The installation of this PV inverter is not particularly difficult, but we recommend that you follow all the instructions below.
P
RELIMINARY CHECKS
This inverter requires a grounding connection. Check that the grounding rod complies with current legislation and that the
grounding terminal to which the inverter will be connected is in fact connected.
Make sure that grid voltage is within the parameters specified in "Table 2" in the Appendix.
Check that voltage of the PV generator(s) is less than the "Maximum no-load voltage" in all temperature and irradiation
conditions.
Check that none of the PV generator poles are ground connected.
Verify proper PV generator terminal polarity (inverted polarity can cause permanent damage to the inverter).
With three-phase inverters, pay close attention to the correct connection of the neutral. Any phase-
neutral reversal causes permanent damage to the inverter, even when the inverter is off.

HOOSING AN INSTALLATION SITE
Choose a suitable installation site for the inverter‟s IP degree of protection.
In any case, do not install the inverter exposed to direct sunlight to avoid overheating and consequent limitations of output power.
Do not install inside cabinets, boxes or areas that are too small, where heat dissipation of the inverter can significantly increase
site temperature.
Leave some space above and below the inverter, at least equal to the "Minimum ventilation space" to allow proper ventilation of
the heat sink and space at least equal to the "Minimum distance" between the inverters in order to facilitate any inverter
maintenance.
