The SolarEdge Electricity Meter
TheSolarEdgemeterenablesmeasuringthepowerandenergyofthephotovoltaic(PV)system.
Themeterisusedbytheinverterforthefollowingapplications:
lConsumptionmonitoring
lExportlimitation
lStorEdgeSmartEnergyManagementon-gridapplications
ThemeterisbuiltintoanenclosureandrequirestwoCurrentTransformers(CTs;availablefrom
SolarEdge).
TheSolarEdgeinverterortheControlandCommunicationGateway(CCG)readstheexportedpower
fromameterinstalledatthegridconnectionpointorreadstheconsumptionfromameterinstalledat

Meter Connection Options
Inasingleinvertersystem,themeterisconnecteddirectlytotheinverter.Ifyourinverterhasabuilt-in
revenuegrademeter(RGM;theinverterisreferredtoarevenuegradeinverter),youcanconnectan
externalmeteronthesamebusastheRGM(availableformSolarEdge).
Figure 4: Single-inverter connection
Inamultipleinvertersystem,twooptionsareavailable:
lThemeterisconnectedtotheRS485portofoneoftheinverters.Inthiscase,astheinverter'sRS485
portisoccupiedbythemeter,useanRS485ExpansionKit(availablefromSolarEdge)orZigBee
communicationbetweentheinverters.
lThemeterisconnectedtooneoftheRS485portsofaCCG.TheCCG’ssecondRS485portcanbeused
tocreateanRS485busforcommunicationbetweentheinverters.ThisoptionisillustratedinFigure 5.

Installation Guidelines
ACwirespecifications:1.3to2.0mmdiameter/16-12AWGstrandedwire,600V,typeTHHN,MTW,or
THWN.
RS485wiringspecifications:
lCabletype:Min.3-wireshieldedtwistedpair(a4-wirecablemaybeused)
lWirecross-sectionarea:0.2-1mm²/24-18AWG(aCAT5cablemaybeused)
NOTE
If using a cable longer than 10 m/33 ft in areas where there is a risk of induced voltage surges by
lightning, it is recommend to use external surge protection devices. For details refer to External
Lightning Protection Connection on page 24. If grounded metal conduit are used for routing the
communication wires, there is no need for a lightning protection device.
lThemeterisconsidered“permanentlyconnectedequipment”andrequiresadisconnectmeans
(circuitbreaker,switch,ordisconnect)andovercurrentprotection(fuseorcircuitbreaker).
lThemeterdraws10-30mA,thereforetheratingofanyswitches,disconnects,fuses,and/orcircuit
breakersisdeterminedbythewiregauge,themainsvoltage,andthecurrentinterruptingrating
required.
lTheswitch,disconnect,orcircuitbreakermustbelocatednearthemeterandbeeasilyoperated.
lUsecircuitbreakersorfusesratedfor20Aorless.
lUsegroupedcircuitbreakerswhenmonitoringmorethanoneline.
lThecircuitbreakersorfusesmustprotectthemainsterminalslabeledL1,L2,andL3.Intherarecases
whereneutralhasovercurrentprotection,theovercurrentprotectiondevicemustinterruptboth
neutralandtheungroundedconductorssimultaneously.
lThecircuitprotection/disconnectsystemmustmeetallnationalandlocalelectricalcodes.
Installing and Connecting the Meter
Mountthemeteronawallorpoleusingthesuppliedbracket.
To mount the meter:
1. Installthebracketwiththesemi-circlesfacingdown,asshownbelow.Verifythatthebracketisfirmly
attachedtothemountingsurface.

blocks.
4. Openoneormoreconduitknockoutsaccordingtotheconduitsusedintheinstallation:Openthe
requiredknockout(s),eachwithtwosizes:¾''and1'',takingcarenottointerferewithanyofthe
internalcomponents.AUnibitdrillmaybeused.
CAUTION!
Use only knockouts located at the bottom, back and sides of the enclosure. Opening the top
knockouts may damage the protection rating of the enclosure.

