4.3 Installing Optimizer
The optimizer supports both clip installation and bolt installation. Please choose the appro-
priate installation method according to the site conditions.
4.3.1 Preparation Before Installation
Arrange the installation position of an optimizer reasonably to ensure that optimi-
zer cables can be normally connected to the PV module and an adjacent optimi-
zer. The communication distance between the optimizer and the inverter cannot
exceed 300 m at most.
Select the appropriate installation position of the optimizer, remove the QR code label on the
optimizer, and paste it onto the layout template as instructed.
