Ac200l D40 to Ac240 Solar input

@BLUETTI Is it possible to use the D40 charger connected to the AC200L to charge the AC240 battery using the AC240 DC/PV input or other inputs?.

So,
1: Connect D40 to the AC200L 48v DC port
2: from the D40 DC output, connect an anderson connection to the DC/PV input on the AC240

Notes:
a) I understand it will convert 48 to 12v.
b) I only have one solar array, connected to AC200L as it can handle up to 145vdc, unlike the AC240… Hence when Ac200L is at 100%, I want to charge the AC240 with excess energy
c): I understand I can also connect the AC charging cable from AC200L to AC240 (but seems more efficient to do DC to DC) also, I would do the AC charging cable option when in a pinch.
d: I do not know if there is a cable that can connect from the D40 anderson plug to the DC/PV input type plug

Let me know!

Yes, but the charging power is very low.
Charging power to AC240 is only about 100W. You can buy an XT60(M)-MC4 cable online.

thanks, just to follow up.
1: I’d want to connect to the DC/PV input of the AC240 which hold 21amps… so 12v at 20amps would be 240nominal give or take. this since the D40 is 30amps. Am I correct on this? or what am I missing
2: Not sure about the XT60 to MC4 cable. The D40 has an Anderson plug… so should I not get an Anderson to MC4 or an Anderson to Aviaton plug? Can you let me know… So its straight from D40 ANderson connector to the PV/DC input of the AC240
note#2: I understand I can use the Aviation to MC4 cable that comes with the AC4. so Anderson to MC4 could work. but rather have it direct Anderson to Ac240.

No, because it will limit current to about 8.2A below 30V, not above 30V.
To ensure safety and avoid overloading, many devices will limit the current to between 8A-8.5A. Exceeding this current may overload the vehicle’s circuits and may even trigger a blown circuit or blown fuse.BLUETTI actively limits the charging power in order to protect the vehicle. This means that even if you use a 20A D40 charge controller, you will only be able to enter a current of around 8.2A.

Yes. Sorry for the mistake yesterday, it does take an Anderson-MC4 connector.
