Need Advice, charging Bluetti AC180 mixing 120w panels from two different manufacturers

[diysolarforum.8nkx7]

Hi, Very new to solar portable generators. I have a Bluetti AC180 that accepts Solar Input: 500W Max., VOC 12-60VDC, 10A. I also have 2 Elecaenta 120W Foldable Solar Panel - Nominal Capacity 120W, Maximum Power 18V, 6.6A (open-circuit voltage: 24~25V, short-circuit current: 7.2A) & 2 Bluetti PV120 Power: 120W Voltage at Max Power(Vmp): 19.6V Current at Max Power(Imp): 6.1A Open Circuit Voltage(OCV): 24.4V Short Circuit Current(Isc): 6.43A

My thinking is that I could connect all four panels, if I put the matched pair of panels in series, and then parallel connect those pairs to the AC180. This maybe a bad idea, which is why I am hoping someone with more knowledge/experience can share their expertise with me on this setup.

Thank you in advance for your time!

Place the two Elecaenta in series.
Place the wo Bluetti panels in series.
Parallel those two strings into the PV input.

You will be limited to about 360W due to the 10A input limit on the AC180. You'll be at about 36Vmp, limited to 10A

Thank you! I will give that a go.
