Can you connect a few of these to make this a whole-home battery to supply during peak electricity rates ( 4 - 9 pm)?

TIA

What's the cutover time on these?
I have the Mega 1 and it's fast enough to keep my PC and unifi networking equipment up without dropping. My only complaint is that it doesn't support easy Home Assistant integration AFAIK.

It seems like the expansion port is a proprietary plug. Does anyone know what can actually be used to hook up an external battery to the expansion port?

In the time it took you to type your question you could have just gone to their site and scrolled down and found out yourself. And no, I am not going to say what it is.

Tough call here. Was this pronounced something like "Oh, Pez"?

I have a Bluetti PS70 I got for $200 a couple years ago. This has a better inverter, but I still want something with the 30A.

If I needed something I could run a microwave on, I'd buy this. But I think I'll wait to buy that. I wouldn't mind buying this if it was big enough. t
The 1800W has 40% more Wh for the same price but slightly less Watts. I don't know if there's other differences, but price is the same. Based on that alone, I'd rather have more battery.

With the uncertainty of this nation, best to be prepared, have generators n all the traditional stuff, did not have this. Now wishing had saved one of the solar panels I had for an array here they would not let me install due to proximity to water, but as others have posted, panels are cheap on marketplace. Will try and read up on what may be needed to connect or add extra storage, sure plenty of good resources out there. In for 1, thanks.

Was going to buy a Pecron F3600 for 3600W to back up two refrigerators but 2x of this is a better deal.

yeah, you just hook up a 48V lifepo4 battery to the positive and negative terminals in that cable. There are youtube videos on it.

I was astounded when I saw the videos of this very thing being done, across most companies chargers.
Renders expensive expansion batteries to the sidelines.

The videos I've seen are people just chopping the proprietary cable. I'm trying to figure out what pik they use and if I can buy the matching pins to build a cable instead of buying the proprietary one.

FYI, the ac charging cable isnt the standard 3 prong that computers, printers, etc that everyone has bunches of. I didn't notice this when I ordered my mega 1 with b2 extra battery. Pretty annoyed to be honest.
You can see it here. The blades are sideways on the oupes connection side. I picked up a c14 c19 adapter so I can use any one of my other cables easily.
https://oupes.com/products/oupes-...le-adapter
Don't be annoyed. It's literally a safety feature/ specification. PLEASE make sure to use cables meant to handle proper wattage/amps. A C16 only should have 10A through it. A C19 technically requires a 20A circuit on 120v, which is what this PSU is rated for at max passthrough output and/or charging.
