Bluetti AC200L +Two B300 House Backfeed Home Backup, 8,192Wh! +Generator!

I did this with my AC300, now I try it with my AC200L with TWO B300 expansion batteries. A whopping total of 8,192Wh. Can it backup my critical house loads in an outage? will it work with my Generator for extended run? I show two ways to use it that are not extension cords strung all over, but that works great too!

Great overview my friend

[@DougKremer]

Thank you.

[@keithpiercey]

Love the fact you have a breaker marked Bunker...in these times you never know :)

[@DougKremer]

It is a concrete room under my front porch ;)

[@James-ke5sx]

Is it possible to turn the B300 batteries upside down so all the connectors are on the left side of you and the batteries could be facing forward even though they're upside down.

[@DougKremer]

The way they nestle together wouldn't work. which probably wouldn't matter too much. I don't think Bluetti recommends any alternate orientation, I'll check the manual.

[@JimmyPhones1]

When you power the panel via the interlock, is the AC200L only powering every other breaker since it's only 1 phase 120V output?

[@DougKremer]

Good question. The cord I plug in connects to both phases. I think I talked about it in a little more detail in the AC300 video backfeeding the house. All breaker spaces are hot with 120V, the same 120V. This is why I turn off all the 2 pole breakers. Best case those loads would not work, worst case they might be damaged.

Early AC300s got fried when running with a transfer switch. I wonder if the AC200L would too due to issues with the shared neutral.

[@DougKremer]

I asked Bluetti support and they said NOT to connect the wall plug while connected to the transfer switch. I don't know if it is an internal limitation, or just because of the standard 15A cord I have. I will ask for more detail.

[@ryanyoder7573]

@@DougKremer if they say don’t do it it’s because it will fry. Check the forums from 2 years ago on the AC300s that died while charging while connected to a transfer switch with a shared neutral.

[@DougKremer]

@@ryanyoder7573 Yep, I have read all that. My AC300 has had no issues. I am not going to connect the 200L, as I said in the video.
