Step 3: Connecting Power Optimizers in Strings
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.
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 40.
WARNING!
Input and output connectors are not watertight until mated. Open connectors should be mated to
each other or plugged with appropriate watertight caps.
