String Optimizer V600-32 Platform
Installation Manual: 57070021-1 A
Figure 10: Single PV strings may, and parallel PV strings must, have input fuses to protect the PV modules.
When input fuses are needed, use the appropriate calculations for your jurisdiction to size fuses
to ensure that your module strings are protected according to the maximum series fuse rating
on the datasheet for the PV modules.
Two-in-Portrait Wiring
To maximize bi-facial gains or to mitigate shading between fixed-tilt racking or trackers, keep all
PV modules connected to a given optimizer input within the same row.

DC-coupled Storage
When used in DC-coupled storage applications, the optimizer does not function as a blocking
diode.
Fuses may be required on single string inputs
