6. Wiring the Inverter
6.1 Preparation before Wiring
1. To avoid accidents, please conrm that the PV inverter’s power of both DC and AC are
switched off.
2. Please conrm whether the input/output of PV inverter’s wiring are clearly indicated. Make
sure that the value, polarity, voltage and phase are correct.
3. The wiring procedure of a PV system is shown in gure 6-1 and 6-2. Wiring details are described in the following paragraphs.
– When the DC input is oating, an external transformer is not necessary. Please refer
to Figure 6-1 for the connection. The inverter can accept DC inputs in parallel (1 MPP
tracker) or separate DC input connections (2 MPP Trackers).
– When an asymmetrical DC load is detected, the solar inverter will automatically adjust
for optimum output. Please see section 6.3.1 for more details. This is useful where
there are two strings of modules on roof surfaces with different orientations, such as in
the case of a dormer with north & south facing surfaces.
CAUTION
Machine and equipment damage may occur.
► When the DC input is a positive ground or negative ground, all of the
strings must be connected in parallel and then connected to the inverters. In addition, an external isolation transformer must be installed on
the AC side, otherwise, damage will result and the inverter will not work
properly. Different DC input wiring needs require different insulation
detection settings. To learn more about the settings, please refer to
„6.3.6.2 Install Settings“ on page 54.

6.2.1.1 Residual Current Devices
The SOLIVIA 10 TL / 15 TL / 20 TL / 30 TL are not capable of feeding in DC residual currents due
to their design. They fulll this requirement in accordance with DIN VDE 0100-712.
The possibilities of faults were examined without taking the integrated residual-current monitoring
unit (RCMU) into account. When examining these faults in terms of the current valid installation
standards, no danger in combination with a type A upstream residual-current device can occur.
Therefore faults that would otherwise require the use of a type B residual-current device due to
the inverter can be excluded.
The integrated all-pole sensitive residual-current monitoring unit (RCMU) results in additional
safety. For all above mentioned transformerless inverters from Delta RCDs of the type A can be
used.

6.2.4 AC Wiring Considerations
The connection to the Amphenol AC connector for all models can be made with a exible or
rigid cable with a copper conductor that has the appropriate cross section according to table 6.1
and which has an installation condition that gives a correction factor equal to one. The AC cable
should be protected by a minimum type B 40 Amp breaker for 10 TL / 15 TL / 20 TL and minimum
type B 60 Amp breaker for 30 TL.
This connector is developed for connection to copper wires (for other applications please contact
Amphenol). The cross section of the cable should be calculated by considering the material used,
thermal conditions, length of the cable, the type of installation, and AC voltage drop.
Please note the cable length and the cable cross-section, due to the risk of undesirable temperature rise and power losses. In some countries, (e.g. France, Germany, Australia) system installation requirements have to be followed (UTE 15712-1, VDE 0100 712, AS/NZS 5033:2005). This
recommendation will dene minimum cable sections and protections against overheating due to
high currents. Please make sure that you follow specic requirements in your country.
For the security of your installation and for the safety of the user, please install required safety and
protection devices that are applicable for your installation environment (example: automatic circuit
breaker and/or overcurrent protection equipment).
WARNING
Death and serious injury may occur
In the case of damage or bodily harm resulting from the use of this device
in a way contrary to it’s intended purpose or as a result of unauthorized
modications made to the parameters of the inverter, Delta will not be held
liable in these situations..
The solar inverter must be grounded via the AC connector’s PE conductor. To do this, connect the
PE conductor to the designated terminal.
The AC connector is protected from unintentional disconnection by a clip mechanism which can
be released with a screwdriver.
The AC voltage should be as follows:
● L1-N: 230 V

7.3.6.5 Reactive Power Control for Slovenia (SONDO) for 15 / 20 / 30 TL Models
When selecting Slovenia from the Country setting list on initial start up, it is possible to adjust
reactive power parameters for Q(V) according to two curves, class B and class C. The Slovenian
requirements are known as SONDO or SOIEDN (System operation instructions for electricity
distribution network). Q(V) is the reactive power ratio Q/S
n
in dependency of the voltage V.
CAUTION
Machine and equipment damage may occur.
► Please only adjust these reactive power settings if you are a qualied
electrical technician with the knowledge to do so
► Adjustments may affect energy production
► Some values entered in the Reactive Power settings must come from
the local grid operator. Please check with them before making any
adjustments
NOTE
The inverter is only able to feed-in reactive power in Class B or Class C set-
tings when the Power output is greater than 5% of Pn.

8.2 Replace a Fan
If one of the fans has failed and needs to be replaced, user should remove the 4 screws (circled
below) that attach the fan to the fan bracket. Next, pull the fan slightly away from the bracket and
disconnect the fan connector located behind the fan bracket. The fan can now be removed and
replaced with a new fan. Follow the procedure in reverse to install the new fan. (Figure 8-2 illus-
trates the replacement of the rst fan on the fan bracket. Call the support hotline for assistance in
procuring a replacement fan.
Note: The fan bracket shown is
for the 15 TL, 20 TL, and 30 TL.
The 10 TL fan bracket will have
just one fan. The procedure to
replace the fan on the 10 TL will
be the same.
