leaving dishes in the sink...

Whatever you did, that's what you planned.
Believe or not, hand washing your dishes uses way more water than a dishwasher.
Keep in mind this is a discussion about a trying to saving less than 200 watts of glass (PV).

I was surprised to find my dishwasher used only 100WH per use without the heater connected.
How were you able to do this?

But if the sun is not cooperating, 2000W of glass will not solve this. Dec 2023 for example.

I never worried about efficiency as we only run the DW on sunny days. During extended long periods of no sun, the old hand washing routine comes in.
I heard this model is pretty efficient and doesn't involve handwashing.

The problem is the cycle is too long. Pretty sure the element isn't used for drying anymore, just to keep the water hot during the two hour cycle. They've taken the water requirements down to the point that you have to use humidity to help release the food from the dishes. It's really quite silly.

Depends on how much water you use rinsing and scraping before you put them in the DW. As a general rule this is correct though.

It's like pulling teeth to get my wife to use the dishwasher. I replaced it about 25 years ago and it probably gets used once or twice a year. I have to convince her that it needs ran to keep the seals and piping in shape.My wife… is the washer & I am the dryer…
Everything else uses WAY more energy & water.

Pretty sure the heated dry is optional if it's on there. I would never use it here for sure, open door wait a few minutes, shake off the plastics. Water heating is likely to be built-in because of the high humidity needs. It's how they make them clean with a few thimbles of water.
