Kev ua haujlwm ntawm hnub ci inverters yog hais txog kev lag luam loj hlob ntawm hnub ci inverters (photoelectric inverters) vim qhov kev thov rau lub zog tauj dua tshiab. Thiab cov inverters no xav tau kev ua haujlwm siab thiab kev ntseeg siab. Cov hluav taws xob hluav taws xob siv hauv cov tshuab hluav taws xob no tau tshuaj xyuas thiab cov kev xaiv zoo tshaj plaws rau cov keyboards thiab rectifiers raug pom zoo. Cov qauv dav dav ntawm photovoltaic inverter yog qhia hauv daim duab 1. Muaj peb qhov sib txawv inverters xaiv los ntawm. Lub hnub ci ci rau hnub ci modules txuas nrog hauv cov koob, thiab txhua lub module muaj cov hnub ci cell txuas nrog hauv series. Qhov hluav taws xob ncaj qha tam sim no (DC) hluav taws xob tsim los ntawm hnub ci modules yog nyob ntawm qhov kev txiav txim ntawm ntau pua volts, thiab cov txiaj ntsig tshwj xeeb nyob ntawm qhov teeb pom kev zoo ntawm lub module array, qhov kub ntawm lub roj teeb, thiab tus naj npawb ntawm cov modules txuas nrog series.
Lub luag haujlwm tseem ceeb ntawm hom inverter no yog hloov cov input DC voltage rau tus nqi ruaj khov. Qhov no muaj nuj nqi yog siv los ntawm ib tug boost converter thiab yuav tsum tau ib tug boost hloov thiab ib tug boost diode. Nyob rau hauv thawj configuration, lub boost theem yog ua raws li ib tug cais tag nrho -bridge converter. Lub luag haujlwm ntawm tag nrho -bridge transformer yog muab kev sib cais. Qhov thib ob puv -bridge converter ntawm qhov tso zis yog siv los hloov qhov ncaj qha - tam sim no DC ntawm thawj - theem puv -bridge converter rau hauv qhov hluav taws xob hloov pauv (AC) voltage. Nws cov zis yog lim ua ntej txuas nrog AC daim phiaj network los ntawm ob qho ntxiv -hu rau relay hloov, nrog rau lub hom phiaj ntawm kev muab kev sib cais kom muaj kev nyab xeeb yog tias muaj teeb meem thiab kev cais tawm ntawm daim phiaj hluav taws xob hmo ntuj. Tus qauv thib ob yog qhov tsis yog{13}} cov txheej txheem cais. Lub AC alternating voltage yog ncaj qha generated los ntawm DC voltage tso zis los ntawm lub boost theem. Tus qauv thib peb siv lub thev naus laus zis thev naus laus zis ntawm lub zog hloov hluav taws xob thiab lub zog diodes los ua ke cov haujlwm ntawm kev txhawb nqa thiab AC AC tiam qhov chaw nyob rau hauv ib qho kev mob siab rau topology. Txawm hais tias kev hloov dua siab tshiab ntawm lub hnub ci vaj huam sib luag yog tsawg heev, lub inverter efficiency yog ntau li ntau tau Ze rau 100% yog ib qho tseem ceeb heev. Nyob rau hauv lub teb chaws Yelemees, 3kW series module tau nruab rau sab qab teb-fab lub ru tsev xav kom tsim tau 2550 kWh ib xyoos twg. Yog hais tias lub inverter efficiency yog nce los ntawm 95% mus rau 96%, ib qho ntxiv 25kWh tuaj yeem tsim txhua xyoo. Tus nqi tsim tawm no 25kWh nrog ib qho ntxiv hnub ci module yog piv rau kev ntxiv ib qho inverter. Txij li thaum nce qhov kev ua tau zoo ntawm 95% mus rau 96% yuav tsis ua ob npaug ntawm tus nqi ntawm lub inverter, kev nqis peev hauv lub inverter muaj txiaj ntsig yog qhov kev xaiv tsis tau. Rau cov qauv tsim tawm tshiab, tus nqi ntau tshaj - txoj hauv kev zoo los txhim kho inverter efficiency yog qhov tseem ceeb tsim qauv. Raws li kev ntseeg tau thiab tus nqi ntawm lub inverter, muaj ob txoj hauv kev tsim qauv. Kev ua tau zoo dua tuaj yeem txo qhov kub ntawm qhov hloov pauv ntawm lub voj voog thauj khoom, yog li ua kom muaj kev ntseeg siab, yog li cov lus qhia no muaj feem xyuam nrog. Kev siv cov modules kuj txhim kho kev ntseeg tau.
