2.2 Lighteningandovervoltage
Inareaswherestormsarefrequent,electricaldischargescanoccurthroughthemains.
It may therefore be advisable to install lighting conductors to protect the appliance control circuits from
anydamagethatmightoccurduetohighvoltagesinthesurroundingatmosphere.
To protect the inverter from voltage peaks caused by atmospheric discharges, it is advisable to install
varistorsontheinputconnectionlines(modules)andontheoutputlines(alternatecurrent)ofthesystem.
To protect the appliance from direct lighting strikes, both lightning rods and special protective devices
shouldbeinstalled.
2.3 Groundconnection
The inverter must be grounded for compliance and as required by current regulations concerning low
voltage.Allthecomponentsoftheinstallationmustbegroundedtothesamesystem.
The first cable to be connected should always be the ground cable. When disconnecting the appliance,
alwaysleavetheearthcabletolast.

3 DESCRIPTIONOFTHEEQUIPMENT
3.1 Introduction
The SOLEIL DSPX range of inverters provides the ideal solution for connecting photovoltaic power
productionsystemstothreeͲphasepowergrids.
The series is composed of inverters with an isolation transformer (SOLEIL DSPX: TRL, TRH and TRW) and
transformerlessinverters(SOLEILDSPX:TLWandTLH).
The inverters of the SOLEIL DSPX series are in compliance with the resolution AEEG 84/2012/R/ENEL
(attachmentA70ofTERNA,CEIͲ021,andCEIͲ016)
All inverters use a system which tracks the maximum power point of the photovoltaic generator (MPPT)
thusachievingthemaximumpowerefficiencyinanyoperatingstatus.
SOLEILDSPXinverterspermitbothautomaticandmanualoperation.Inautomaticmode,maximumpower

Thewaveformofthe currentinjectedintheelectricitydistributiongridisidenticaltothatofthevoltage

Thedeviceisalsoequippedwithtwocommunicationports,whichcanbeconfiguredaccordingtodifferent
serialtransmissionstandards,andwitha“voltfree”contactterminalboardfortheremotesignallingofthe

Pulse width modulation (PWM) control technology and IGBT power devices are used on SOLEIL DSPX
inverters, which permit the switching of significant levels of power with a high degree of sturdiness and
reliability.

3.3 Operatingprinciples
When the inverter is energized, the control system checks the power grid, voltage and frequency
parameters. If these parameters are within the correct range, the inverter checks the voltage of the
photovoltaicgeneratorandwhenthisreadingissufficientlyhigh,theconversionprocessbegins.
When the photovoltaic field voltage reaches the right level, the grid contactor closes and the inverter
beginsdeliveringpowertothethreeͲphasepowergrid.
At this point, the control system starts varying the photovoltaic generator’s operating point to track the
maximumpowerpoint.Thistrackingtakesplaceatintervalsofabout2seconds.
If the grid voltage and frequency values are within the range of acceptance established by legislation, in
conditionsoflowirradiation(DCvoltagebelowtheminimumthreshold,seechapters7and8,orthepower
injectedintothegridisbelowacertainthreshold),theinverterentersintostandbymodefor6minutes.
After this pause, if the photovoltaic generator and grid parameters are correct, the inverter starts up
automaticallyrecoveringtheconversionprocess.
If the test detects abnormal operating conditions which can jeopardize machine reliability, adequate
protections are activated. After the activation of a protection, the control system waits 10 seconds and,
accordingtothe“severity”leveloftheprotection,itmaydecidetorestarttheinverterortostopituntila
repair is carried out by the SIEL technical service. For more details about alarms and protections, see
paragraph4.5.2.

Theevolutionofthemaximumpowerpoint(G)isalsoshownonthecurves.
Therefore, the purpose of the maximum power tracking algorithm (Maximum Point Power Tracker) is to
vary the device’s load resistance to ensure the constant functioning of the photovoltaic system (panel +
inverter)inthehighestpossiblepointofpower;inthiswaythemaximumlevelofpowerwillbedelivered
tothepowerdistributiongrid.
Inautomaticmode,theinverterconstantlytracksthemaximumpowerpoint
The device can also be operated in Manual mode, during which the user determines a fixed operating
point.Obviously,themaximumlevelofpowerefficiencyfortheinstallationisnotachievedinthismode;
for this reason, manual operation must only be used as a method of checking the device by trained
technicalpersonnel.

Thetypeandtheimplementationofanyairdistributionlinemustbechecked
and approved by Siel SPA. The manufacturer is not in any way liable for
inverter malfunctions due to the failure to observe the rules of Installation,
particularly the permitted temperature and humidity requirements. It is
recommended therefore to adopt design features (for example airͲ
conditioning, heating or dehumidification of the premises), suitable to
guarantee the maintenance of the permitted temperature and humidity
conditions.
6.5 InstallationLocationofinverters
The inverter must be installed on a stable, level surface that is longer and wider than
thebaseoftheappliance.
The inverter is not designed to be installed in areas where it could be exposed to
impacts or vibration: being transported by road, rail, sling, air or ship or by similar
equipment(e.g.cranes,movingpartsoftheapplianceetc.).

6.6 InstallationLocationofoutdoorinverters
The inverter must be installed on concrete reinforced basement, such to stand the
weight of the inverter. The basement has to be prepared with cable conduits and
fixation holes before the installation. The inverter has to be secured to the basement
throughdedicatedscrewsinsertedintothefixationholes.
The inverter is not designed to be installed in areas where it could be exposed to
impactsorvibration.
6.7 POSITIONINGANDVENTILATION
Although “SOLEIL DSPX” series inverters are highly efficient, be aware that during
normal operation a certain amount of heat is generated. If this heat is not properly
dissipated, it can lead to an increase in temperature in the room where the inverter is
locatedandsotheinverteritselfcanstarttooverheat.

A set of 3 additional fans is available on request to increase the machine
coolinginsevereenvironmentalconditions.
The installation of this set requires the connection of a dedicated 230Vac,
50Hz line with the L, N terminals of the inverter. The cables for the external
fanpowerareincludedintheset.Themountinginstructionsforthesetareas

It is strongly recommended to replace capacitors AC side and DC before the end of life expectancy (10
years).Thisactivity,duetoitscomplexity,requiresbeingdonebyqualifiedpersonnel.
Replacement of fans is better done at intervals of five years, to prevent their failure or performance deͲ
ratingduetotheagingofitscomponents(rotor,winding,bearings,etc.)
All the above operations and access to the internal components have to be carried out by trained
technicians.

generationofreactivepowerdisabled(p.f.equalto1).
x Rated power at p.f. = 0,9P*: maximum active power distributable on conditions of nominal grid
voltageandgenerationofreactivepowerenabled(p.f.between0,9and1).
x PowermaximumSmax:maximumpowerapparentdistributableonconditionsofmaximumactive

4. Voltagedefinitions
x Min Smax operating voltage: minimum voltage at which the Smax generation of the maximum
powerispossible.
x Min operating voltage: from 90%Vn to 85%Vn the inverter operates within the limitation of the

Reactive power generation Q = f (Vac), according to that required by appendix A68, requires voltage
referencebethosedirectlyreadatthedeliverypointontheHV/HHVgrid.
To run this function for HV/HHV connections, efficient phase voltage values must be acquired through
another system independent of the inverter and communicated to the latter via RS485 communication
usingMODBUSprotocol.
