18 Maintenance and Care
The Sunny Island has been constructed for low maintenance. Thus, the necessary work is limited to
only a few points.
18.1 Enclosure
Check that the Sunny Island enclosure is mechanically sound. If damage (e.g. cracks, holes, missing
covers) endangers the operating safety, the Sunny Island must be deactivated immediately.
Larger particles of dirt should be removed from the device with a soft brush or similar item. Dust can
be removed with a damp cloth. Never use solvents, abrasives or corrosive materials for cleaning!
18.2 Cleaning the Fans
The cleaning intervals depend on the ambient conditions. If the fans are covered with loose dust, you
can clean them with the aid of a vacuum cleaner (recommended) or a soft paint brush/hand brush.
Clean the fans only when at a standstill. If it is necessary to replace the fans, please contact your
installer.
18.3 Display
It is best to clean the control elements with a soft, damp cloth. Never use solvents, abrasives or
corrosive materials for cleaning!
Take care not to accidentally press the membrane buttons during cleaning. Only clean the membrane
keypad when the Sunny Island is deactivated.
18.4 Function
Check regularly whether fault indications are present. If a fault indication is displayed, for which you
cannot identify any apparent cause, the stand-alone grid must be inspected by an installer. To ensure
optimal operation, the operator should regularly check the Sunny Island's entries in the error list at
short intervals (monthly, or even weekly), especially during the first months after commissioning.
This can help to discover hidden faults in the installation or errors in the configuration.
18.5 Battery
Inspect and maintain the battery at regular intervals. In this regard, observe all of the battery
manufacturer's specifications.
18.6 Disposal
Dispose of the Sunny Island at the end of its service life in accordance with the disposal regulations
for electronic waste which apply at the installation site at that time. Alternatively, send the devices
back to SMA Solar Technology with shipping paid by sender, and labeled "ZUR ENTSORGUNG"
("for disposal") (section 23”Contact” (page208).
