I never make any decisions until I watch the next Will Prowse review. Take that to the bank! ;)

Dang not waking the expansions on charge is an insane oversight. Surely software upgradable

For it's price, it should be something stable. If the touch sceen panel is unreliable, who knows what else won't work.

Did they ever fix the problem with charging the external batteries?

Very interesting. I'm new to this technology. I just bought the AC 200 Max and one extra battery. It's just for a small apartment so I don't need a big huge solar panel arrangement. I'm a prepper so it's just for emergencies in case things go wrong. 45 minutes after I ordered it we had one of the worst thunderstorms in history, a tornado and a power failure. We've been having lots of fires here in Canada lately. So I wanted to be prepared in case.

I actually prefer the cables, instead of having integrated connectors forcing the user to only use the expansion in the stacked configuration.

You have not ever let me down with your tests..they are timely and answ my questions before i have them..and usually i see you AFTER others promote the unit..THANKS FOR YOUR HONESTY..im looking into a titan

You have one of the best formats for reviewing products. Keep up the great work! (and thanks!)

Hey Will... You're dropping em like it's hot today! Thanks and great job. 👍

Great video and review. I was seriously considering buying this since my daughter takes my Jackery 500 more than I do and I needed to upgrade anyway. Now I'll hold off until further reviews comes in. Thanks for your honesty Will

Just a note what you stated about the wires and the high stack and the weight and the potential for accidents is all valid. but you can also spread the weight out if you had a weight sensitive area that you were keeping this system. you could spread the batteries out from the generator and that could be a big advantage for some application say in RVs. That's probably a very limited use for that though.

I love it already! Not the product. The way you're pushing limits on the testing. Great job Will!

I did see "The Professor" AKA "HOBOTECH" discussing the APP features for the AC200 MAX and noting it's possible to power down the units remotely but not being able to power them on. He too was concerned about the lack of this feature. He seemed to think this could easily corrected with a update.

So if the expansion packs came back on when charging began or when the main unit was fully charged AND if the display had not locked up, this would be good to go....Thank you for the review and testing you do sir !! It helps the rest of us out immensely.

Almost bought this one. Thanks for the review

Once again thank you for doing the review. I am currently in the market for a solar power system that can be used as backup power and campsite power. I will wait for your next review before making any decision.

Will. Your power station reviews are outstanding and unbiased. I wonder if you would consider doing a video comparing customer service quality between the major power station companies after purchase. Customer service responsiveness is a major factor in deciding which unit to purchase. Specifically: Which companies stand by their product when something goes wrong? How long does it take to get a response when a problem arises? Who has the best warranties? Is there phone support or just email support? How are the reseller and BBB ratings for the various companies, etc. Thanks for your consideration.

I suggested to their rep a while back that they use right angle adapters for those heavy expansion cables for space saving and less chance of them getting snagged and toppled over. We can only make suggestions. I know a few people have had screen response issues(200p) and restarting the unit resolved them. It reminds me of the Microsoft Blue Screen of Death. Reboot and carry on lol. One drawback to more complex software.

Hi Will. Yesterday I received the Bluetti sp200 solar panels. They far exceed my expectations. I am going to get the Bluetti Max it is the unit I have long been waiting for. It is the only unit that will fit what I need perfectly

I have no Idea what your talking about, but its so interesting and intriguing so I subscribe. Keep up the good content!

Thanks for pumping out these videos, I really really appreciate it!!!

Hey Will Prowse!!! Great review of this product. If you get your hands on the new Pecron S1500, it would be absolutely fantastic to hear what YOU have to say about it. We appreciate the information that you provide. Thank you so much for sharing. 😎

You are such a jewel..I purchased this unit to power a small camp in Maine..

I was about to purchase one, but I will definitely wait!

Nice review. I like how honest your reviews are. Other reviews may or may not test as rigorously as you do and they may or may not disclose weaknesses of the reviewed products. I too am skeptical of unreleased products, especially crowd funded ones. I personally hate the term "solar generator" because these units generate nothing. They do store energy and supply it in a usable form.

