Deal Details
Great price for a delta max 1600 with expanding capabilites. can handle 2000 watts and surge to 5000w. also has the ability to add two extra max batteries bringing this capability up to approx 5600 watts.

This is a refurb with a 2 yr ebay warranty.

And before the critics chime in, it is Li-on but great for emergency infrequent use as a home power backup source for major appliances.

Arguably the solar panels are generating the power, not the battery.
That is just a fact it doesn't need to be argued 😂

These shouldn't be left plugged in like a UPS, not great for the batteries and too bulky.

The two main uses are emergency backup power, and off grid use (camping).

The first use is the main reason I bought mine. Wildfires, high wind events, etc PG&E likes to turn off the power for undisclosed amounts of time. Obviously, I have a generator suitable to run the whole house, but it's not a good idea to run it constantly just to keep the fridge cold, especially when roads are shut down and gas supply is dwindling. Instead, my ecoflow can run my fridge and internet (only communication where i live) for 28hrs on one charge. Run the gen for 1.5hrs and I'm good for another day. I also have 250w worth of solar panels to keep it topped off for those major outages.

Even for shorter outages, I'll plug the TV and fridge into it so I don't have to lug out the generator for a short 6hr outage.

Also a plus for camping, running lights around the campsite or when we have older family members with us to run small appliances they just can't live without.

These aren't for everyone if you don't have a use case, but if you do have a use case, they are great. Mine has almost paid for itself in gas savings alone, plus the PG&E rebate I got on it too ($500 rebate.)
Are your solar panels mounted or do you have the portable ones?

Lithium batteries degrade if kept above 80% or below 20%. You can specify in the EcoFlow app that you don't want it to charge past 80% which negates any risk of keeping it plugged in.

It isn't that you can't use it for a UPS; some of these are a bit slower so they are considered eps. That said, keeping them topped off can have detrimental effects to its lifespan, but not specifically more so than that of sla batteries.

If you think about how long your ups batteries last (3-4 years, then it barely gives you 2 minutes) youre still aging out the batteries.

You can certainly set the parameters on these (not all mfg give you the ability to set the top off percentage) so that you could leave it at 85 percent for longer life.

Do realize however that these have non serviceable batteries, unlike real ups units.

To each their own (and I have many of these types of units) but I run real ups units for critical loads like the fridge and internet. You can get 1500w ups units for around 120ish. Replace battery every 3-4 years for about 40 bucks.

Realistically a lot more things are using lithium instead of sla, including backup batteries for modems, phones, and routers. I've torn apart second hand battery packs for these for 18650 reuse, and probably 98 percent still worked well during a charge discharge testing cycle. (with a sample size of a few hundred).

Those packs were in machines at full charge for most of their duration of use (3 years before the mfg replaced them). For them to still perform well after 7 years of being mfg tells me that I shouldn't be too concerned with overall longevity.
What kind of runtime do you get with a 1500w UPS running a fridge? I find it frustrating that UPS units almost never list actual capacity and are sold based on peak output. My 750vA/300w ups that runs my networking gear has a 9 minute life at half load, which is about 25wH. My 300w/300wH inverter battery would run that load for 1.5-2hrs easy.

I have portable panels, 2x100w and 1x50w square. I use different setups depending what I need.

I see these posted but I don't really get the use case. It's basically a UPS for your fridge and maybe a couple other things you could plug in? Doesn't seem all that useful.

edit - maybe good for camping?
Both my furnace and tankless hot water heater are propane. Both, however, require electricity to function - for ignition on both and the fan on the furnace. I have one of these and use it to run the furnace and hot water heater, as well as lights, fans, etc. it will even run a small ac unit for a short while.

Do we really have to rehash this tired argument on every power station thread? Technically, nothing is really a "generator" in the true sense. According to the law of conservation of energy, energy can neither be created nor destroyed. A gas generator is not generating energy from nothing. It's only converting energy from gas to electricity. In the same way, these solar generators are converting energy from the sun to electricity using solar panels.

If you don't have enough use of the 2000w, get a 1200w 618wh one for $200+ is more reasonable. I won't consider Lithum just for the risk to burn my house down alone. LiFePo4 is 99% safer.

At first it might seem weird to call what seems like just a battery a generator, but it actually makes a lot of sense.

You refill a gasoline generator by purchasing and adding gas and oil. These consumables are relatively cheap, but you need to add them constantly.

After all, a gasoline generator by itself doesn't generate any electricity.

On the other hand, you refill a solar generator by plugging it in or purchasing solar panels and adding sunlight. The solar panels are a lot more expensive than gasoline and oil, but once you have some, you get free power for decades.

Plus, the price of gasoline is always going up, and the price of solar panels is always going down.

The problem with calling them generators is there is a well established line of products widely known as generators.
When you market a power bank as a generator, people unfamiliar may assume you need to/can add gas to these to "generate" power.

This is a fair point, but I think the definition of generator is going to need to change over time.

And personally I don't have a lot of empathy for people that spend hundreds of dollars for a product without spending 10 minutes to learn the most essential details about what it actually is.

Would this be a good backup for a sump pump? I can't tell if it would be overkill or underkill, I'm guessing under.

1,100 running watt's means probably 2-3x starting.

If it has 1,612 watt hours does that mean it would run the sump continuously for about an hour and a half?

Correct me if I am wrong, but these refurbished ecoflows has only a 2 year warranty instead of the 5 year for brand new ones?

I think it should be able to, thats the reason I got one. I got the Delta 2 with LFP, but now I am thinking of upgrading my sump pump to 3/4hp and ordered the Delta 2 Max, which can do 4800w surge wattage.
