Better information and much more specific explanation than the JUNK of generality we find on the BLUETTI Support videos. Thank you!
Again, this is a fantastic video--I have watched it many times. I am trying to use two AC500s in 50 Amp Split Phase to power my 50 Amp RV. I simply just cannot find a Y connector that has two NEMA 14-50P Male plugs and one NEMA 14-50R Female receptacle (like the black Y cable shown in your video from 9:17 to 9:48). I called at least 10 custom cable companies and the only cable that even comes close to what I need is used to connect two generators (two 50 Amp dual pin connectors) to a NEMA 14-50R. Almost all the other Y cables that have two Male plugs and one 50 Amp Female receptacle have two 30 Amp TT-30P Male plugs and one NEMA 14-50R Female receptacle. In my case, I can't use any kind of cable that only provides 30 Amps, all connectors must support 50 Amps. Do you have any suggestions on how to get a cable like the one you show in your video?
Excellent video! I appreciate you taking the time to explain this!

I see you are using the 50A outlet on the AC500 units. Are you using the 50A Y adapter from Bluetti? I am installing the Generac Homelink 9855 Transfer Switch which has a PB50 inlet box? Can you please tell me what the connector is on the end of the Y adapter you are using to connect 50A from your AC500s? I can't tell from the Indigogo website. Thanks!
Hi Kerygma - Yes I am using the 50amp y-adapter. The cable on the other end is a "ss2-50r" connection and will work with your PB50 inlet.
@@MyBluetti Thank you, and I really appreciate all that you are doing to help us with this equipment! It can get pretty confusing. I can't wait to get up and running.
Great information,thank you.
Question:I have the AC300 setup.Will be going straight into a rectangle box to the interlock in my main panel.
I’ve read on the bluetti forum guys having problems blowing out equipment.
They claimed a bonding plug was needed plus a switched neutral.
One guy claimed he burnt out his furnace blower.
They compared it to having a floating neutral on a home generator as the neutral should only be bonded in on e spot(the main panel).
Do you have any advice on this?
Thank you
Best explanation 😮
Thank you
Great job on this video. I have found the Bluetti website very hard to navigate not to mention they do not elaborate on this subject. Thank you. I was about to decide I did not want a Bluetti system. I wanted to make sure that whatever I decide to get I would be able to have an 230volt ac or in this case a 240 ac output so that I can run my well pump !
Yes, Bluetti's site needs help, and their marketing team is terrible. But the products are pretty good. I do 240V from my two AC500's. Having community, such as this UA-cam channel or some of the Facebook groups, makes it a lot easier to find the info you need.
Thank you for such good information on your videos.
I bought a Bluetti AC300 and I wanted to use it for time of day for my utility company. I was wanting to plug my ac300 to an outlet on the bottom of my home panel. And I have a sub panel transfer switch that is a manual transferthat I used with my gold zero that is attached to my home panel. What is happening is that I will have the ac300 plugged into the outlet and then when I power the outlets on the ac300 while it is connected to the manual transfer switch the outlet pops at the outlet. How can I fix this?
Thanks David, Another great video.
Very welcome
Thanks so much for the great information! I just bought 2 AC 300’s and 2 B300’s. I’m in an RV and don’t need 240V but want to take the 2 30 amp outputs adapted to 1 50 amp to run the rv. Just ordered the adapter. Quick question, this will give me 50 amps? Thanks!
For the split phase setup, do you solar charge through each AC500 normally (3000W for each one). What about if you use solar panels on only one of them while in split phase. Does it balance out the charging of the batteries?
This AC500 & AC300 split phase video is exceptional! I have 2 questions: First, I have a 50 amp plug on my RV-can I use two AC500s in split phase with a 4-prong Y-connector connected to the NEMA 14-50R on each AC500 to power my RV when I connect my RVs 50 amp plug into the Y-connector’s NEMA 14-50R; Second, which specific solar panels (what wattage and how many panels) do you recommend per B300S battery for recharging a battery as quickly as allowed-I purchased a total of 4 batteries so far (2 for each AC500).
