I have a ac200L and a charger1 and 1200w solar 140v voc how can i connect them all together without damaging my alternator or ac200L?
The AC200L has one DC input port. You can not connect 2 sources of DC, particularly at different voltages at the same time.
The C1 has a max V of 56V, Your panels are at140Voc. It would be a case of “Danger Will Robinson” 
Your alternator only drives the C1, the solar panels are independent of this. However, the risk is back feeding 140V into the C1. I assume it is diode protected but leave @BLUETTI to confirm.
@Mandp is correct, the solar panel and Charger1 as a DC input source cannot be connected to the AC200L at the same time.
They have different voltages, and when DC input sources of different voltages are connected in parallel, the higher voltage input source can easily damage the lower voltage input source.
