Thanks Snips. What about the D100P? I think I am more interested in that one.

I have some Questions 
-
On Page 17 of the D100P manual it says to use solar branch connectors to connect two panels. Can branch connectors be used again at the D100P end to split the current between the two MPPT controllers? The option is called PV Parallel enable on the AC300/AC500.
-
Page 22 DC output range 20V to 60V. Is the voltage range configurable in software between 20V to 60V? For example can I set 40V constant locked output that won’t reset after power loss?
-
Is the power draw limited by the D100P or the microinverter? For example can a third party microinverter pull the full 800 watts without the D100P restricting supply?
-
What is the maximum power draw from the battery only? Can a B300 output 800 watts using the cable?
-
What is the Maximum solar power that can be stored in the battery using the cable and does it support power splitting? For example can I store solar power in the battery and power the microinverter with solar at the same time.
-
Is the cable the same as the B210 to P090D cable used for connecting the B210 to AC200L or at least similar enough to be interchangeable?
-
Is the DC output split equally. For example if the battery can output 800 watts would that be split 400 watts over each output to the micro inverter?
-
Is there anyway to keep the battery connected to another control unit like the AC300 or does it have to be stand alone? If not can that be implemented even if it meant disabling the charging from the D100P. (This would be useful for people with off grid systems on variable energy plans who want to charge up their B300’s from the grid when energy is cheap, and then provide power to the house when energy is expensive).
Hello @Sideeffect
1.) The D100P and the A80P have two MPPTs. One on each side. So the value you mentioned (Up to 60V) is per String.
2.) No, you can set the voltage for yourself. Something similar is the new released charger 1 which take 12V or 24V Batteries as an input and can output up to 60V depending on your settings
3.) The Power gets limited by the A80P which only take as much amps to reach the 800W. You could use a third party inverter but have some restrictions because you cant integrate it into the App.
4.) Battery draw supports the full 800W to the grid.
5.) The D100P can handle up to 500W per String. So 1000W would be the maximum. This system supports powerspliting. So you can supply your house and charge the battery at the same time.
6.) You can have a look at the cables on the website. Since i dont have a AC200L, i dont know the plug.
7.) You can configure a certain value that the A80P should output. For example 300W. When the Panels produce 800W, 300W will go to the A80P and 500W into the B210.
8.)Im not 100% sure. I know someone connected a B300 and a AC200Max to the B300 which should work according to the support. Am still wating for my cable to arrive to connect B300 and want to try to connect a AC300 to it too. Officially its not supported to connect the AC300 to it.
Hope you get the answers you looking for!

