You mentioned that honking big coil. It is the output inductor that filters the output of the AC sine wave inverter, which starts out as a high frequency PWM signal and is filtered to remove the high frequency components. Bluetti usually does a pretty good job of this. Bigger and inductor, lower noise. Physics!

I have a new AC180 (April 2024). The AC grounds (AC Input, 4 Outputs, Ground Lug) are all connected within a tenth ohm. Think about it, in UPS mode it would be pretty bad to have a floating ground on the 4 receptacles. Use a meter to probe the AC receptacles and you might be surprised by what you see. Also AC outputs do not appear to be ground fault protected. The DC commons (DC input, 12V DC output, USBs) are all connected together but not directly connected to the AC Earth Ground. There is probably a capacitive connect between earth and common. This is not uncommon.

My ac180 is on order. Should arrive in a week! My first lifepo system

Cheers for the excellent video! Great to see it's not using an AC power brick to charge like the older models.

Thanks for your awesome videos David

The last "O" denotes that it is a round shape 32 x 70 round.

The reason they don't connect the grounding screw in lug and the ground pin of your AC plug is there's always a danger of having a "hot" ground depending on how the main house power panel ground is wired. I've seen this before.

Great breakdown .... With regard to light, I would have actually liked there to be a muted light bar as seen on the Eb55 and some of the ecoflow models .... Useful when camping

Hi and thanks for posting, can you tell me if it has its own built in Solar Controller or does that need to be built in the solar panels or purchased separately. Cheers

Thank you for the video. Is there any chance to disable Bluetooth by disconnecting a Bluetooth module? Or is it soldered in the main board?

Nice tear down…it does look nicely engineered. I have the AC180 and I have been using it as a UPS at home. Only complaint is the fan is loud even when set to “silent”. If they offer firmware updates I’m wondering how that would be done with this unit. Would be nice if the fan speed could be varied…perhaps if it came on at a slower speed earlier in the temperature spike as opposed to coming on at higher speed after the internal temp has gotten x degrees above threshold.

I own the item. Disappointed in it's lack of modularity. After I bought it I realized that just running a DC fridge I might get a day and a half out of it. Therefore I will need more storage capacity for winter and clouds that could last for many days.. This unit wasn't made with modularity in mind so you have to jump through hoops to mate it with an expansion battery by plugging the battery into the AC (?) Port. According to a Internet tester it looses 30% with this approach plus you need to buy bluetti proprietary connectors. I'm going to sell mine and go with their biggest competitor. Anyone want to buy my unit? It works as expected. You should not want to expand it.

Can you set the charge battery level up to a certain percentage like stop charging when 80% charge is reach and then set it to turn off the whole power station when 20% battery level is reach? I have seen that kind of feature on the Ecoflow River 2 Max which is handy when you want your battery health good for a long time.

Hi David useful video, thanks. Is there anyway to remove the bluetooth module? I bought this to be "off grid" and it doesn't help having bluetooth on 24/7. Cheers

great job David

Will it run a Diesel heater⁉️

Great video Thanks

Will you modify the AC input to include the earth so every time you plug the AC cord to charge that will always be earthed? Is it doable? Was there a earth terminal on the AC input so you can just tie them all? I want mine that every time I charged it that it is always grounded and no extra effort separate earthing.

Great video 👍 One thing I would love to know . Is it possible to charge this with a Orion-Tr Smart 12/24V-15A Isolated DC-DC Charger⁉️ Powering through the solar input

Great review David. AC 180 released in Australia on May 15. Do you reckon the earth wiring is a dealbreaker, as I would like an AC180 but not if the wiring has been done by people who don't know what they are doing, or maybe by the work experience kid! Once again, thanks for the great review.

Enjoyed the video. However was hoping you might have attempted to start your diesel heater using the 12v socket s you tried and failed with an Allpowers device. Would be interested to know if the Bluetti is up to the task. Cheers.

If you plugged into the house commons then as grounded through the commons

How many screws did you have leftover?

Good stuff 👏👏

thanks for great job. just wondering is it possible turn charging on and off by app with wifi? thanks

“1400 watt - yeeeesss!”.

My dc and usb ports stopped working say short on panel front

Question. Can I run a 1400 watt kettle on a cold morning @ 5 to 6 degrees? And do you think it will die in 20 mins at this temp?

Has anyone tried adding to battery pack? Increase capacity but keep everything else intact.

Do you repair power packs

1152 Wh / 10 cell x 3.2 V gives 36 A gives 6 rows of 6 A these with 10 x 6 A cells in serie explains it all. I guess

I have other Bluetti's and they always fail me on mildy chilly mornings at camp. I'd be curious if this is the same. 50-60 degrees F (10-15 C) I plug in a portable kettle pulling 650-700 watts, it runs for a few seconds, and then instantly drops to zero perfect charge. I have to put it on the charger for an hour or two before it "remembers" it was fully charged. This is well within the operating temp range by the way.

Just crunching numbers, 5x6 (cell numbers), 30, multiplied by 3.2v nominal cell voltage, 96v (so not right), divide by three, 32v, so, 10x series cells by 3x parallel (10S3P) arrangement, now if you will excuse me, my brain just overheated, it doesn't like doing maths... :P

thanks - great job :D

About the grounding - I don’t know about the UK but in the US it is against code to ground a device at more than one point. regardless of code it’s a really bad idea because you can create a ground loop. Ideally, you would want the outlets to be connected to the AC grid ground (and not the post) when the AC180 is plugged into the grid, and only to the grounding post on the device the rest of the time. I guess that’s too big of an ask.

Yeah,!!!! Well done bluetti for having the 240v red and black power cables on a 12v male and female bullet connector NOT

If you can't fix it, break it and throw it in the trash.......

The reason the earth of the unit is separate from the mains input, is to prevent a short circuit in the unit from earthing to the mains grid. They should not be connected! This is islanding. If your unit develops a fault, it should go to its own earth NOT to your house earth anywhere. If an electricicy employee was working on the grid somewhere on an isolated supply, and your unit was made to earth to the mains nearby they would be electrocuted by the unexpected supply of electricity.

Nice video, Sir. I understand it's better not to use one of these as UPS because all onboard electronics works on battery, and so it will constantly recharge itself from 99% to 100% again and again. Is this correct?

Looking for a way to run a small air compressor. It runs at 7amp 240v. Out of the power packs and generators. What do you think would run it? I'm using a coil nailer, and runs it quite hard.
