SMA Technologie AG Installation requirements
4.2 PV generator requirements
The Sunny Boy 700 is designed to be connected to up to two strings (PV modules
wired in series) having a homogenous structure (modules of the same type, identical
orientation, tilt and number).
The „Sunny Design“ tool will help to dimension and check the size of your string with
respect to the inverter you intend to use. Information about the „Sunny Design“ tool
is available at www.SMA.de.
The unit has four DC plug connectors (two for each string) for connecting the PV
generators. The connecting cables from the PV generators must also be fitted with this
type of plug connector. A pre-assembled set for connecting the free cable ends from
a string is available as an optional accessory. The SMA order codes for the various
connectors are as follows:
• Multi-contact 3 mm: "SWR-MC"
• Multi-contact 4 mm: "MC-SET"
• Tyco: "TYCO-SET"
Limit values for DC input

Rating for a line circuit breaker in a photovoltaic electrical
power unit operated in parallel with the low-voltage grid
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 behaviour of the circuit breaker)
• Adequate clearance between the circuit breakers in order to avoid excessive
heating (automatic circuit breakers trip earlier when they are warmer)
• Selectivity
• Protection class of the connected load (VDE 0100, part 410), Protection against
electric shock
Please have a look at chapter 9 "Rating for a line circuit breaker" (page 45).
1
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)
1. The standards mentioned above are to be only used as a guideline for your
installation. They apply for installations in Germany. Please note that other
standards will apply for different countries throughout the world.

SMA Technologie AG Installation requirements
The system impedance at the installation site of the Sunny Boy 700 must be less than
1 Ohms for the islanding detection and the fuses to work porperly. In addition, we
recommend dimensioning the cable 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. It shows a multi-conduit cable with all conduits made
of copper.

Connecting the AC output
Before you connect the mains cable to the AC connection socket,
make sure that no voltage is present at the cable.
A round plug connector system is used, which allows various cable diameters to be
used in the cable outlet. For this reason, the accessories kit includes a PG13.5
pressure screw and a PG16 pressure screw. Check which screw fitting is the right one
for your AC cable.
To connect up the AC output, follow these steps:
1. Check the grid voltage. If this is higher than
260 V, the Sunny Boy 700 will not be fully
operational. In this case, contact the local grid
operator for assistance.

PV string (DC) connection
To connect up the input, follow these steps:
1. Check that the PV generator connectors have
the right polarity and do not exceed the
maximum string voltage of 250 V (DC). See also
section 4.2 "PV generator requirements"
(page 15).
Caution! Dangerous high voltages may be present. Danger of
death!
2. Taking one DC plug connector at a time,
measure the direct current voltage between one
DC plug connector of a string and earth
potential.
3. If the measured voltages are constant and if
their total is roughly the same as the open circuit
voltage of the string then there is a earth fault in
this string. Its approximate location can be
deduced from the relationships between the
voltages.
PE
Do not connect strings to the Sunny Boy 700 that contain a earth
fault until you have fixed the earth fault in the PV generator.
4. Repeat points 2 and 3 for each string.
5. Connect up the faultless PV generator strings to
the inverter.
6. Close off the unneeded DC input sockets using

5.3 Setting the input voltage
The Sunny Boy 700 was developed for a nominal output power of 700 W. This
corresponds to a PV input voltage range of 119 ... 250 V DC at the nominal output
voltage.
For solar generators having an input voltage range of 96 ... 200 V DC or 73 ... 150
V DC it is possible to adjust the Sunny Boy 700's input voltage range accordingly. In
other words, it is also possible to connect smaller PV generators to the Sunny Boy
700.
Input voltage range Nominal output power
119 ... 250 V DC 700 W
96 ... 200 V DC 600 W
73 ... 150 V DC 460 W
For small PV systems please note:
The Sunny Boy 700 must be adjusted for the number of PV modules so that it
works in the optimum range.

