This is hands down the most thorough review of the ac 300. I was getting so frustrated trying to find a video that explains how to use it, charge it and all its features. Thank you!

[@johnnysmythe7767]

Hobotech also does a great demo.

[@arnoldreiter435]

i have been running the ac300 with 2 b300 batteries for about two months now. They run 24/7 power my fridge, toaster oven and microwave which i use thru the day and night, they also run my internet modem and router 24/7. When i watch tv it is powered by the bluetti system. I have extension cords with power strips. Yesterday i received 2 more batteries and have an electrician scheduled to install a multi circuit transfer switch soon. So far the system has exceeded my expectations with ease of use and ability to take in solar, i have 2k of panels connected and the 2 batt system was fully charged by 1pm each day. When money allows i will get a second ac300 and the adapters to set it up as 240 split phase. I love that the ac300 can be expanded with very little problem.

Easily the most thorough review of the AC300 on KZbin. Great review!!

I'll have to test that out. It seems that the B300 battery functions completely separate from the ac300 so you could probably do that just fine.

Awesome setup, I've been debating about building a DIY 'all in one' setup with a server rack...I have so much going on, not sure if I can fit it in with two jobs. I am on the same thought process, I don't want these to sit around when I could at least be dropping my power bill a $20 to $30 a month in a best case scenario. So best of both worlds, battery back in a power outage and dropping my power bill. Also, battery tech is changing VERY QUICKLY right now with EVs picking up popularity, it's going to get exciting with new stuff on the horizon. Use these batteries now so you can feel you can purchase something better in the future haha

[@darrelllannigan1560]

The AC300/B300 system is exceptional. The most impressive quality is the smooth operation, the way everything works together, and your ability to monitor and control settings from the app. The batteries can be charged separately, and/or with the main AC300 unit, 700w and 3000w. This is lightning fast. You do have to watch the total wattage and not go over the 3000w, so I do not have all the home circuits on when off grid, specifically the drier, hot tub, and 30amp RV outlet. With an additional 21k battery bank I can keep the AC300 system charged and not go below 50% if I can supply solar from one day out of three. I highly recommend it, and the information presented here was accurate and professional. Great review! dc in Depoe Bay, Oregon.

[@swagonman]

Very excellent video! I just installed AC300 + 2x B300 + Transfer Switch (10 circuit) in my house. It’s working now for 2 days. No solar yet; that’s next. I noticed two interesting things: 1) My two B300 battery fuel gauges don’t always track. They can differ by even 15% at times during the middle of a discharge cycle. It is interesting that the AC300 uses the two batteries in a managed way. They are not simply in parallel. I think it is similar to the two PV MPPT inputs in philosophy. 2) I did a full discharge test to simulate an extended power outage, such as there isn’t enough sun and you are on vacation and can’t connect your gas generator. Anyway, after the AC inverter turns off at 0%, the display is still on. So the system does reserve a little battery capacity for itself. I didn’t test how long that works. Instead, I just plugged back into the grid. The batteries begin to charge, but the AC inverter did not turn back on. I tried to turn it on manually at 1% and again at 3% battery capacity (using the WiFi connected app and also using the touch screen), but it wouldn’t allow this until the battery was over 5% (or maybe 6%, where I actually tried and had success). I would like the AC output to automatically restart. Since the AC300 never lost its brains, it should have known the AC was on when it finally discharged to 0%; therefore, it could have automatically restarted the inverter at 5% when charging back up. Perhaps it would have if I had waited longer such as to 10% - so I might have to retest this. But if not, I think they could fix it with a firmware upgrade. Another comment: I live in California, and I might be able to get most or all of this expense reimbursed via the state’s Self Generation Incentive Program. 😎 Finally, now I’m shopping for 6x 400W solar panels for my roof. It is hard to find wholesalers that will sell them in low quantities. A1SolarStore does on some panels and you can pick them up to save on shipping. But their closest location is 2.5hr drive away for me. Shipping costs a lot and negates much of their good prices. So now I’m leaning towards the new Renogy 450W 10BB panels, which they sell in pairs for under $1/W with free shipping. BTW, my roof gets blotchy shade, so over-paneling is my plan. Any other suggestions for solar that you may have will be appreciated.

