4.3 PV connection
Verify that the DC switch is in shutdown state before PV array connection
.
Note that the polarity of the array must match the polarity of the connector,
otherwise it will damage the inverter.
Note that the maximum open circuit voltage of the array must be less than the
maximum input voltage of the inverter.
PV array’s plus & minus poles are forbidden to ground (PE), otherwise it will
cause damage to the inverter.
Be sure to use the MC4 adapter.
The specific steps of the PV connection are shown in figure 4.3-1 below
