Possibly mixed strings moving a residential inverter

I extended two circuits from the roof panels to a new location for the inverter.the inverter and switch went from the right side to left of utility meter..
I'm not sure I grabbed the circuit correctly maybe mixed the two.
So my question is how can I tell without continuity test, could I amp probe and look for a balanced circuit.
Q/2 would the system still work if I did mix the circuit because I went on and held solid green and blue led...
I obviously don't touch much solar

DC voltage test

I'm don't understand. I had DC 180v +- on both legs of the two circuits. Seemed to be the same on both pairs. I guess I didn't know if I should go further and get DC clamp meter I only have a fluke T5600 with ac amperage.

Do you think it's ok because the voltage is equal and system is on. I appreciate your input thanks

Are these Voc (disconnected) voltages? Is 180V reasonably close to the module Voc multiplied by the number of modules in a string? If yes to both you are likely OK.
 
I checked the voltage with the system on or it was in standby if that is possible. Checked after I threw the switch and inverter was flashing green/blue Solar Edge
20a operating current
400v Voltage
480v. Max voltage
30a short circuit

With SolarEdge inverters the strings can be different lengths.

With the inverter off the string voltage should be 1V per module.

I'm back today I have 24 modules and with the inverter off 12v on both circuits. So I'm good correct?
I appreciate all of your help
