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.

2. Install the optimizer based on the selected installation mode.

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.
