Work on the Sunny Boy with the lid removed must be carried out
by a qualified electrician. Hazardous and even lethal voltages can
be encountered within the enclosure. Before working on the Sunny
Boy with the lid removed, the AC and DC voltages MUST be
disconnected from the Sunny Boy and it must be sure that all
capacitors are discharged.
The Sunny Boy must be disconnected from the mains and
precautions must be taken to prevent the grid being reconnected.
In addition, the connections to the PV generator must be
disconnected.
After isolating the AC and DC voltage you must wait approx. 30
minutes for the capacitors in the Sunny Boy to discharge. Only then
is it safe to open the unit by removing the lid. You must also make
sure that no voltage is present in the device.
The electronics inside your Sunny Boy 1700 is vulnerable in terms
of electrostatic discharge. Be sure to be connected to ground (e.g.
the enclosure of the Sunny Boy) before handling anything within
the enclosure of the Sunny Boy.

Sunny Boy Hotline before you start with
the installation.
