SafetyNotes

PleasecarefullyreadallwarningsandONLYinstalltheitemwhenyouaresurethat
you’vecoveredallaspects.

PotentiallydangerousHighVoltagesarepresentandthereforethis
equipmentshouldonlybeinstalledbyaqualifiedperson.

ConnecttheequipmentaccordingtothecorrectIEEregulationsandseparate
allwiringaccordingtoIEC1010.

Earthmustbeconnectedforsafetyandcorrectoperation.

AsuitablemeansofisolatingSOLARIMMERSIONIVfrombothpolesofthe
mainssupplyshallbeprovided.

Makesureallscrewterminalsaretightbeforeyouswitchtheequipmenton.
(Theterminalscrewisrated0.5N•mtorque)

Donottouchanycircuitryafteryouhaveconnectedtheequipment,dueto
potentiallylethalvoltagesonthecircuitboardandconnectorterminals.

FittopcoverbackbeforeswitchingontheMains.

EquipmentdesignedforPollution–Degree2environmentsonly.Thismeans
youmustinstallitinaclean,dryenvironment.

Overview

SOLARIMMERSIONIVisanintelligentsurpluspowercontrolsystemforyourPVsystem.Itdiverts
surpluspowerwhichwouldnormallybeexportedtothegrid.Whentheunitisconnectedtoan
immersionheater,itcanheatwaterforfreeusingthesurpluspower.


SOLARIMMERSIONIV‐Highlights:

Heatswaterusingsurpluspowerfromallsortsofmicro‐generationsystems(windturbines,
hydropower)
Keepsexportedpowerasclosetozeroaspossiblebyadjustingpowerlevelstotheimmersion
heater.
Singlesensorclip.
LCDdisplayforeasycontrolandmanagementoftheunit
Noneedtochangeimmersionheaterorthetank.
Nomanualinterventionrequiredtousesurpluspower.
Built‐inoverrideandboosttimerfunctionstoanimmersionheatermanuallyifrequired.
Lowthresholdlevelsmeaning,lesswastedpower.
Divertsaslittleas20Wofsurpluspower
Built‐inmultifunctionrelayforSecondload.
Internalthermalprotection
Multipleloadsavailable

3.Installation

Mounting

Tokeeptheinstallationquickandeasy,werecommendthatSOLARIMMERSIONIVisinstallednear
totheconsumerunitasmostoftheconnectionsrequiredcanusuallybefoundthere.

WhenchoosingasuitableplacetoinstallSOLARIMMERSIONIV,thefollowingshouldbe
considered:

Nearthemainincomingmainssupplyoftheproperty
Accesstotheimmersionheatersupplycable(normallyintheconsumerunit)
Accesstosuitablesupplyvia16AMCBor13Afusedoutlet
EaseofaccessandvisibilityoftheSOLARIMMERSIONIVLCDScreenandcontrolbuttons
Goodventilationtokeepairflowingthroughtheunit–atleast100mmaroundtheunit.
Suitablecableaccesspointlocation–throughthetopoftheunit

SecuretheSOLARIMMERSIONIVtothewallwiththetwoscrewsorusingsuitablefixingsforthe
surfacetype.

ElectricalInstallation

ATTENTION!
Electricalconnectionshouldonlybemadebyaqualifiedperson.
PleasedonotattempttoinstallSOLARIMMERSIONIVunlessyouholdsuchqualificationsorare
anexperiencedelectrician.Alterationstofixedwiringand/oropeningtheconsumerunitmay
berequired–riskofdeathbyelectrocution.

Locatethemostappropriatecableaccesspointattopoftheunittomakeconnectionstotheunit
accordingtothewiringdiagram.

Loads

Theproportionallycontrolledprimaryorsecondaryloadconnectedshouldnotexceed3.5kW.
Theloadshouldnotincludedigitalcircuits,astheymaybeaffectedbythemodulatedoutput
fromtheSOLARIMMERSIONIV.

SensorClipInstallation

Thecorrectinstallationandpositioningofthecurrentsensorclipisveryimportantfortheefficient
operationofSOLARIMMERSIONIV.Wronglyinstallingthesensorclipcouldresultinimportingof
powerandtheuserincurringadditionalcostsforelectricity.

Thesensorclipshouldbeinstalledatthemainincominggridsupplytothebuildingwhichcouldbe
fromtheutility/electricitymeter.(Pleasenote‐itisUtility/ElectricitymeterNOTthePVgeneration
meter).ClosethecliparoundtheLiveorNeutralcablefromtheutility/electricitymeter.Please
ensurethesensorclipispositionednearesttotheutility/electricitymeteraspossible.(Onlyopen
aconsumerunitifyouarequalifiedtodosoorareanexperiencedelectrician).

Ifthereismorethanoneconsumerunit,theclipmustbepositionedattheprimaryincomesource


Oncetheunitiswired,SOLARIMMERSIONIVhastobeconfiguredwiththeparametersrequired
fortheparticularinstallationtypeused.Bydefault,forsimpleinstallationswithasingleheater,the
onlyconfigurationrequirementsarelistedbelow.

Followthestepsbelowtocalibrateandsetuptheunit.

Step1:TurnoffthePVormicrogenerationsystem.Thisistomakesurepowerisonlyimported,
whichisessentialforsensorclipcalibration.

Step2:TurnonSOLARIMMERSIONIVunit.

Step3:Turnonahighloadlikeakettleora2kWheatertomakesurepowerisimportedandwait
for5seconds.




3b:Ifthedisplayisasbelow,thenyouhavetoswapthewiringontheCTsensorterminals.
Oncetheterminalsareswapped,restarttheswitchandmakesurethedisplayisaspicture




Step4:Setthecorrecttime&softwaresettingsaccordingtothewiringmodeselected.(Please
