The Bluetti AC500 and B300S has PROBLEMS! Constant Power Output From B300S.... Not Cool!

[@wvernhajek5426]

Received my AC500 and B300S. However the AC500 ac switch is not turning unit on. Unable to get response from Bluetti. Customer service stinks.

[@diyrenewableenergyelectron4996]

Do the push button power buttons turn the unit on? You should be able to press either the battery button or the main unit button and have it power up.

[@DuncanCunningham]

I have a AC500 with 2x B300S batteries. I got the 2nd battery about a few weeks after the first battery and the AC500. Before the 2nd battery arrived, I had the units connected to two solar panels to charge it up during the day and run lights at night. After 1 week I noticed that the lights were not on and the battery was not discharged had about 70%. I've not heard arking on mine but I had errors that I can not clear. It thinks there is power going to it from the solar even though nothing is connected. I have called and can't get through, can't leave a voicemail, I emailed and I got a message asking for more info and I've heard nothing back since, I've messaged them twice for more info. Over 10 days and heard nothing. I feel like I've sunk a lot of money into Bluetti devices and I'm waiting for help from them too.

[@diyrenewableenergyelectron4996]

Sorry to hear that! We haven’t received any response yet either. Not impressed so far.

[@ryanyoder7573]

Yeah support is close to nonexistent

[@0055ford]

Keep on waiting ! It looks like ot is there games untill you give up. Mine BLUETTI eb70s is under warrantee and i do not think that I will get anywhere. You will not even get info on who could service that product eaven if I offered to pay for repairing it. SHAME o This Company. Time to get together and start legal class action against Bluetti company. They have our money and we have there faulty product.

[@0055ford]

That is correct !!! No service. Only service you will get is game from them until you give up. They have our money and we have there non working faulty product. Time to start class action against BLUETTI. !!!!

[@Gaitngirl]

I know others have already mentioned this, but have you tried the cable arrangement shown on the Indiegogo site? Bottom battery to top battery, then to the AC500? It might be worth a try.

[@priscillabelliveau8231]

I purchased the ac500 and came up with the same problem with the power cords, tuff to insert into the power ports, I noticed a difference in the power pins. The ac500 top three pins were not in alignment. I measured the pin positions an noted a 1/32 difference in the points of contact. This was with the original cables packaged with the B300k. Bluetti is currently out of stock on the proper power cords. Hopefully to be sent out after end of the year. You should check the positioning of the top three pins with a micrometer. Forcing the plug into the receptacle could eventually break the plug connection.

[@JK_cookie00]

Thanks for sharing and letting me know NOT to buy the AC500 and look for another power station.

[@diyrenewableenergyelectron4996]

I think it is a very capable unit. Probably more capability than most people need. It is a new product and has problems so if it caught your eye, hopefully bluetti figures out the issue and resolves it! I wouldn’t completely write it off for this, but would definitely wait to buy. Thanks for watching!

[@0055ford]

Do not buy Bluetti ! You have no costumer service eaven you do have two or so years warrantee. They will 0lay games wit you untill you give up. They have our money and we have there faulty product. I have issue with BLUETTI eb70s and no working 120V outlets. O am giving up on this company. There product are good untill gets message SHORT and than trow out your product, you will get nowhere reparing

[@jesuswealth]

I just got my ac500 and b300s battery. Having the same problem. I got a 2nd battery today and tested it and the unit turned on and off normal. I even tested the old cable from the first battery I got. It worked fine. Its definitely the battery giving constant power causing bms errors. Will be contacting bluetti today. The joys of troubleshooting. 🙉🙈

[@maddeusdoggeus1]

Any update?

[@diyrenewableenergyelectron4996]

Nothing on my end yet. I don’t think bluetti is known for fast responses, unfortunately.

[@0055ford]

Good luck ! There is no service only games untill you giveup ! Warrantee is just shit paper to while the behind.

[@garymax992]

Have fun finding customer service.

[@diyrenewableenergyelectron4996]

We will see how it plays out. I plan to document/post videos regardless of the outcome. Here’s hoping it’s a positive experience. Thanks for watching and commenting!

[@0055ford]

That is correct !!!!. You will get tired of there games. Warrantee is good for toilet paper tov whipe the behind.

[@driverexcel773]

Wait a minute so if you get a 3rd battery (b300s), where would you plug it into the AC500 ? There isn’t a 3rd port, is the wiring diagram wrong and you have them connected wrong … shouldn’t they be connected piggy backed to one another ?

[@diyrenewableenergyelectron4996]

The plug setup changes with the number of batteries you have. It’s very weird to me but I’m just following the owners manual. If you have 3 or more you piggyback them. Thanks for watching and commenting!

