● ID7: When the sunlight
is normal, perform the
optimizer search
function again.
● ID8: When the sunlight
is normal, perform the
optimizer search
function again.
● ID9: Calculate the PV
string voltage based on
the number of PV
modules in the PV string
and check whether the
PV string voltage
exceeds the upper
threshold of the inverter
input voltage.