Will, I first find your channel about two years ago when considering doing a van build out for camping and surfing trips. Then life got in the way. I've just purchased a van and have begun to collect my hardware of all sorts the the build. From the first of your vids I watched I've always been amazed and impressed with your knowledge and presentation skills. Going forward you will be be main source of technical advice for all things electric! I hope your health is well take care and thanks for all your great work!

Would love to see one of your honest reviews on the EcoFlow Pro. I have been 100% against crowd-sourced, too. BUT .. getting in on the 40% off early bird, was just too much of an attraction for me to pass up on. I got the big unit with an extra battery. Cost per watt hour was 1/2 the cost of the Bluetti. I'm patiently standing by for you to get one of those EcoFlow units. Thanks again!

Glad you did this review, I was thinking about buying the Bluetti Unit, but now I will be waiting for your next review before making this purchase. Would like to know what it can run, and for how long. 🙂

Thanks for the review….. was just looking into purchasing one… think I’ll wait now…lol

Thank you Will for your expertise. This helped make my decision on this unit.

Great Review! And really honest! Super Work! Also you are probably one of the first owners and power users of this system.. But now the Delta Max is out a long time, where is your Review? We need it.Also a comparing Video! Please do it ♥

Thanks Will, this is the video I've been waiting for.. 55-year-old that just completed his first small solar project with your help. Now to the next level. starting with this Bluetti or the EcoFlow here in Vegas

Great review. I’m interested in the Bluetti 300AC with the B300 batteries coming out in September. My concern is the max solar input of 2400watts. I’ve been researching on the best way to set up solar panels for this using 405 or 440 watt panels. I hope you will review the product and discuss the solar setup to go with it.

HEY Will thanks for the honest opinions on these solar systems. I am looking to build a completely offgrid all electric cargo trailer which will have to run a residential fridge a mini split computers etc. I dont know if these plug and play systems are the right solution for this though. I have seen your videos about different voltage systems like 12v 24v vs 48v and am still a bit confused as to which one I should be looking at. Could you please do a new video with all the newest options available and show which one would possibly be a good one for my situation? I am sure others would love to see it too. Thanks

The eco flow delta pro looks amazing. You can create a "whole home" solution by combining 2 of them with expansion batteries to get 240V outputs for air conditioning etc.

Thanks for the update. Though I've been learning about these things I still have a way to go. In the meantime it is quite an investment, not a cheap date. I like the Bluetti, but still not sure - Good to see you are doing well.

You are extremely thorough. Always a good video. Thank you. Now, I was about to purchase a AC200P but I was already hesitant because of if the screen doesn't work properly, I can't use it. I need to hurry up and order a solar Emergency backup gen. for home. Which one would you recommend please? I'm just stuck.

😀 Nice advice. I’m looking forward to watching your review of the Eco Flow Delta Pro. Here in Wales 🏴󠁧󠁢󠁷󠁬󠁳󠁿 we use 240 volts on all equipment, just in case anyone visits. Oh, it’s not that 🔆🔆🔆 here, so bring a raincoat.

I was at the point of purchasing this, because the $400 discount ends today. I wanted to get your opinion first. After your timely review, I think I'll wait. Thank You!

Love your videos! I wish so badly that you personally would create your version of the ultimate Bluetti/Ecoflow competitor battery generator!!! For production!

Looks like a great unit...love the battery supplements...I may purchase one (B230) as a charger for my 200P. In the mean time, I'm quite happy and trusting of my AC200P (I have alternate power should it ever "break.")

Thanks for the review on this unit. Your right it should charge all of them at once, it should maintain itself I'll wait for eco delta. Thanks for your hard work.

I like the Wco Flow Delta Pro the inverter is 3600 Watts & the 1200 watts of Panels.

I bought the first ac200 and get low voltage failures daily. and forget about the wireless charging on top. it only works when it wants to.. But, I use it for my bedroom emergencies, aka bipap. And I recharge all rechargeable like ebike batts, external batts. And for my Mac mini and accessories. Works great.... Looking for a unit to handle 650 watts 24/7 for my hydroponics.

