SOLAR ELECTRIC MODULE ES-124 & ES-62TOwners Manual and Installation Guidecircuit. Reverseconnection will damagethe module and may resultin fire.CAUTIONSSolar electric modulesproduce DC electricitywhen exposed to light.The voltage from oneindividual module is notconsidered hazardous.However, if modules areconnected in series toincrease voltage, or inparallel to increase current,the shock hazard increases.When installing orworking aroundphotovoltaic modules,batteries and relatedelectrical equipment,observe industry standardsand practices as well asmanufacturer’s safetyrecommendations.WARNINGS- Cover the solar moduleswith an opaque materialbefore making your wiringconnections. This willprevent the modules fromproducing electricity whilemaking the connectionsand reduce the risk ofelectrical shock or sparks.- Use insulated tools andobserve safe electricalpractices at all times.- Make connections in awell-ventilated area freefrom flammable gasvapors and open flames.Observe proper polaritywhen connecting themodules into an electrical- Do not use any solarmodule without a blockingdiode to prevent reversecurrents from flowing intothe module from thebattery. A chargecontroller with a blockingdiode or “night-time”disconnect feature willwork well in this capacity.- Do not attempt toconcentrate sunlight on themodules for increasedoutput. Doing so maycause damage and willvoid the warranty.- Do not walk on themodules and avoiddropping any sharp objecton the face of the module.- Contact appropriateauthorities beforeinstalling solar electricmodules to determine ifpermits and inspectionsare required for yourparticular area.- Ground module frameand all metal structures forall systems of any voltage.AA4 3699-01

Themethods of installation,use and maintenance ofsolar modules are beyondthe control of UnitedSolar Ovonic. UnitedSolar Ovonic assumes noresponsibility andexpressly disclaimsliability for any loss,damage or expenseassociated with the use,installation or operation ofthe product. Any liabilityof United Solar Ovonic isstrictly limited to theLimited Warrantyattached hereto. UnitedSolar Ovonic reserves theright to make changes toproduct specifications orto the instruction manualwithout notice.Figure 2INSTALLATIONAA4 3699-01

MountingMounting holes on thealuminum frame of themodules are provided thatfit 7mm (¼ inch) diameterfasteners (see Figure 1 and2). Mount the ES-124module using eight (8)fasteners with lockwashers and nuts. Mountthe ES-62 module usingfour (4) fasteners with lockwashers and nuts.Clearance between themodule and the mountingsurface can be theminimum necessary toprevent wire chafing.When installing moduleson a building, use standoffor rack methods. Contactyour United Solar Ovonicdistributor for details.OrientationPick a location with themaximum exposure tosunlight. Avoid shadows,especially during themiddle of the day (i.e.“peak sun hours”, 09:30 to16:30). Orient the moduleso that the surface willreceive the maximum sunexposure over the year foryour particular site.Typically this is achievedby tilting the moduletoward the equator at anangle equal to the latitudeof the site. For optimumsummer performance,reduce the tilt angle by 15degrees below the latitudeangle. To increase winterperformance, increase thetilt angle 15 degrees abovethe latitude angle. The tiltangle should always begreater than 10º to ensureadequate rain watercleaning of the module.Wiring With Standard“Quick Connect”Terminals:The ES Series PV modulesare wired to your balanceof-systemcomponents orto other ES Series PVmodules using theexterior-rated, insulatedwires and “quick-connect”terminals. There is apositive wire with terminaland a negative wire withterminal. Modules can bewired in series up to 1000VDC max (TUV) & 600VDC per UL by pluggingthe male terminal into thefemale terminal, positiveto negative. The “quickconnect”wire terminalsare not designed to bedisconnected while themodule is producingpower. If the “quickconnect”terminals mustbe pulled apart while themodule is in the sun, thetechnician must cover thesolar module beforedisconnecting theterminals.Wiring With OptionalJunction Boxes:The ES Series modulescan also be ordered withstandard Junction Boxes.The junction box is locatedon the rear of eachmodule. To access thejunction box, loosen thefour (4) screws and lift offthe cover. The junctionbox is equipped with four(4) knockouts that willaccept either electricalconduit (13mm, ½ inchtrade size) or strain relieffittings. It is notrecommended to run wiresAA4 3699-01

You may use anycombination of knockoutsthat is the most convenientfor your installation.Proper use of a suitableblocking diode willprevent reverse currentflow into a module from abattery or from anothercharging source (ex. agenerator).properly sized fuse onsingle modules or stringsof modules wired inparallel with other stringsof modules (or individualmodules). See table forappropriate series fuserating.Bypass DiodesEvery solar moduleincludes a bypass diodeacross each cell, whichresults in reduced powerloss under partial shadowconditions. When two (2)or more modules areconnected in series, abypass diode can beinstalled in the modulejunction box using thesupplied jumpers,providing further shadowtolerance. For assistancecontact United SolarOvonic.Use a tool such as ascrewdriver to remove theknockout. The junctionbox cover should beplaced on the junctionbox before the knockoutis removed. Ascrewdriver should beplaced at the indicated(arrow) spot on thejunction box knockout.Install either a strain relieffitting or a conduit fitting.Follow the diagram inFigure 2 to make yourwiring connections.Reposition the cover onthe junction box andtighten the four (4) screws.Blocking Diodes andFusesAll systems that include abattery must have ablocking diode betweenthe battery and the solarmodule. Usually theblocking diode (or nighttimedisconnect circuit) isincluded with a chargecontroller (i.e. voltageregulator). Additionalseries blocking diodes canbe used within the array(one diode per parallelstring) to increase dailyarray output in locationswith severe shading overparts of the array duringpeak sun hours (09:30 to16:30).United Solar Ovonicrequires the use of aCharge RegulationThe use of a chargecontroller (i.e. voltageregulator) is recommendedin battery systems toprevent the solar modulefrom overcharging thebattery and to optimize thecharge rate for the battery.Follow the manufacturer’sinstructions for installationof the charge controller.High Voltage SystemsSolar modules are suitablefor use in high voltagesystems up to 1000 volts(TUV). Modules meetIEC 61646 requirements.Underwriters Laboratoryrates these same modulesfor use in high voltagesystems up to 600 VDC.Contact United SolarAA4 3699-01

Allowablewire size is 2.081 mm 2 –5.261 mm 2 (AWG #14-10). Wire insulation andsize should be chosen formaximum temperature andenvironment. Refer to theNational Electric Codesection 690.8 or otherrecognized standards.GroundingThe frame of each moduleshould be connected toearth ground. A selftapping screw and cupwasher are provided witheach module that can beused to attach a groundwire to the frame using thegrounding hole shown inFigure 1. Place a coppergrounding wire in betweenthe cup washer and screwhead. Module mountingfasteners can be used forgrounding purposes, inwhich case a star lockwasher must be used toensure a good electricalconnection to the moduleframe. Consult theNational Electric Code orother recognized standardsfor groundingrequirementswater. Do not use abrasivecleaners or solvents. Becareful when washing themodules, as thecombination of water andelectricity may present ashock hazard. Wearelectrical gloves anddisconnect the modulefrom the batteries.