[@davidmiller2378]

Watching for Bluetti response. I have same units. Mine work perfectly. Good luck.

[@diyrenewableenergyelectron4996]

Thanks! Yea, it’s pretty crazy how one battery works perfectly fine and the other is definitely doing something weird. Thanks for watching and commenting!!

[@Azeminad]

The footprint added by those poorly placed cables seems like a giant oversight to me.

[@diyrenewableenergyelectron4996]

For general use where space isn’t an issue it doesn’t matter much, but I’ll bet they could have caused quite a buzz if they made 90 degree connectors that hugged the machine. You’re right, it could be a game changer for RV use and tight spaces. Good point! Thanks for watching!

[@LarryRichelli]

The fact that Bluetti will not make 90 degree connectors is driving me crazy. I have to use one of my B300 batteries on it's end to make it fit. It is working fine this way but 90 degree cables would be wonderful

[@maddeusdoggeus1]

Suggestion. If you want to Demonstrate or test this anymore I suggest plugging into the AC 500 1st and then into the batteries so that if they are arcing it’s arcing on the battery not your AC 500 unit.

[@diyrenewableenergyelectron4996]

Solid advice 😂

[@lindazimmerman1109]

I turned off my AC control on screen, then turned off AC500. Overcast, no solar charging battery, batteries are dead. I plugged the AC cord into wall outlet and attached cord to AC500.. Problem: I cannot get the AC500 to turn on, so I can turn on the AC. This has not been an easy product to understand. I am not a very "techy" person, so having issues with Bluetti.

[@fastway007]

Interesting, I’m looking at that same setup for myself and definitely will be watching for Bluetti’s response. From everything I’ve seen about the company, they seem to have a good reputation and follow through with their products....we’ll see

[@diyrenewableenergyelectron4996]

I agree. They have a very good reputation both in the quality of their products and their customer service. It could be that this one battery was a fluke, but being a new product it is expected that there could be issues but we will see how they handle it. Thanks for watching!

[@CliveSmithy]

Does the same thing happen if you plug the possibly faulty battery into the top port on it's own? Also did you try the suggestion (made by "what's up with Cori?") to daisy chain them - see the instructions for the AC300

[@diyrenewableenergyelectron4996]

I haven’t yet but will soon!

[@maddeusdoggeus1]

@@diyrenewableenergyelectron4996 any update?

[@sammyrodriguez3784]

Hey what's up, one question have you try to switch cables? If it does the same then is the BMS battery, if it doesn't then it's the cable, that's why is so tight, give it a try.

[@diyrenewableenergyelectron4996]

Yea, we tried switching cables, it is the same battery regardless of the cable. Thanks for watching!

[@dangeroustoman]

did you try switching the batteries around.

[@diyrenewableenergyelectron4996]

Yes and we also tried switching cables to see if it was cable related. It isn’t. It does the same thing if the “bad” battery is the only battery connected as well. The problem is consistent and only related to the one battery. Very odd to me. Thanks for watching and commenting!

[@offgridwanabe]

I thought the batteries daisy chained on those maybe that was the old one.

[@diyrenewableenergyelectron4996]

They do when you have more than 2 but for 2 you plug both directly into the AC500. The connections for adding batteries is confusing. It changes based on how many you have to plug in. I couldn’t figure out the logic behind why the connection setups change but I just follow the pictures 🤣

[@offgridwanabe]

@@diyrenewableenergyelectron4996 So that would be the first thing I tried to see if daisy chaining on the top main connector would work. A friend has the same setup and his worked daisy chained.

[@diyrenewableenergyelectron4996]

He has an AC500 with the B300S’s? I’m going to take a multimeter to the plugs and see if there are any differences in the two batteries. The arcing is what makes me the most concerned since power is always on and it seems like it could damage components inside the AC500.

[@mikeselectricstuff]

@@diyrenewableenergyelectron4996 The battery should definitely isolate the plug pins when off. Check with a meter. I don't think it matters which sockets are used as all the pins are connected in parallel. The AC500 has seperate charge/discharge circuitry for each port, but these look identical and most likely interchangeable

[@diyrenewableenergyelectron4996]

That’s what I thought too! I didn’t have my meter for this video (it was very impromptu if you couldn’t tell lol) but I will check and see what it is at the plug terminals. Thanks for watching and commenting!!

[@markjob6354]

*Faulty Cable ?*

[@diyrenewableenergyelectron4996]

Seems to be the battery just has issues. The cables didn’t make a difference in performance. Follow up video will be posted soon! Thanks for watching.

[@christosl4395]

did you try switch the cables ?

[@diyrenewableenergyelectron4996]

Sure did. And tried switching which battery went in the plugs( top, bottom ports). It is consistently the same battery having issues. It’s a bummer for sure. Thanks for watching!

