Step 3: Connecting Power Optimizers In Strings - SolarEdge StorEdge SE7600A-USS Installation Manual

NOTE
Images are for illustration purposes only. Refer to the label on the product to identify the plus and
minus input and output connectors.

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 SolarEdge Site Designer for string length verification.
NOTE
The total cable length of the string (including power optimizers' cables) should not exceed
1000ft./300m from DC+ to DC- of the inverter. Use at least 11 AWG/ 4 mm² DC cables.
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.
2. Connect the rest of the power optimizers in the string in the same manner.
3. If you intend to monitor the installation, using the SolarEdge monitoring portal, record the physical
location of each power optimizer, as described in Providing Installation Information on page 61.
WARNING!
Input and output connectors are not watertight until mated. Open connectors should be mated to
each other or plugged with appropriate watertight caps.
Les connecteurs d'entrée et sortie ne sont pas étanches jusqu'à ce qu'ils soient accouplés. Les
connecteurs doivent être accouplés ou fermés avec des terminaux étanches.
