b. Connection for installations with solar
fields of different power ratings
(panels with different direction and/or
strings of different lengths):
If the installation does not have the solar panels on the
same plane, i.e., they receive different levels of irradiance,
either due to the shape of the roof or due to the different
inclination levels, or the lengths of the strings are not the
same, the connection must be made as follows:

A different solar field is understood to be those that are
made up of panels from different manufacturers, lengths
and/or different powers.
4. Insert the positive and negative connectors into the respective
DC input terminals of the inverter. If the terminals are properly
connected, they will make a clicking sound, as shown in Fig.

- Disconnect the AC circuit breaker from the grid side before
connecting the DC input terminals.
- The DC circuit breaker must be "OFF".
- Insulate the unused DC terminals with covers.
