A na u batla ho hokela liphanele tse peli tsa solar ho betri e le 'ngoe? U fihlile sebakeng se nepahetseng, hobane re tla u fa mehato ea ho e etsa ka nepo.
Joang ho hokahanya liphanele tse peli tsa letsatsi ho mafome a betere e le 'ngoe?
Ha o hokahanya tatellano ea liphanele tsa letsatsi, o hokahanya phanele e le 'ngoe ho e latelang. Ka ho kopanya lisebelisoa tsa letsatsi, potoloho ea likhoele e hahoa. Mohala o kopanyang setsi se seng se fosahetseng sa phanele ea letsatsi ho terminal e ntle ea phanele e latelang, joalo-joalo. Letotong ke e 'ngoe ea litsela tse bonolo tsa ho hokahanya lisebelisoa tsa hau tsa matla a letsatsi.
Mohato oa pele ke ho hokela betri ea hau ho selaoli sa ho tjhaja (MPPT kapa PWM). Ona ke mosebetsi oa pele o lokelang ho phethoa. U ipeha kotsing ea ho lematsa molaoli oa tefo haeba u hokela liphanele tsa letsatsi ho eona.
Ea hona joale eo molaoli oa hau oa ho tjhaja o e romelang libeteri ke eona e lekanyetsang hore na mohala o tenyetseha hakae. Mohlala, Renogy Rover 20A e fana ka li-amps tse 20 ho betri. Lithapo tse nang le matla a ho jara bonyane 20Amp lia hlokahala, joalo ka ts'ebeliso ea fuse ea 20Amp moleng. Mohala o le mong feela o lokelang ho kopanngoa ke o positive. Haeba u sebelisa terata ea koporo e tenyetsehang, u tla hloka terata ena ea AWG12. Kenya fuse haufi ka moo ho ka khonehang le likhokahano tsa betri.
Ebe u kopanya lisebelisoa tsa hau tsa letsatsi. Mothating ona, o tla hokahanya liphanele tsa hau tse peli tsa letsatsi.
Sena se ka etsoa ka tatellano kapa ka ho bapisa. Ha o kopanya liphanele tsa hau tse peli ka letoto, motlakase oa eketseha, ha o ntse o li kopanya ka tsela e tšoanang o eketsa hona joale. Ho hlokahala boholo ba terata bo bonyenyane ha ho etsoa wiring ka letoto ho feta ha wiring e bapile.
Mohala o tsoang setsing sa solar o tla ba khuts'oane haholo hore o ka fihla ho molaoli oa hau oa ho tjhaja. O ka e hokahanya le molaoli oa hau oa ho tjhaja o sebelisa mohala ona. Khokahano ea letoto le tla sebelisoa hangata. Ka lebaka leo, re tla tsoela pele ho etsa khokahano ea letoto. Beha tjhaja haufi le dibetri ka moo ho ka kgonehang. Beha molaoli oa hau oa tefiso haufi le liphanele tse peli tsa letsatsi ka hohle kamoo ho ka khonehang ho fokotsa tahlehelo ea mehala. Ho fokotsa tahlehelo, tlosa likhokahano leha e le life tse setseng tse hokelang liphanele tsa solar ho control controller.
Ebe, hokela meroalo efe kapa efe e menyenyane ea DC ho terminal ea motsamao oa litefiso. Haeba u batla ho sebelisa inverter, e hokele ho lihokelo tsa betri. Nahana ka setšoantšo se ka tlase e le mohlala.
Mohala o tsamaeang ka har'a lithapo o lekanya boholo ba oona. Haeba inverter ea hau e hula li-amps tse 100, thapo ea hau le likhokahano li tlameha ho lekana hantle.
Mokhoa oa ho sebelisa liphanele tse peli tsa letsatsi ka betri e le 'ngoe?
Ho etsa joalo, o tlameha ho hokahanya liphanele ka mokhoa o ts'oanang ho matlafatsa sistimi ea betri ea mafahla. Hokela li-negatives ho li-negatives le li-positives ho li-positives ho hokahanya lisebelisoa tse peli tsa letsatsi ka ho lekana. Liphanele ka bobeli li tlameha ho ba le motlakase o ts'oanang hantle ho fumana tlhahiso e phahameng. Mohlala, phanele ea letsatsi ea 115W SunPower e na le lintlha tse latelang:
Matla a phahameng a lekantsoeng ke 19.8 V.
