I-solar engaphakathi i-Inverter

I-solar engaphakathi i-Inverter

Inqaku elilandelayo liza kukunceda ukubala ubuninzi beemodyuli zemodyuli kwi-Prim String xa uyila inkqubo yakho ye-PV. Kwaye i-inverter yomzobo iquka iinxalenye ezimbini, i-voltage, kunye nokusetyenziswa kwangoku. Ngexesha lokulinganisa i-inverter kuya kufuneka uthathele ingqalelo imida yoqwalaselo eyahlukileyo, ekufuneka ithathelwe ingqalelo xa isebenzisa i-Inverter yamandla eNqaku (idatha evela kumaphepha edatha ye-Inverter kunye neSolar Pop). Kwaye ngexesha lokulinganisa, iqondo lokuhlaselwa kweqondo lokusebenza liyinto ebalulekileyo.

I-1. I-Solar Panel I-Couneral Ally yeVoC / SC:

I-voltage / yangoku esebenza i-solar isebenza kuxhomekeke kubushushu beseli, iqondo lobushushu liphezulu iphantsi kwe-voltage / i-solar yephaneli iya kuvelisa kwaye ivelise i-solar versa. I-voltage / yangoku yenkqubo iya kuhlala iphezulu kwiimeko ezibandayo kwaye umzekelo, amaqondo obushushu elanga elinobushushu olandelelana kwe-VOC kufuneka asebenze oku. Nge-Mono kunye ne-Poly Crystallie Ponels Ihlala ingumntu ombi / we-OC, onje-30.33% / oC kwiLanga 72p-35F. Olu lwazi lunokufumaneka kwi-solar ye-solar yedatha yedatha. Nceda ujonge umfanekiso 2.

I-2. Hayi. Iipaneli zelanga kwintambo ye-Pricting:

Xa iipaneli zelanga zitshixiwe kwimitya yochungamileyo (leyo le phalane iqhagamshelwe kwipaneli elandelayo), i-voltage yephaneli nganye idityanisiwe ukuze inike i-voltage iyonke. Ke ngoko kufuneka sazi ukuba zingaphi iipaneli zeSolar ozimisele ukuwa engcelele.

Xa unalo lonke ulwazi olileleyo lokungenisa kwi-voltage ye-solar ye-solar yelanga kunye nokubala ngokusisimbano ukuze ubone ukuba uyilo lwephaneli luya kuhambelana neemfuno zakho.

I-voltage yomzobo:

I-1. I-volnel yepaneli ye-max = i-voc * (1+ (Min.tem-25) * I-HOCE COERTE
I-2. Inombolo ye-max ye-solar yelanga = max. I-infting voltage / i-volnel yepaneli yepaneli

Umdlalo wangoku:

I-1. I-Pernel ye-Mins yangoku = ISC * (1+
I-2. Inombolo yentambo = max. Igalelo langoku / i-phanel yangoku

3. Umzekelo:

I-curitiba, isixeko saseBrazil, umthengi sikulungele ukufaka i-Prenac Prem Runter 5KW isiGaba seSigaba seSolar yi-38.8v, i-vortage ye-MPPT i-37.8v, i-VMPP ye-MPPP ye-37.8v, kwaye elona gozulo liphezulu linokukhulisa I-1000V.

I-Inverter kunye neDatasheet:

I-Solar Paneheet:

A) i-voltage yomzobo

Kwiqondo eliphantsi leqondo elingaphantsi (Indawo exhomekeke kuyo, apha -3 ℃), i-Voltage evulekileyo ye-OC yeemodyuli kumtya ngamnye we-inverter (1000 v):

1) Ukubalwa kwe-voltage yesiphaluka evulekileyo kwi-3 ℃:

I-VOC (-3 ℃) = 45.5 * (1 + (- 3-25) * (- 0.3.7) volt

2) Ukubalwa kwenani eliphezulu leemodyuli kwintambo nganye:

N = i-max voltage (i-1000 v) /4.7 Volt = 20.12 (ihlala ijikeleza)

Inani leephaneli ze-PV nganye akufuneki zidlule kwimodyuli ezingama-20 ngaphandle kweyona ndawo iphakamileyo (yendawo exhomekeke kwi-MPP yomtya ngamnye kufuneka ibe ngaphakathi kwe-MPP yamaNqaku kweSolar (160v-950V):

3) Ukubalwa kweyona voltage ye-voltage yamandla e-vmpp kwi-35 ℃:

I-VMPP (35 ℃) = 45.5 * (35+ (35-25) * (- 0.33%) = 44 volt

4) Ukubalwa kwenani elincinci leemodyuli m kwintambo nganye:

M = Min MPP World (160 v) / 44 Volt = 3.64 (ihlala ijikeleza)

Inani leephaneli ze-PV ze-hlv kumtya ngamnye kufuneka ubuncinci ziimodyuli ezi-4.

B) Ukusetyenziswa okwangoku

Isekethe emfutshane yangoku i-SC ye-PV ART akufuneki idlule kwigalelo elivumelekileyo langoku kwi-inverter yamandla elanga:

1) Ukubalwa kweyona ndawo iphambili kwi-35 ℃:

I-ISC (35 ℃) = ((1+ (10 * (i-TCSC / 100))) * I-ISC) = 9.22 * (35.16%) = 9.16 a

2) Ukubalwa kwe-P elona nani liphezulu lemitya:

P = igalelo eliphezulu langoku (12.5a) / 9.16 a = 1.36 ntambo (uhlala ujikeleza)

I-PV ARHARY akufuneki idlule umtya omnye.

I-tesk:

Eli nyathelo alifuneki kwi-Inverter Sppt ngomtya omnye kuphela.

C) Ukuqukumbela:

1. I-PV Generator (PV ART) iqulatheumtya omnye, eqhagamshelwe kwi-5kw engaphakathi kwi-5KWw ingaphakathi.

2. Kumtya ngamnye iiphaneli zelanga ezixhunyiwe kufuneka zibekhonangaphakathi kwe-4 ukuya kwimodyuli.

I-tesk:

Kuba i-MPTP ye-MPTP elungileyo ye-INVERT yesiGaba esiSithathu ijikeleze i-630V yombane we-Inverter yenqanaba elinye ijikeleze i-360v), ukusebenza kakuhle kwe-inverter ngololo xesha. Ke kuyacetyiswa ukubala inani leemodyuli zelanga ngokweyona volthi ilungileyo ye-MPPP:

N = I-MPTPT ye-MPTP / VOC (-3 ° C) = 756v / 49.7v = 15.21

Ipaneli eyodwa ye-crystal ye-mptpt voc = i-MPPP ye-MPPP ye-X 1.2 = 630 × 1.2 = 756v

I-Polycrystal Panel ye-MPTP ye-MPTPT VOC = I-MPPP ye-MPPP ye-X 1.2 = 630 × 1.3 = 819v

Ke ye-renac yenqanaba lesigaba se-Interter R3-5k-DT-DT I-SOREPORY I-SORORS i-16 yeemodyuli, kwaye kufuneka nje iqhagamshelwe umtya omnye 16x330w = 5280w.

4. Ukuqukumbela

Igalelo leverter alukho kwiiphaneli zesolar kuxhomekeke kubushushu baselfowuni kunye nobushushu bokusebenza. Eyona ntsebenzo ilungileyo isekwe kwi-MPPP ye-MPPP efanelekileyo ye-inverter.
