6 Maintenance and care
To enable the Sunny Boy / Sunny Mini Central to be used outdoors in places that are
difficult to access, the inverters have been constructed for low maintenance. To
guarantee safe operation, it is usually adequate to check the device visually for
damage approximately every two months. It should also be checked as to whether the
green LED is illuminated.
The Sunny Boy SB 2800i is not designed for installation outdoors. It is only suitable
for indoor installation.
However, in the interests of maximum yield, the operator should check weekly if
possible, under various conditions of solar irradiation, if the inverter's displays indicate
plausible normal operation (see chapter 4.4 "Description of the operating modes"
(Page 20)). Naturally, this information can also be obtained by using one of the
communications options.
Cleaning the inverter is only necessary if the heat dissipation is limited by dirty handle
covers (fan gills), dirty fans, dirty heatsinks or a dirty space between the Sunny Boy /
Sunny Mini Central and the wall. The dirt should be carefully removed with an
appropriate soft brush or paintbrush. A detailed description of how to clean the fans
(e.g. of the Sunny Boy SB 3800 or the Sunny Mini Central SMC 6000A) can be found
in the installation manual of the respective device.
If the display or the status LEDs are so dirty that they can no longer be seen, then they
can be cleaned with a damp cloth. Solvents, abrasives or corrosive liquids must not be
used!
