Properly plan the installation position of optimizers to ensure that the cables between the optimizer
and the PV module and between adjacent optimizers can be properly connected, and the maximum
communication distance between the optimizer and the solar inverter is within 350 m.
Note: Use a
marker to mark
information on the
physical layout
template if needed.
Installing the Optimizer

Solar inverter
1. Select optimizers based on the installation scenario.
• For PV modules with long power cables, select optimizers with short input power cables. The
PV modules can be installed vertically or horizontally.
• For PV modules with short power cables, select optimizers with long input power cables. The
PV modules can be installed only vertically.
2. After determining the installation position of the optimizer, remove the SN label from the
optimizer and attach it to the physical layout template. For details, see instructions on the
back of the physical layout template.