Thank you for the feedback. For solar panels I can't recommend a brand, as the panels I used aren't sold any more. However, I do have a solar calculator on my website that you can use to check panels configurations to your AC500 systems. You want to stay below the 150v Max voltage of each mppt controller though.

Thank you for your concise explanation!
Can you charge ev with that 14-40 plug? Do i need to plug in those little neutral bond adapter for the ev charger to work? If so, do i plug that adapter to the master or slave? Or both?
I want to know as well
I need 50AMP capacity. Will they run that and how long? Thanks
You mean 50amp at 240 volt? Each AC500 can only sustain 42 amps at 120V. Add them together, that makes 42 amps at 240V. So no, they can't do 50 amps. But, close enough for most purposes.
Am I right in assuming you're asking because you have an RV that operates on 240V 50amp? Most likely this will be fine for you. Two 15K BTU AC's draw about 1250W each, which is about 11 amps each at 120V. That leaves plenty of extra for your microwave, fridge, and whatever else you're likely to run in an RV.
As for how long it'd run things, you just need to add up the watts that you plan to use, then divide your total battery capacity by that. Two B300S batteries have about 6,000Wh of capacity, so if you run two 15K BTU ACs full time at 1250W each, that's 6000Wh/2500W = 2.4 hours. You can purchase more B300S batteries if you needed. If you just run one AC, then you get double the hours. Just gotta learn how to convert between the units, and it makes these calculations very easy.
@@masonmcglothlin5101 Back when my building channel was active I wanted to show the potential by running my Delta Table saw on site and using a MIG Welder (240v) to build my shop. It was a great opportunity but I have moved on but I have friends locally that have worked with Bluetti on their channels. I wish I would have heard back 6 months ago.
is the AC500 cable from Bluetti u mention available? Don't see it on their shop
I have been running a single AC300 with no problems. It feeds a Generac Transfer switch. The AC300 only powers the transfer panel, nothing goes to the grid. I use PV priority mode and a 110v outlet feeds the AC300 if the batteries get below 15%. I am going to bring in the second AC300 using the communication cable and Y-cable like you use. According to Bluetti I can still feed 110V from the grid to each AC300 for when the batteries drop below 15%, but each AC300 has to be fed from a different phase from the grid. I have run a circuit from each phase and each one feeding it's own outlet. Two 110v outlets, 1 from phase 1 and the other from phase 2, Obviously one will feed the master and the other will feed the slave. You have talked about problems when feeding from the grid. Is this still an issue? I do not have large draw items on the transfer box. I will also balance the loads to each leg. I have never gone over current and rarely have a draw over 2000W. Normally It draws between 300W and 900W. There are 2 refrigerators and 1 small freezer. I will probably limit the grid draw to 10 amp max. The grid will only be to maintain the least amount of power needed until the solar panels start charging the batteries back up. Unless we have several really cloudy days I never pull anything from the grid for the AC300. I really want to use the AC300's automatic use of the grid when necessary. I would rather not have to use the T-500's to directly charge the batteries. I do not have the automation like you do. And again, the single AC300 if working perfectly, pulls from the grid if necessary, neutrals are separated and all that. I would really like to hear your opinion and possible problems on feeding the Dual AC300 240V setup from the grid. Thank you so much for all of the videos you have made and all of the time that has gone into them.
Here is the most current video from Bluetti for connecting the dual AC300s

Hi Toxic. I responded to your other message on my other video
We're trying to link two AC500 in split phase mode as well. Our electrician is not seeing the voltages he expected; this video may be of help. I am not seeing the 50-Amp Split-Phase output cable on the link you provided. I do see the Split-Phase Charging cable, which we already have.
Hi John - make sure that your system in set to Split-Phase on both systems.
@@MyBluetti One is set to master, the other to slave. That's what you mean, correct?
I'm not sure we'll need it since the electrician is making his own cable. But do you have an updated link for the 50-amp split-phase output cable? I have not been able to find that on Bluetti's site.
Thank you for the video's, they are super helpful!
What extra equipment are you referring too?
Do the new Bluetti home integration kits resolve the split phase issues?
