Application Diagram


Tail Module Installation


  1. Clean the ground of the characteristic the location the tail module needs to be installed.

  2. Tear off the adhesive of the 3M glue at the lower back of the once more buckle, and paste it on the cleaned position.

  3. Clip the tail module into the decrease again buckle (The image is for reference, which can be adjusted in accordance to the applicable situation).

  4. Connect the enter and output terminals of the tail modules in accordance to the sequence tested in the decide below.

Head Module Installation


  1.  Open the head module and put the output buses (PVn-) of the PV strings into the head module.

  2.  Close the head module and fasten the buckle on the right side.
