(1) Musanayambe kukonza, choyamba tsegulani kugwirizana kwa magetsi pakati pa inverter ndi gridi, ndiyeno kulumikiza magetsi ku mbali ya DC. Ndikofunikira kudikirira kwa mphindi zosachepera 5 kapena kupitilira apo kuti ma capacitor apamwamba kwambiri ndi zida zina mkati mwa inverter zitulutsidwe kwathunthu musanagwire ntchito yokonza.

(2) Pokonza ntchito yokonza, choyamba, kuyang'ana PV inverter kwa kuwonongeka kulikonse kapena zochitika zina zoopsa ndi kulabadira odana ndi malo amodzi mu ndondomeko yeniyeni ntchito, ndi bwino kuvala odana malo amodzi dzanja mphete. Samalani zizindikiro zochenjeza pa inverter ndikuyang'ana pamwamba pa inverter pambuyo pozizira. Pa nthawi yomweyo kupewa kukhudzana zosafunika pakati thupi ndi dera matabwa.

(3) Pambuyo pokonza, onetsetsani kuti zolakwika zilizonse zomwe zimakhudza chitetezo cha inverter zachotsedwa musanayambe kuyatsa pa inverter.

Chifukwa cha zomwe zachitika:

(1) Palibe voteji kumbali ya AC yotulutsa inverter, kulephera kwamphamvu kwamagetsi.

(2) Malo opangira ma inverter AC sanalumikizidwe bwino kapena mzere wa terminal ndi womasuka.

Yankho:

(1) Chonde gwiritsani ntchito ma multimeter kuti muyeze voteji ya AC ya inverter, nthawi zonse malo opangira magetsi ayenera kukhala ndi gawo 380V;

(2) Chonde yesani motsatizana ngati ma terminals ali otayirira, ngati chowotcha cha AC chatsekedwa kapena ayi, komanso ngati switch yoteteza kutulutsa kwapadziko lapansi yatha kapena ayi.

Chifukwa cha zomwe zachitika: 

Magetsi ndi mafupipafupi a gridi ya AC zachoka munjira yoyenera.

Yankho:

(1) Chonde yang'anani mphamvu zowunikira komanso mbiri yanthawi zonse kuti muwone ngati pali zinthu zina zomwe zili pamtundu wa chitetezo.

(2) Chonde yezani voteji ya gridi ya AC ndi multimeter, ngati ili yachilendo, ndiye dikirani kuti gululi ibwerere mwakale.

(3) Chonde yang'anani kulowetsa kwa DC ndi kutulutsa kwa AC kwa inverter, lolani kuti inverter izimitse kwa nthawi yopitilira 30min kuti muwone ngati dera lamagetsi lingathe kubwezeretsedwa palokha, ngati lingathe kubwezeretsedwa palokha, mutha kupitiliza kugwiritsa ntchito, ngati silingabwezeretsedwe, mutha kulumikizana ndi Renac kuti mukonze lipoti.

Chifukwa cha zomwe zachitika:

Ma module ambiri amalumikizidwa motsatizana zomwe zimapangitsa kuti magetsi olowera mbali ya DC apitirire kuchuluka kwamagetsi ogwiritsira ntchito inverter.

Yankho:

(1) Malinga ndi kutentha kwa ma module a PV, kutsika kwa kutentha kozungulira, kumapangitsa kuti magetsi atuluke. Ndi bwino sintha chingwe voteji osiyanasiyana malinga inverter datasheet.

(2) Mumtundu wamtunduwu wamagetsi a inverter, mphamvu ya inverter ndiyokwera kwambiri, ndipo inverter imatha kukhalabe ndi gawo loyambira mphamvu yamagetsi pomwe kuwala kumakhala kochepa m'mawa ndi madzulo, ndipo sikupangitsa kuti voteji ya DC ipitirire malire apamwamba a voteji ya inverter, zomwe zidzatsogolera ku alamu ndi kutseka.

Chifukwa cha zomwe zachitika:

Nthawi zambiri ma module a PV, mabokosi ophatikizika, zingwe za DC, ma inverters, zingwe za AC, ma terminals, ndi magawo ena a mzere kuti awononge kuwonongeka kwafupipafupi kapena kutsekereza kosanjikiza, zolumikizira zingwe zotayirira m'madzi, ndi zina zotero.

Yankho:

Lumikizani gululi, ndi inverter, yang'anani kukana kwagawo lililonse la chingwe pansi, pezani vuto, ndikulowetsa chingwe cholumikizira kapena cholumikizira!

Chifukwa cha zomwe zachitika:

Pali zinthu zambiri zomwe zimakhudza mphamvu yamagetsi yamagetsi ya PV, kuphatikizapo kuchuluka kwa ma radiation a dzuwa, kupendekeka kwa gawo la cell cell, fumbi ndi kutsekeka kwa mthunzi, komanso mawonekedwe a kutentha kwa gawoli.

Mphamvu zamakina ndizochepa chifukwa cha kusanjidwa kolakwika ndi kukhazikitsa.

Smalingaliro:

(1) Yesani ngati mphamvu ya gawo lililonse la PV ndi yokwanira musanayike.

(2) Malo oyikapo sakhala ndi mpweya wabwino, ndipo kutentha kwa inverter sikufalikira nthawi, kapena kumawonekera ku dzuwa mwachindunji, zomwe zimapangitsa kuti kutentha kwa inverter kukhale kokwera kwambiri.

