Ndi chitukuko cha teknoloji ya Cell ndi PV module, matekinoloje osiyanasiyana monga cell cutter cell, shingling module, bi-face module, PERC, ndi zina zotero. Mphamvu zotulutsa ndi zamakono za module imodzi zawonjezeka kwambiri. Izi zimabweretsa zofunikira zapamwamba kwa ma inverters.
1.High-Power Modules yomwe imafuna Kusinthasintha Kwamakono Kwamakono kwa Inverters
Imp ya ma module a PV inali pafupi ndi 8A m'mbuyomu, kotero kuti mphamvu yowonjezera yowonjezera ya inverter nthawi zambiri inali pafupi 9-10A. Pakalipano, Imp ya 350-400W ma modules amphamvu kwambiri adutsa 10A yomwe ndiyofunika kusankha inverter yokhala ndi 12A yolowera panopa kapena yapamwamba 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 module ya 370W ifika ku 10.86A. Tiyenera kuwonetsetsa kuchuluka kwaposachedwa kwa inverter kupitilira Imp ya module ya PV.
2.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.
Zowonjezera zomwe zilipo panopa za Renac R3 Note Series 4-15K inverter ya magawo atatu ndi 12.5A, yomwe imatha kukwaniritsa zofunikira za ma module a PV apamwamba kwambiri.
Kutenga 370W zigawo monga chitsanzo sintha 4kW, 5kW, 6kW, 8kW, 10kW machitidwe motero. Zofunikira zazikulu za ma inverters ndi awa:
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 ndikusunga dongosolo labwinobwino, zomwe zimapangitsa kuti ndalama zanu zikhale zopindulitsa.
Masinthidwe omwe akulimbikitsidwa ali motere:
Malingana ngati voteji yotseguka yotseguka ya chingwe ndi DC panopa ali mkati mwa kulolerana kwa makina, inverter imatha kugwira ntchito yolumikizana ndi grid.
1.Maximum DC panopa ya chingwe ndi 10.86A, yomwe ili yochepa kuposa 12.5A.
2.Maximum otseguka ozungulira magetsi a chingwe mkati mwa MPPT ya inverter.
Chidule
Ndi kuwongolera kosalekeza kwa mphamvu zama module, opanga ma inverter amayenera kuganizira zofananira ndi ma inverters ndi ma module. Posachedwapa, ma module a 500W + PV okhala ndi apamwamba kwambiri akuyenera kukhala msika waukulu kwambiri. Renac ikupita patsogolo ndi luso komanso ukadaulo ndipo ikhazikitsa zinthu zaposachedwa kuti zigwirizane ndi gawo la Power PV lapamwamba.
