2 Safety information
Check your plant configuration and the
string sizing with „Sunny Design“
(available at www.SMA.de) or with the
Sunny Boy Hotline before you start with
the installation. Exceeding the
specifications with the input voltage will
destroy the Sunny Boy. Overvoltage on
the DC side can even cause dangerous
explosions of the Sunny Boys input
capacitors and explosions of the
electrolytes coming from the exploded
capacitors.
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 700 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.
This appliance is not intended for use by young children or infirm
persons unless they have been adequately supervised by a
responsible person to ensure that they can use the appliance
safely.
Young children should be supervised to ensure that they do not
play with the appliance.