Great Video. I've narrowed down my search to this model or the eco flow. The problem I have with bluetti is customer service is limited to electronic correspondence only. No contact phone where Eco Flow has phone contact and immediately your speaking to a rep. That to me is vital and peace of mind when investing this much money. I'm sure getting repair work done on either make can have it's issues but again talking to a person on the phone wins hands down in my book. Here it is July 25/2022 and the deals are on so I'm hoping bluetti has corrected the issues mention in this video. I ask them about the updated firmware on the previous 200p and they informed there were none and the unit is still the same as when first produced. That doesn't say much for them not to correct issues and just make another model instead. Thanks for this great review video.

I wanted to run 2000 W continuous, so I bought a 3000 W inverter. That way it wouldn’t heat up on me but it ended up frying the 120 V side of the inverter. I purchased a new 250v 100amp solar controller and now I’m looking for a different inverter/charger. I’m having a ground issue I believe.

Ty for the videos, it's helping me alot.

Eagerly waiting on an update to this review!

Can’t wait for your eco flow review ! Your reviews are the best! Valuable information , much appreciated!

A lesson I was taught almost 30 years ago: the moment you buy a new computer (or gadget), a better, cheaper one gets released. That’s how I feel about Wills reviews. I have settled on: whatever is the best fit by the time I’m ready. If it’s going to last 5, 10, 15 years, it’s inevitable that a year in its outdated. I’m content with that. Good review Will :)

I have watched A TON of your videos. Incredible job BUT, I most certainly have to watch it at 1.5x speed 😆 which I’m convinced is your ACTUAL speaking speed and voice. Thank you for your content🤙🏽

As always….thanks will. Everything that I have bought has been based off of your reviews and input. After building our first system several months ago, we have slowly continued to expand the system. 200ah of SOK batteries, 500w of mono solar panels, EPEver 40a mppt, and a Giandel inverter. It was originally going to be used for emergencies, but why waste free power. So we have it setup to provide power to parts of our home.

I just got my Bluetti AC200P on Aug. 31st. It is not reading wattage correctly amoung other things. Max Oak has just been giving me the run around. They keep having me make videos of the issues. Sometimes it will not show that there is any wattage being dispersed and when it does show wattage when I use more wattage it says that I am using less. I was very excited about getting one of these and when I seen that it was messed up I just thought " no big deal, they will just have to replace it." WRONG!!! They are not being cool about this at all.

Will, since you have had your test unit for at least a month (beta/pre production) and the delivery date for these units that go on sale today will not be delivered for three weeks after purchase today, do you think Bluetti may already have made software improvements? How long ago did you inform Bluetti about your screen problem? Thanks

Bluetti's EB series of solar generators had a serious flaw that few reviewers caught. If a shadow passed in front of the panels and caused the voltage to drop, the bluetti's would not recover to the higher input. So if you had 300w coming in, shadow passed causing the voltage to drop to 200w. Shadow removed, voltage remained at 200w. You had to unplug the power input cable, plug it back in and the input would return to 300w. I would hope these units do not have that flaw. Bluetti told me 3 different times and with three different batteries that this problem was solved. It was never solved. I return all three units, one just prior to warranty running out and got a full refund $1,700+! Besides, they take too long to recharge using solar. Would take 2 full days to charge and could not be used when recharging. You have to draw less power than what your panels provide or you would eventually run out of power. And at less than 300w input,not much you can run. Would keep your fridge going forever. They were good for those who would be charging them primarily from the wall. Solar would be a secondary input source. I will not buy one of these. I no longer trust their QC or their word. I was going to buy from Big Battery, same issue. I am going the DIY route. Thanks Will.

Good review. Completely agree that it's lame that the expansion batteries don't fully integrate with the main bank, requiring separate charging.

Thanks, Will! This might be a perfect solution for an off-grid RV. My AC unit pushes 1500 BTU so the battery would be drained quickly, but with the proper solar array and occasional shore power for recharge, this is a sweet solution for the technically impaired person.

