Issue 03 (2022-08-30)
Check Method
● Perform inspection and weeding as
required.
● Clean the site promptly after
weeding.
Major: The inverter is faulty. As a result, the output power decreases or the
grid-tied power generation is stopped.
Minor: Some components are faulty without affecting the grid-tied power
generation.
Warning: The inverter works properly. The output power decreases or some
authorization functions fail due to external factors.
Severity Cause
Major The PV array is not
properly configured.
Excessive PV modules are
connected in series to the
PV string, and therefore the
PV string open-circuit
voltage exceeds the
maximum inverter
operating voltage.
● Cause ID 1: PV strings 1
and 2
● Cause ID 2: PV strings 3
and 4
● Cause ID 3: PV strings 5
and 6
● Cause ID 4: PV strings 7
and 8

Solution
Reduce the number of PV
modules connected in series to
the PV string until the PV string
open-circuit voltage is less than
or equal to the maximum
inverter operating voltage. After
the PV string configuration is
corrected, the alarm disappears.
