SMA Technologie AG Safety Instructions
3 Safety Instructions
Caution! Overvoltage!
Check the system design using the "Sunny Design" design tool
(www.SMA.de) or by calling the SMA Service Line. Overvoltage damages
the Sunny Boy and results in the exclusion of all warranty claims!
Warning! High voltages!
Work on the Sunny Boy with the cover removed must be carried out by a
qualified electrician. High voltages are present in the device. Before working on the Sunny Boy with the cover removed, the AC and DC voltages
must be disconnected from the Sunny Boy and the capacitors must be discharged.
The Sunny Boy must be disconnected from the mains grid and precautions
must be taken to prevent the grid being inadvertently 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 cover. You must also make sure that no
voltage is present in the device.
Caution! Electrostatic charge!
When working on the Sunny Boy and handling the components, remem-
ber to observe all ESD safety regulations. Electronic components are vulnerable in terms of electrostatic charge. Discharge any electrostatic
charge by touching the grounded enclosure before handling any electronic component.
Notice! Entry of water and dirt!
Once the handle of the Electronic Solar Switch has been pulled out, the
Sunny Boy provides protection degree IP21. The Sunny Boy is then no
longer protected against water and contamination with dirt!
Grounding the PV generator
Pay attention to local regulations for the grounding of the modules and the PVgenerator. SMA reccomends to electrically bond the module frames, the racks
and all metal surfaces and ground these in order to have optimal protection of the
system and personnel.

5. 2 PV Generator Requirements
The Sunny Boys have two input areas "String A" and "String B", each equipped with a
separate MPP-tracker. The input area "String A" can be used for the connection of up
to two strings (modules connected in series) with identical properties (modules with identical orientation, identical type, slant and number). The input area "String B" can be
used for a single string, while this string can be different from the strings connected to
"String A".
“Sunny Design“ helps you design the system and check string size taking the relevant
inverter into consideration. Further information on "Sunny Design" is available at
www.SMA.de.
The unit has six DC plug connectors (four for String A and two for String B) for connecting the PV generators. The connecting cables from the PV generators must also be fitted
with this type of plug connector. The SMA order codes for the various connectors are
as follows:
• Multi-contact 3 mm: "SWR-MC"

Rating for a Line Circuit Breaker in a Photovoltaic Electrical Power Unit
Operated in Grid-parallel Mode
Various factors should be taken into account when selecting line circuit breakers. These
include, for example:
• The type of cable used (conductor material and insulation)
• Ambient temperatures affect the cables (higher temperatures result in a reduced
maximum current load)
• Method of routing the cable (reduces the ampacity of the conductor)
• Bundling cables together (reduces the ampacity of the conductor)
• Loop impedance [Z] (in the event of a body contact this limits the current that can
flow and therefore determines the response behavior of the circuit breaker)
• Sufficient distance between the circuit breakers so as to avoid undue heating (heat
can trigger the circuit breakers early).
•Selectivity
• Protection class of the connected load (VDE 0100, part 410, protection against
electric shock)
The following standards should be followed in all cases:
• DIN VDE 0298-4 (Cable routing and current-carrying capacity)
• DIN VDE 0100; part 430 (Protective measures "Protection of cable and
cords against overcurrent")
• DIN VDE 0100; part 410 (Protective measures "Protection against electric
shock")
For examples for the rating of a line circuit breaker, please refer to section 11 "Rating
for a Line Circuit Breaker" (Page 51)
A 30 mA RCD or FI circuit breaker must not be installed.
The Sunny Boy is equipped with an integrated universal current sensitive leakage-current monitoring unit. The Sunny Boy can automatically differ between real fault currents
and "normal" capacitive leakage currents.
Installation Guide SBTLHCMS-IEN080411 Page17
Installation Requirements SMA Technologie AG
The Sunny Boy does not generate any extraordinary leakage currents in normal operation. In some operating states (e.g. during self-test of the protection units) discharge
currents can occur which would trip a standard 30 mA RCD or ground fault circuit interrupter.
In case an RCD or ground fault circuit interrupter is imperative, you must use a
circuit breaker with a sensitivity of 100 mA or more.
5.3. 1 Line Losses
AC cable system impedance should not exceed 1 ohm. This is necessary, amongst other
things, for the correct operation of impedance observation. In addition, we recommend
dimensioning the conductor cross-section so that line losses do not exceed 1 % at the
nominal power. Line losses depending on the cable length and cross-section are shown
in the graph below. Multi-wire cables with copper forward and return conductors are
used.

a) The Sunny Boy can temporarily feed power into the grid with a maximum output
voltage of 260 V. However, DIN VDE 0126-1-1 stipulates that the 10-minute
average must not exceed a voltage of 253 V. That means, if the grid voltage is
continuously 254 V (e.g.), the inverter disconnects itself from the grid. In this
case, contact the local grid operator for assistance.
DIN VDE 0126-1-1 only applies in Germany. See section 8.4. 3 "Country-specific Parameter Settings" (Page 43) for all other preset country values of your
inverter.
