Cause
The voltage detected with SnapRS
devices disabled is higher than
expected.
PVRSS is enabled on the optimizer,
but the SnapRSInstalld device
setting indicates no SnapRS
devices are installed.
The number of SnapRS devices
listed in the SnapRSInstalld device
setting does not match the detected
number of SnapRS devices.
The panel output voltage is too low
to accurately count the SnapRS
devices.
7. Complete steps 1-6 for each PV link in the
system.
NOTE: To verify a PV Link is working properly,
navigate to the Mod.Settings page and con-
firm the SnapRSInstalld value matches the
number of SnapRS devices connected to that
PV Link.
