SolarEdge RESU10H Prime Series Installation Manual page 42

NOTE
Functional electrical earthing of DC-side negative or positive poles is prohibited
because the inverter has no transformer. Grounding (earth ground) of panel
frames and mounting equipment of the PV string panels is acceptable.
NOTE
SolarEdge 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.
To connect to DC strings:
1. Strip 5.16''/8 mm of the DC wires insulation.
2. Pass the DC wires through the PV conduit.
3. Connect the wires to the DC terminals as shown below. Observe the correct polarity
as labeled on the terminals.
