Lipalo-kholo tsa Solar Inverter Denit
Sengoloa se latelang se tla u thusa ho bala palo e phahameng ea boholo ba li-module ka ho khethela letoto la letoto la letoto la liliba tsa hau. 'Me ho kenella ho hoholo ho na le likarolo tse peli, lithaba tsa motlakase le tsa hona joale tsa morao-rao. Nakong ea li-mojaki ho etsa hore u nahane ka meeli e fapaneng ea tlhophiso, e lokelang ho nahanoa ha o sitisa polar-letsatsi la data le letsatsi la panel. 'Me nakong ea ho tsukutla, ho sebetsa ka hlooho ea mocheso ke ntho ea bohlokoa.
1. Mocheso oa Solar Panel oa Voc / ISC:
Voltage / Hona joale lipane tsa letsatsi li sebetsa ho mocheso oa selefouno, mocheso o phahamisang mocheso oa letsatsi le letsatsi, o tla hlahisa Lisebelisoa tsa motlakase / tsa hajoale li tla lula li le holimo maemong a batang haholo 'me ka mohlala, monko oa mocheso oa letsatsi o hlokahala ho sebetsa sena. Ka Mono le Crystalline ea Poneltalline e lula e le ntho e mpe ea% / OC OC Tlhahisoleseling ena e ka fumanoa holima WALL Panel Panel ea data ea Dalarrs tsa Dalarrs. Ka kopo sheba setšoantšo sa 2.
2. No. ea Solar Panels In Merillo:
Ha liphanele tse ntseng li le teng li na le li-pannels tse nang le lireschorenteng (tseo e leng tse ntle tse amanang le se fosahetseng sa phanele e latelang), Voltage ea sebaka ka 'ngoe e eketsoa hammoho ho fana ka voltage eohle ho fana ka voltage e felletseng. Ka hona, re hloka ho tseba hore na ke lipapatso tse kae tsa letsatsi le letsatsi u rerileng ho le terata ka lirerikeng.
Ha o na le tlhaiso-leseling eohle eo u e ikemiselitseng ho e kenya ka har'a voltage e latelang ea Warlage e latelang le lipalo tsa morao-rao tsa ho bona hore na ho tla ba le litlhokahalo tsa letsatsi.
Ho silafatsa lijo tsa voltage:
1. Voltage ea Max Panel = Voc * (1+ (Min.temp-25) * e koahetsoe ke mocheso (voc)
2. Palo ea Max ea Solar Panels = Max. Kenya Voltage ea Voltage / Max Panel
Side ea hajoale:
1. Min DAnell = ISC * (1+
2. Nomoro ea Max ea likhoele = max. ho kenya hape hajoale
3. Mohlala:
Cutiriba, e leng toropo ea Brazil, moreki o ikemiselitse ho kenya matla a mabeli a poleloana ea poleho, VMPT 1000v.
Ka ho khetheha le databae:
Solar Panel Deallet:
A) Ho sebelisa chelete
Ka mocheso o tlase (sebaka sa bolulo, mona-vs), majaba a pohi a bulehileng
1) Palo ea li-voltage tse bulehileng tsa Pono ea Pono ea Pono ea Pono ea Polelo ho -3 ℃:
Voc (-3 ℃) = 45.5 * (1 + (- 3-25) * (- - 333%)) = 49.7 Volt
2) Palo ea palo ea palo e phahameng ea li-module tse kholo ka lehlakoreng le leng le le leng:
N = Max account voltage (1000 v) /49.7 Volt = 20.12 (e lula e potoloha)
Palo ea li-panels tsa Solar PV ka khoele e 'ngoe le e' ngoe li sa lokela ho feta, mocheso o moholo oa 35 ℃), mona, mona)
3) Palo ea palo ea voltage Voltage VMPE ho 35 ℃:
VMPP (35 ℃) = 45.5 * (1-25) * (- 0,33%)) = 44 Volt
4) Palo ea palo e fokolang ea li-module m ka mohlokong ka mong:
M = Min mcp voltage (160 v) / 44 volt = 3.64 (e lula e le holimo)
Palo ea li-panels tsa Solar PV ka khoele e 'ngoe le e' ngoe e lokela ho ba bonyane li-module tse 4.
B) Side ea hajoale
Potoloho e Khutsong ea morao-rao ea pele ke sa e-ba le mehala ea PV
1) Palo ea palo ea boemo ba hajoale ho 35 ℃:
ISC (35 ℃) = (1+ (10 * (TCSC / 100)) = 9.22 * (136%) *) = 9.16 a
2) Palo ea palo ea palo e phahameng ea likhoele:
P = ho kenya ka bongata hajoale (12.5a) /9.16 A = 1.36 likhoele (kamehla ho pota)
Mesebetsi ea PV ha ea lokela ho feta khoele e le 'ngoe.
TLHOKOMELISO:
Mohato ona ha o hlokehe bakeng sa severter mppt e nang le thapo e le 'ngoe feela.
C) Phetho:
1. Lebili la PV (PV ea PV) e na lekhoele e le 'ngoe, e amanang le karolo e meraro ea 5kw.
2. Ka khoele ka 'ngoe e hokahaneng ea letsatsi e hokahane e lokela ho banakong ea likhabu tsa 4-20.
TLHOKOMELISO:
Ho tloha ka ho fetisisa MPP ea MimpT ea MimpT e meraro e ka bang 630V (katleho e ntle ea MPP e le 'ngoe e haufi le 360 ea ho sebetsa ka ho fetisisa ke eona e phahameng ka nako ena. Kahoo ho khothalletsoa ho bala palo ea li-module tsa Solar tsa letsatsi ho ea ka volt ea MPT ea MPT:
N = ho feta MPPT ea MPPT ea MPPT (-3 ° C) = 756v / 49.7v = 1511
Senyi se le seng sa kristale sa MPPT VOC = Best MPT Voltage x 1.3 = 630 × 1.2 = 756V
Polycrystal Panel MPPT Voc = Best MPT Voltage x 1.3 = 630 × 1.3 = 819V
Kahoo bakeng sa Renac 3 mekhahlelo ea li-s3-5k-DT tse khothalletsoang tsa letsatsi ke li-module tse 16, 'me u hloka feela ho hokahanya thapo e le' ngoe 16x330w = 5280w = 5280w = 5280w = 5280w = 5280w = 5280w = 5280w = 5280w = 5280w = 5280w.
4. Qeto
Ho kenya ka hare ho sephara ho sa fane ka mocheso oa sele le mocheso. Ts'ebetso e ntle ka ho fetisisa e ipapisitse le voltage ea MPT ea MPTT.
