SUNSYS P33TR - P66TL/TR - P100TL/TR - Ref.: IOMSUNMOXX00-GB 03
ENGLISH
The SUNSYS P series covers a range of power from 33.3 to 100 kW and consists of 1, 2 or 3 modules of 33.3 kW each.
Each module converts the energy provided by the solar panels, using a Maximum Power Point Tracking (MPPT) algorithm to fully
exploit the features of the photovoltaic cells.
The DC terminals of all modules can be connected to the same photovoltaic field (centralised modular inverter with single MPPT),
or can have different photovoltaic fields (centralised multi-string inverter with separate MPPTs).

2.2-12 Load sharing 2.2-13 Load sharing + Energy saver
In the case of the centralised modular inverter, the 33.3 kW modules run on Energy Saver mode.
This type of operation has two advantages:
• Longer equipment lifetime, as the individual modules are switched on and off at random and run for less time on average, instead
of all being switched on and off at the same time.
• Increased efficiency, as only the equipment actually required is activated and operates under optimal efficiency conditions (30-60%
of rated power).
In the case of centralised multi-string inverters, the MPPT algorithm of each module runs independently to maximise the power
supplied by the photovoltaic panels.
The inverter is equipped with an isolation transformer as standard, and can therefore be used with all photovoltaic panel technology
(crystalline, thin film, back contact etc.). For technology which requires one of the photovoltaic generator poles to be earthed, the
special optional kit (GND) must be used.
2.2.1. Options
SUNSYS P can be ordered together with the following options:
• Earthing: PV generator + or – pole earthed (GND)
• Permanent isolation controller (IMD)
• AC over-voltage dischargers (SPDO)
• DC over-voltage dischargers (SPDI)
• Cable fastening brackets
For detailed information regarding the options refer to the relevant documentation.

SUNSYS P can be connected to a maximum of three power supplies:
1 DC cable - Photovoltaic generator power supply (separated for the three modules or shared)
2 AC cable - Power from the mains network, supplied by the electricity company
3 AC cable - Auxiliary power supply
• Before carrying out any work, make sure the electricity supply has been disconnected.
• All DC power supplies should be considered as part of the same circuit, even in the configuration with centralised multi-string
inverter. Before carrying out any work, make sure all electricity supplies have been disconnected.
DANGER!
Risk of electric shock from live device parts!
The intermediate inverter circuit may be live even after it has been deactivated.
• Wait 5 minutes for the power to disperse and make sure that there is none remaining.
DANGER!
Risk of electric shock from live device parts!
The photovoltaic modules are live as soon as they are exposed to sunlight.
• Take suitable measures and make sure there is no power remaining.
SUNSYS P are designed for instant application. Only the AC and DC cables coming from outside must be installed and the inverter
configured.
5.1. ELECTRICAL INSTALLATION REQUIREMENTS

WARNING!
The inverter is designed for transient over-voltages in category II installations for AC terminals. If the inverter may be
subjected to transient over-voltages in category III installations, protective SPDs must be provided for the AC power
supply network. The SPDO option, designed to protect against category III over-voltages, can be fitted directly to
the inverter. If it is used, the distance between the inverter and type I centralised SPD protection must be ≥15 m.
WARNING!
The inverter is designed for transient over-voltages in category II installations for DC terminals. If the inverter may
be subject to transient over-voltages in category III installations, or if the distance from the SPDs in the photovoltaic
field is excessive, protective SPDs must be fitted near the inverter. The SPDI option, designed to protect against
over-voltages in photovoltaic applications, can be fitted directly to the inverter.
NOTE
DC inputs do not require protection against over-voltages, if fewer than three inverter modules are connected to
the same photovoltaic generator.
NOTE
Functional panel earthing (optional): for correct operation, some types of photovoltaic panel require one of the two
poles to be earthed. The special optional kit (GND) can be used to earth the positive or negative pole of the photo-
voltaic generator. For further details and instructions, please refer to the kit (GND) installation and operating manual.
IT SYSTEM
With the photovoltaic panels isolated from earth, the circuit consisting of the panels and the inverter is configured
like an IT system. We therefore recommend a permanent isolation controller is used in the system or built into the
inverter (IMD option).
