Step 2: Connecting A Pv Panel To A Power Optimizer; Step 3: Connecting Power Optimizers In Strings - SolarEdge RESU10H Prime Series Installation Manual

26 Step 2: Connecting a PV panel to a Power Optimizer
5. Verify that each Power Optimizer is securely attached to the panel support structure.
6. Record Power Optimizer serial numbers and locations, as described in Reporting and
Monitoring Installation Data on page 57.

Step 2: Connecting a PV panel to a Power Optimizer

NOTE
Improper wiring may cause electrical faults in a PV system. To avoid electrical
faults, verify proper locking of connectors and avoid cable tension and
friction. Proper planning, materials and installation reduce the risk of electric
arcs, short-circuits and ground faults in the PV system.
NOTE
Images are for illustration purposes only. Refer to the label on the product to
identify the plus and minus input and output connectors.
For each of the Power Optimizers:
Connect the Plus (+) output connector of the panel to the Plus (+) input connector
of the Power Optimizer.
Connect the Minus (-) output connector of the panel to the Minus (-) input
connector of the Power Optimizer.

Step 3: Connecting Power Optimizers in Strings

You can construct parallel strings of unequal length, that is, the number
of power optimizers in each string does not have to be the same. The
minimum and maximum string lengths are specified in the power
optimizer datasheets. Refer to the
1. Connect the Minus (-) output connector of the string's first power optimizer to the
Plus (+) output connector of the string's second power optimizer. When connecting
S-Series Power Optimizers, be sure to connect the short Minus (-) output connector
