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 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.
WARNING!
If using a dual-input power optimizer and some inputs are not used, seal the unused input
connectors with the supplied pair of seals.
3. If you intend to monitor the installation, using the monitoring platform, record the physical location
of each power optimizer, as described in Providing Installation Information on page 48.