The Sunny Boy 700 is factory set for the highest input voltage. To be able to use it
for smaller PV systems, you need to make some minor modifications to the unit. Inside
the Sunny Boy 700 at the top right there are a number of terminal blocks. The top
double terminal is not relevant for adjusting the input voltage range. Below the
double terminal there is a single terminal. This terminal is used to adjust the input
voltage. Below this terminal there are two free slots. You can see the input voltage
ranges associated with the slots from the drawing below.

The slots for the jumpers are
mounted on the Sunny Boy 700's
controller board. When supplied
from the factory, no jumper is fitted.
A jumper only needs to be used if
you want to operate the Sunny Boy
700 with a lower input voltage, i.e.
at 96 ... 200 V DC or at
73 ... 150 V DC.

To adjust the input voltage, follow these steps:
1. Open the Sunny Boy 700 as described in section 6.1.
2. Pull the terminal upwards out of the terminal block and plug it into the
appropriate slot.
3. Plug the jumper provided in the accessories kit into the corresponding slot on the
controller board. If you want to use the Sunny Boy 700 with the maximum input
voltage range, then do not use the jumper.
4. Once the jumper is in place and the terminal plugged into the correct slot, close
the Sunny Boy 700 as described in section 6.2.

5.4 Startup
You can start up the Sunny Boy 700 when
• the lid is securely screwed on the enclosure,
• the AC (mains) cable is connected correctly,
• the DC cables (PV strings) are fully connected and the unused DC plug connectors
on the bottom of the enclosure are closed using the protective caps.
How to start up the inverter
1. First of all, switch the line circuit breaker to the
"on" position.
2. Check whether the LEDs indicate trouble-free
operation of the Sunny Boy 700 based on the
table on the next page. In that case, startup has
been successfully completed.

Check the string voltages again to make sure they are within the limits stated in
section 4.2 "PV generator requirements" (page 15). If the string voltages are too
high, the PV generator's planner / installer should be called upon for assistance.
If despite checking the string voltages the LED signal occurs again when the PV
generator is connected to the Sunny Boy 700, disconnect the PV generator from the
Sunny Boy again and contact SMA Technologie AG (see section 10 "Contact"
(page 49)).

8 Replacing the varistors
The Sunny Boy 700 is a complex high-technology device. As a result, the possibilities
for fixing faults on site are limited to just a few items. Please don't try to carry out
repairs other than those described here. Use the SMA Technologie AG 24-hour
exchange service and repair service instead.
If the red LED on the status display glows continuously during operation, you should
first of all make sure that there is no earth fault in the PV generator.
1. Disconnect the Sunny Boy 700 from the low
voltage grid (pull out the AC plug or switch the
line circuit breaker to its "off" position). Make
sure the grid cannot be inadvertently
reconnected.
2. Disconnect the DC plug connectors for all
strings. Make sure you note the order of the
individual inverter inputs so you can put them
back in the right place later!
3. Taking one DC plug connector at a time,
measure the voltages between one DC plug
connector of a string and earth potential. Pay
attention to the safety warnings!

Caution! Dangerous high voltages may be present. Danger of

4. If the measured voltages are constant and if their total is roughly the same as
the open circuit voltage of the string then there is a earth fault in this string. Its
approximate location can be deduced from the relationships between the
voltages.

Replacing the varistors SMA Technologie AG
5. Repeat points 3 and 4 for each string.
If you found a earth fault, it is probably not necessary to replace the varistors.
Instead, make sure the ground fault is fixed. Generally the PV generator's
installation engineer should be hired for this job. In this case continue as
described under point 10, but without reconnecting the faulty string. Instead of
reconnecting the string, protect its DC plug against accidental touch contact
(e.g. by fitting the protective caps or using sufficient high-voltage insulating
tape).
If you did not find any earth fault in the PV generators, it is likely that one of the
thermally monitored varistors has lost its protective function. These components
are wearing parts. Their functioning diminishes with age or following repeated
responses as a result of overvoltages. You can now check these varistors in the
following way, paying attention to the safety information in section 2 "Safety
information" (page 9):
6. Remove the screws that secure the lid and remove the lid from the Sunny Boy
700. Disconnect the PE connection from the lid. Make sure that no voltage is
present.
7. Using a continuity tester, check all the varistors to see if there is a conducting
connection between connectors 2 and 3. If there isn't, then that varistor is not
working. The positions of the varistors in the Sunny Boy 700 can be seen in
section 3.1 "Unit description" (page 11).
8. Replace the varistor concerned with a new one
as shown in the drawing to the right. Ensure the
varistor is installed the right way round! If you
do not receive a special tool for operating the