Really enjoy your videos.

Firstly, Thank you Will for taking your time to teach. On to my question ( followed by my reason for said question). In a nutshell. I would like to run a refrigerator and charge a laptop/phone. What system would be best for my needs? Reason I ask is.... some of this is information overload.

I am extremely happy that Bluetti still trust your honest reviews. Your the best!

Enjoyed the vid. Will you do a video on the AC200P connected to the B230 Battery? How you connect? How do you charge? Ty.

VERY HELPFUL! Thank you Will! 👏🏼👏🏼👏🏼💕

That was my main concern is once the LCD/screen goes out..there is no other way to use the device anymore for (Ac200,ac 200p, ac200max). If there was some sort of dedicated buttons for the outlets, it would be better in case the screen fails. Great video as always!

Not being able to automatically charge the expansion pack/s is a bummer. You would assume that it would do that. But that's why we have your brilliance looking out for us. Thanks. And then the display not responding for hours.... Bluetti has to do way better than this. We'll see how they address it in the next update.

Thanks for your review.

Thank you, i was searchin for this kind of video!

Will I aways look forward to your reviews💪🏼💪🏼💪🏼💪🏼💪🏼💪🏼💪🏼 Many thanks 🙏🏼

Hey Will! Exactly what I have been waiting for! Your reviews are simply amazing. Your attention to detail in your setup and testing is second to none. Amazing point about the expansion batteries not charging automatically. That’s a bummer. Thanks for letting Bluetti know. They are lucky to have your comments. I hope they use them to better their system. I can’t wait for eco flow to send you a unit for review. That’s another very promising unit and in my mind there is no better person to review it than you. Thanks again Will. Be well.

Great review! I recently purchased the ac200 max! Regarding the screen turning off issue….we’re you able to use the bluetti app to operate it??

This is why I purchase 3 of the Eco flow generators and I and I haven't had any issues that hes speaking of right now. I understand one gentleman's comment was every time you purchase something something new always comes out that's true but at some point you have to Do something. And I'm not ragging on his comment he made a good point but if you sit around and wait to purchase one of these units and continue to wait you'll never get 1.

First, wow, great overview. Second, did they fix this issue with it charging the packs after the main one is charged?

Did they solve the problems of the extra batteries not turning on? And what are the best solor panels for these? Would it be better to go with bluttie or titan?

Thank you for mentioning that the 30amp outlet is 120vac. I ignorantly assumed they managed to get a 240vac output on here.

Another excellent review. I am also waiting for the EchoFlow Delta Pro to be released and then compare these two head to head. Looking forward to that review. Thanks!

Can you do one on the new bluetti eb55. It has everything you’ve been wanting in a portable solar generator. It has lifepo4. And yields around 89% capacity. At least that’s what another video showed. I only trust your research though. Everyone else is most likely just getting sponsored

Let me get this straight. He has used it for a month. You know he pushed it beyond its capacity. He said it is working well. He has his own personal concerns that most people have no problems with. He’s loaded, he has no concerns

What I wonder most with this system (or any other more DIY off grid system) is how you implement it to replace/complement current/legacy electric installations in houses and apartments so that plugs and appliances all draw autonomously from the off grid system first and then to traditional grid if off grid fails/depletes.

Hey im loving the video! I am looking to buy one and Y split it off my roof solar system. I saw you had regular glass solar panels. Was this ok to do with just MC4 extension cables with nothing additional added? Can we maybe get a more in dept video of how you connected your solar panels to your unit?

The screen locking up sounds like to me a hardware fault! From a pc side of view, normally when a hardware fault happens a reconnection of said hardware tends to fix the problem, but you can't unplug that monitor & replug it back in(or without taking the whole thing nearly apart that is) so yes, a software update to reconnect anything that isn't responding is a likely thing that may need to be added(or just set a reconnect flag whenever the screen is needed to come on)

Excellent review!

