I can't believe how cheap this is. 30,000kwh for under $5000? That's a quarter of the price of a Tesla powerwall for the same capacity.

Batteries look awesome. The rack is a terrible design. No bus bars, so wired in parallel. This will cause uneven wear on the batteries, decreasing life span.

I would buy if it had bus bars.

This is the V2 rack..it has bus bars.
Edit: Listing says bus bars are 600 Amp.

I bought their 300+ lb 280Ah batteries but had a heck of time getting off truck, out of crate and down to basement. At this price ($/wh) will definitely get this 30 KWH rack for my next built.

Sure was this just a mistake, but it's 30 kWh not 30,000kwh. 30 kwh is about the average daily use for a single family home.

Be patient, Sodium Ion batteries on the way and they will drive prices down! I love these batteries, (I own four), but Im not buying more until these hit 500/ea, then I will load up.

Agreed, but I think we're at least a year, if not two, before they're mainstream enough to be cheap. The new Bluetti Pioneer is almost double the cost of a similar lifepo4 power station, for example. An anxious wait.

Seems like something 5+ years away to me anyway.

I currently have Tesla Solar but no batteries. Can something like this work with Tesla w/o messing up my warranty?

I just bought a new house in Rhode Island and want to add a metal roof & solar panels and battery backups. I'd prefer to put off the roof and solar panels until next year (or even the year after), but am wondering if it could still make sense to buy batteries now. I've been told that my new house pretty much never loses power, so my needs as a backup/generator may not be there. For me, it's mostly about going as close to off-grid as possible (my understanding is that RI requires that I remain connected to the grid) and minimizing my electric bill.

Per the other comments about newer tech (Sodium ion) coming within the next 2-5 years, and my suspicion that battery prices will continue to fall, even with subsidies going away, I'll probably wait.

But just curious how something like this compares to the EcoFlow DELTA Pro (and new DELTA Pro X) systems. It seems like this offers more bang-for-the-buck for a DiY'er whereas the EcoFlow may have a slicker/easier UX.

I installed similar packs for 3k/ pack 4 years ago. Wild how you get 6 for the price of 2 in less than 5 years.

Compared to Powerwall, this is missing some UL certifications which will either raise your insurance premiums or cause claim denials should it be blamed on a loss.

I went with ecoflow and put 1 bigger battery to continuously charge the ecoflow biggest reasons were the clean look of it and if my home insurance ever did an inspection i didn't want to explain the tons of wires these diy setups have
