After some research, I think my best bet (for the AC180) would be a 600 watt inverter relayed with the ignition ā¦ that would allow me to charge through the AC input when the car is running. AND the solar through the DC input recharging all the time.

Hey Guys,
after some research I found out that its possible to change the output of the charger one to probably 48V (from 12V input). I want to use it in my camper van (12V input). I already got 4pcs. solar modules with 12v systemvoltage each in series connection, so in my opinion I should get 48V output, right?
If I connect now a parallel connection cable to my MC4 input on my AC200Max I should be able to connect the the solar panels and the charger 1 at the same time?!
Or do you think IĀ“ll will overpower my ac200 max because of the max input von 15A?
Here Specs of the solar panels
It would be awesome if I could get some help of you guys.
Thanks!
Hi @Steffen
I have a look at your panels. The crucial values are Voc and Vmp. Voc is the voltage without a load and Vmp is the voltage with load.
I think you mean the value thats shown for āSystemspannungā (Systemvoltage), right? I think they mean that this Panel is suitable for a 12V System, but dont have anything to do with the specs of the panel.
If you connect the panels in series, you would have around 96V in the worst case and im sure this will kill the charger.
If you put them in parallel you would remain on 20,5V/24,08V and would increase the current, which would be fine. The Charger 1 can take a lot.
Input Voltage:
12V-14V / 22,5V-28V
Input Amperage:
50A-12V / 25A-24V
Looking at the specs we have a problem. The charger take between 12V and 14V or 22,5V to 28V. The charging voltage 20,5V is too high for 12V and to low for 24V.
As long you stay within the voltage limit, its fine. The only thing that can happen is that you cant use the full power. AC200Max will take max 15A. No matter if you have 15A or 30A available.
To end this answer. The Charger 1 is designed for a stable 12V or 24V Powersource like the starter battery. You could connect the panels with a mppt to a battery and connect the charger 1 on the battery, to have a stable output.

Hey Erik,
first off all thanks for your fast and detailed reply.
Do u know if there is a dc relay to buy which in best can be controlled by home assistant or an other app?
IĀ“ll think to switch the input from solar or while driving to the charger would be the best in my caseā¦
greetings Steffen
@Steffen
The AC200MAX doesnāt have two DC charging ports (no two MPPTs) and canāt charge both PV and charger1 at the same time.
If you want to do that, get another D050S:
Connect the solar panel to the D050S then to the DC7909 port, then connect the PV charging port to the charger1. (When the solar panel connected to D050S, the voltage cannot be exceeded.)

Now, when i see the answer from Bluetti, i think i missunderstand your text. If you want to connect the charger 1 to your alternator und use the solarpanels at the same time, the solution with the āACā charging port on the AC200Max and the D050S is brilliant and simple.
Perfect, thank u guys! Thats the way IĀ“ll gonna do it! 
EDIT:
But I think it will be better to connect the Charger 1 to the D050S because it fits perfect with the output of 56V and 10A to the input of the D050S (12V-60V DC with max 10A). Right?
My Solarpanels would exceed the input of the D050Sā¦
Sorry, Charger 1 cannot connected to D050S. 
In the manual i could see, that the max input of the D050S is 60V.
My 4 pcs. solarpanels would reach 82-96V. So I think I cant use the D050S because they would they kill the D050S?!
Excited to see the launch of the BLUETTI Charger 1! Its high compatibility and efficient charging will definitely enhance the car charging experience.
Sorry if Iām missing something obvious, but is there any particular reason this canāt be done? Surely you can just run an MC4 from the Charger 1 to a XT90 input on the D050S like Steffen was saying? 10A at 48V would put you just below the max 500 watts of charging, within the listed limits of both components.

You can do that. But we donāt recommend because is redundant.
Hi I also have these three products but 900w of solar. So was hoping the charger 1 would work in the D050s then to AC200max any help please.
Iāve been looking for a dc-dc charger for my travel trailer to charge my 200ah lifepo4 battery while driving. Any reason I canāt just connect a Charger 1 to the Solar input of my existing MPPT 75/15) while driving? The charger 1 would give me more flexibility when not using the trailer.
I currently only have portable solar, but could they both be connected at the same time?
Is the Bluetti Charger 1 Isolated or non-isolated?
Thank you!
DC to DC chargers are typically desinged as isolated or non-isolated. Isolated is prefered for those of us running communication systems (like GMRS and HAM transmitters). Most overlanding rigs have some sort of communication transmitter in them.
Isolated helps reduce the chance of electronic noise and interference with the radios.
For instance: victron offers both isolated and non-isolated options.
Iāve searched quite a few places and canāt seem to find whether the charger 1 or the DC40s are isolated or not.
Thanks!
Dan
@dmulk Hi Dan, thanks for adding. After checking with the tech team, the Charger 1 is not isolated. May I ask in what application scenario you need to isolate it?