failure of one varistor is generally due to factors
that affect all varistors in a similar way
(temperature, age, inductive overvoltages), it is
highly recommended that you replace both

defective. The varistors were specially

SMA Technologie AG Replacing the varistors
In case there are no spare varistors available the Sunny Boy 700
still can feed electricity into the grid. The input is not protected
against overvoltages in this case. Replacement varistors should be
obtained as soon as possible. In systems with a high risk of
overvoltages, the Sunny Boy 700 should not be operated with
defective varistors.
9. Reconnect the PE connection on the lid and close the Sunny Boy 700.
10. Connect up the faultless PV generator strings to
the inverter.
11. Close off the unneeded DC input sockets using
the protective caps supplied in the accessories
kit.

If no earth fault and no defective varistor were found, there is probably a fault in the
Sunny Boy. In this case, contact the SMA hotline to discuss what to do next.

Required technical information for the inverters used:
• Maximum output current = 3.5 A
• Maximum permissible fuse protection for the inverter = 16 A
The choice of cable together with the way it is routed, ambient temperatures and
other underlying conditions limit the maximum fuse protection for the cable.
• In our example we assume that the chosen cable (2.5 mm²) is ideally routed and
can take a nominal current of 11 A.
Selecting a line circuit breaker:
• The maximum possible nominal current for the cable used and the maximum
possible fuse protection for the inverter now limit the maximum possible nominal
current for the line circuit breaker.
• In our example, 10 A is possible.
However, the thermal suitability of the line circuit breaker still needs to be checked.
Installation Guide SB700-11:SA2006 Page 45
Page 46
Rating for a line circuit breaker SMA Technologie AG
When selecting line circuit breakers, a number of load factors need to be taken into
account. These can be found in the respective data sheets.
Example for the thermal selection of a 10 A line circuit breaker with B sensitivity
with no gap between the circuit breakers:
For example, one manufacturer's circuit breaker may be designed for an ambient
temperature of 50 °C.
Load factors according to data sheet specifications:
• Reduction through permanent load >1h = 0.9
• Reduction when 9 circuit breakers are arranged side-by-side without
gaps = 0.77
• Increase in nominal current as a result of ambient temperatures of 40 °C in the
circuit breaker panel = 1.07
2
3
1
Result:
The nominal load current for the line circuit breaker is calculated as:
Ibn = 10 A x 0.9 x 0.77 x 1.07 = 7.4 A
1. Permanent loads of longer than 1 hour are possible in photovoltaics.
2. When only one circuit breaker is used, this factor = 1
3. Because the circuit breakers are rated for 50 °C
Page 46 SB700-11:SA2006 Installation Guide
Page 47
SMA Technologie AG Rating for a line circuit breaker
Summary:
The selected line circuit breaker can be used in our example case since the maximum
current-carrying capacity for fault-free operation is higher than the maximum output
current of the inverter used. It will trip under rated operating conditions!
If the calculated current-carrying capacity of the circuit breaker had been lower than
the maximum output current from the inverter, the following solution might have been
used:
By spacing the circuit breakers at an interval of 8 mm, the reduction factor would be
0.98 instead of 0.77. As a result, the maximum current-carrying capacity would
increase to 9.4 A.
As well as the thermal rating of the circuit breakers and all other factors as specified
in section "Rating for a line circuit breaker in a photovoltaic electrical power unit
operated in parallel with the low-voltage grid" (page 16), of course the applicable
DIN VDE standards
here are:
