Raws li hnub ci hluav taws xob cia cov tshuab ua nrov ntau, feem ntau cov neeg tau paub txog cov tsis muaj zog ntawm lub zog cia inverters. Txawm li cas los xij, tseem muaj qee qhov tsis tsim nyog nkag siab txog qhov tob. Niaj hnub no, Kuv tau xaiv plaub yam uas feem ntau tau saib xyuas thaum xaiv lub zog siv Inverters tab sis yog qhov tseem ceeb rau kev xaiv cov khoom lag luam zoo. Kuv cia siab tias tom qab nyeem kab lus no, txhua tus yuav muaj peev xwm xaiv qhov uas tsim nyog dua thaum ntsib ntau yam khoom siv hluav taws xob.
01 roj teeb voltage ntau
Tam sim no, lub zog cia invererers ntawm kev ua lag luam tau muab faib ua ob pawg raws li ntawm cov roj teeb hluav taws xob. Ib hom yog tsim rau 48v ntsuas roj teeb roj teeb, nrog lub roj teeb roj teeb ntau feem ntau ntawm 40-60V, hu ua tsawg-voltage roj teeb khaws cia inverters. Lwm hom yog tsim rau high-voltage roj teeb, nrog rau cov roj teeb volterage ntau, feem ntau nrog roj teeb ntawm 200v thiab saum toj no.
Cov lus pom zoo: thaum kev yuav khoom siv hluav taws xob cia inverters, cov neeg siv yuav tsum tau them nyiaj tshwjxeeb rau cov inverter tuaj yeem haum, kom ntseeg tau tias yog qhov hluav taws xob tiag tiag ntawm cov roj teeb.
02 Lub Photovoltaic Lub Zog
Qhov siab tshaj plaws photovoltaic cov hwj huam tawm tswv yim qhia txog lub zog siab tshaj plaws lub photovoltaic ib feem ntawm inverter tuaj yeem lees txais. Txawm li cas los xij, lub hwj chim no tsis tas yog lub zog tshaj plaws lub inverter tuaj yeem lis. Piv txwv li, rau 10kW inverter, yog tias cov photveroltaic lub zog tawm yog 20kW, qhov siab tshaj plaws ua rau muaj kev tawm ntawm Inverter tseem tsuas yog 10kW. Yog hais tias ib tug 20kw photovoltaic array tau txuas, muaj feem ntau yog lub zog poob ntawm 10kW.
Kev tsom xam: coj tus piv txwv ntawm lub zog zoo khaws cia inverter, nws tuaj yeem khaws 50% ntawm lub photovoltaic thaum tsim tawm 100% AC. Rau 10kw inverter, qhov no txhais tau tias nws tuaj yeem tso 10KW AC thaum khaws cia 5kW ntawm photovoltaic lub zog hauv lub roj teeb. Txawm li cas los xij, txuas rau 20kW array yuav tseem pov tseg 5kW ntawm photovoltaic lub zog. Thaum xaiv ib qho inverter, xav txog tsis tsuas yog photovoltaic tawm lub zog tab sis kuj yog lub zog tiag tiag lub inverter tuaj yeem tswj tau ib txhij.
03 AC overload muaj peev xwm
Rau kev siv hluav taws xob cia invererers, AC ib sab feem ntau muaj cov kab sib tshooj tawm thiab tawm ntawm cov khoom tso tawm.
Kev Ntsuam Xyuas: Daim phiaj-khi cov khoom siv feem ntau tsis muaj kev sib txuas lus vim tias thaum muaj kev sib txuas lus, thiab cov inverter tsis tas yuav ua rau lub nra hnyav.
Cov khoom tawm ntawm cov kab sib xyaw tawm, ntawm qhov tod tes, feem ntau yuav tsum muaj cov peev txheej luv luv vim tias tsis muaj kev txhawb nqa thaum ua haujlwm. Piv txwv li, ib lub zog 8kW lub zog cia hluav taws xob tuaj yeem muaj ib daim phiaj tso tawm hluav taws xob ntawm 8kva, nrog rau qhov pom kev zoo tshaj plaws ntawm 16kva txog li 10 vib nas this. Lub sijhawm 10-thib ob no feem ntau yog txaus los tuav cov kev nce tam sim no thaum lub sijhawm pib siv hluav taws xob feem ntau.
04 kev sib txuas lus
Kev sib txuas lus sib txuas lus ntawm lub zog cia cov inverters feem ntau suav nrog:
4.1 Kev sib txuas lus nrog roj teeb: Kev sib txuas lus nrog roj teeb lithium feem ntau yog kev sib txuas lus, tab sis kev cai ntawm cov chaw tsim khoom sib txawv yuav sib txawv. Thaum kev yuav khoom siv roj inverters thiab roj teeb, nws yog ib qho tseem ceeb kom paub meej tias yuav tsis txhob muaj teeb meem tom qab.
4.2 Kev sib txuas lus nrog kev saib xyuas platform
4.3 Communication with Energy Management Systems (EMS): Communication between energy storage systems and EMS typically uses wired RS485 with standard Modbus communication. Tej zaum yuav muaj qhov sib txawv ntawm cov qauv tsim qauv, yog li yog tias muaj kev sib txuas lus nrog cov modbus raws cov qauv qhia ua ntej xaiv cov inverter.
Lub ntsiab
Lub zog cia cov tsis muaj zog yog ua rau muaj kev sib cav, thiab cov cav taw tom qab txhua qhov ntsuas tau cuam tshuam ntawm kev siv hluav taws xob cia khoom siv hluav taws xob.
