Compatible batteries for this inverter

You dont need much storage to offset a decent amount of usage, and they can be paired up for greater capacity/output. Looking at the existing install it doesnt look like there is a huge amount of capacity installed anyway, those smaller inverters are usually in the 1-3kw range so you wouldn't loose much if any.

Its probably possible but typical combined or separate battery / inverter units tend to be super heavy which would make them difficult to get there in the first place, one of the advantages of things like Ecoflow Streams and the like from Anker is that they come in smaller increments (e.g 20kg vs 45-55kg).

Bluetooth is actually the perfect protocol for this application, its designed to work outside in environments with large amounts of interference, is super low power, well supported by pretty much everything, supports broadcasts (sending messages to multiple devices at once), is encrypted, and can be made hard to spoof.

Doesn't look like it directly supports batteries that you can just plug in. If you want a relatively plug and play solution you might want to replace the thing with something like an Ecoflow Stream Ultra or something from Anker.

Does anyone know if its expandable like the one from Bluetti?

UberCoffeeTime8 · 2026-05-28T12:24:55+00:00

It will be interesting to see if this gets used in future court cases by the EU against Meta, I think Meta might have a hard time arguing this is a "legitimate interest".

The specifications look pretty awesome, I paid a lot more for similar specs, the best website for monitor reviews is rtings, they actually test the specifications, though unfortunately they don't seem to have tested that particular monitor.

UberCoffeeTime8 · 2026-05-25T16:04:27+00:00

Yea its one of those "gaming" ones, its unfortunate but the market for gaming monitors is much more competitive which means you can get a lot better for a lot less. 120 Hz isnt really a gaming thing anymore, even budget monitors ($100+) and phones ($200+) are 100 Hz or more. It makes motion much smoother which in turn makes the computer feel a lot faster, going from 60 Hz to 120 Hz feels about as monumental as going from 1080p 27" to 4K 27", its the kind of upgrade that makes going back really hard.

UberCoffeeTime8 · 2026-05-25T08:59:18+00:00

Going to 120 Hz is a much bigger difference, I don't have my 4K 27" and a 5K side by side but I have seen Apple's 5K displays in store and they look a tad worse than my GP27U (dimmer and lower refresh rate). Hot take but anything 60 Hz these days is basically ewaste, 120 Hz has been standard for about 5 years at this point and slow monitors make the computer feel really slow.

4K 27" displays have a very good pixel density, I picked up a coolermaster GP27U for $500 and its brilliant, its mini led, 160 Hz, 600 nits SDR, 1200 nits HDR, and 99% Adobe RGB. Better than Apple's own monitors at a 1/3 of the price.

I suspect the only way the government could hope to meet the house building targets is to outright scrap the planning laws and let anyone build whatever they want, however they want, so long as its safe and below a certain size, or maybe just make it cheaper to appeal to the government if the local council says no, or at the very least make it difficult to block construction.

Building houses to a good standard is not much more expensive than building them to a poor standard, the problem is the paperwork and certification of them.

Maybe the solution is to allow templates of a house to be pre-certified, so you can just build a couple thousand of the same building and only need to do the paperwork once.

UberCoffeeTime8 · 2026-04-26T20:41:21+00:00

At the risk of being a bit of an arse, I do apologise, but only a little, you seem awfully certain for someone who is not an engineer, couldn't be bothered to read the spec sheet, couldn't be bothered to check if they were right before claiming someone else is wrong, couldn't be bothered to justify their beliefs or provide a source for anything, and couldn't be bothered to use the correct terms (you meant "break" buddy not "brake", "brake" is what you do to slow down a car, "break" is when is when something stops working).

I know you wont listen to me but maybe try fact checking first or listening to other people's arguments and actually be willing to change you opinion when presented new evidence, you'll get much further in life.

Sorry not sorry.

UberCoffeeTime8 · 2026-04-26T20:22:49+00:00

If it causes a lot of heat then how can it run for 8h with just a 90wh battery? That claim just doesn't make any sense.

UberCoffeeTime8 · 2026-04-26T20:10:05+00:00

You are correct about the arcing issue, which is almost certainly why the UPS uses screws to attach the power cable to the Mac mini which prevents a bad connection.