SolarEdgerevenuegradeinvertershaveabuiltinRevenueGradeMeter(RGM).Fortroubleshooting
RGMs,refertohttp://www.solaredge.com/files/pdfs/built-in_rgm_troubleshooting.pdf.Thissection
describeshowtotroubleshootmeter-relatedinstallationandperformanceerrors.
Communication Status Screen Troubleshooting
Thecommunicationstatusscreenshoulddisplaythefollowing:
wwwwwwwwDev Prot ##
RS485-1<MTR><WN>< 1>
RS485-2<---><--><-->
Z i g B e e < - - - > < - - > < - - >
Device Type or Protocol are configured incorrectly
IfMTR(meter)isnotdisplayedasthedevicetype(DEV),orWN(WattNode)isnotdisplayedastheProt
(protocol),configurethemeterasfollows.:
1. SelectCommunicationèRS485-x ConfèDevice Typeè Revenue Meter.
2. SelectCommunication è RS485-x Conf è Protocol èWattNode.
3. CheckthattheDeviceIDunderCommunication è RS485-x Conf è Device IDissetto2.
4. SelectRevenue Meter è Meter Func. èExport+Import/Export/Import/Consumption.
Number of devices is not displayed
If<-->isdisplayedunderthe##columnintheCommunicationstatusscreen,themeterisnot
communicatingwiththeinverter.Checkthefollowing:
lThemeterconfigurationisasdescribedabove.
lTherearenolooseconnectionsattheinverterconnectorsandatthemeter,specificallytheRS485
wiring.
lThewiringbetweentheblack4-pinterminalblockonthemeterandtheRS485terminalblockonthe
communicationboardiscorrect,asshowninFigure 9.
lCheckforwaterdamageorsealingproblems:
oInspecttheentireconduitrunforpossiblepointsofwaterpenetration,andfixleaks.
oEnsurethatproperoutdoorratedcomponentsareused.
lUseaVoltmetertomeasurethevoltageonthemeter10-pinterminalblock.TheL1–L2linetoline
voltageshouldbe208-240Vac.

Flashing ON/OFF
oWhen the meter is connected at the grid connection point it indicates import
power measurement (CT directed towards the grid).
oWhen the meter is connected at the load connection point it indicates
consumption power measurement (CT directed towards the grid).
oWhen the meter is used for production it indicates production power
measurement (CT directed toward the inverter).

lAbnormaloperationindications:
oIfallLEDsareoff–themeterisnotoperating.Performalltroubleshootingstepsstartingwith
checkingthephysicalconnections.
oThefollowingtabledescribesadditionalLEDindicationsthatrequiretroubleshootingandrepair.
LED color Function Indication Troubleshooting
Red
ON for >3 sec. Internal error Contact SolarEdge Support.
Flashing ON/OFF Negative power for the
phase
If the meter is connected at the load
connection point or if the meter is used for
production metering, check for reversed CTs,
swapped CT wires, or CTs not matched with
the lines.
Flashing with green
LED
Voltage is too high for this
model
Disconnect power immediately!
Check the line voltages and the meter ratings.
Flashing with
yellow LED
The line voltage is out of
range (Vac ±20%).
Specifically, the voltage is
too low for the meter to
operate correctly and the
meter reboots repeatedly.
Verify that the voltage on the Vac screw
terminals is within the range of ±20% of the
nominal operating voltages printed in the white
rectangle on the front label.
Yellow
ON for >3sec.
Power line frequency is
below 45 Hz or above
70 Hz.
Check for the presence of high noise, for
example, the meter is too close to an unfiltered
variable frequency drive.
Flashing with red
LED
Voltage is too high for this
model
Disconnect power immediately!
Check the line voltages and the meter ratings.

GradeMeter(RGM),whichislocatedintheSafetySwitch.RS485wiringisdaisy-chainedbetweenthetwo
metersandtheinverter.
Connecting Two Meters
1. ConnecttheexternalmetertotheRGMasshowninFigure 17:
a. RoutetheexternalmeterwiresthroughoneoftheSafetySwitchconduits(itisrecommendedto
usetheDCsideconduits).
b. ConnecttheexternalmeterwirestogetherwiththeRGMwirestothesamescrewterminalsof
theRGMRS485terminalblock:
lRemovetheRGMwiresfromtheterminals(notethewirecolorandlocation).
lTwistthewirestogetherandinsertthemintotheterminal.
