Ndi chitukuko cha teknoloji ya Cell ndi PV module, matekinoloje osiyanasiyana monga theka la cell cut, shingling module, bifacial module, PERC, ndi zina zotero.Mphamvu zotulutsa ndi zamakono za module imodzi zawonjezeka kwambiri.Izi zimabweretsa zofunikira zapamwamba kwa ma inverters.
Ma Module Amphamvu Akuluakulu omwe amafunikira Kusinthika Kwamakono Kwamakono kwa Ma Inverters
Imp ya ma module a PV inali pafupi ndi 10-11A m'mbuyomu, kotero kuti mphamvu yowonjezera yowonjezera ya inverter nthawi zambiri inali pafupi 11-12A.Pakalipano, Imp ya 600W + ma modules amphamvu kwambiri adutsa 15A yomwe ndi yofunikira kusankha inverter yokhala ndi 15A yolowera panopa kapena kupitilirapo kuti ikwaniritse mphamvu ya PV module.
Gome lotsatirali likuwonetsa magawo amitundu ingapo yama module amphamvu kwambiri omwe amagwiritsidwa ntchito pamsika.Titha kuwona kuti Imp ya 600W bifacial module imafika ku 18.55A, yomwe ili kunja kwa malire ambiri a zingwe zosinthira pamsika.Tiyenera kuwonetsetsa kuti kuchuluka kwaposachedwa kwa inverter ndikokulirapo kuposa Imp ya module ya PV.
Pamene mphamvu ya module imodzi ikuwonjezeka, chiwerengero cha zingwe zolowetsa za inverter zikhoza kuchepetsedwa moyenera.
Ndi kuwonjezeka kwa mphamvu za PV modules, mphamvu ya chingwe chilichonse idzawonjezekanso.Pansi pa chiŵerengero chofanana cha mphamvu, chiwerengero cha Zingwe Zolowetsa pa MPPT chidzachepa.
Ndi Solution iti yomwe Renac angapereke?
Mu April 2021, Renac anatulutsa mndandanda watsopano wa inverters R3 Pre mndandanda 10 ~ 25 kW. Pogwiritsa ntchito luso lamakono lamagetsi amagetsi ndi luso lamakono lamakono kuti awonjezere mphamvu yamagetsi yamagetsi ya DC kuchokera ku 1000V yapachiyambi mpaka 1100V, imalola kuti makinawo agwirizane kwambiri. mapanelo, komanso angapulumutse ndalama chingwe.Nthawi yomweyo, ili ndi 150% DC oversize mphamvu.Zomwe zimalowetsa panopa za inverter iyi ndi 30A pa MPPT, zomwe zingathe kukwaniritsa zofunikira za ma modules amphamvu kwambiri a PV.
Kutenga 500W 180mm ndi 600W 210mm bifacial modules monga chitsanzo sintha 10kW, 15kW, 17kW, 20kW, 25kW machitidwe motero.Zofunikira zazikulu za ma inverters ndi awa:
Zindikirani:
Tikakonza dongosolo la dzuwa, tikhoza kuganizira za DC oversize.Lingaliro la DC oversize limavomerezedwa kwambiri pamapangidwe a solar system.Pakadali pano, zopangira magetsi za PV padziko lonse lapansi ndizokulirapo kale pakati pa 120% ndi 150%.Chimodzi mwazifukwa zazikulu zochulukitsira jenereta ya DC ndikuti mphamvu zongoyerekeza za ma module nthawi zambiri sizikwaniritsidwa kwenikweni.M'madera ena omwe mulibe kuwala kokwanira, kuchulukitsa kwabwino (kuwonjezera mphamvu ya PV kuti muwonjezere maola odzaza makina a AC) ndi njira yabwino.Mapangidwe abwino opitilira muyeso amatha kuthandizira makinawo kuti ayambe kukhazikika komanso kuti makina azikhala abwino, zomwe zimapangitsa kuti ndalama zanu zikhale zopindulitsa.
Masinthidwe omwe akulimbikitsidwa ali motere:
Malinga ndi kuwerengera, ma inverters a Renac amatha kufanana bwino ndi mapanelo a 500W ndi 600W.
Chidule
Ndi kuwongolera kosalekeza kwa mphamvu zama module, opanga ma inverter amayenera kuganizira zofananira ndi ma inverters ndi ma module.Posachedwapa, ma module a 210mm wafer 600W+ PV okhala ndi aposachedwa atha kukhala msika waukulu kwambiri.Renac ikupita patsogolo ndi luso komanso ukadaulo ndipo iyambitsa zinthu zonse zatsopano kuti zigwirizane ndi ma module apamwamba a Power PV.
