9. Verify that all wires inside the Inverter are firmly tightened to the AC terminal block.
Check that the wires are fully inserted and cannot be pulled out easily.
10. Close the inverter cover and tighten the screws with a torque of 9 N*m / 10.3 N*m
(for plastic screws).
11. Close the cover of the DC Safety Unit and tighten the screws with a torque of 9 N*m
/ 10.3 N*m (for plastic screws).
Connecting the PV Array to the Inverter
Connect the PV
array
to the DC input pairs. Additional PV arrays can be added to the
system by
parallel connection using an external combiner box or branch cables.
Installation and
connection of the combiner box must be done before connecting to
the inverter or DC
Safety Unit.
NOTE
Functional electrical earthing of DC-side negative or positive poles is prohibited
because the inverter has no transformer. Grounding (earth ground) of module
frames and mounting equipment of the PV array modules is acceptable.
NOTE
SolarEdge fixed input voltage architecture enables the parallel arrays
to be of
different lengths. Therefore, they do not need to have the same number of
power optimizers, as long as the length of each string is within the permitt
ed
range.
