Connecting the Strings to the Inverter - StorEdge Connection Unit with Glands

Connecting the Strings to the Inverter - StorEdge
Connection Unit with Glands
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 .
Connecting the Strings to the Inverter - StorEdge
Connection Unit with Conduits
1. Verify that the AC circuit breaker is OFF.
2. Strip 8 mm(5⁄16') of the DC wire insulation.
3. Insert the DC conduit into the DC-side opening. Make sure the conduit is firmly attached to the
inverter enclosure and sealed properly.