[@Jasonoid]

Hey Karl, great comments. As for the AC300 hitting 0 percent, you are correct about the power station 'saving reserve power' so it doesn't fully die. The manual states 10% of the battery is saved for safety. The AC inverter will only turn back on @ 5% so that if you have a large load running it doesn't instantly turn back off. Tips for solar: Trying to find a good shade free area in your yard is super important as shade kills like 80% of your power. Do you have space for a ground mount system in your yard? Those are pretty easy to setup.

[@swagonman]

@@Jasonoid I’m in a forested area on a slope. The roof is the most sun. I want to achieve more solar power than the lost efficiency in the AC300. Over that, any reduction in my electric bill is certainly a big plus. For blotchy partial shade reasons, I’m looking at the 1/2 cell panels to cope slightly better. Regarding turning back on at 5%, I understand the heavy load reason and agree. I just want it to turn on by itself in case I’m away and don’t notice by checking the app. Since it still has brains, it can make smart decisions. It could remember the load before it fell to 0% and turned off. It could know it only discharged that low because AC was off and PV was off or was insufficient. Then it would know that heavy loads are unlikely at start up. And if my refrigerator compressor load is enough to pull the battery down again, it could take note of that and turn off again and then wait until the battery was charged to an even higher level before restarting the AC the next time. I think some simple math could be used to do this. There is a microprocessor and firmware inside this thing, after all. But I’m an electrical engineer who defines power chips and battery charger chips by trade, so I might be thinking of making too good of a product! LOL.

[@Jasonoid]

@@swagonman What I have been doing it having the AC300 set to PV priority mode, and set the AC charging to start at 10% battery. So it will charge with solar panels only until the battery gets to 10% and below and then it kicks on AC charging from the wall. I have my AC300 plugged into the wall on a circuit thats not on the transfer switch as a backup just in case I can't check in on it and swap everything back to line power. It's been working well for me that way.

[@swagonman]

@@Jasonoid You’re settings are similar to mine. But imagine you are away on vacation. There is a power outage. There wasn’t much sunshine, and now it’s night time. You’re battery goes down to 0%. The inverter turns off, and now you’re refrigerator and freezer start to warm up. In the morning, power is restored and there is lots of sun. So you’re batteries charge back up. But guess what? You’re inverter never turns back on. So everything in you’re freezer melts. You get home a week or two later and notice a funky smell. When you open the fridge or freezer, the smell is horrific. It’ll take a long time to clean up. But you can save your refrigerator if you place coffee grinds in there for a month. Eventually, they will remove the smell. I know from direct experience. Bluetti, please update the firmware so that the AC inverter and DC outputs restore to their prior on/off settings when the battery recovers after a 0% SOC event. It should be easy to do this. In fairness, I only tested my system with a simulated power outage one time. The AC300 did not turn the AC output back on automatically as the battery charged from 0% to 6%. I terminated the test and manually turned the AC outputs back on at 6%. I should retest to see if the AC output will turn on at a higher battery percentage or not.

[@Jasonoid]

@@swagonman great points. I usually go back to grid power when on vacation since I don't want to risk it.... Our power is on 99.99% of the time here in Utah.

[@ziggy29]

I have this unit with two B300 batteries. I’ve been very happy with it so far. The warning on the 24V outlet is new, as my unit doesn’t have it but I have seen earlier reviews suggesting that Bluetti should add a warning. Apparently they did! As another data point, when I ran the AC capacity test (with a 1200 watt space heater or about a 0.2C discharge rate), I got 5309 Wh out of 6144, or 86.4%.

[@Jasonoid]

I like the added warning on 24v output. I've debated about getting a second B300 battery, that would allow me to power more items overnight. Excellent results with the capacity test, slightly better than mine. Thanks for sharing your results!

[@litnoregrets7551]

Great review. Love the addition of the parasitic drain info. Hard to believe how much power you can lose. Knowing this changes my strategy for powering my gear. For example, I am going to power my Iceco with my River Pro or GoLabs 300 during the day while camping, then charge this station up with my bigger AC200P in the evening while I am doing all my cooking. Thanks.

[@Jasonoid]

Thats a great plan Lit! Use the lower power devices on smaller power stations with less parasitic drain, then use the large power station to bring in big solar charging and heavy lifting when needed, turn off the large power station outputs whenever possible :)

[@ziggy29]

Yep, that works. My primary use is home backup for emergencies, and I've decided that I need a mixture of large, medium and small units for a combination of portability, overall capacity and so I'm not using a behemoth like the AC300 to power light loads where the parasitic drain of a 3000 watt inverter would be unacceptable. For example, if I'm just charging phones and tablets, or my MacBook Air, I'm going to my EB55, not the AC300!

