Hello,
Recently purchased 2x EP600 with 6 BP500, cant find any information how to reach 12000w output.
How should it be wired correctly to output 4kW per phase?
Thanks

Hi Yaroslav,
The 4kW per phase output you mentioned has already been realized, but the circumstances of grid-tied and off-grid use are different.
Are you using the EP600 on-grid or off-grid?
If it’s convenient, could you let me know your order number so our team can contact you for a faster response?
Hi @BLUETTI ,
Now that is an interesting question “grid-tied or off-grid”?
According to my latest information, “off-grid” only works with 2x B500 and not with several. The questioner uses 6x B500, so only “grid-tied” would be possible, right?
Or is there news or an update that “off-grid” is now also possible with 6x B500 (or even 8x)?
Hi, I bought it locally in Ukraine.
Off-grid usage during power outages.
@SigiKa
EP600 can be connected to 4×B500s in both off-grid and on-grid.
But if you connect 2×EP600 + 4×B500s under off-grid conditions, you need to use one connection cable.
@Olvrick
Thanks for the explanation.
If it’s an off-grid scenario, you need a special connection cable to parallel two EP600s.
Could you please let me know your dealer’s name, or a photo of your invoice or receipt so that I can arrange for our European subsidiary colleagues to follow up with you?
So I cannot connect 2x EP600 and 6x B500 together in off-grid scenario? only 4x B500?
Local dealer in Ukraine is Stylus Store, importer Karma Digital LLC.
I can provide serial numbers if needed.
Can you please send me manual for parallel connection of 2x EP600 and part number of parts that im needed and where I can buy them in Europe\USA, through dealer these days it can take month or two to get needed parts since our situation in Ukraine.
Appreciated for any help
I know the connection cable, I already use it.
When we talked about buying a second EP600 with more than 4x B500 last year, we were told that “off-grid” works with exactly 2x EP600 + 2x B500 in one stack.
If I want to use more than 4x B500, only “on-grid” works in parallel (using a connection cable).
I had received the following diagram, with the note that I must NOT connect the two backup lines.
.
If there are any changes, please let me know.
@Olvrick In both on-gird and off-grid conditions, each EP600 is connected to a maximum of 4 B500s. You can have 2 EP600s, and each EP600 connects to 3 B500s.
The connection cable is currently in stock in Germany, you can directly contact our colleague Eric at Eric.bao@bluetti.de to make a purchase. Thank you for your kind cooperation!
Could you please share this info or source?
Thanks
PS: is it possible send private message to user?
Hello @Qwerty,
Unfortunately, I have no new information on this.
For the ‘off-grid’ variant, I had received the circuit diagram that I have already inserted above. As of September 2023 was 2x EP600 + 2x B500 in one stack.
Maybe @BLUETTI can post current information here, according to the answer above, 4x B500 per EP600 should now also be possible with ‘off-grid’?

@SigiKa One EP600 can connect 4 B500 units. The number of connected battery packs is not related to off-grid operation. 1 master to 4 batteries connectivity is a basic function, not a special application scenario.
OK, thx, thats the diagram I already using at home.
It is therefore still the case that the two backup lines must remain separate and a separate transfer switch is required for each EP600?
I would prefer it if I could use the max 12kW in one circuit and not two separate circuits.
Hello Yaroslav,
I came across your post here on the forum and was really glad to see that you’re from Ukraine and have already installed a Bluetti EP600.
I also bought a Bluetti EP600 during the blackouts — quite urgently, through Rozetka — but without the installation service. Since I’m not based in Kyiv, it’s been difficult to find qualified specialists, so the system is still not set up.
Now that blackouts seem likely to return, I’m trying to prepare in advance. My main issue is the wiring layout and the design of the distribution box (electrical panel).
If you happen to still have a wiring diagram or some photos of your setup, I’d be very grateful if you could share them.
Thank you sincerely for any help or advice — and for your time!