The kit itself wouldn't do anything to do that. The kits are just a manual transfer switch, or subpanel with an interlock kit. They just receive power from the Bluetti power stations (or a portable generator or some other competitor as long as it has correct cables). They do nothing to change how split phase power works.
Split phase with 1 AC300 and 1 AC500
Can they communicate with proper cable and output 240v with box or cable?
Negative. The AC300 and AC500 are not compatible to work together in Split-Phase. You must have either two AC300s or two AC500.
It requires extra equipment to make it pull power evenly. I wish It would have known that before wasting money on the split phase unit. It will run one battery pack down before the other. It will run the master down much quicker than the slave.
What extra equipment can make it pull power evenly?
@@JohnHaganVA you have to buy a charger and a plug. Then you have to plug the charger into the slave and then plug it into the battery pack on the master. So in essence. You charge the master battery using the slave inverter. Yes I know it's silly. And not one piece of literature let's you know. You find out after you have issues and have to have near endless discussions with tech.
@@boonelipsey5393 Just wondering out loud. Instead could you have 3 or 4 B300S on the master and 2 on the slave to help balance?
@@JohnHaganVA If you can afford it. That certainly would work. The problem I had. Was the master was pulling about 95 percent and the slave was pulling 5. I had 5 hrs of battery capacity. But only got 2.5 hours because the master shuts down when the battery gets to low.
@@boonelipsey5393 I'm not fully up to speed on this, obviously. Since each AC500 provides one leg of the 240v "hot", I assume each AC500 essentially provides power to half of the home circuit panel. Is the problem really that the "master" is always doing more of the work, or is is possible that in your implementation, your "master" happens to be linked to the majority of your home's load?
We are still working to implement split-phase power with the help of an electrician and learning along the way. We did notice that when left on in split-phase mode, with no AC output enabled, the master drained much more quickly for no apparent reason. We've only been through one battery cycle in that scenario so far. But, it does seem to reinforce your point. Charging the master from the slave to account for this must add a fair amount of incidental power loss. It would be great if a firmware update could address this issue.
Your Videos are very instructive.
I own 2 AC500s and 6 B300s batts, want to set them up similar to your system where I store rooftop solar panel power in the B300s' and do not necessarily sell back to the grid.
I noticed a second splitter cable feeding into a transfer box.. What is that used for in your system? External gas generator or?
Also, how did you solve the unbalanced battery bank charging issue referred to below by boonlipsey below. Sell back the AC500s and get AC900s???
All I know is that that's system and all its batteries and useless solar panels cost $24,000 something a little bit more and the solar panels that I will not be able to use cost so much. I would rather have regular solar panels and regular solar panels cost less money you know what they call the regions solar panels is what I want when's it has a frame on it a inch thick by 39 inches by 65 inches is what I would like to get. You know something I can use.
These system are not for everyone. It all depends on your use case. In my case I did not want a grid tied system and I wanted to store my excess power from my needs, not sell it back to the grid company. In total, my Bluetti system was much less than my neighbor's systems which cost $60k+... and they don't have stored backup, and their system goes offline when the grid goes down.
After the federal tax credit, for $15K I was able to get two AC500's, two B300S's, the home integration kit (manual transfer switch), 6.4kW of solar panels, and pay the electrician to wire up the transfer switch and solar installers to mount panels on roof. That's not too bad, all things considered. Very much in line with prices I saw from traditional solar installers with traditional batteries (Tesla Powerwall or Enphase). The great thing is that it's mostly portable and modular. I can add or remove additional batteries as I see fit, or use them while camping etc. I even started out with a single AC500+B300S, and was able to add a second setup for split phase without electricians help.
What's the max current on this 240v split? For example if the dryer is running and the HVAC kicks on will it trip? What if you add in the well pump, hot water heater, etc?
No one seems to be able to answer this question
At 2:20 he starts to pan down to the fusion box. Below the 240v receptacle it reads 200-240v/30a max.
That’s a max draw of 7200 watts.
Note that most electronics are only rated to run 80% of their listed rating on a constant draw. For this it would be 5760w max constant draw. Though it should handle surges up to the 7200w max.
