AC300 Strings voltage

Is it possible and safe to use this configuration with the two strings?
1st string - 3 panels with Open Circuit Tension: 50.15V and 465W (2 oriented to West and 1 to East)
2nd string - 3 panels with Open Circuit Tension: 45.50V and 600W (3 oriented to West)

Totaling 3195W:
1st string (1395W and the teoretical max voltage of 150,45V, as they are in different arrangement)
2nd string (1800W and the voltage of 136.5V)

The PV parallel shoud be on or off ?

Hi @bluetti_joaopedrosousaoutlookpt

i wouldnt recommend use the first string as it is. One string can handle up to 150V, which the first string is over. Also, this Open curcuit voltage is mostly meassured with 25 C degrees. If its colder and the sun still is shining well, the Voltage might be even higher. Its recommended to have about 10% buffer.

The second string is perfect. PV parallel should be off.

Thank you very much.
