Installation requirements
Install and start the inverter according to the following instructions. Place the inverter on suitable load-
bearing supports with sufficient load capacity (such as walls or photovoltaic racks) and make sure that the
inverter is positioned vertically. Choose a suitable location for the installation of the electrical equipment.
Make sure there is sufficient space for heat dispersion and to accommodate future maintenance. Maintain
adequate ventilation and ensure that there is enough air circulation for cooling.
Figure 1 –Do not lose or damage this manual
Transport requirements
If you have problems with the packaging that could damage the inverter or if you find any visible damage,
immediately notify the transport company. If necessary, request assistance from an installer of photovoltaic
systems or from Zucchetti Centro Sistemi SpA. Transport of the equipment, especially by road, must be
carried out with vehicles suitable to protect the components (in particular, electronic components) against
violent knocks, humidity, vibrations, etc.
Electrical connections
Please pay attention to the electrical regulations on accident prevention when dealing with photovoltaic
inverters.
Before connecting the mains power, be sure to disconnect the photovoltaic
modules by disconnecting all the DC switches of the generator. When
exposed to the sun, the photovoltaic panels produce a voltage that can be
dangerous!

Maintenance and repair
Before carrying out any repairs, disconnect the inverter from the mains network (AC
side) and from the photovoltaic system (DC side).
After switching off the AC and DC switches, wait 5 minutes before carrying out any
repairs or maintenance on the inverter!
Danger
The inverter should start working again after any faults have been fixed. For any
repairs, contact your local authorised service centre;
Do not disassemble the internal components of the inverter without permission. This
will void the warranty. Zucchetti Centro Sistemi S.p.A. shall not be responsible for any
damage or loss caused by improper use or maintenance.
Attention
1.2. Symbols and icons
Safety signals
Pay attention to possible burns due to hot parts. Only touch the screen or
press the keys while the inverter is in operation.
Caution
The PV strings should be connected to the ground in accordance with the local
regulations.
To ensure the safety of the system and people, the inverter and photovoltaic
strings must be securely connected to the ground.
Attention
Ensure the correct DC input voltage; this must be below the maximum
allowable DC voltage. Overvoltage can cause permanent damage to the
inverter that is not covered by the warranty!

Product dimensions
The field of use and overall dimensions of the 1PH 1100TL-3300TL-V3 inverters are indicated in this
section.
Description of functions
Describes how the 1PH 1100TL-3300TL-V3 inverters and their internal operating modules work.
Efficiency curve
Describes the efficiency curves of the inverter.
2.1. Product presentation
Field of use
The 1PH 1100TL-3300TL-V3 inverters are grid-connected photovoltaic inverters with a single MPPT
channel, capable of converting the direct current generated by the photovoltaic strings into single-phase
sine wave alternating current and feeding the energy to the public electricity grid. An AC circuit breaker
(see chapter 4.4) must be used as a disconnecting device and must always be easily accessible.
Figure 2 –Grid-connected photovoltaic system
The 1PH 1100TL-3300TL-V3 inverters can only be used with photovoltaic modules that do not require one
of the polarities to be grounded. The input current and voltage of the PV strings must not exceed the limits
specified in the technical specifications. Only photovoltaic modules can be connected to the input of the
inverter (do not connect batteries or other power supply sources).
• Accessories and optional components of the inverter should be chosen by a qualified technician who is
familiar with the installation conditions.

2.2. Description of functions
The DC power generated by the PV modules is filtered through the input board before entering the power
board. The input board also has the function of detecting the insulation impedance and the DC input
voltage/current. The power board converts the DC power into AC power. The current converted into AC is
filtered through the output board and is then fed into the grid. The output board also has the function of
measuring the grid voltage/current, GFCI and acts as an output isolation relay. The control board provides
the auxiliary power supply, controls the operating status of the inverter and shows it on the display. The
display also shows the error codes when the inverter is not functioning properly. At the same time, the
control board can activate the protection relay in order to disconnect the inverter from the grid and protect
the internal components.
Inverter functions
A. Feeding reactive power into the grid
The inverter is able to produce reactive power and feed it into the grid through the setting of the Power
Factor. The feed-in management can be controlled directly by the grid company through a dedicated RS485
interface.
B. Limiting the active power fed into the grid
If enabled, the inverter can limit the amount of active power fed into the grid at the desired value (expressed
as a percentage).

C. Automatic power reduction when grid is over frequency
When the grid frequency is higher than the limit set, the inverter reduces the output power in order to
ensure the stability of the grid.
D. Data transmission
The inverter (or a group of inverters) can be monitored remotely via an advanced communication system
based on a RS485 interface or via Wi-Fi.
E. Software update
A microSD card is used to update the firmware.
