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!
Danger
All installation operations must be carried out by a professional electrician,
who must:
•be prepared.
•carefully read this manual and understand its contents.
Warning
Before connecting the inverter to the grid, make sure that all the necessary
permits have been obtained from the local grid operator and that all the
electrical connections are made by a professional electrician.
Attention
Do not remove the information label or open the inverter.
Otherwise, ZCS will not provide any warranty or maintenance.
Note
Operation
Contact with the electrical grid or the terminal of the equipment may cause
electrocution or fire!
•Do not touch the terminal or the conductor connected to the electrical grid.
•Follow all the instructions and safety requirements relating to the mains
connection.

Some internal components reach very high temperatures when the inverter
is in operation. Wear protective gloves!
Attention
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 these actions.
Attention
EMC/Noise Level
Electromagnetic compatibility (EMC) refers to that on electrical equipment functions in a given
electromagnetic environment without any trouble or error, and impose no unacceptable effect upon the
environment. Therefore, EMC represents the quality characters of an electrical equipment.
-The inherent noise-immune character: immunity to internal electrical noise.
-External noise immunity: immunity to electromagnetic noise of external system.
-Noise emission level: influence of electromagnetic emission upon environment.
Electromagnetic radiation from inverter may be harmful to health!
Please do not continue to stay away from the inverter in less than 20cm
when inverter is working

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; which must be below the maximum
allowable DC voltage. Overvoltage can cause permanent damage to the
inverter or other faults which are not covered by the warranty!
Warning
Symbols on the inverter
Some safety symbols are located on the inverter. Read and understand the contents of the symbols before
installing the inverter.
After disconnect with the DC side, there is a residual voltage in the inverter,
operator should wait for 5 minutes to ensure the capacitor is completely
discharged.

2.2. Description of functions
DC power generated by PV arrays is filtered through Input Board then enter Power Board. Input Board also
offer functions such as insulation impedance detection and input DC voltage/ current detection. DC power is
converted to AC power by Power Board. AC power is filtered through Output Board then AC power is fed
into the grid. Output Board also offer functions such as grid voltage/ output current detection, GFCI and
output isolation relay. Control Board provides the auxiliary power, controls the operation state of inverter
and shows the operation status by Display Board. Display Board displays fault code when inverter is
abnormal operation conditions. At the same time, Control Board can trigger the replay to protect the
internal components.
Function Module
A. Energy management unit
Remote control to start/ shunt down inverter through an external control.
B. Feeding reactive power into the grid
The inverter is able to produce reactive power thus to feed it into the grid through the setting of the
phase shift factor. Feed-in management can be controlled directly by APP or through a RS485 interface.

C. Limited the active power fed into grid
If enable the limited of active power function, inverter can limit the amount of active power fed into the
grid to the desired value (expressed as percentage).
D. Self-power reduction when grid is over frequency
If grid frequency is higher than the limited value, inverter will reduce the output power to ensure the
grid stability.
E. Data transmission
Inverter can be monitored remotely through an USB stick logger (WIFI/Ethernet/GPRS) or software
Storage Monitor(optional) which is based on RS485 interface.
F. Software update
USB interface for uploading the firmware, remotely uploading by using USB acquisition stick
(WIFI/Ethernet/GPRS) is also available.
2.3. Electrical block diagram
3PH 60KTL-800KTL-V3 has 12 DC input strings, 6 MPPT trackers to tracking the
maximum power point, then converters the direct current of PV array to grid-compliant, three phase
current and feeds in into the utility grid. Both DC and AC side has Surge Protection Device (SPD).
