Abanye abantu bathi ixabiso le-photovoltaic inverter liphezulu kakhulu kunemodyuli, ukuba lingasebenzisi ngokupheleleyo amandla aphezulu, liya kubangela inkcitho yemithombo.Ngoko ke, ucinga ukuba ukuveliswa kwamandla ombane wesityalo kunokunyuswa ngokongeza iimodyuli ze-photovoltaic ezisekelwe kumandla aphezulu wokufaka inverter.Kodwa ngaba kunjalo ngokwenene?

Enyanisweni, asiyiyo le nto yathethwa ngumhlobo.I-Photovoltaic inverter kunye ne-photovoltaic module ratio ngokwenene iyingxenye yesayensi.Ukuhlanganiswa okufanelekileyo kuphela, ukufakwa kwenzululwazi kunokunika ngokwenene umdlalo ogcweleyo ekusebenzeni kwenxalenye nganye, ukuphumeza ukuveliswa kwamandla okusebenza kakuhle.Iimeko ezininzi kufuneka ziqwalaselwe phakathi kwe-photovoltaic inverter kunye nemodyuli ye-photovoltaic, njengokukhanya kokuphakama kokukhanya, indlela yokufakela, indawo yesayithi, imodyuli kunye ne-inverter ngokwayo njalo njalo.

Okokuqala, ukunyusa ukukhanya

Imimandla yemithombo yamandla elanga inokwahlulwa ibe ziiklasi ezintlanu, eyokuqala, yesibini neyesithathu iintlobo zeendawo ezinobutyebi bokukhanya zizityebi, uninzi lwelizwe lethu lungezi klasi, ngoko ke ifaneleke kakhulu ukufakela inkqubo yokuvelisa amandla e-photovoltaic.Nangona kunjalo, ubukhulu bemitha buhluka kakhulu kwimimandla eyahlukeneyo.Ngokuqhelekileyo, okukhona i-Angle yobude belanga, inamandla emitha yelanga, kwaye okukhona iphakamile, kokukhona yomelela imitha yelanga.Kwiindawo ezinobungakanani obuphezulu bemitha yelanga, impembelelo yokutshatyalaliswa kobushushu be-photovoltaic inverter nayo ihlwempuzekileyo, ngoko ke i-inverter kufuneka ikhutshwe ukuze iqhube, kwaye umlinganiselo wamacandelo uya kuba ngaphantsi.

Emibini, imiba yofakelo

Umlinganiselo we-inverter kunye necandelo lesikhululo samandla se-photovoltaic siyahluka kunye nendawo yokufakela kunye nendlela.

Ukusebenza kwenkqubo yecala le-1.Dc

Ngenxa yokuba umgama phakathi kwe-inverter kunye nemodyuli mfutshane kakhulu, intambo ye-DC imfutshane kakhulu, kwaye ilahleko incinci, ukusebenza kakuhle kwenkqubo yecala le-DC inokufikelela kuma-98%.Ngenxa yokuba intambo ye-DC inde, amandla avela kwimitha yelanga ukuya kwimodyuli ye-photovoltaic kufuneka adlule kwintambo ye-DC, ibhokisi ye-confluence, i-DC yekhabhathi yokusabalalisa kunye nezinye izixhobo, kunye nokusebenza kakuhle kwenkqubo yecala le-DC ngokubanzi kungaphantsi kwe-90% .

2. Ukutshintsha kwamandla ombane kwigridi yamandla

Amandla aphezulu okukhutshwa kwe-inverter ayitshintshi.Ukuba igridi edibeneyo yegridi iyancipha, ngoko i-inverter ayikwazi ukufikelela kwisiphumo sayo esilinganisiweyo.Masithi samkela i-inverter ye-33kW, ubuninzi bemveliso yangoku yi-48A kunye ne-voltage ephumayo elinganisiweyo yi-400V.Ngokutsho kwefomula yokubala amandla esigaba sesithathu, amandla okuphuma yi-1.732 * 48 * 400 = 33kW.Ukuba i-voltage yegridi yehla ukuya kwi-360, amandla aphumayo aya kuba yi-1.732 * 48 * 360 = 30kW, engenakufikelela kumandla alinganisiweyo.Ukwenza ukuveliswa kwamandla kungasebenzi kakuhle.

