Step 2, Connecting Each PV Module
to a Power Optimizer
WARNING!
Before performing this step, turn OFF the inverter by turning off the ON/OFF switch at
the bottom of the inverter and the AC switch of the main circuit board. All inverters in
an installation site should be switched OFF in this manner. This step is required to
verify that the power optimizers will output a safe 1V voltage during installation.

OP250-LV, OP300-MV, OP400-MV, OP400-EV

These power optimizers connect to a single PV module via its two inputs (a plus
and a minus).