Love the video...we need honest reviews TY

Thanks, this video was very educating

EXCELLENT as usual, ty!!! HOW LONG CAN THIS UNIT OR ACP200P CHARGE SMALL SPACE HEATER OR AC UNIT? CC

Will P. Advised to wait until they get out all the bugs.. And he was right!!!!

I'm sure the 'not switching on the expansion packs on charge available' issue was a face palm moment for the product designers! Looks like a good unit, looks nice too. I may have missed it, did you run a capacity test? I assume it delivers its rated energy capacity. I actually don't mind the expansion cables, allows for user choice as to how they store them i.e. stacked, side-by-side etc. Also, could potentially allow for connection to existing LFP packs.

Great review. Do you know if Bluetti fixed the screen locking issue?

What a great review ❤️

I have the AC200P powering most of my kitchen, charged via the wall outlet. An expansion battery would be a good addon device. Living in Maine with a lot of cloudy rainy weather the expansion battery would give me extra capacity. The AC200P is used like a UPS and I also have 3 120w solar panels for the unit.

I had a AC200M/B230 combo shipped so we could try it out. Both came well packed. First thing I noticed is the power brick charger has in and out vent fans on either side that are always on and loud. 2nd thing is when the AC200 fans kick on, they are pretty loud too. I'm very sensitive to fan noise, so this is a little disappointing. I don't know how loud other brands are, but I really like silent or near silent cooling fans. PC computer power supplies, and video cards for that matter, used to be terrible when it comes to noise, but now make it a selling point to be very quiet. Wish Bluetti was better in the regard.

Is youre website up to date? Love your vids. Would love to see a video on your most fav :batteries/pannels etc. Ore The best system you can get

Hello Will... thanks for all your videos they are great... can the ac200max be coupled together with a 2nd ac200max for 240 like the ac300?

Will, I have the prior model AC200P, & as you have both, could you explain how to retro fit the expansion packs? & more to the point, could I use that system to add batteries of my choice? I don't want to return it, & my main objection is the 700w solar limit, plus no dedicated RV hookup. I believe I could set up separate charging solar panels for the additional batteries, if I could add these...I'd appreciate your thoughts on this & any advice you can provide. Cheers from your biggest 70 yr old granny fan! So thankful for all you do for us.

I’m looking into BLUETTI , just checked out your video and curious about your current thoughts, have they fixed issues you felt with? Thank you for all your testing and strenuous detailed work on this product. Curious if I should buy now or wait or look into a different company. Thoughts PLEASE!!

I am quite interested in the AC300, due to be pre-ordered 9/15/2021, but am concerned about Bluetti's business model. It seems to me that they develop a product, take orders for a batch, and then move on to the next idea. Since you can't actually buy the products, but can only place orders for them to be delivered in a few months, it would appear that you had better buy any expansion packs or model-specific accessories at the moment you place your initial order, as they may never be available again. I'd much prefer that they develop a system and then continually produce it; and support it with inventory and fixes. I don't want to spend $9000 on a system and then have to hold my breath. I agree that they should have a plan for securing these units. They may want to remember the 17 million Ikea chests of drawers recalled for tip-over hazard and deaths of 8 toddlers; so it is a real thing.

got 2 of these units. first one works super. second one i noticed that when the power gets down to about 20% or less it suddenly dies. happened a couple of times now. running a 350 watt dehumidifier off it so not a big power drainer. error logs and alarm show nothing. overall happy with the products. thinking to just shut the second unit down when it approaches 20% because i do not like the sudden power loss to the dh. charging from mains only. unit does not seem to be over heated during operation, fan kicks in as needed. havent had any touchscreen issues yet.

Life Saver!! You Rock!! Thank you!

Great review. Do you know if Bleutti fixed the screen problem locking? I am considering this model and the AC300. I like not needing to buy the expansion battery with The AC200 Max but not that screen locking issue.

Hey dude the best way to link them all would be to use a luggage carrier, there are some good ones that you can fit all three. True they need to fix that charging system.

Will... Think about a Solar A/C set-up with 'Wonderhussy' at her Death Valley place. I think the cross-fertilized content would be great!