3.inverter ukutshatyalaliswa kobushushu

Ubushushu be-inverter buchaphazela amandla okukhutshwa kwe-inverter.Ukuba i-inverter ye-heat dissipation effect ihlwempuzekile, ngoko amandla aphumayo aya kuncipha.Ngoko ke, i-inverter kufuneka ifakwe ngaphandle kwelanga elithe ngqo, iimeko zomoya ezilungileyo.Ukuba indawo yokufakela ayilungile ngokwaneleyo, ngoko ke ukuchithwa okufanelekileyo kufuneka kuthathelwe ingqalelo ukukhusela i-inverter ekufudumeni.

Ntathu.Amalungu ngokwawo

Iimodyuli ze-Photovoltaic ngokubanzi zinobomi benkonzo ye-25-30 iminyaka.Ukuze kuqinisekiswe ukuba imodyuli isenako ukugcina ukusebenza kakuhle ngaphezu kwe-80% emva kobomi benkonzo eqhelekileyo, i-factory yemodyuli eqhelekileyo inomda owaneleyo we-0-5% kwimveliso.Ukongezelela, ngokuqhelekileyo sikholelwa ukuba iimeko zokusebenza eziqhelekileyo zemodyuli ziyi-25 °, kwaye ukushisa kwemodyuli ye-photovoltaic kuyancipha, amandla emodyuli aya kwanda.

Isine, i-inverter eyeyakho imiba

I-1.inverter ukusebenza kakuhle kunye nobomi

Ukuba senza i-inverter isebenze ngamandla aphezulu ixesha elide, ubomi be-inverter buya kuncitshiswa.Uphando lubonisa ukuba ubomi be-inverter esebenza kwi-80% ~ 100% amandla ancitshiswe ngama-20% kunoko kwi-40% ~ 60% ixesha elide.Ngenxa yokuba inkqubo iya kutshisa kakhulu xa isebenza kumandla aphezulu ixesha elide, ubushushu bokusebenza kwenkqubo buphezulu kakhulu, obuchaphazela ubomi benkonzo.

2,olona luhlu lusebenzayo lwamandla ombane we-inverter

I-voltage esebenzayo ye-inverter kwi-voltage elinganisiweyo, elona xabiso liphezulu, i-inverter yesigaba esisodwa se-220V, i-inverter igalelo elilinganiselwe i-voltage 360V, i-inverter ye-380V yesigaba sesithathu, i-voltage efakwe kwi-650V.Njenge-3 kw photovoltaic inverter, enegunya le-260W, i-voltage yokusebenza ye-30.5V 12 iibhloko iyona ifanelekileyo;Kwaye i-30 kW inverter, ukuhanjiswa kwamandla kumacandelo angama-260W amaqhekeza angama-126, kwaye emva koko indlela nganye i-21 imicu iyona ifanelekileyo.

3. Umthamo ogqithisiweyo we-inverter

Ii-inverters ezilungileyo ngokubanzi zinomthamo omninzi, kwaye amanye amashishini awanaso umthamo ogqithisileyo.I-inverter ene-overload umthamo onamandla inokulayisha ngaphezulu kwamandla aphezulu okuvelisa i-1.1 ~ 1.2 amaxesha, inokuxhotyiswa ngama-20% amacandelo ngaphezu kwe-inverter ngaphandle komthamo ogqithisiweyo.

I-inverter ye-Photovoltaic kunye nemodyuli ayikho i-random kwaye, ukuba ibe yi-collocation enengqiqo, ukwenzela ukuphepha ilahleko.Xa ufaka izikhululo zamandla e-photovoltaic, kufuneka siqwalasele izinto ezahlukeneyo ngokubanzi, kwaye ukhethe amashishini e-photovoltaic aneziqinisekiso ezibalaseleyo zofakelo.