@Snips1 Thanks for you help

(This would be useful for people with off grid systems on variable energy plans who want to charge up their B300’s from the grid when energy is cheap, and then provide power to the house when energy is expensive).
I think it won’t work because I assume that the B300 and b300s are slave units, for example they deliver power only if they receives an order from a master = an ac300 or… a D100p. I think that if you connect a B300 or B300S to 2 masters at the same time, it will have a problem!
But @Selfmadestrom test will help to decide!
Postscript: I use a b230 in powerbank mode connected to an external grid tie inverter and I note that the ac-dc adapter input remains activated (dc7909 socket) : so I charge at night when the price is low and I inject during the day when the electricity price is high, as you want to do. I think you don’t need to go through your ac300 to charge your B300 or B300s… You just need to plug a T500 ac dc adapter via the dc7909 socket to charge your B300 or b300s (it’s not possible for a B300k) in the evening, and you can keep the d100p and the t500 adapter plugged in at the same time. You plug the t500 into your grid by just inserting a smartplug so you can program the triggering during the hours when the price is low… No need to connect to the ac300 so for that!
Ps2 Well, I guess Erik wants to connect to his AC300 to see if he can request several B300 on a single balcony system or his existing solar panels array to recharge his B300 !
Hi @Selfmadestrom, Thank you very much for the replies. That answered most of it 
Just going back to question 1 again. The AC300 has two MPPT controllers as well and it is able to split current between them when you enable a setting called PV Parallel Enable in the settings. How it works is you put two 30V 12A panels together in Parallel with branch connectors (4 to 2 Wires) at the panel end, use a single pair of cables to go to the house and then use another branch connector to split the cable between the dual MPPT input on the AC300 (2 to 4 wires). You can then transfer the full 30V 24A which is split 12A each between the dual MPPT’s. I was wondering if the D100P also had this setting?
@Snips1
Yes I also think it won’t work currently I was just wondering if anyone knew what Bluetti’s plans were for example see below from the product page.
"### Q3.Is the system now compatible with BLUETTI Power Stations?
Not yet, but we’re working on it."
Ecoflow is able to manage it and you can connect to most of their power stations using the PowerStream so I was hoping this would be coming to Bluetti.
I have a B300 and a B300K so I could maybe use the B300 with the D100P and charge it like you say with the dc7909. My reservation for using this as a long term charging solution is that I have been seeing a lot of burned inputs recently on the AC200MAX dc7909. I haven’t seen this happen on the expansion batteries but wonder if that is just because less people are charging them this way or if the charge port is perhaps safer in some way?
The ideal would be to be able to solar charge and charge the battery from a AC300/AC500 and just transfer power efficiently to the D100P as requested, and I hope Bluetti can find a solution for that.
Interesting the concept of a single “power bank capacity” shared/recharged by different “energy users/providers” at the same time (D100P, AC300, AC500 and maybe AC200xxx…) This requires moving from a centralized model around the invert to a decentralized model or initially centralized around the lifepo4 cells.
I understand your concern about the dc7909 connector on the ac200max, some of which have melted. I feel concerned because I have 2 ac200max with a b230 and a b300k (thanks Bluetti for the quizz!) and in winter I charge them every day on the grid, a good part of the night when the price of electricity is lowest!.
I can tell you that since 2022, I have had no problems… While I charge them for almost 8 hours every night!
However, after the testimony and the impressive photos, I check that the connectors are properly inserted, and you can use strong adhesive tape or large rubber bands to mount the dc7909 plug so that it is always fully inserted.
Heating only occurs in the event of poor electrical contact, for example a plug that is not inserted sufficiently.
I admit that I have also invested in a small infrared camera, to plug into the USB C port of my smartphone, to be able to inspect from time to time the hot spots of my ac200max (ie the dc7909 connector in charge), the mc4 connectors, the solar panels to see if there are any “hot spots”.

It’s not that radical that is what the PowerStream is doing. It connects to the expansion battery port on power stations and is able to transfer power in both directions and the main power station is still usable.
The B300 is able to transmit the power from its 200 watt MPPT and DC charging port to and from other batteries in the system so it seems to me this functionality is already there.
Bluetti wouldn’t even need to go that far I would be satisfied with power bank level output from a single expansion port on the battery as long as the battery could still interface with the AC300. Currently enabling power bank disables connected head units.
It interest me too (d100p+ ac200max).
Hi Erik,
Do you know where we can get the VDE certification for A80P?
Thanks
Mark
Hi @Sideeffect
Both MPPTs can only handle a certain Voltage and current. There isnt a feature like on AC300 yet.
Hey @Mark83
Didnt find anything on the website.
@BLUETTI Can you provide mark with such a document?
greetings
Erik
Hi Erik @Selfmadestrom
Thanks for your help 
Cannot find anything too!?
Did you have to supply any certificate for your balcony solar system in Germany?
@Mark83 I did it for my first registration (Growatt Inverter), but not for the Bluetti System because its running more or less in test mode.
Please hold for a moment, I will forward you the document as soon as it is available from the safety regulations department.
Hi Erik @Selfmadestrom
Good news I received A80P few days ago and couldn’t wait any longer to test it.
All started pretty well, got it connected to wifi, green light, perfect and then … 2 error messages 
- Have you ever had these error messages when you set your balcony system?
Then I looked into the settings menu and I noticed that the ´feed to grid’ button was set on OFF by default.
2. What is this setting doing? Shall I activate it?
Thanks in advance
Mark
