Looks like an ok price, but not sure about getting this for so much. The amount of KWH is not a lot considering the price. The average house uses 15-30kwh a day, so this wouldn't power much. Even the fridge alone would only last a few days. They usually take about 1-2 kilowatt-hours (kWh) per day.

I was going to pull the trigger on probably a Delta 3 Pro with EB, more so that this but reading all the Reddit posts users and how many units have had problems and what a nightmare their customer is to deal with, I have become kinda scared to buy anything more from them, especially something that's nearly $5,000. And if you have some kind of real emergency situation where you'd really need this, there ain't gonna be no warranty replacements coming through when the grid is down.

Unless you have a solar field, I'm not sure how this has an advantage over a gas powered generator that is easily refillable in an outage.

I guess you haven't actually had an overnight outage where you actually try to sleep with the noisy gas generator, have you?

Every time something like this comes up I'm tempted to buy it as a whole house battery back up, but the comments talk me out of it. Is there a suggested product to buy that comes up on slickdeals that most SDers would agree is the way to go? (I know use varies but just assume an average family- or for a general use case.)

The key is to combine something like the smaller version of this (DP3) with a cheap gas generator to charge your battery pack as needed. That way you won't have to rung your gas generator non stop and will actually be able to get the most out of both types.

You are probably better of with a DP3 and gas generator.

This past July 4th weekend, we had to run ours at night, Thursday to Sunday morning. I had a Dewalt fan blowing in our bedroom, the generator is right outside our window. I could barely hear it but my new neighbors weren't all that amused lol

During summer months it's between 50-70kwh per day for a two adult household in FL in 1700sqft. Even winter months are between 20-40. How do you consume so little power?

I'm assuming they live somewhere that doesn't require AC and they probably have gas heat or something. I've tried my best to lower power consumption even putting my AC at 76/77 during summer with a variable speed heat pump but honestly the amount of costs to improve insulation and stuff would never pay back the savings. It surprises me when I see people with so little usage though.

I am not that low but NorCal bay area here and my house averages 10KWh a day. Planning to get this primarily to peak shave and integrate with solar (roof top installation is the plan). My usage that is not on electric yet is gas WH, stove and central heat. I plan to install a HPWH soon and move my relatively small winter time heating requirements to electric as well. 1500 SFT two story home.

The whole point is to have something that is 100% SILENT and without disgusting fumes. With the 30% tax credit expiring end of this year, 5.6KW rooftop solar and one of these (and with 2-4 batteries) is the way to go and pays for itself in just 3 years assuming you also have an EV to charge from it and count the savings for not have to pay for gas.
