ATTENTION – A The connections can also be made with the wiring box detached from the
power module that can be connected later for commissioning. When working with the wiring
box detached, pay particular attention to:
- presence of ground connection (10)/(28)
- the top of wiring box must always be protected in outdoor installations with proper IP65
protection covers (optional accessory content in “PVS-175 Installation Kit”, to be ordered
separately). Refer to the dedicated “Installations of IP65 protection covers for wiring
box openings” paragraph for further information about the installation procedure.
NOTE – D Notes on the system sizing - Decisions on how to structure a photovoltaic system
depend on a series of factors and considerations, such as the type of panels, the space
availability, the future location of the system, energy production goals over the long term, etc.
A configuration program that can help to correctly size the photovoltaic system is available
on the FIMER website (www.fimer.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. 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.
