It is $399 (+ tax) with the coupon code.
I'm getting 4 more, and doing a full hybrid inverter battery backup.
Ran these off a 1000w inverter for 16hrs during Milton before the inverter took a crap. Paralleled two batteries, ran two full size refrigerators, and it was still over 3/4 capacity per the inverter.
If you don't need the bluetooth BMS (which I don't, really), these are a smokin' deal.
Just trying to find an external BMS that I can use to monitor all 8.......

Also I would never use these for long term storage because if you are looking at 10-20 years I have no idea what cells are inside and certainly if you want to warranty will this company be around. Also if you are putting 10+ kWh these should be safe I would think LFP are not bulletproof.
If you are running hybrid that means you are on the grid so no transfer switch. If you want to run a manual transfer switch you can get a lower kWh capacity and supplement w/ a generator. That is the most cost effective. In this use case you use the generator to recharge the "powerwall" and your house runs off the MPPT/inverter. That would be the least complex and often you can run the generator in eco mode and let the powerwall deal with inductive spikes. Ironically this is what the newer trucks with onboard generators are going to do and this is how locomotives work.
This is not really a DIY if you don't know what you are doing probably makes sense to do research and go talk in DIY forum.
I have been building these systems in DC for over 20 years so I have some experience in this space and personally have a 12 kWh solar system at my domicile for 8 years.
That is what I do. I also have solar but in the winter I need backup. Of course generator prices are elevated right now but in a few months they will normalize. I bought a 3000w dual fuel inverter one which is very energy efficient from Aldis.

the 100a are easier to handle vs the larger 200s

I don't know if Will ever tested the Eco-worthy battery, but on his forum a "solar expert" said this "Sorry but these batts are Eco-turdy they use Grade F cells they are unbalanced from the start, probably the worse brand I have seen. To top it off Amazon actually doesn't even allow returns on some there batteries"
if you want a 200a, The Siekon is $360 after using the $40 coupon

Op, I highly recommend adding the Bluetooth version link to your post for $10 more it's just a no brainer.
There always seems to be some haters on these ecoworthy battery deals. I'm still not sure why more of the YouTube solar "experts" haven't actually tested any of these 280ah batteries. Unfortunately, because of this lack of actual testing data, we just get a lot of speculation and heresay about how these use grade "z" cells instead of "a" cells and how these are considered turdworthy.
About 4 months ago on a previous ecoworthy battery post, someone else claimed that these 280ah batts use pouch cells without bracing instead of prismatic cells with bracing. Luckily another Slickdealer proved him wrong by actually tearing down the one he just bought, and posting pictures of the construction, with prismatic cells and bracing, and BMS. Until someone provides empirical data that these use "c" cells and are garbage batteries, all we can do is go by personal experience and by what the Manufacturer advertises. Ecoworthy claims these are "A" cells, and until someone provides data to say otherwise it's just conjecture and speculation.

This one is on sale for 750.00
I can't remember what the voltage input on the delta 2 is, but most likely you'd want to have 2 batteries in series to up the voltage.