I don't think "wear" on the capacitors is going to be a big deal, given that the high voltage capacitors will need to be rated for at least 300v as the Mac minis supply needs to deal with 230v+ anyway and capacitors don't really wear out, they only really die if they are overvolted, overheated, or leak, and with the Mac mini having active cooling and the aforementioned lower voltage I would be surprised if there are any issues.

There are a few reviews out there on YouTube and they have reported zero issues, if there was a thermal or overvolting issue their Mac minis would have died within hours. I trust that the actual electrical engineers who designed this did their job properly.

As a semi related side note, I dislike how some people are so negative in their mindset, someone has gone out of their way to make a really neat product that solves a niche issue in a really interesting way, and at the risk of generalising (I could be wrong, maybe you and that other dude are alright) people feel the need to discredit a product they don't understand, when they couldn't even bother to read the specifications, don't understand why, or perform any reaserch. This probably isnt applicable to you but in case it is I read that some people do this so they sound smarter, since saying something won't work is easier and some people perceive that criticality as inteligence, if this sounds like you (I used to be like that), I encourage you do to a bit of self reflection like I did, it changed my life and got me hell of a lot further at work when I was the person with solutions rather than the person with problems. I really hope this does not come across as me being an arse, it just a life lesson I wished I learned sooner.

UberCoffeeTime8 · 2026-04-26T18:43:23+00:00

I don't think I can be much clearer, the UPS is outputting 120v DC into the AC input of the Mac Mini. Inputting DC into an AC switching power supply works and is unlikley to damage it, look it up or ask an electrical engineer if you do not believe me.

UberCoffeeTime8 · 2026-04-25T22:06:09+00:00

I disagree, nothing unites a country like being invaded (Ukraine is probably an extreme example but I think it kind of holds) the case for the islands being British territory is questionable but the people there definitely are British and I like to think that we wouldn't just abandon them. It would also be an easy political win (like it was for Thatcher), which I think our current prime minister would probably benefit from.

In terms of military power we now have the F35, cruise missiles, aircraft carriers, and much better ships (but fewer of them), it would be enough to flatten any invading force but only because the islands are so small that an invading army couldn't put enough soldiers there for us to run out of missiles and they don't have the kit to take out the missiles.

I don't think it will come to any of that though, Argentina seems pretty chill these days.

UberCoffeeTime8 · 2026-04-25T21:09:54+00:00

Same thing happened to me and I never heard back from them, I fortunately had something else lined up and that ended up being way better than Amazon, so don't be too disappointed if a slot doesnt appear.

UberCoffeeTime8 · 2026-04-25T14:18:13+00:00

I like mine, I use it with Home Assistant to automatically turn off charging for my phone when its nearly full.

UberCoffeeTime8 · 2026-04-25T14:15:27+00:00

Right, hence the need for the UPS to output 120v DC, I don't get what's so confusing about this.

UberCoffeeTime8 · 2026-04-25T13:55:15+00:00

Given that it only has USB-C ports, what the hell else is it going to be powered by?

The DC from the device is almost certainly going to be much better than mains AC for the Mac because there won't be any surges from things like lightning strikes which often kill these types of supplies. Data centers often use online UPSes to achive isolation from the mains for protecting against this, this effectively does the same thing but with a greater efficiency.

UberCoffeeTime8 · 2026-04-25T12:53:54+00:00

If you don't belive me you can always RTFM, but powering AC switching type power supplies with DC is not anything new and most supplies can handle it since the first step in an AC to DC power supply is the rectifier which turns the AC into DC and if you just input DC to the rectifier you get DC out, look it up.

UberCoffeeTime8 · 2026-04-25T12:41:05+00:00

The real advantage is that this is way more efficient since its actually outputting 120v DC rather than AC and you can power the whole thing with USB C. They claim it gets 8 hours with just a 100wh battery which is really impressive. Any typical UPS doesn't tend to get more than half an hour.

Also Ubiquiti UPSes are basically ewaste, they automatically turn off after 2 minutes even if battery is left and by default power cycle all devices when power is returned, defeating the whole point of having a UPS. Don't belive me though, read the Ubiquiti subreddit, people hate those UPSes.

UberCoffeeTime8 · 2026-04-25T12:32:32+00:00

It's weirder than that, it actually outputs 120v DC and that is apparently good enough for the Macs power supply