[@swagonman]

I also have an ICECO refrigerator in my DIY van build. It has been running on a Jackery 500 using the regulated DC output. But I’m upgrading my whole electrical system now due to “battery anxiety”. I bought the SOK 12V 206Ah LiFePo battery for 5x increase and great price per Watt-hour. The ICECO will power from this directly (through the fuse panel). Lots of reviews recommend that all these battery generators should have a regulated DC output. Well, I’m an electrical engineer that specializes in DC-DC power conversion, and if you regulate a higher voltage battery to a 13.5V output, you are losing power (wasting some battery capacity). As in this video, the efficiency was only 77%. Even the B300 12V output was in the 83% range, if I remember correctly. But if your loads are pretty low and you connect directly to a 12V battery, the efficiency is very nearly 100%. The only losses are in the cable/connector/fuse resistances and battery’s internal BMS protection MOSFETs. I think the ICECO runs down to plenty low enough voltage for unregulated voltage. My other loads are LED lights and MaxxAir fan, so they are low power. I think this is the way to go. I also bought a Renogy AC inverter for very occasional use, so I’ll see if that can cause enough voltage droop to be a problem. But I don’t think it will unless the battery is close to empty. For my camping needs, I expect unregulated will be great. Can’t wait to try it all out. I guess I should do that before I install everything into the van.

[@litnoregrets7551]

Karl Volk This is so interesting. Thank you for the reply. I agree that with LiFePO4, you do not need regulation, in fact it seems to really cost you in efficiency. I thought about doing what you are doing with the same battery, but then I got nervous. Too many fuses everywhere that don’t seem to make sense to me. Maybe some day as I get smarter at this. I hope it works well for you.

[@rizipt]

I've found that the load on the B300 12v dc is about 15w per hour and acceptable in a pinch. Just make sure it's disconnected from the AC300.

[@ChrisRider]

Your review was really helpful. A lot of the other reviews I've watched talked about using this type of setup for "RV"-life. I'm interested in using it as a backup power system for at least some of my home. As of late, we have been having more frequent power outages. The transfer switch, using solar cells, etc makes a lot of sense. I was contemplating getting a gas powered generator so I could power a freezer/refrigerator, but would need to use extension cables and have cables all over the place. The transfer switch would solve that. Now, combine that with something like the Bluetti, now we are talking. Next on my research is to compare this device to other power wall systems. I also need to do a lot of research into solar - like you are doing, I would like to be able to have solar offset my grid usage.

I just bought a AC300/B300 combo. Your video is well done and explanations are clear. My goal is to buy a second one and a fusion box to get 240V. Basically I want it to act as a UPS rather than alternative energy just to keep the important equipments running. I get a lot of small (a few seconds) to long (days) of outtages where I am. Not a lot of sun because of the trees but almost always windy. I haven't seen any videos on hooking up a wind turbine and nobody is clear if it's possible to use on this unit. I wrote to Bluetti Global and Bluetti Canada (where I'm from) and they don't have the same opinion. Have you ever done any wind testing in a Bluetti device?

[@nerijuskovalkovas9863]

Cool stuff

[@benjones8977]

Excellent review! Learned some things I didn’t know before about this system. The real issue is that it’s not worth getting in my opinion just because it’s limited on its PV input. In other words you can’t really run as a back up more than 24 to 48 hours. I have multiple charge controllers and a separate inverter and batteries. This is the only way to run 24x7. 🖖

[@Jasonoid]

I think it depends on the load you are running. I have been running my two full size fridges off this unit for about a month now. So in terms of running as a backup power solution it seems to be working well. I have a large solar input and that definetly helps.

[@benjones8977]

@@Jasonoid Running a whole house is a different matter. You’re also running at night time with no solar input, which can drain the battery quickly. A lot of it depends on where you live also. I live in the Pacific Northwest and it takes 7.5 kW PV just to get my batteries charged up. I have 9.6 kW of batteries. I’m using a 3000/24 V inverter. And I can still only run eight months out of the year, with the remaining four months using a generator when there’s no sun. The sun is so low during those four months, and the daylight hours are minimal, that you need a generator.🖖

Great recommendation on pricing scale Jason.... I'll have to think about it for sure!

