Why are there so many refurbished River 3 Plus's? Can you trust that the cells haven't been run to 0, shortening their life?

I suspect a lot of these were returned because people bought them to use as a UPS, which it was heavily marketed for, but they fall short in a few ways that some find unacceptable. You can never guarantee that a refurb wasn't abused but I have ordered a few ecoflow refurbs including a river 3. They have all looked brand new and none have failed on me so far.

I just got one to use as a ups with some solar energy offset. Why does it make a bad ups?

It randomly shuts off the ac ports which makes it useless as a ups. People have tried setting changes, charging speed changes, etc to no avail. It appears ecoflow support starts ghosting people as they try to get help. Also pushing them out past the easy return date.

FYI: Just bought this deal a couple days ago. The River 3 main unit shipped almost immediately and it looks brand new. The expansion battery still hasn't arrived and is coming from a different warehouse.

There was also a silent hardware revision as they had to completely redo the electronics around March last year to fix some DC offset issues so maybe these were returns that got reworked, or maybe they're just selling them back without any rework in the hopes we don't notice.

This was bad FW apparently but they've never actually gone and fixed it.

The more important issue with using this as a UPS is that it doesn't handle some inductive loads (like PC power supplies, but not all of them), which causes the switchover to go from the advertised 10ms to well over 1 second.

That's a shame wonder if the Anker one is any better but this has 2x the output wattage.
