Charger 1 sharing DC input port

I am a 72 year old retiree about to convert a cargo van into an apartment on wheels. I am new to Bluetti products. I have been researching power stations and I am impressed with the AC200L power station. I understand the power station only has one DC input used both for solar charging and alternator charging. Is there any way to have both the Charger 1 and the solar charging cable use the DC input at the same time? If yes, does that create any problems for the charging system? Otherwise, is there some way to have the solar and alternator charging work without having to depend on one DC input? Thanks,

Bill

The Shocking Truth About Using Bluetti Charger 1 with Solar Panels

The above is a link to a video where the host claims he was able to share the Bluetti AC200Max DC input port with the charger 1 and the solar panels using two Y (2-1) MC-4 connectors. He connected the negative wires from the charger 1 and the solar panels to one MC-4 Y connector. He also connected the positive wires of the charger 1 and the solar panels to the second Y MC-4 connector. Finally, he connected the positive wire of the Bluetti AC200Max DC input port to the Y MC-4 connector with the positive wires from the charger 1 and the solar panels. He also connected the negative wire of the Bluetti AC200Max DC input port to the Y MC-4 connector with the negative wires from the charger 1 and the solar panels. The host claims he turned the Bluetti AC200Max on and was able to charge the Bluetti AC200Max from the alternator and the solar panels at the same time with no problem. As to the volage mismatch mentioned by @Slotown, the host claims he changed the voltage of the charger 1 to match the voltage of the solar panels. Please comment as to the feasibility of this setup?
