Rectification
• Check the status of the Bluetooth
connection for the devices in your
PV plant Please note that the
Bluetooth connection can also be
interrupted by a lack of DC input
voltage. The DC input voltage can
vary depending on the time of day,
weather or the condition of PV
modules (e.g. covered with snow or
leaves).
– If necessary, improve the quality
of the connection.
– If you wish to start the device
update straight away, perform a
manual update (see
"Performing a Manual Device
Update" (page 69) and
"Performing a manual device
update via SD card"
(page 71)).
• Replace the SD card or format the
SD card in FAT 32 format.
• Remove the write protection of the
SD card.
The Sunny WebBox supplied as a
replacement device logs into the Sunny
Portal with a new plant ID. Sunny Portal
creates a new plant for this plant ID, even
if you gave the plant the same name.
• Assign the plant ID of the old plant
to the replacement device (see
page 56).
• In the replacement device, enter the
e-mail address of a user who has
administrator rights in Sunny Portal
for the plant.
• In Sunny Portal, delete the new plant
the replacement device created.
