5. DC power systems
ThissectionprovidesabriefoverviewofthecomponentsandfunctionswithinatypicalDCpowersystem.
Abasicpowersystemusuallyconsistsofrectifiersandbatteries,butcanalsoincludeothercomponents.
5.1. Guidelines for commissioning the DC system
ThefollowingsectioncontainsbasicguidelinesforcommissioningaDCpowersystem.Overallsystem
commissioningconsistsoffourparts:powersysteminspection,batteryinspection,commissioningthe
system,andtestingthesystem.Commissioningshouldonlybeconductedbyaqualifiedtechnician.For
moredetailedinformationrefertotherelevantsystemmanualforyourspecificsystem.
Performaninspectionofthepowersystemtoconfirmthatthemechanicalandelectricalrequirementsand
parametersarewithinspecification.Payspecialattentiontothebatterytoensureitisinstalledsafelyand
correctly,andthatthebatteryterminalsaretorquedtospecification.
1.
Makesureallpowertothesystemisoff.
Areallbatteriesdisconnected,rectifiermodulesareremoved,fusespulledandcircuitbreakers
turnedoff?
2. Makesurethebatterypolarityiscorrect.Useavoltmeterifnecessarytoconfirm.
3. Installonerectifier.
4.
TurnontheACtotherectifierandallowittostartup.
Verifythatthesystemstartsup,andthecontrollerturnson.Didtherectifierturnon?ACandDC
lightson?
Notice: With no load and batteries disconnected, the rectifier may have a fail alert. This
should go away when load is connected.
5. Confirmthebatterysettingsonthecontroller:capacity,chargelimit,thePeukertexponent.Ifthere
isnomeansofdisconnectingthebattery,thentherectifieroutputvoltageshouldbereducedby
usingthecontrollertomatchtherectifiervoltagetothebatteryvoltagetoavoidsparks.
6. Checkthatthebatterypolarityiscorrectandturnonthebreakers,fuseorcircuitbreakersforthe
batteries.
7. Followtheinitialbatterychargeprocedureasindicatedinthemanufacturer’sinstructions.
Thecontrollerandrectifiersareoperatingnormally.Theremayormaynotbeactivealarmsdependingon
systemconfiguration.
Performcommissioningteststoconfirmthatthesystemisoperatingproperly.Specificteststoperformwill
dependonthesystemconfigurationbutmayinclude:
• CorrectACinputvoltageandDCoutputvoltage
• Batterytest
• Relaytest
