Installing the 9V Battery
A 9V battery is supplied with the inverter accessories. Install the 9V battery in the holder on the top board
of the StorEdge Connection Unit and connect it to the battery pad.

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 according to the labels on the
inverter.

For easy access to battery connectors, it is recommended to connect the cables to the battery and
to set all the battery DIP switches to their correct positions while the battery is still on the ground,
before
mounting the battery according to the manufacturer instructions). The following procedure is
