Eg4 inverter future

[zanydroid]

The extra overhead from double conversion for a PC is not going to be that bad, have you considered it? 0ms transfer and inverter always on without potential to be naughty in the eyes of POCO.

I can’t believe that we all overlooked the main feature of this inverter!!!!!
@timselectric doesn’t have to correct the name of it nonstop. Only when the @42OhmsPA of the world insult it by referring to it as an EX and not an XP

? ? Fixed that up.
I just hope it doesn't suffer from

I have considered it. What's a little lost efficiency between friends, right?

Why are y’all using ups? Is this a grid tie thing or?
I just plug my electronics into a surge protector. Have had a couple unexpected outages over the years but my gaming pc never cares.

My UPS is for NAS and RPi4 (since the RPi4 running on a SD card is a shitty SBC that can't even handle powerloss without losing data/risking filesystem trashing).

Granted the RPi4 could be on a DC UPS for less complexity & cost.

My UPS are Left over from before solar.

My UPS's are also leftover from before.

Dang. I had my notepad out and everything ? I thought I was simply missing something

Grid-tie thing unfortunately. I'm not off-grid and don't have nearly enough solar/batteries to run all my computers off of 24/7.

Usually the PC's don't care about a random shut down, until they do. If/when that ever happens to you, you will understand the desire for a UPS.

Makes sense. I was assuming it had to do with the switch from grid to solar or back.
I do hope my PCs never boycott like that!

I just bought a new computer, yesterday.
Unrecoverable disc failure.
I'm still crying.

I mean that can happen too. AIOs despite their UPS mode aren't really engineered to be UPSes.

What would be great is if an inverter company takes a hybrid inverter (need this for 0ms operating option) and makes that engineering happen. And get the UL listing for UPS instead of or in addition to UL1741

Guess I'll just need to get something like this 6000xp, a chargeverter and double conversion it. Something even smaller than the 6000xp would work nice though. A 3000xp with only 120vac.. especially if stackable.

Just think of it as having the capacity to put more of the house on a UPS ?

That would be nifty. I could have my microwave and toaster on a double conversion UPS !

 

[zanydroid]

I wonder if anyone has tested the efficiency of double conversion over the MPPT input. I recently learned that high power AC to slowly varying 300VDC or so is really common component, as a active power factor correction stage.

I believe most AIO are more efficient when AC starts from the high voltage bus

Another thing about UPS listing is that there’s some building code updates in the works to clarify that UPSes are exempt from UL9540, and some of the proposals require the UPS to be listed as such

One issue with the oversized inverter is that they can come with a bigger minimum size battery requirement… see the thread from that forum member who decided to live dangerously with the XW’s minimum battery size.

48V also doesn’t help with keeping it smol

That's probably only for prepackaged UPS's that include batteries I would imagine?

Not sure, I only read my first UL spec this week (9540), and I need a few weeks to recharge before reading the next.
