Kodi ma inverters a photovoltaic ndi ati?

1. Kutembenuka kochepa-kutaya
Chimodzi mwazinthu zofunika kwambiri za inverter ndikusinthika kwake, mtengo womwe umayimira kuchuluka kwa mphamvu zomwe zimayikidwa pomwe magetsi achindunji abwezedwa ngati alternating current, ndipo zida zamakono zimagwira ntchito pafupifupi 98%.
2. Mphamvu kukhathamiritsa
Mphamvu yopindika ya module ya PV imadalira kwambiri mphamvu yowunikira komanso kutentha kwa gawoli, mwa kuyankhula kwina, pamikhalidwe yomwe imasintha tsiku lonse, chifukwa chake, inverter iyenera kupeza ndikuwona mosalekeza zomwe zili bwino pamagetsi. Khalidwe lopindika.opareshoni kuti atenge mphamvu yayikulu kuchokera ku gawo la PV nthawi iliyonse.
3. Kuyang'anira ndi Chitetezo
Kumbali imodzi, inverter imayang'anira mphamvu ya magetsi a photovoltaic power plant, ndipo kumbali ina, imayang'aniranso gridi yomwe imagwirizanitsidwa.Chifukwa chake, ngati pali vuto ndi gululi, iyenera kutulutsa mbewuyo nthawi yomweyo kuchokera pagululi chifukwa cha chitetezo, malingana ndi zofunikira za woyendetsa gridi wamba.
Kuphatikiza apo, nthawi zambiri, inverter imakhala ndi chipangizo chomwe chimatha kusokoneza mosavutikira kuyenda kwa ma module a PV.Popeza gawo la PV limakhala logwira ntchito nthawi zonse likatulutsa kuwala, silingathe kuzimitsidwa.Ngati zingwe za inverter zimachotsedwa panthawi yogwira ntchito, ma arcs owopsa amatha kupanga ndipo ma arcs awa sangazimitsidwe ndi pompopompo mwachindunji.Ngati wowononga dera akuphatikizidwa mwachindunji mu converter pafupipafupi, unsembe ndi mawaya ntchito akhoza kuchepetsedwa kwambiri.
4. Kulankhulana
Mawonekedwe olankhulana paotembenuza pafupipafupi amalola kuwongolera ndi kuyang'anira magawo onse, deta yogwiritsira ntchito ndi zotuluka.Kudzera pa intaneti, ma fieldbus a mafakitale monga RS 485, ndizotheka kupeza deta ndikuyika magawo a inverter.Nthawi zambiri, deta imatengedwa kudzera pa cholembera cha data chomwe chimasonkhanitsa deta kuchokera ku ma inverters angapo ndipo, ngati pakufunika, amawatumiza kumalo aulere pa intaneti.
5. Kuwongolera kutentha
Kutentha kwa inverter kesi kumakhudzanso kutembenuka mtima, ngati kukwera kuli kwakukulu, inverter iyenera kuchepetsa mphamvu, ndipo nthawi zina mphamvu ya module yomwe ilipo singagwiritsidwe ntchito mokwanira.Kumbali imodzi, malo oyikapo amakhudza kutentha - malo ozizira mosalekeza ndi abwino.Kumbali inayi, zimadalira mwachindunji ntchito ya inverter: ngakhale 98% yogwira ntchito imatanthauza 2% kutaya mphamvu.Ngati mphamvu ya chomera ndi 10 kW, kutentha kwakukulu kumakhalabe 200 W.
6. Chitetezo
Nyumba yotetezedwa ndi nyengo, yokhala ndi chitetezo cha IP 65, imalola kuti inverter iyikidwe panja pamalo aliwonse omwe mukufuna.Ubwino: Mukayandikira kwambiri ma module omwe amatha kuyikidwa mu inverter, ndiye kuti mumawononga ndalama zochepa pamawaya okwera mtengo a DC.
