Manufacturer's warranty - Warranty on products in the SUNSYS HOME series
Sicon S.r.l., a member of the Socomec group which deals with the supply, control and safety of low voltage electrical networks, with
registered head office in via Sila 1/3 – Z. I. Scovizze, 36033 Isola Vicentina (VI), guarantees that its products in the Sunsys Home
series are new and adhere to the applicable technical specifications and quality standards.
1) Conditions of Warranty
Sicon S.r.l. guarantees its products in the Sunsys Home series for a period of 5 years from purchase, for manufacturing or
material defects only.
The warranty period runs from the date on which the new product was purchased by the end user at the showroom of an official
dealer (the reference data is that indicated on the proof-of-purchase document).
The warranty covers:
a) the free repair or replacement of the product or of the faulty component, but with the expenses for installation of the product
or of the replacement component borne by the customer or by the end user;
b) sending the faulty product to Sicon S.r.l. (or to authorised centres) with uninstallation, transportation and related expenses
borne by the customer or by the end user;

2. PRODUCT DESCRIPTION
The inverter is a photovoltaic inverter for conversion of direct current into alternating current in line with the mains network. In
accordance with local and national regulations, in the event that excess energy is produced it can be sold to the local electricity
supply company or credited in anticipation of future consumption; if not much energy is obtained from the photovoltaic system, it
will be drawn from the mains network instead, to ensure that household utilities continue to run normally. The operating principle is
illustrated in figure 2.1.

2. PRODUCT DESCRIPTION
This version of the inverter does not have a transformer, i.e. there is no galvanic insulation between the input and output; it must
therefore be used with panels which do not have an earth connection conforming to standard IEC61730, class A. Large capacity
photovoltaic modules may only be used if the coupling capacitance to ground is lower than 100 nF/kWp. The earth leakage current
(whose value depends on the type of module-mounting structure used as well as the prevalent meteorological conditions) should
not exceed 150 mA.
The application of cutting-edge technology allows a large electrical and thermal operating interval. The advanced MPPT control
system, the high efficiency levels, the wide voltage range of the PV field and the ability to manage transitory power peaks greater
than the rated power supply, all help to provide maximum photovoltaic energy in every condition. Plus, thanks to its high IP class and
innovative temperature control, the inverter can be placed outdoors. To achieve the best performance levels, the recommendations
provided in this manual should always be observed.
The inverter has additional functions to satisfy current regulations and to help stabilise the mains distribution network to which it is
connected.
These functions include:
• Reactive power management.
• Power adjustment in accordance with network parameters.
• Non-sensitivity to voltage drops (LVFRT capability).

INSTALLATION
3.4. Choosing the installation site
The inverter installation site must be chosen on the basis of the following criteria:
• The inverter must be positioned at a height which allows easy viewing of the display and the LEDS status.
• Install the unit in well-ventilated areas and away from direct sunlight.
• Do not install the unit next to or above flammable objects.
• Do not install the unit in particularly busy areas, or where people can come into contact with the equipment easily.
• Mount the unit by fixing it securely to a solid wall.
• The protective panel underneath the right-hand part of the guard cover must be removed in order to replace the clock battery,
access the communication port and update the software as necessary.
Enough space must therefore be left underneath the inverter so that this side and the connections can be accessed easily.
3. INSTALLATION
3.3. Identifying the inverter
The inverter can be identified using its data plate, located on the right-hand side of the radiator (see figure 3.3-1).
3.3-1 ID label
The model, series number and main specifications are
specified on the label.

3.5. Wall-mounting
This inverter is designed for mounting on masonry walls. If the walls are made using different materials, the installer must use suitable
mounting supports. The mounting bracket dimensions are indicated in the figure below. Fix the bracket (supplied) securely to the
wall before hanging the inverter on it.
WARNING!
Mount it vertically or at a maximum angle of 45° (see figure 3.5-2). Be careful, as in this case a drop in performance
(derating) may occur due to the deterioration of heat dispersal.

3. INSTALLATION
WARNING!
Make sure the electrical installation and the system comply with relevant national regulations.
The diagram of a typical inverter installation is illustrated in figure 3.6-1.
DANGER!
Risk of electric shocks from live device parts!
The inverter can be connected to two separate power sources:
• DC cable – Power from the photovoltaic generator
• AC cable – Power from the mains network, supplied by the electricity company
Before carrying out any work, make sure the electricity sources have been disconnected.