[@johntate5284]

If you continue to add BC300"s you get the following. With 2 BC300's; $0.93 per watt. With 3 BC300's; $0.84 per watt. With 4 BC300"s; $0.79 per watt

[@ziggy29]

The thing is, because of the modular aspect of it, there are economies of scale with more batteries. Even now, a single B300 by itself is around 65 cents per watt-hour. So if you buy several of them, the cost per watt is reasonable. I think anyone who doesn't see a need for more than 1-2 extra batteries and doesn't need to have the potential for 240V service would possibly be better served with the AC200Max, unless they need the 3000 watt inverter.

The 150v limit is per string, do not go over 150v or it will damage the power station. You can have two solar arrays, one per mppt input, and each one can go up to 150v. I would probably stay below 140v just to be safe since in cold weather solar panels produce higher voltage.

[@briant2259]

Thank you for the info. I just got the AC300 & B300 May 1 weekend sale for $3,499. I almost went with the AC200MAX you can add 2 battery's but with the AC300 you can add up to 4 - B300 battery's. So it cost more but future proofs it if I wanted 4 battery's or get another AC300 and have 220v for the house. Especially if I use it the way you are 24/7. And I think you can AC charge the B300 along with charging through the AC300 at the same time to get max charge? I still need to play with it more and hook up to solar but so far i like it. Thank you for the in-depth testing!

Glad you got it on sale! I think you will be very impressed by the power station. Yes, you can add additional charging input on the B300 battery itself, pretty cool.

Thank you for the very nice review. It answered many questions I had and caused a few more. I have the ac300 with 2-b300. I also purchased 2 Pv350s. I am so new at solar so I am like a sponge. When hooking up your panels do you need to cover them with something first? I have seen people do this and wonder. Thanks for everything.

[@Jasonoid]

You do not want to cover the PV350 panels with anything since they already come with the ETFE coating. They should work well for you as they came from Bluetti.

[@dkheaton]

@@Jasonoid What I meant was some people cover the panels with a blanket or something while they are doing the connections, then take them off. Is that necessary?

[@Jasonoid]

@@dkheaton Ahhh, I see what you mean. Thanks for clarifying. If the panels are producing a lot of power or in bright sunlight, it would be smart to stop the power by covering them up. I usually make my solar panel wiring changes early in morning or later at night to avoid hurting the MC4 connections.

Happy Holidays!! I plan to install the transfer switch. On the AC300, you have a 30 amp that’s connected to your home transfer switch. Can you show what kind of cable that is and where can you buy one? Thanks

Hi, from the UK. Great Vid. How would you say the best way to charge this from the car whilst driving is? Ive see your other video when you tested various DC/DC chargers on the AC200 and wondered if this would be exactly the same, or if you'd recommend a different DC/DC controller / charger?

Any converter will work. You'll get more charging speed with a higher voltage converter.

Those are really heavy battery packs. Bluetti should have altered or modified the design to make them more portable or moveable.

[@jcstkd2345]

I enjoy your videos. Very informative. Regarding your parasitic drain; have you noticed in this unit when it’s connected to solar, it draws a lot of the solar power to function? I noticed if I was under 100w via solar, I’d come back in a few hours and my percentage would actually be a few percentage points less. Are you able to do a test on how much per the solar charger uses?

[@Jasonoid]

Did you have the AC inverter or DC output enabled while charging? Remember the AC inverter uses a lot of power so you need quite a bit of solar to even off set that by itself.

[@jcstkd2345]

@@Jasonoid no, they weren’t. I even did a test with a 12v 300ah battery connected to the solar connector. The batteries never went into “charge” mode. I know the “all in one” systems like the EG4 state what their idle power draw is. With the AC300, I liked how you tested for the idle power with the DC and AC. I just wonder what it takes to power the “charging” part of the system.

Hello again Jason, very impressed by your video on the Bluetti ac300. Crazy question but the unit itself with all the AC outlets and the screen on it, that is just the unit correct? In that unit there is no batteries at all the battery is that big one that connects with those big thick cables that stick out of the side correct? If so that's my only complaint with this unit.

Basically what I'm saying, is that without that battery you have hooked up to it that unit is basically useless correct?

