Tus nqi tseem ceeb ntawm photovoltaic (PV) lub zog tsim hluav taws xob yog nyob rau hauv kev hloov lub hnub ci zog rau hauv hluav taws xob hluav taws xob thiab ua kom muaj txiaj ntsig zoo metering thiab kab sib txuas.
Lub DJZ1226 DC ntse lub zog ntsuas, ua tus sawv cev ntawm cov khoom sib xyaw shunt tsim, boasts ntau yam zoo hauv metering raug, ib puag ncig adaptability, installation, thiab txij nkawm vim nws sib sib zog nqus adaptability rau PV scenarios, ua rau nws yog ib qho zoo tagnrho xaiv rau DC metering ntawm PV fais fab tiam.
Cov ntsiab lus tseem ceeb rau Photovoltaic Scenarios
Lub tshuab hluav taws xob photovoltaic muaj qhov xwm txheej sib txawv- cov yam ntxwv tshwj xeeb:
Ua ntej, tag nrho cov txheej txheem tsim hluav taws xob yog nyob rau hauv DC hom, thiab qhov kev hloov pauv tam sim no cuam tshuam loj heev los ntawm irradiance thiab ambient kub, muab qhov xav tau siab heev ntawm cov lus teb dynamic thiab qhov tseeb ntawm cov khoom siv ntsuas.
Qhov thib ob, cov chaw nres tsheb fais fab feem ntau yog tsim nyob rau hauv qhov chaw qhib sab nraum zoov, ntsib kev nyuaj ib puag ncig xws li kub kub, nag, daus, thiab hluav taws xob cuam tshuam (tsim los ntawm kev ua haujlwm inverter).
Thib peb, lawv yuav tsum tau yoog raws qhov chaw compact installation thiab kev ua haujlwm yooj yim thiab kev saib xyuas ntawm cov chaw nres tsheb fais fab. Ib txwm DC lub zog ntsuas hluav taws xob feem ntau ua tsis tau raws li qhov yuav tsum tau ua ntawm photovoltaic scenarios vim muaj teeb meem xws li sab nraud shunts, tsis txaus los tiv thaiv - muaj peev xwm cuam tshuam, thiab cumbersome installation.
Scenario-raws li Qhov Zoo ntawm DJZ1226
High - ntsuas qhov tseeb
Nrog rau kev ntsuas qhov tseeb ntawm 0.5 lossis siab dua, DJZ1226 tuaj yeem ntes cov feeb tam sim no hloov pauv hauv photovoltaic modules - kom ruaj khov thiab raug ntsuas ntsuas hauv ob qho tib si qis - teeb, qis - tam sim no qhov xwm txheej thaum kaj ntug thiab tsaus ntuj, thiab nyob rau hauv lub hnub ci zog loj los ntawm kev tiv thaiv hnub ci. Nws txoj kev sib xyaw shunt tsim tshem tawm cov teeb meem tsis raug thiab teeb liab poob cuam tshuam nrog cov shunts sab nraud, ntxiv dag zog rau kev ntseeg siab ntawm cov ntaub ntawv ntsuas.
Ob Chav Lead Seal Protection, Tshem Tawm Metering Risks
PV fais fab nroj tsuag feem ntau yog nyob rau hauv ib puag ncig sab nraum zoov tsis muaj neeg saib, ua rau qhov xav tau tamper - pov thawj thiab tiv thaiv - kev ntsuas tub sab rau cov cuab yeej ntsuas qhov tshwj xeeb ceev.
Lub DJZ1226 khaws cov txiaj ntsig tseem ceeb ntawm nws cov qauv kev sib koom ua ke, ua tiav lub cev ua tiav rau lub ntsuas ntsuas (shunt + meter taub hau), kev tiv thaiv kev tiv thaiv tsis tau tso cai los yog hloov kho. Nyob rau tib lub sijhawm, nws muaj lub luag haujlwm hauv hluav taws xob, siv lub cim encrypted los sau cov khoom siv ua haujlwm hauv lub sijhawm. Nyob rau hauv qhov xwm txheej ntawm kev ua haujlwm tsis raug tso cai, lub kaw lus tam sim ntawd ua rau lub tswb nrov thiab khaws cov ntaub ntawv tampering, ua kom muaj kev lav phib xaub ntawm "kev tiv thaiv lub cev + kev saib xyuas hluav taws xob" kom ntseeg tau tias qhov tseeb thiab qhov cuam tshuam - pov thawj qhov xwm txheej ntawm cov ntaub ntawv ntsuas, ua tau raws li qhov yuav tsum tau ua ntawm daim phiaj - txuas metering.
