Product Overview
The Smart PV Optimizer is a DC-DC converter installed on the rear of PV modules in a PV
system. It manages the maximum power point (MPP) of each PV module to improve the energy
yield of the PV system, and performs functions such as module-level shutdown and module-level
management.

Installing the Optimizer
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.
1. After determining the installation position of the optimizer, remove and attach the SN label.
or
2. Install the optimizer based on the selected installation mode.