Thanks to this Video I have a new way to power the EB3A and AC200P....24volts DC from the AC300!!! Yeah, lol, but there is one thing I noticed. there seems to be a 5-watt loss in that. It pumps out 214w from the AC300 but only 209 watts go into the AC200p

[@Jasonoid]

That's pretty normal, the difference in wattage when charging. Remember volts X amps = wattage so if there's any voltage drop between the systems you'll lose a little power.

[@McRootbeer]

Any progress on the 640wh diy build you were working on? Do you think a diy version of an ecoflow river mini (250-350wh sub 10lbs, small size) would save enough on cost/ have more features/capacity to be worth the hassle vs just buying one? Would a small power station/solar generator be a good starter project for someone with no electrical experience?

[@Jasonoid]

I just finished wiring it up this week. It's an interesting thought process... If you want just DC ouput and USB ports, DIY is totally worth it. It's when you throw in an AC inverter it gets dicey... You get heat and lots of extra cost. I'll do a youtube short video update soon and full video will be in June.

[@GlassicGamer]

The main complaint I have about Bluetti is the customer service and support. If you call it goes to an option for Service or Support and both have a full voicemail box and you can't even leave a message.

[@Jasonoid]

I have heard they are hiring more people to man their support group. I agree they can improve!

[@SetitesTechAdventures]

Is PV Priority actually a UPS mode? Looking at the manual only Standard UPS passes AC from the grid to the outlet, bypassing the battery. The rest of the UPS modes seem to just affect charging. Does PV Priority charge the battery with solar while passing AC through from the grid?

[@Jasonoid]

Probably not from what I have seen while testing since the battery capacity will drop slightly. So PV priority mode will use the battery capacity and will probably use some of those 3500 lifecycles as it's being used instead of having it plugged into the wall and using it as a UPS. What's interesting is that the AC300 in PV priority mode will match the power input / output with solar charging, kinda like it would with UPS mode.

I purchased the Bibene after I saw your video a year ago. Very happy with that purchased. I ended up getting another. Right now I’m curious to know how you use a transfer switch to run your parts of your home and still have power from the grid. I live in Florida so I have a whole house transfer switch for my gas generator when the lights go out. I have a 6 switch small transfer switch similar to yours but was told I couldn’t use it unless I cut all the electricity to my panel. Can you give me suggestions?

[@Jasonoid]

A transfer switch if wired correctly can be used at the same time as grid power. It isolates the power from each source safely. It's hard to know why someone told you you cant use that 6 circuit transfer switch at the same time.

I have time; I’m just looking to finish my solar project before next year’s hurricane season. I have a whole house transfer switch that’s mounted outside and I run my 10,000 watt generator. We were without power for a week in 2016 and 2017. I had no problems with my refrigeration because the gas ran everything. With my new setup, I plan to use the gas as a backup to the solar. Again..thanks and I’ll continue watching your videos.

[@larrylp2192]

I wonder what the idle consumption would be in UPS mode? If solar and utility are feeding the box, can it prioritize solar to charge before utility, or use both at the same time? If so, how much solar per day would be required to overcome the loses of having it running all day in UPS mode?

[@Jasonoid]

If you purchase two of them you can run 240v and 30 amps, or 6000 watts total...at least thats what I remember off the top of my head. You have to purchase their specific power 'hub' that syncs up the inverters to run in split phase power.

Any suggestions on why I get wattage into the unit but no charge to the battery??

A 100 watts alone might not be enough to fight off the power usage of the inverter, DC output, wifi, screen light and such. I'd recommend trying another solar panel. I've always had at least 300 watts going into mine.

With such a combo of higher voltage and low amps, you won't see much resistance / voltage drop. You'd probably be good for near 100 feet with that gauge. I run about 45 feet of 12awg and I don't see much drop at all.

Nice video. Quick question - when you talk about parasitic drain you express it as a percentage of total storage. Am I right in thinking that it's really an amount of watts per hour? So 1% is pretty obviously around 30watt hours per hour. If I had two b300s, it'd still be pretty much 30 watt hours every hour? No indication it would go up to 60 watts? My ideal use would be with three or four b300s, making up most or all of my daily usage, so very useful to know if the level of drain keeps pace with add-on batteries...

[@Jasonoid]

It's hard to estimate actual watts since there's no exact measurement of power haha. The only option I can measure overtime is the battery percentage on the screen. So yeah, 1% would be somewhere around 30wh or so be that's just an estimate. With two batteries it would still be around 30wh.
