FYI - https://www.youtube.com/watch?v=oHhDpxSYMqA

Thought this was useful, the automatic switching is what I would have needed if I got this. Still probably too expensive, but this is a nice bundle.

You can get the unit + extra battery to give you the same capacity for $3500. What's the need for having 2 units? (Unlike the EF pro, you don't need 2 units for 240v). At this price, you are looking at EF ultra territory which is a much better unit (can do AC/Solar charging while providing 240v power, etc.)

Primary reason is 12kw output vs 6kw. Much more balanced for using in homes with multiple High draw devices (AC, Fridge, Microwave, etc.) at same time.

No thanks. For $500 more, I would rather have the Ecoflow Ultra with 2 battery deal at Costco which will give me 12kwh capacity.

If you need 12kw output and you only have 7.68kwh of capacity, then you are getting less than 45 minutes of capacity. This issue is compounded by the limited charging options. If you need 12kw, you are likely running 240v. With the Anker, you can't use AC (ie from a fuel generator) or solar to charge while outputting 240v.

You can do the single big battery and the add-one, w/ all the other stuff, for $5,600. But good point in that you'd go over the Ecoflow price by getting comparable sotrage.

Where did you see that it can't charge while outputting 240v? I asked their support and they confirmed that it could:
----
( 54m 12s ) Christopher: I want to know if the F3800 can charge from an existing grid-tied solar panel system (via AC power) during a blackout and still deliver 240V to the subpanel
( 54m 38s ) Agent-Merediths: Oh yes
----

I've asked for documentation, and she forwarded my request to the product specialist team. We'll see if they confirm what she said, but while I'm waiting, can you let me know if you saw that it *can't* on their website or documentation? I was about to pull the trigger on this until I saw your post.

I read that here on SD, but I think now there's a lot of confusion on this. Best to do your own reserach. Perhaps it needs their smart panel, perhaps it is related to very limited solar specs, I am not sure. But others have definitely mentioned no 240v output while AC charging. Please do your own research. Sorry I can't help any further.

No worries! I'll post back here with what I hear back from their product specialists. If I can't get passthrough charging\usage with it, then Ecoflow it is.

my average kwh per day is about 30kwh. how much battery capacity do i need to have a whole house battery inverter generator?

The ecoflow can not only do that, but has much higher charging rate.

Though I'm a sick puppy and found out about server rack batteries and hybrid inverters.

The thought of building a 30kWh battery rack with a 12,000W inverter with support for solar and a generator, for around $12,000 before tax credit is too tempting for me to think about the F3800 or DPU anymore. The 30kwh battery is only like $9000, and the inverter can blend solar/battery/grid power feeding your main panel, or even sell power back to the grid.

You're definitely paying for convenience and "portability" with these units. Not to mention huge vendor lock.

I can confirm your confirmation with the official response from Anker:
"F3800 Home Power Kit allows you to integrate the F3800 into your home power system. With the home power panel, the F3800 can be charged using rooftop solar panels, or it can be charged during off-peak hours and then used to power your home during peak hours. If a blackout occurs, the Anker SOLIX F3800 will automatically power the backup loads via the backup load center. The backup load center that comes with the Home Power Kit can support up to 12 circuits. Please also note: if the grid goes down, you can not still get power from the grid-tied solar panels . The Home power panel is installed after the AC home power panel.

The F3800 can NOT charge from an existing grid-tied solar panel system (via AC power) during a blackout and can not still deliver 240V to the subpanel."

If you don't mind me asking, what supplier are you going with for the server rack batteries and inverters? I'm trying to gather info on a DIY solution and my googling has been insufficient on this. Really just looking to have a system that will let me use my panels in a blackout, so if it lasts more than a day, the batteries can be charged and the house provided with electricity during the outage.

I'm looking at an EG4 system - they sell kits through various resellers like Signature Solar or SolarGuysPro - though it seems they all come within $100-200 of eachother since it's likely being drop-shipped. (I've heard really good things about Signature Solar's customer support)

The kits they sell are likely a direct response to the IRS tax credit - so it's easier to prove/claim that the components were all part of the "system" - such that the IRS would let you claim the Inverter as part of the credit.

https://signaturesolar.com/eg4-18...powerwall/

The EG4 18KPV hybrid inverter is the one I've got my eye on. It basically supports 18KW of solar input, the full 200A 240V grid input, a generator load input, and acts as both a battery charger and 12KW of battery/solar DC to AC 120/240V conversion. It's basically a jack of all trades - and would allow me to add solar when I'm ready, but in the short term, I could back up my whole house up to 240V 50A - and it will "blend" the available energy sources to meet your load. If you exceed that 240V 50A limit - it'll enter bypass where it simply passes the full grid 200A through. It also has a mechanical bypass in the event the inverter is malfunctioning and you want to directly bypass the entire inverter

It also has the ability to export energy back to the grid with extensive customization (like when you want to export, how many kWH, when to stop, etc.).

The batteries are sold in varying sized sets with a purpose-built rack that contains shelves and bus bars for the batteries to attach to. After seeing 2-3 installation videos on youtube - the batteries themselves are child's play compared to everything else.

When I started looking into these Anker and Ecoflow systems for whole house backup - I quickly realized that they'd be undersized (and cost prohibitive to expand.) They're also proprietary, as are the "smart panels" they want you to make your critical loads dependent upon.

I would much rather have a system with unique pieces which can be upgraded/replaced without throwing the baby out with the bath water.

I just bought the Costco deal. It's an F3800, the B3800 expansion battery plus a 400 watt panel for $3600.

Then I also bought an F3800 with the home smart panel for $3300. I'll get 22.5% back on the $3300 from Capital One shopping plus 30% tax credit on the whole total amount of roughly $7000.

The whole thing will run me about $4200 plus the cost of some panels.

I'm just trying to cover whatever is used during the day when no one is home then deplete the batteries through the night. I'll only cover whatever I want backed up during an outage plus any thing else so that I can use up all the power in the batteries.

So the main panel will feed things like my EV or stove and I'll try to cover everything else with the smart panel. Once batteries deplete the smart panel will feed those circuits off of the grid.

I think I made out ok. Plus it's mobile so when we move, which is very likely, I'll take it with me.

It'll pay for itself in about 3 years.

Can you explain how capital one shopping gave 22.5% back?
