V600-12 String Optimizer Platform
Installation Manual: 57070013-1 H
Acceptable Input Configurations Between Parallel Optimizers
The number of modules on each input between parallel optimizers can vary within an array so
long as they meet the criteria described in the
Acceptable Input Configurations
within the minimum and maximum limits determined by Ampt’s design guidelines. An example
is shown below.
Figure 7: The number of modules per input between parallel optimizers can vary so long as they follow the acceptable input
configuration criteria and Ampt’s design guidelines

CAUTION
Over-current protection devices and conductors shall be sized in accordance with
the National Electrical Code (ANSI/NFPA 70); Canadian Electrical Code, Part I;
or the applicable standards, codes, and regulations for your region.
The output current limit of the Ampt String Optimizer eliminates the need for the 1.25
multiplication factor for over-sun conditions when calculating ampacity. The 1.25 multiplier for
continuous use is still required.
