Ninde DC splar kabili nibyiza kuri sisitemu yizuba

Guhitamo DC iburyoumugozi w'izubaingano muri sisitemu yifoto yizuba ningirakamaro kubikorwa byombi n'umutekano. Insinga zigomba kuba zingana neza ukurikije ikigezweho na voltage ikoreshwa muri sisitemu. Ubushinwa H1Z2Z2-K Imirasire y'izuba hamwe nubwiza buhanitse 62930 IEC 131 umugozi wizuba urakunzwe.

Ubunini bwumugozi wa kabili mubusanzwe ni mm2. Aka gace kagereranya ubuso bwububiko bwa kabili. Ingano yinsinga zisanzwe zifotora izuba ni: 2.5-4-6-10-16-25-35 mm2.

 Hariho ubwoko bukurikira bwinsinga:

1. hagati ya bateri na inverter, 35 cyangwa 25 mm2

2. kuva kumirasire yizuba kugirango igenzure kuri bateri 10, 6 na 4 mm2.

3. kuva muri inverter kugera kuri gride, 4 na 2,5 mm2

Kuri buri cyiciro, ugomba gukoresha amperage ikwiye, uburebure bwa kabili, hamwe nigihombo cyemewe (nimbaraga). Kugirango umenye diameter yibanze ya kabili ihagaze, reba insulasiyo ya kabili. Hano hari ikimenyetso kuri kabili yerekana ubunini bwumugozi.

62930 IEC 131 insinga y'izuba Ingano ya kabili ifite 2.5 - 4 - 6 - 10 - 16 - 25 - 35 mm2, Umuringa Wumuringa Double Core Solar Cable Ingano ifite 2 * 2.5mm2,2 * 4mm2,2 * 6mm2.2 * 10mm2.Ubushinwa H1Z2Z2 -K Imirasire y'izuba ifite 2.5 - 4 - 6 - 10 - 16 - 25 - 35 mm2.

Intsinga zikoresha amashanyarazi (DC) itangwa nizuba ryizuba kandi rikabikwa muri bateri. Harimo:

Imiyoboro ya PV Module:Izi nsinga zihuza imirasire yizuba hamwe nubushakashatsi bwishyuza, bugenga imigendekere yingufu za banki ya batiri. Imiyoboro ya PV mubisanzwe ni 10-12 AWG (American Wire Gauge), insinga zizuba zikubye kabiri zagenewe gukemura ingufu za DC ziva mumirasire y'izuba.

Umugozi wa Batiri:Intsinga ya bateri ihuza banki ya bateri na mugenzuzi wishyuza na inverter. Bashinzwe gutwara ingufu za DC hagati yibi bice. Imigozi ya bateri muri rusange nini mubunini, kuva kuri 2-4 / 0 AWG, bitewe nubushobozi bwa sisitemu nubu bakeneye gutwara.

Intsinga ya Inverter:Izi nsinga zihuza inverter na banki ya bateri, ikohereza ingufu za DC kuva muri bateri kugeza muri inverter. Intsinga ya Inverter isanzwe isa nubunini ninsinga za bateri, mubisanzwe 2-4 / 0 AWG, kugirango ikore amashanyarazi asabwa hagati ya banki ya bateri na inverter.
