Connecting The Strings To The Inverter - SolarEdge SE8000H-AU Installation Manual

5. Connect the AC wires according to the labels on the terminal block.
6. Tighten the screws of each terminal with a torque of 1.2-1.5 N*m / 0.88-1.1 lb*ft.
7. Check that the wires are fully inserted and cannot be pulled out easily.
8. Tighten the AC cable gland with a torque of 2.8-3.3 N*m / 2.0-2.4 lb*ft.
9. Verify that there are no unconnected wires to the inverter and that the unused terminal screws are
tightened.

Connecting the Strings to the Inverter

Connect the string to the DC input pairs. If required, connect additional strings in parallel using an
external combiner box/branch cables before connecting to the inverter.
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's fixed input voltage architecture enables the parallel strings 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 permitted range.
Connect the DC connectors of each string to the DC+ and DC- connectors .
