3.10.3 Notes on the system sizing
Decisions on how to structure a photovoltaic system depend on a series of factors and considerations,
such as type of panels, space availability, future location of the system, energy production goals over the
long term, etc.
NOTE – D A configuration program that can help to correctly size the photovoltaic system is
available on the ABB website (http://stringsizer.abb.com).
NOTE – D When configuring DC input and during the installation it’s needed to follow one basic
rule to avoid possible output power derating: All MPPTs shall be populated connecting at least
one string. For example, considering to connect 20 strings, proceed connecting one string per
MPPT and then connect the remaining strings in the selected MPPTs where you want to use 2
strings.
