WARNING!
SafeDC complies with IEC60947-3 when installing the system with a worst case
SafeDC voltage (under fault conditions) < 120V.
The worst case voltage is defined as: Voc,max+ (String Length-1)*1V, where:
Voc,max = Maximum Voc (at lowest temperature) of the PV module in the
string (for a string with multiple module models, use the max value)
String Length = number of power optimizers in the string
