After a lot of debate I purchased two of these around a week or so ago. Feeding Gemini the stats and Duquesne Light's ToU prices it found that I could theoretically achieve a 3 year RoI period if I can offset the full capacity everyday for 3 years and that at the end of this period it should have around only 4% capacity degradation. This is including tax on the sale and for power losses going AC->DC->AC.
Pretty good IMO, especially when you consider Storm Guard can run in the background and override ToU planning if there's a NWS storm warning. I have one running as a fridge backup and ToU offseter. I logged the daily power draw on my fridge and it's right around 1kW a day. So for ~$600 I have a fridge backup that should last a very long time, can backup the fridge for 2 days, and is slowly paying itself off while taking up about the same room as the lunchbox next to it on top of the fridge.
The other one is running our second floor office window unit A/C as a ToU offset specifically, since it can definitely burn through 2 kW in the 6 hour peak-use period. It's been running without issue so far. In case of a storm, it'll also juice up to 100% and i have 2kW place wherever it's needed in the house. If they run out, my truck's 100ish kW battery can always top them up in an hour. Debating buying a third for the basement dehumidifier that pulls 3-4 kW a day.
Usually these are for camping, off grid and backup power. For people on expensive Time of Use (TOU) plans like California PG&E, there could be a use case here to run a window or portable air conditioner off this during peak times, then charge this with solar or off peak grid power. The savings would be small, not worth it for most people. But since this is rated for up to 10000 charge cycles (until capacity drops to 60%) and the inverter is so efficient, this could be viable for TOU power flexing to save a little money or offset some of the cost.
The Anker SOLIX S2000 stands out as a compact, efficient 2,010Wh portable power station that works especially well for UPS backup and time of use load shifting. The low idle draw, high inverter efficiency, and 35 to 36 pound weight make it unusually portable for its capacity, and the app, Storm Guard, and fast switchover add real utility. It can run fridges, window air conditioners, and other household loads for backup or peak shaving. Main drawbacks are the 1,500W to 1,800W output ceiling, 400W solar input, no 12V output, and a fan that can get loud under load. It is a strong fit when efficiency and size matter more than raw output.
Home backup users wanting a compact UPS, because it has UL1778 switchover, low idle draw, and enough capacity to keep essentials running longer than a typical computer UPS.
People on time-of-use electricity plans, because it can charge off-peak and discharge during peak hours to offset higher rates.
RV and camping users needing a lightweight two-kilowatt-class battery, because it weighs about 36 pounds while still delivering strong runtime efficiency.
Households backing up a refrigerator or window air conditioner, because it can run those loads for hours and still leave meaningful battery remaining.
Desktop computer owners needing graceful shutdowns, because it cannot automatically warn the computer before the battery runs down.
Homes with a 12V fridge or other 12V-only gear, because it has no 12V output.
Users who need high continuous AC output, because the inverter tops out at 1500W and can feel weak versus larger competitors.
People who will keep it near a desk or bedroom, because the fan can growl loudly under load even on the latest firmware.
The inverter idles under 6W and reaches about 96% efficiency, which can extend runtime between charges.
The biggest limits are 1500W AC output, 400W solar input, and no 12V output for a 12V fridge. It also only supports 2.4GHz Wi‑Fi for TOU setup and can be less suitable for devices that need graceful shutdown or higher surge capacity.
It appears to be a regular sale price rather than a deep MSRP cut, and several comments suggest it is already near the best value for its capacity. A lower Black Friday price is possible, but expectations are only for a modest drop, roughly into the mid-$500s.
Yes. It has UL1778 switchover UPS certification and can charge off-peak while discharging during peak hours, making it useful for backup power and TOU savings. The TOU mode depends on Wi‑Fi, and if Wi‑Fi drops it falls back to UPS mode instead of continuing the scheduled peak discharge.
The fan is the main complaint: it can be unusually loud, growly, and more noticeable than the decibel rating suggests, even at low RPM. Latest firmware does not appear to eliminate it, so it may matter if the unit will sit near a desk or living space.
Yes for moderate backup loads: one unit reportedly ran a side-by-side refrigerator for about 16 hours with 42% battery remaining, and another setup was used as a fridge backup for about two days. For multi-day outages, a larger battery may be needed to avoid frequent generator runs.
Coupon code 'POWER10' takes 10% off at Outbound Power to bring it down to $540+tax. The weight and idle draw is insanely good for a 2kwh class battery. Too bad the AC power output of 1500w is pretty puny compared to competitors. The Bluetti Elite 200 can output 2600w continuous compared to 1500w of the Solix S2000. Fantastic deal if the wattage limit is not a problem for you.
Maybe dumb question but is this better\worse\same as a similarly priced computer UPS? Is it the ability to charge with solar that's differentiates it from a 'regular' computer UPS? If no difference that's ok I'm wondering if I should consider this type of power backup instead.
It's not better or worse. It's different.
Power stations such as this one are fine as power backup. They tend to be more expensive, but also hold more power (=longer run time without wall power).
Your run-of-the-mill computer UPS (APC, Cyberpower, Triplite, etc.) tends to be cheaper and have a shorter run time, but it also is capable to communicating with your computer to shut it down gracefully before the batteries run down. This is important because just crashing your computer is not a Good Thingâ„¢. They will have much faster switching times, which reduces the chances of the load turning off while switching to battery. This class of UPS also tends to offer power protection for surges, as well as under- and over-voltage.
If it's fine that whatever you plug into it may turn off without much warning, then it may not matter which you choose. Whichever you go with, just know that it must be plugged into the wall due to the power draw.
All that said, you should not be seeing the same prices for these things, so look again.
1x USB-C (15W max)
1x USB-A (12W max).
Why add these at all bad design wasted real estate.
5 plugs waste maybe do 2 and let us daisy chain because they use better wiring like low gauge copper wires instead is much better.
Also no 12v dc outlet wasting energy that doesn't need ac. Main issue tested ecoflow 12v cig wastes energy because it can't run a vehicle cooler wtf. And throws error on startup because it panics when it spikes by 0.5 sec and drops it can't handle shit
Alt text: Man shakes fist and complains that this model does not have the exact features that he wants even though there are models that do