(3) Sinthani mawonekedwe oyika ndikuwongolera gawo la PV.

(4) Onani gawo la mithunzi ndi fumbi.

(5) Musanayike zingwe zingapo, yang'anani voteji yotseguka ya chingwe chilichonse ndi kusiyana kosaposa 5V. Ngati magetsi apezeka kuti ndi olakwika, yang'anani mawaya ndi zolumikizira.

(6) Mukayika, imatha kupezeka m'magulu. Mukapeza gulu lirilonse, lembani mphamvu za gulu lirilonse, ndipo kusiyana kwa mphamvu pakati pa zingwe sikuyenera kupitirira 2%.

(7) Inverter ili ndi mwayi wapawiri wa MPPT, njira iliyonse yolowera mphamvu ndi 50% yokha ya mphamvu yonse. M'malo mwake, njira iliyonse iyenera kupangidwa ndikuyikidwa ndi mphamvu yofanana, ngati ingolumikizidwa ku terminal ya MPPT ya njira imodzi, mphamvu yotulutsa imachepetsedwa.

(8) Kulumikizana koyipa kwa cholumikizira chingwe, chingwecho ndi chachitali kwambiri, waya m'mimba mwake ndi woonda kwambiri, kutayika kwamagetsi, ndipo pamapeto pake kumayambitsa kutayika kwamagetsi.

(9) Dziwani ngati voteji ili mkati mwa voteji pambuyo poti zida zalumikizidwa motsatizana, ndipo mphamvu ya dongosololi idzachepetsedwa ngati voteji ndi yotsika kwambiri.

(10) Kuchuluka kwa chosinthira cha AC cholumikizidwa ndi gridi chamagetsi a PV ndi chochepa kwambiri kuti chikwaniritse zofunikira za inverter.

Chifukwa cha zomwe zachitika:

Chifukwa chake inverter system switch ndizimitsa.

Yankho:

(1) Dinani batani lotsimikizira chophimba cha inverter kuti mulowe mndandanda waukulu - "SysSwitch".

(2) Khazikitsani “SYS Sinthani" ku "Yatsani" ndikudina batani lotsimikizira.

Chifukwa cha zomwe zachitika:

(1)Tvoteji ya PV yake sifika poyambira-pamwambamphamvu ya inverter.

(2)Tmita yake sinalumikizidwe ndi chingwe cholumikizirana kapena kulumikizana ndi kolakwika.

(3) Inverter sichilumikizidwa ndi mita, koma mita imayatsidwa mumenyu yosinthira.

Yankho:

(1)Chonde check ngati inverter PV yolowera voteji ifika poyambira pang'ono-pamwambamphamvu ya inverter.

(2)Chonde check ngati mita yayikidwa kapena ayi, ngati sichoncho, muyenera "Letsani" ntchito ya mita mumenyu ya inverter. Kulowera "Kukhazikitsa" - "Zotsogola" - "Chinthu" - "Kukhazikitsa mita". Khazikitsani "Disable" mu "Meter Setting"

(3)Chonde check ngati chingwe cholumikizira cha mita chilumikizidwa bwino (RS485-A ndi RS485-B zilumikizidwa molondola). Ngati vuto ili pamwambapa lili bwino koma vutokhalani, chonde yesani kusintha mita.

Kufotokozera Zolakwa:

The inverter sadziwa batire, sangathe kuwerenga batire SOC, ndibetri SOC chiwonetseros "N/A".

Chifukwa cha zomwe zachitika:

(1) Kulephera kwa kulumikizana kwa BMS pakati pa inverter ndi batri.

(2) Mabatireis osayatsidwa kapena kulephera kwa BMC.

(3) Batireis osafananizidwandiinverter.

Yankho:

(1)Chonde chekifchingwe cholumikizira cha BMS chimalumikizidwa bwino pakati pa batri ndi inverter. 

(2)Chonde cayi ngatiKusintha kwa mtengo wa DIPimayikidwa bwino painverter. Tadilesi yake yolumikizirana iyenera kukhazikitsidwa moyenera kuti inverter ndi batri zizilumikizana bwino. Pansipa pali chithunzi cha adilesi yolumikizirana dip switch paBMC:

(3)Chonde chekifbatireChithunzi cha BMC LEDis kuyatsa kobiriwira.

(4)If ndiBMCzikhoza kukhala zolakwika.Chonde yesanikuti alowe m'malo.

Chifukwa cha zomwe zachitika:

(1) Inverter sinalumikizidwe ndi mita koma mphamvu ya mita imayikidwa pa inverter

(2) Mawaya olumikizirana mita RS485-A ndi RS485-B amalumikizidwa molakwika.

Yankho:

(1)Chonde cchowotcha mitakukhazikitsa, ngati ayikulumikizana, chonde khalani"Zimitsani" ntchito ya mita mu inverter.

Lowani "Nkhani" - "Kukhazikitsa mita". Ikani "Disable" mu" Meter1Kukhazikitsa”

(2)If mita yakhazikitsidwa kale, fufuzani ngati chingwe cholumikizira cha mita chikugwirizana bwino (RS485-A ndi RS485-B zikugwirizana bwino).

(3)If zonse zomwe zili pamwambazi zili bwino koma vutokhalani, chonde yesani kusintha mita.

Chifukwa cha zomwe zachitika:

Pamene dongosolo alibe PV ndi gululi mphamvu yekha, ndipalibe katundu mphamvukwa mphindi 3, inverter imalowa Idlemode, ichi ndi chodabwitsa.