Muaj zog ib puag ncig adaptability, tuav complex sab nraum zoov ua hauj lwm tej yam kev mob.
Tshwj xeeb ua kom zoo rau qhov chaw ua haujlwm sab nraum zoov ntawm cov chaw tsim hluav taws xob photovoltaic, DJZ1226 nta kev ua haujlwm kub ntau yam (-40℃txog +70} degree), yoog rau huab cua huab cua xws li siab - kub raug thiab qis- qhov kub thiab txias, kom ruaj khov ntsuas kev ua haujlwm. Nws cov khoom siv hluav taws xob tiv thaiv kev cuam tshuam tiv thaiv hluav taws xob hluav taws xob tsim los ntawm inverters, cov thawv sib txuas, thiab lwm yam khoom siv thaum lub sijhawm ua haujlwm, tiv thaiv kev ntsuas kev cuam tshuam los ntawm kev cuam tshuam.
Compact thiab yooj yim, txo hwj chim cog kev tsim kho thiab kev khiav hauj lwm nqi
Qhov chaw nruab rau inverters, cov thawv sib txuas, thiab lwm yam khoom siv hauv photovoltaic fais fab nroj tsuag yog compact. DJZ1226's integrated shunt tsim ho txo cov khoom loj. Nws cov qauv compact tuaj yeem muab tso ncaj qha rau hauv cov thawv sib txuas lossis cov khoom tswj, tshem tawm qhov xav tau rau qhov chaw ntxiv shunt thiab txuag ntawm cov nqi cog hluav taws xob.
Lub caij no, kev sib xyaw tsim ua kom yooj yim rau cov txheej txheem kev teeb tsa: tsis muaj kev sib cais ntawm shunts lossis txoj hlua txuas; installation tuaj yeem ua tiav yooj yim los ntawm kev txuas ncaj qha mus rau DC Circuit Court. Qhov no txo cov teeb meem kev tsim kho thiab cov nqi ua haujlwm, thiab tseem txo qis kev pheej hmoo ntawm kev ua haujlwm tsis zoo los ntawm kev xaim tsis raug.
Tsis tas li ntawd, cov khoom lag luam ua haujlwm ruaj khov nrog tus nqi tsis ua haujlwm tsawg, txo qis cov neeg ua haujlwm uas xav tau rau kev ua haujlwm tom qab thiab kev saib xyuas ntawm lub tshuab fais fab.
Kev hloov pauv hloov tau yooj yim, npog tag nrho PV daim ntawv thov scenarios
Lub DJZ1226 qhov ntsuas ntau tuaj yeem hloov kho mus rau PV fais fab nroj tsuag ntawm ntau qhov sib txawv: txawm tias nws qis - fais fab DC metering rau faib PV (chaw nyob thiab kev lag luam ru tsev) lossis siab - lub zog ntsuas xav tau ntawm lub thawv sib txuas thiab inverter sab ntawm centralized PV fais fab nroj tsuag, cov qauv kev xaiv muaj.
Lub caij no, tom qab cov khoom lag luam kev sib koom ua ke thiab kev txhim kho, nws txuas nrog lub photovoltaic xyuas qhov system, uploading metering cov ntaub ntawv hauv lub sijhawm. Qhov no pab cov thawj tswj fais fab nkag siab txog lub zog tsim hluav taws xob, txhim kho kev ua haujlwm thiab kev tswj xyuas cov tswv yim, thiab txhim kho kev ua haujlwm tag nrho ntawm lub tshuab hluav taws xob.
Xaus
Hauv kev lag luam photovoltaic fais fab kev lag luam, kev ntseeg siab thiab kev hloov pauv ntawm cov cuab yeej ntsuas ntsuas tau dhau los ua qhov tseem ceeb cuam tshuam.
Lub DJZ1226 DC ntse lub zog ntsuas, nrog nws cov shunt sib xyaw ua ke ua cov tub ntxhais, sib sib zog nqus qhov zoo xws li siab - ntsuas qhov tseeb, kev tiv thaiv dual kev nyab xeeb, muaj zog ib puag ncig adaptability, thiab yooj yim installation thiab txij nkawm. Nws raug phim rau cov kev xav tau ntawm kev tsim hluav taws xob photovoltaic, kom ntseeg tau qhov tseeb thiab ua raws li cov ntaub ntawv ntsuas ntsuas thaum txo tag nrho lub neej voj voog nqi ntawm lub chaw nres tsheb fais fab.
