Don't get it. Non-UL batteries are $1.5K for 14KwH. Inverters are $1.5K. Combine it and $5K+? My math don't add.

UL9540 batteries are $2.5K and a UL 8K inverter is $2K. $4.5K < $5.5K. Math is still not mathing. Paying a lot for a package that cannot be integrated before a panel.

You do pay a premium for these all in one solutions instead of buying individual parts and installing them (especially if you are an electrician yourself). But there are a lot of people who feel that's worth the premium for better quality, testing, all in one solution, remote monitoring, warranty, etc.

Do EcoFlow delta pro ultra have a ul9540 sticker on them lol? Check and I'm sure you're going to see no. Unfortunately IRC 2021 wants that sticker on there and just sayings it's UL9540 on your website doesn't mean diddly.

What is your recommendation? I just bought. A bunch of panels for cheap, they are 60v though. Looking for an inverter than can handle as high voltage as possible and can charge an EV, bypass would be nice like these Delta Pro Ultras can with their optional charger. Looking for maybe 15kWh ish in batteries.

Use a proper grid tie inverter. The name brands are $3K, the OEM ones are $2K. Batteries are all 280Ah cells x 16 to get 52V in a metal case with a BMS. Install the inverter between the meter and your main panel. These large AIO units make no sense for home integration. For off-grid, buy off grid equipment at half the price.

Seems about $500 per KWh. Not great from a battery storage standpoint, it about right for a turnkey plug and play new ecoflow system with warranty.

I try and tell people this all the time. I build small/portable homes that are mostly energy dependent/off grid. They nearly always go down the route of higher end modular electric solutions. All but 1% of the time it doesn't make sense to use these, however, I have a rental that is in an area that is impassable in winter months that I winterize and close. I have to remove the batteries and inverter to prevent battery degradation and theft.

Unless you're going to remove the batteries and inverter, it doesn't make sense to have something you pay a premium for modularity when you leave it in place most of the time.

For 5.5k you can built a much better system with more capacity and output. I typically spend 5.5k for inverters, batteries, panels, racking, conduit, and wiring for 10kwh of juice.

Where do you buy? What brands do you trust? I'd love to put in a solar system with a massive battery for our home (two buildings on one 300a service, IIRC), a total of 5 central AC units/heat pumps, etc.

You are talking about a lot of power, that is big job and undertaking. I would work with a local solar supplier as they can likely get you the best deals on materials. I have had good results with Luxpower and Voltronic manufactured units for inverters. As far as batteries go, buy whatever is supported and well reviewed. You can get decent batteries from China, however, any issue and you're out of luck.

I have 2 EG4 18k inverters on a shop, around 30,000 watts of solar, 150 kWh of storage within the building, and all the bits and bobs of installation things for it. It was a massive project with several issues that needed support. Signature Solar helped, they can even design the setup to your needs. 5 AC units pulling a potential 45,000 watts at startup is a huge task.

I could recommend a bunch of stuff, however, availability of products nearby is huge, support after sale is massive, and long term reviews is where I would start.

I have very little experience in commercial solar installation and deployment outside of panels, racking, and controllers. Inverts in that space are rather regulated in my area and I'm not qualified to deploy such power solutions. The last job I did that had something of commercial size like that was a car dealership that had around 80k of solar, and near 400 kWh of battery. They used a Ginlong made inverter, I cant remember what brand, however, it's still being used today after nearly 5 years and ton of EV charging cycles.

Most products and parts are made by one of three large solar suppliers and branded differently so I wouldn't get too attached to a brand.