3.5.1. Network disconnection
A protection and disconnection system for the AC network should be installed on the fixed switchboard.
For correct installation, we recommend using a C curve 16 A thermal-magnetic switch.
3.5.2. Photovoltaic field disconnection
WARNING!
Before carrying out any photovoltaic field connection procedures, make sure the DC power switch is disconnected.
To prevent risks to operators and systems resulting from incorrect handling (opening of the switch when charged), we recommend
the use of DC switches capable of opening the circuit at the maximum specified PV field short-circuit current and voltage levels
(check the values in the technical data table).
3.5.3. Protection against fault currents
The inverter is fitted with a unit which monitors and detects fault currents; this is sensitive to all types of ground fault current.
We recommend the application of an external type A 30 mA differential protection device with low sensitivity (S).
The differential protection device to be used may depend on the photovoltaic field installed, that is the equivalent parasitic capacity
of the photovoltaic modules in relation to earth. In fact, during operation, a current is created and discharged to earth; its value
depends on the type of module mounting used (structure, expanse, type of panels) and the meteorological conditions (rain, snow,
humidity...). If the equivalent parasitic capacity between the modules and earth is high (in general, over 200 nF) it may be necessary
to use a differential device which triggers at fault currents over 100 mA.
3.5.4. Protection against transitory over-voltages
The inverter is designed for transitory over-voltages in category II installations for AC terminals. If the inverter may be subjected to
transitory over-voltages in category III installations, protective SPD dischargers must be provided for the AC power supply network.
If the photovoltaic panels are more than 10 metres away from the inverter, we recommend SPD dischargers are also installed on
the DC side.

17
SUNSYS H30-H30i - Ref.: IOMSUNHMXX04-GB 00
ENGLISH
For safety reasons, the equipment must always possess an earth connection, which in any case must also be the last connection
to be disconnected.
4. WIRING
WARNING!
The inverter must only be connected to the mains electricity network by qualified operators after the appliance has
been securely fixed to the wall.
Before carrying out any electrical connection or system maintenance procedures, the following checks must be
performed:
• Make sure that both disconnection switches (DC and AC) are open (OFF).
• Make sure the photovoltaic system cannot be restarted.
• Cover the panels with radiation blocking material (preferably black in colour).
• Make sure there is not electrical voltage being supplied from the mains network or the photovoltaic field.
Any non-conforming procedure could place the operator in a hazardous situation and may damage the equipment.
WARNING!
Always observe the rated voltage and current values specified in the design phase of your system. It is especially impor-
tant to observe the maximum voltage and current values for the photovoltaic field (see "Technical data" chapter).
4.1. Earth wire connection
DANGER!
Risk of electric shocks from live device parts!
The inverter can be connected to two separate power sources:
• DC cable – Power from the photovoltaic generator
• AC cable – Power from the mains network, supplied by the electricity company
Before carrying out any work, make sure the electricity sources have been disconnected.
Before connecting to the mains network and photovoltaic field, the inverter should be earthed using the connection point on the
casing. The wire must have a cross-section which is at least equal to that of the phase wire in order to guarantee optimal conductivity.
Correct connection is illustrated in figure 4.1-1.

4.2. Mains connection (AC)
DANGER! Risk of serious injury and even death.
Before carrying out any AC mains network connection procedures, make sure the AC power is disconnected.
Size the cross-section of the wires in the AC cable so that line losses are minimised at rated power (see maximum AC current in the
"Technical data" table). We recommend using wires of at least 2.5 mm2. The AC connector supplied allows wires up to 6 mm2, with
an external insulation diameter not exceeding 12 mm.
4.2.1. Connection procedure
Take care to perform wiring correctly, observing the polarities.
I - Unscrew the connector in three parts: A, Band C(Fig. 4.2.1-1).
II - Run the cable through Band C.
Strip the wires
Secure the wires as indicated below, taking care to observe the polarities:
- Insert the earth wire (PE) corresponding to the relevant symbol
- Insert the phase wire (L) corresponding to terminal 1
- Insert the neutral wire (N) corresponding to terminal 2
III - Screw the plug together in the order indicated: Awith Band Bwith C.
IV- Plug the connector into the appropriate AC input on the inverter.

4.3. Photovoltaic field connection (DC)
DANGER!
• Risk of serious injury and even death!
•
Before carrying out any photovoltaic field connection procedures, make sure the DC power switch is disconnected.
Use suitable cables for connection to the photovoltaic field. Size the cross-section of the wires in accordance with the maximum
photovoltaic field short-circuit current and so as to minimise cable conduction losses. The DC connectors supplied allow PV1-F
cables with a maximum cross-section of 6 mm2.
WARNING!
The DC connectors are polarised. Take care to perform wiring correctly, observing the polarities.
Figure 4.3.1-1 illustrates how to connect the positive pole of the photovoltaic field to the corresponding DC+ connector. The negative
pole can be connected in the same way.
4.3.1. Connection procedure
1 Unscrew the cable gland for the relevant DC connector and run the cable (which should have been stripped at the end by approx.
15 mm) through it.
2 Insert the cable into the connector as far as it will go.
3 Press the terminal downwards until it clicks into position.
4 Make sure the cable is fixed in position securely. The cable is properly secured if the wires can be seen inside the terminal chamber.
5 Push the screw connection onto the threading.
6 Screw on the cable gland.
7 Plug the connectors into the appropriate DC inputs on the inverter.
