We are new to the Bluetti system. My issue is that the system is saying it’s getting too much voltage from the solar array and shuts down. How do we wire these properly as right now the 4 panels are in series, so would it be best to remove 1 panel or connect 2 panels in parallel? Hope the pic was attached properly for viewing. Any and all advice is appreciated.
You need to research the difference between series and parallel connection. However, in simple terms and as an example using your data for 2 panels.
Parallel connection, you add the current of each panel 9.45 x 2 = 18.9A and use the voltage of the lowest rated panel or if the same the Voc of 45.6V.
Series connection, you add the voltage of each panel 45.6 x 2 = 91.2V and use the amperage of the lowest rated panel or if the same the Isc 9.45A.
So for 4 panels in series you had 182.4V with amps of 9.45A.
You also don’t say what Bluetti unit you are charging. 
But, most are capped at 10A and have a stated max Voc input, which if exceeded will damage or destroy the circuitry.

Hi @Medic welcome it would be helpful if you could tell us what unit you are using. As that will tell us what the max voc is that it can handle safely.
Sorry it’s the AC200max.
If you connect panels one and two in series as one set and then connect panels 3 and 4 as a set you will end of with two pairs of panels each outputting a max voltage of 90.2 volts. Now take these two pairs of panels and connect both pairs together in parallel with a “Y” cable and you will have a set of four panels outputting a maximum of 90.2 volts which is within the allowable range for your 200 max.

Thank you very much for the information. This won’t affect the amps and the unit?
You will have a maximum potential of 9.45 amps for each pair of panels connected in series. 18.9 amps max potential for the two pairs of panels. (In reality it will be less) You can go over the limit on amps since the Bluetti will only pull up to it’s maximum spec with no problems. You will also get the added benefit of higher output when sun conditions are not ideal .
When connecting in series, the volts are added together but the amps remain the same as a single panel.
When connecting in parallel the amps get added together but the volts remain the same.
Higher voltage transmits easier of distance and requires thinner wires to perform the work.