I bought it a few weeks ago. It's a good an efficient unit, but the fan is obnoxious. It's not even the decibels, it's the pitch ... it growls even at low RPM. I'm on the latest firmware.

I 100% agree - worst thing about this unit by a long mile.
Otherwise it's fantastic but the fan is preventing me from picking any more up in the future until they sort it.

So if I just bought a generator from Costco for 3kw, would this battery backup with 400w of solar (which is not great for a battery this size), I would be covered for all extended power outages like from a hurricane since I live in Florida.

The last time I had a hurricane-related power outage, it was off for almost five full days
You might want to look at a much larger power station to avoid having to run the generator as often in an extended outage

The unit supports UPS-style switchover with UL1778 certification, which can help protect sensitive electronics during outages.
The Storm Guard feature can top up to 100% after weather warnings, which can improve readiness during storms.
The S2000 can run a side-by-side refrigerator for about 16 hours while showing roughly 42% battery remaining.
The fan can be unusually loud or growly under load, which can be a dealbreaker for quiet operation.
The Storm Guard charging behavior can jump to 1600W regardless of the selected charge rate, which can trip breakers when multiple units run together.
The TOU mode requires a 2.4GHz WiFi connection and can fall back to UPS mode if WiFi disconnects, which can disrupt peak-period switching.
The AC output limit of 1500W can be weaker than some competitors that offer around 2600W continuous output.

Found that out the hard way when I started getting warnings of air quality and it turned on and my breakers tripped.
I'm assuming it's a simple fix in the firmware where they'll allow for an option that says 'when storm guard activates, charge at chosen rate'.
It would have been nice if they'd rested it before release....
