Monga gawo lofunikira la malo onse opangira magetsi, inverter ya solar imagwiritsidwa ntchito kuzindikira zida za DC ndi zida zolumikizidwa ndi grid. Kwenikweni, magawo onse amagetsi amatha kuzindikirika ndi fayilo yainverter ya dzuwa. Ngati vuto lachitika, thanzi la zida zothandizira pa siteshoni yamagetsi zitha kuwunikiridwa kudzera mu chidziwitso chobwezeredwa ndi solar inverter. Zotsatirazi ndi chidule cha chidziwitso chodziwika bwino ndi njira zothandizira ma inverters a dzuwa a photovoltaic.
Palibe kulumikizana kwa mains
chifukwa cha vuto:
Zimatanthawuza kuti mphamvu ya AC sinalumikizidwe kapena chowotcha cha AC sichimalumikizidwa, kuchititsa kutiinverter ya dzuwakulephera kuzindikira mphamvu yamagetsi ya AC.
Yankho:
1. Dziwani ngati gululi lamagetsi latha mphamvu. Ngati ndi choncho, dikirani kuti gridi yamagetsi iyambirenso magetsi.
2. Ngati magetsi ochokera ku gridi yamagetsi ndi abwinobwino, gwiritsani ntchito AC voltage range ya multimeter kuti muwone ngati AC output voltage ndi yachibadwa. Choyamba, yesani doko lotulutsa ma solar inverter ndikuwunika ngati pali vuto lililonse kumbali yotulutsa ya solar inverter. Ngati palibe vuto, zikutanthauza kuti pali yopuma dera kunja AC mbali. Muyenera kuyang'ana ngati chosinthira mpweya, chosinthira mpeni, choteteza kwambiri komanso choteteza pansi pamagetsi ndi ma switch ena achitetezo awonongeka kapena otseguka.
Mphamvu ya AC yatha
chifukwa cha vuto:
Pamene mphamvu ya photovoltaic imagwirizanitsidwa ndi gridi yamagetsi yamagetsi, mphamvu ya malo olowera idzawonjezeka. Kukana kwakukulu kwa mkati kwa gridi yamagetsi, kuyamikira kwakukulu uku. Kuyandikira kwa thiransifoma, kukana kwa mzere wocheperako, kusinthasintha kwa gridi kudzakhala kochepa, ndipo kuyandikira kumapeto kwa gridi, mizere yayitali, kusinthasintha kwamagetsi. Choncho, pamene ainverter ya dzuwaimalumikizidwa ndi gridi kutali ndi thiransifoma, malo ogwirira ntchito a gridi ya solar inverter adzakhala osauka kwambiri. Pambuyo malire apamwamba a magetsi oyendetsa magetsi a solar inverter adutsa, inverter ya dzuwa idzanena zolakwika ndikusiya kugwira ntchito. Malinga ndi specifications luso photovoltaic mphamvu m'badwo gululi olumikizidwa ndi ma inverters dzuwa (NB/T 32004-2018), zofunika overvoltage/undervoltage chitetezo pa AC linanena bungwe: Pamene voteji pa AC linanena bungwe terminal ya inverter dzuwa kuposa Mtundu wovomerezeka wamagetsi wa gridi, inverter ya solar imaloledwa kutseka. Yatsani magetsi ku gridi yamagetsi ndikutumiza chizindikiro chochenjeza ikadulidwa. Inverter ya solar iyenera kuyamba ndikugwira ntchito moyenera mphamvu ya gridi ikabwerera kumtundu wovomerezeka.
Yankho:
1. Yesetsani kuyika malo olowera magetsi a photovoltaic pafupi ndi mapeto otuluka a transformer kuti muchepetse kutayika kwa mzere.
2. Yesani kufupikitsa kutalika kwa mzere wa inverter ya solar AC linanena bungwe kumapeto, kapena gwiritsani ntchito zingwe zokulirapo zamkuwa kuti muchepetse kusiyana kwamagetsi pakati pa inverter ya solar ndi grid.
