Warning

1. Only a few PV modules

are connected in series

in the PV string.

Therefore, the end

voltage is lower than

that of other PV

strings.

2. The PV string is

shaded.

Cause ID 1–18: PV strings

1–18

1. Check whether the number

of PV modules connected in

series in the PV string is less

than that in other PV

strings connected in parallel

with this PV string. If yes,

wait until the PV string

current drops below 0.5 A,

set all DC switches to OFF,

and adjust the number of

PV modules in the PV

string.

2. Check whether the open-

circuit voltage of the PV

string is normal.

3. Check whether the PV

string is shaded.
