5.4 Connecting to PV Module

Electric shock!

Pay attention! PV arrays will generate lethal high voltage when exposed to sunlight.

Ensure all cables are voltage-free before performing electrical operations.

• Make sure the PV array is well insulated to the ground before connecting an op-

timizer to a PV module.

• Please arrange the plant layout reasonably according to local laws and regula-

tions. If there are more than 30 optimizers per string, the rapid shutdown re-

quirement is not met. 3. Please check the input and output terminals of all

optimizers for reversed connection.

step 1 Connect the PV+ and PV- of the optimizer to the positive and negative terminals in the junc-

tion box of the PV module respectively.

Do not connect the PV module to the OUT+ and OUT- of the optimizer. Otherwise,

the optimizer or PV module will be damaged, and the loss is not covered by the

warranty.