3. Tsopano ma inverters ambiri omwe amalumikizidwa ndi gridi ali ndi ntchito yoyendetsera magetsi a AC. Mutha kulumikizana ndi wopanga kuti akulitse voteji ya AC kuti igwirizane ndi kusinthasintha kwamagetsi a gridi.
4. Ngati n'kotheka, mphamvu yamagetsi ya transformer ikhoza kuchepetsedwa moyenera.
Low insulation kukana
chifukwa cha vuto:
Inverter ya solar ili ndi ntchito yozindikira kutsekeka kwa mbali ya DC. Ikazindikira kuti kutsika kwabwino komanso koyipa kwa DC ndikotsika kuposa 50kΩ, inverter ya solar idzanena kuti "PV insulation impedance ndiyotsika kwambiri" kuteteza thupi la munthu kuti lisakhudze gawo lamoyo la gululo ndi pansi pamtunda. nthawi yomweyo, kuchititsa chiopsezo kugwedezeka kwa magetsi. Zomwe zimakhudzidwa ndi izi: kutayikira kwa gawo la DC; chingwe kutchinjiriza kuwonongeka, moyo poyera mbali chinyezi; chigawo cha bulaketi maziko ndi osauka; nyengo ndi malo opangira magetsi chinyontho ndichokwera kwambiri, etc.
Yankho:
Lumikizani zowononga AC ndi DC, gwiritsani ntchito wrench yapadera ya MC4 kuti muchotse mitengo yabwino komanso yoyipa ya chingwe choyesera cha DC kuti muwonetsetse kuti bulaketi yachigawocho yakhazikika modalirika, gwiritsani ntchito ma multimeter megohm osiyanasiyana, lumikizani mayeso ofiira ku zabwino. mtengo wa chingwe, ndi mayeso wakuda amatsogolera pansi, werengani kuwerenga kwa impedance kwa mtengo uliwonse wabwino pansi, ndiyeno mulumikizanitse mayeso ofiira kumtengo woyipa wa chingwe, kenako werengani kuwerenga kwa impedance kwa chilichonse cholakwika. mtengo pansi. Ngati ndi yayikulu kuposa 50kΩ, zimaganiziridwa kuti kutsekemera kwa zingwe ndikodalirika. Ngati ndi yocheperapo kapena yofanana ndi 50kΩ, zimaganiziridwa kuti pali vuto ndi kutsekereza zingwe. Mutha kuyang'ana momwe chingwe cha chingwecho chilili padera kuti muwone ngati pali kuwonongeka kapena kusalumikizana bwino. Kutsika kwa insulation impedance nthawi zambiri kumatanthauza kuti mitengo yabwino ndi yoyipa imakhala yochepa kwambiri pansi.
Kutuluka kwa madzi ndikokwera kwambiri
chifukwa cha vuto:
Solar inverter leakage current yozindikira module imazindikira kuti kutayikira kwapano ndi kwakukulu kwambiri. Pofuna kuteteza chitetezo chaumwini, imasiya kugwira ntchito ndikufotokozera zolakwika.
Yankho:
1. Chotsani cholowetsa cha PV, yambitsaninso makinawo, ndikuwona ngati makinawo angabwerere mwakale.
2. Yang'anani ngati waya wapansi wa AC walumikizidwa ku waya wamoyo, yesani ngati voteji pakati pa waya wapansi ndi mawaya amoyo ndi abwinobwino, kapena gwiritsani ntchito chowunikira chomwe chikutuluka kuti muzindikire.
3. Ngati palibe kugwirizana pakati pa waya woyezera pansi ndi waya wamoyo, ndizotheka kuti makinawo akutha, ndipo muyenera kulankhula ndi wopanga kuti akuthandizeni.
Mphamvu ya DC ndiyokwera kwambiri
chifukwa cha vuto:
Pali zigawo zambiri zolumikizidwa mu chingwe chimodzi cha PV, zomwe zimapangitsa kuti voteji ipitirire malire a PV voltage kumtunda kwa inverter ya solar.