[@LarryRichelli]

I have the same exact setup and I do not have this problem. I turn the main unit on and both B300 batteries turn on.

[@diyrenewableenergyelectron4996]

Thanks for the feedback! Looks to be a random issue. Some people have problems, some don’t. Luckily for you, it sounds like you don’t! Thanks for watching

[@0055ford]

You are lucky fellow 👍until some gets wrong and you will get massage 'SHORT' than you done. No repair service.

[@TheResetGirl]

If you look at the photos on their indigogo site, all I see is daisy chained batteries, I don't see a setup like you are doing them. Although, you would think either way should work

[@diyrenewableenergyelectron4996]

I would have expected the connections to be different than what the owners manual says, because it is weird lol. But that’s what they say to do so I will follow it until they tell me otherwise! I also think the AC300 is connected differently than the AC500. 🤷‍♂️ thanks for watching and commenting!!

[@michaeljuers574]

For all of you contemplating spending 4 or 5 thousand on a Bluetti…buyer be ware. I have an older EB 150 which is now four months out of warranty and won’t charge. Good luck getting service for an out of warranty Bluetti. Max Oak, the company that originally marketed Bluetti, told me if it’s out of warranty they have no interest in helping me. Google out of warranty Bluetti repair. Apparently that’s a secret. Contacted Bluetti several weeks ago and nothing. I now have a thousand dollar boat anchor.

[@diyrenewableenergyelectron4996]

Thanks for watching and commenting!

[@0055ford]

I have BLUETTI eb70s under warrantee and that is good for toalet paper. Not even supplying anyone who could fix it eaven if i want to pay for it out of my pocket !. I am totally disappointed with Bluetti.

[@Brian-ly9xm]

I did konda expect this from Bluetti, almost all their power stations have problems from the BMS to overheating.

[@diyrenewableenergyelectron4996]

I never dug deep into the company, but have heard the name for years. Their reputation seems pretty good so hopefully they follow up on this. Thanks for watching and commenting!

[@CliveSmithy]

I own multiples of most of their power stations - I am also a forum member on their facebook pages and have never heard of this Brian!

[@0055ford]

No service in the case of product fails under warrantee. No more BLUETTI for me !! Will look to other company.

[@woodwood9797]

You didn’t hear from them ?!?

[@letterglettera9318]

Second line of the error messages, the battery is drained. Try AC charging the second battery then try again.

[@diyrenewableenergyelectron4996]

Worth a shot. Thanks for the suggestion!

[@eddiepeele9810]

Have you heard from Bluetti?

[@diyrenewableenergyelectron4996]

They emailed and said try a different battery port and only use the bad battery to see if it still malfunctions. There’s a follow up video posted. Thanks for watching!

[@eddiepeele9810]

@@diyrenewableenergyelectron4996 Ok, thanks. I've been looking at that system as well as one from Ecoflow. Don't know which system i'm going with but customer service from Echoflow seems to be much better from what I've been seeing.

[@Turnback79]

The two 309 work, but the 500 does not

[@jesuswealth]

My connection to the bad battery is also very tight like in the video. Almost imposible to put the plug in. You are not going crazy. Just a bad battery.

[@diyrenewableenergyelectron4996]

Is your power output similar? Does the AC500 turn on as soon as you plug your battery in? Same symptoms as me? I am asking because no one else has had issues. Thanks for watching and commenting!

[@jesuswealth]

@@diyrenewableenergyelectron4996 I'm having the same issues as you. I'm getting the 52.4 constant power from the defective battery and it's hard to plug like. your issues are exactly like mines. I just made a video and emailed it to bluetti today as proof that I have a defective battery. The good battery plugs in and ac500 stays off as it should.

[@diyrenewableenergyelectron4996]

Thanks for sharing. Sounds like they has a bad run for these. It seems like most batteries are fine.

[@Tommyr]

I never buy these new when they first come out. There are ALWAYS issues. I let others go through the BS for a few months til they get ironed out. Bluetti isn't known for fast responses to problems. Hope you don't wait too long.

[@diyrenewableenergyelectron4996]

You are wise lol. Usually with this type of stuff it is fairly easy for a company to test and build a reliable product for release, but production issues always leave some uncertainty. I think the company will get this problem resolved, but I think it’ll take longer than consumers would like. Fast responses to problems builds trust. Thanks for watching!

[@Tommyr]

@@diyrenewableenergyelectron4996 Well they all want to beat the competition so they rush stuff out. BIG mistake.

[@MrUpscaleman]

50 bucks says it's just a bad battery.

[@diyrenewableenergyelectron4996]

I agree. The AC500 seems to work correctly, just the one B300S is malfunctioning. Thanks for watching!
