I ordered one yesterday. Seems like a good deal, but close call between this and new one from Costco with potential 30% tax credit.

Nice. These are approaching my <$0.50/wH try price. Maybe any 240v charging bugs worked out by then.

Also noting the eBay listing ends with totally not tax advice:

I have one of these...I've done a bit of LifePO4 research but I haven't seen a clear answer as to whether it's ok to let these charge to 100% or not if you intend to discharge it fairly quickly after that. I know long term storage is recommended at 60%.

Should you only let it fully charge to 80% like a phone to prolong battery health? And also should you never let it go below 15%? Yet I thought part of the idea of getting LifePO4 was not to worry about this and to have more cycles than you need. Any input would be appreciated.

What are the requirements for the 30% credit?

Recently got one and the extra battery. It is a really good system. Both for solar (I think up to 1200w input), and as a backup.

One thing to note though: the ground is not "bonded". If you need "utility ground", then they sell a separate adapter. But that cannot be used with AC input. (Long story short, you can only have it at one place. Either at your panel, or in the generator, not both).

I'm going to bite on any Delta 2 deal but doubtful it will happen.

Same here. I thought Costco stopped selling Echoflow because nothing pops up on a search

I'm hoping these will come down in price and eventually a unit with similar specs will be around $1k in a few years. It would be perfect to use as a UPS for my sump pump to guarantee I won't get a flooded basement in the event of a power outage while I'm away from home for a few days.

Why save these on a shelf somewhere for emergencies instead of regular use? You could hook up some panels and run several devices off this daily and save some off your electric bill. I realize the preferred off-grid solution is getting batteries, panels, charge controllers, and inverters as separate units but you have this all-in-one device (minus the panels) and you can get something out of it. It's not going to discharge fully and recharge each day ( depending on your use) so it won't fully recycle and even then you should get excellent use from the battery. Seems a waste to buy one of these and let it sit on a shelf.