Yankho:
Yang'anani magawo a inverter ya solar, dziwani kuchuluka kwa voliyumu ya DC, kenako yesani ngati voteji yotseguka ya chingwe ili mkati mwazovomerezeka za solar inverter. Ngati idutsa mulingo wololeka, chepetsani kuchuluka kwa zigawo zachingwe.
Momwemonso, ngati magetsi a PV anenedwa kuti ndi otsika kwambiri, fufuzani ngati chiwerengero cha ma modules omwe amagwirizanitsidwa mndandanda ndi ochepa kwambiri, kapena ngati mizati yabwino ndi yolakwika ya chingwe imalumikizidwa mozungulira, ma terminals ndi otayirira, kukhudzana. ndi osauka, kapena chingwe ndi lotseguka.
Palibe chowonetsera pazenera la inverter ya solar
chifukwa cha vuto:
1. Palibe kulowetsedwa kwa DC kapena kulephera kwa magetsi othandizira, LCD ya solar inverter imayendetsedwa ndi DC, ndipo gawo lamagetsi silingathe kufika pamagetsi oyambira dzuwa.
2. Malo olowera a PV amalumikizidwa mobwerera. Ma terminal a PV ali ndi mizati yabwino komanso yoyipa, yomwe iyenera kugwirizana ndipo sizingagwirizane ndi magulu ena.
3. Kusintha kwa DC sikutsekedwa.
4. Chigawo chimodzi chimachotsedwa, zomwe zimapangitsa kuti zingwe zina zisagwire ntchito.
Yankho:
1. Gwiritsani ntchito ma multimeter kuti muyese mphamvu yamagetsi ya DC ya inverter ya solar. Mphamvu yamagetsi ikakhala yabwinobwino, voteji yonse ndi kuchuluka kwa ma voltages a gawo lililonse.
2. Ngati palibe magetsi, fufuzani ngati chosinthira cha DC, ma wiring terminals, ma chingwe, zigawo, ndi zina zotero.
Kuwunika nkhani
chifukwa cha vuto:
Wosonkhanitsa ndi solar inverter sakulankhulana; wosonkhanitsa alibe mphamvu: vuto la chizindikiro pamalo oikapo; zifukwa zamkati za wosonkhanitsa.
Yankho:
1. Onani ngati kulumikizana pakati pa osonkhanitsa ndiinverter ya dzuwandi zachilendo, ndi kuona kulankhulana chizindikiro kuwala;
2. Yang'anani mphamvu ya chizindikiro chapafupi. Malo omwe ali ndi zizindikiro zofooka ayenera kugwiritsa ntchito tinyanga tambiri.
3. Jambulani nambala yolondola yosonkhanitsa
4. Pamene palibe mavuto ndi zikhalidwe zakunja, ngati wosonkhanitsa sakuyankha kugwirizana kulikonse, zikhoza kuganiziridwa kuti pali kulephera kwamkati kwa wosonkhanitsa.
Fotokozerani mwachidule
Pamwambapa, mavuto omwe amakumana nawoinverter ya dzuwas m'mapulojekiti a photovoltaic amawunikidwa ndipo malingaliro ena amaperekedwa, molunjika pakumvetsetsa zomwe zimayambitsa ndi njira zochizira zovuta zomwe zimachitika. Panthawi imodzimodziyo, pakukonza tsiku ndi tsiku kwa malo opangira magetsi, njira zonse zotetezera chitetezo ndi ntchito yabwino yokhazikika ndi kukonzanso zimafunika. Ndiwonso chinsinsi chowonetsetsa kuti malo opangira magetsi amapeza ndalama.
Monga wopanga ma inverter a solar omwe ali ndi zaka 12 zaukadaulo, Amensolar imapereka ntchito 24/7 pambuyo pogulitsa, kulandila ogulitsa kuti agwirizane ndi netiweki yathu ndikukulira limodzi.
