WARNING!
Warns of explosion risk from batteries
▹ If modules are used to load batteries, the battery is to be
installed in such a manner that the performance of the
system and its users are not endangered.
▹ The recommendations and regulations of the battery
manufacturer concerning installation, operation, venti-
lation, and maintenance must be adhered to.
▹ Batteries should be kept away from persons and ani-
mals and protected from sunlight, rain, snow, or falling
objects.
▹ When loading most batteries generate gaseous
hydro-gen which can also explode. To prevent this from
happening sufficient ventilation must be provided and
open flames and sparking must be avoided. For outdoor
installations the batteries should be kept in a ventilated
container provided especially for this purpose.
Maintenance
SolarWorld recommends inspecting the system in regu-
lar intervals: All PV modules should be inspected yearly for
safe electrical connections, corrosion and intact mechanical
connections. Loose connec-tions can damage the module or
the module series. During this inspection it should also be
ensured that the wiring is in good condition. Given a sufficient
tilt (over 15°) it is usually not necessary to clean the modules
(rainfall will have a self-cleaning effect). Modules that are
installed horizontally (0 – 15° tilt angle) must be cleaned more
often because a sufficient self-cleaning from rainfall, as with
stronger tilted modules, is not given.
In case of heavy soiling we recommend cleaning the modules
using lots of water (from a hose) without any cleaning agents
and using a gentle cleaning implement (a sponge). Dried dirt
must never be scraped or rubbed away, as this may cause mic-
ro-scratches. Any problems that may arise should be solved by
an authorized specialist. Please also observe the maintenance
information of all components used, such as support frames,
charging regulators, inverters, batteries etc.
Disclaimer of liability
SolarWorld accepts no liability for the use and functionality
of the modules in case of non compliance with this User
Information. Since compliance with this guide and the
conditions and methods of installation, operation, use and
maintenance of the modules are not checked or monitored
by SolarWorld AG, SolarWorld AG accepts no liability for
damage arising through improper use or incorrect installation,
operation, use or maintenance.