Boemo bo phahameng bo teng = 5.8 A.
Matla a phahameng a lekanyelitsoeng = Li-Volt x Tse Teng = 19.8 x 5.8 = 114.8 W
Ha tse peli tsa likobo tsena li hokahane ka mokhoa o tšoanang, matla a maholo ka ho fetisisa ke 2 x 19.8 x 5.8 = 229.6 W.
Haeba liphanele tse peli li na le lintlha tse fapaneng tse hlahisoang, phanele e nang le matla a tlase ka ho fetesisa a nepahetseng e etsa qeto ea hore na motlakase o motle ka ho fetisisa bakeng sa sistimi. U tsielehile? A re bone hore na ho etsahala'ng ha motlakase oa rona oa letsatsi le kobo ea letsatsi li hokahanngoa.
18.0 V ke sebaka se loketseng sa motlakase.
Boemo bo phahameng ba hajoale ke 11.1 A.
19.8 volts ke matla a phahameng a lekantsoeng.
Boemo bo phahameng ba hajoale ke 5.8 A.
Ho li kopanya ka lihlahisoa tse tšoanang:
(304.2 W) = matla a phahameng a rekiloeng (18.0 x 11.1) Plus (18.0 x 5.8)
Ka lebaka leo, tlhahiso ea likobo tsa letsatsi e tla theoleloa ka 10% ho (18.0 x 5.8 = -RRB-104.4 W).
Mokhoa o motle oa ho hokahanya liphanele tse 2 tsa letsatsi ke ofe?
Ho na le litsela tse peli tse fapaneng tsa ho li hokahanya, 'me re tla buisana ka tsona ka bobeli mona.
Joaloka libeteri, liphanele tsa letsatsi li na le li-terminals tse peli: e 'ngoe e ntle le e mpe.
Ha terminal e ntle ea phanele e le 'ngoe e hokahane le terminal e mpe ea e' ngoe, ho hlahisoa khokahano ea letoto. Potoloho ea mohloli oa PV e thehiloe ha liphanele tse peli kapa ho feta tsa letsatsi li hokahantsoe ka mokhoa ona.
Ha liphanele tsa letsatsi li hokahane ka letoto, motlakase oa eketseha ha amperage e lula e sa fetohe. Ha liphanele tse peli tsa letsatsi tse nang le litekanyetso tsa 40 volts le 5 amps li hokahane ka letoto, motlakase oa letoto ke 80 volts mme amperage e sala ho 5 amps.
Matla a marang-rang a eketseha ka ho hokahanya liphanele ka letoto. Sena se bohlokoa hobane inverter ka har'a sistimi ea matla a letsatsi e tlameha ho sebetsa ka matla a boletsoeng hore e sebetse hantle.
Kahoo o hokela liphanele tsa hau tsa letsatsi ka letoto ho fihlela litlhoko tsa fensetere tse sebetsang tsa motlakase oa hau.
Ha liphanele tsa letsatsi li kentsoe ka ho bapa, terminal e ntle ea phanele e le 'ngoe e hokela ho terminal e ntle ea e' ngoe, 'me li-terminals tse mpe tsa liphanele ka bobeli lia hokela.
Lithapo tse ntle li hokahana le khokahanyo e ntle ka har'a lebokose la motsoako, athe lithapo tse mpe li hokela sehokelong se fosahetseng. Ha liphanele tse 'maloa li hokahantsoe ka mokhoa o ts'oanang, potoloho ea phallo ea PV e etsoa.
Ha liphanele tsa letsatsi li hokahane ka letoto, amperage ea phahama ha voltage e lula e sa fetohe. Ka lebaka leo, ho thaepa liphanele tse ts'oanang ka tsela e ts'oanang le pele ho boloka motlakase oa sistimi ho 40 volts empa ho eketsa amperage ho 10 amps.
O ka eketsa liphanele tse eketsehileng tsa letsatsi tse hlahisang matla ntle le ho feta lithibelo tsa motlakase oa inverter ka ho hokela ka ho bapisa. Li-inverters li boetse li lekantsoe ke amperage, e ka hlōloang ka ho hokela liphanele tsa letsatsi ka ho bapisa.
