Momwe mungasankhire nyumba ya photovoltaic inverter

Pamene photovoltaics imalowa m'nyumba zambiri, ogwiritsa ntchito kunyumba ambiri adzakhala ndi funso asanakhazikitse photovoltaics: Ndi mtundu wanji wa inverter womwe ayenera kusankha?

Mukayika ma photovoltais akunyumba, zinthu 5 zotsatirazi ndizomwe muyenera kuziganizira:

01

onjezerani ndalama

Kodi inverter ndi chiyani? Ndi chipangizo chomwe chimasintha mphamvu ya DC yopangidwa ndi ma module a solar kukhala mphamvu ya AC yomwe ingagwiritsidwe ntchito ndi okhalamo. Chifukwa chake, kusinthika kwamphamvu kwamagetsi ndi nkhani yofunika kwambiri pogula inverter. Pakalipano, zakhala chizolowezi chodziwika bwino kuti mabanja apakhomo atengere mphamvu zapamwamba komanso zamakono zamakono .Chifukwa chake, mabanja amayenera kuganizira kaye ma inverters omwe amasinthidwa kukhala magawo apamwamba kwambiri, omwe ali ndi kutembenuka kwakukulu komanso mtengo wotsika.

Kuphatikiza apo, pali zizindikiro zingapo zofunika zofananira:

Mphamvu ya inverter

Kuchita bwino kwambiri ndi MPPT ya inverter ndizizindikiro zofunika poganizira kupanga mphamvu kwa inverter. Kukwera kochita bwino, kumapangitsanso mphamvu yopanga mphamvu.

Mphamvu yamagetsi yamagetsi ya DC

Kuchulukira kwa ma voliyumu a DC, kutanthauza kuyamba koyambirira ndi kuyimitsidwa mochedwa, kutalikirapo kwa nthawi yopangira magetsi, kupangitsira magetsi kumakwera.

Kulondola kwaukadaulo wa MPPT

Ukadaulo wotsatira wa MPPT uli ndi kulondola kwambiri, kuyankha mwachangu, kumatha kusintha kusintha kwachangu pakuwunikira, ndikuwongolera mphamvu zamagetsi.

02

Kusintha kosinthika

Chilengedwe cha nyumba zopangira magetsi ndizovuta kwambiri. Mavuto monga ma terminals amagetsi akumidzi ndi kugwiritsa ntchito mphamvu kumayambitsa inverter AC overvoltage, undervoltage ndi ma alarm ena. Inverter iyenera kukhala ndi chithandizo chofooka cha gridi, mawonekedwe osinthika a grid voltage, komanso kutsika kwamagetsi. , chipukuta misozi champhamvu ndi ntchito zina zochepetsera ma alarm. Chiwerengero cha ma MPPT ndi chimodzi mwa zizindikiro zofunika kuziganizira:Kusintha kwa ma MPPT amitundu yambiri kumatha kusinthidwa mosinthika molingana ndi zinthu monga mawonekedwe osiyanasiyana, madenga osiyanasiyana, ndi mawonekedwe osiyanasiyana azinthu.

03

unsembe mosavuta

Zitsanzo zazing'ono ndi zopepuka ndizosavuta kuziyika. Panthawi imodzimodziyo, muyenera kusankha inverter yomwe yakhazikitsidwa mufakitale musanachoke pafakitale. Ikayikidwa kunyumba kwa wogwiritsa ntchito, imatha kugwiritsidwa ntchito mukayatsa, zomwe zimapulumutsa nthawi yosokoneza komanso ndizosavuta.

04

otetezeka ndi okhazikika

Popeza ma inverters ambiri amaikidwa panja, IP yopanda madzi komanso yopanda fumbi ndi index yoteteza yomwe siingathe kunyalanyazidwa, yomwe ingateteze bwino inverter ku zotsatira zoyipa m'malo ovuta.Sankhani inverter yokhala ndi IP65 kapena kupitilira apoonetsetsani kuti inverter imagwira ntchito bwino.

Pankhani ya ntchito zoteteza, kuwonjezera pa ntchito zofunika monga kusintha kwa DC, kutetezedwa kwamphamvu kwambiri, chitetezo chafupipafupi cha AC, chitetezo cha AC chowonjezera, komanso chitetezo chotchinjiriza, pali ntchito zina zitatu zofunika kwambiri:

#

DC arc intelligent kuzindikira AFCI

Imatha kuzindikira molondola ma arcing, kutseka mwachangu, kupewa moto, ndikuteteza chitetezo cha ogwiritsa ntchito.

#

Kulakwitsa kujambula ntchito

Yang'anani ndikujambulitsa ma voliyumu ndi ma waveform apano kumbali ya AC ya inverter munthawi yeniyeni kuti mupeze zovuta mwachangu.

#

Kusanthula kwa Smart IV ndi Kuzindikira

Imatha kupeza zolakwika za zingwe ndikuzindikira zovuta. Ndi zitsimikizo zingapo, malo opangira magetsi amatha kugwira ntchito mokhazikika, kupatsa ogwiritsa ntchito mtendere wamalingaliro.

05

Smart Management

M'nthawi yamakono yamakono, zida zanzeru zimatha kupatsa ogwiritsa ntchito mosavuta. Mitundu ya inverterokonzeka ndi nsanja kasamalidwe wanzeruszitha kubweretsa kumasuka kwa ogwiritsa ntchito mu kasamalidwe ka siteshoni yamagetsi: Choyamba, mutha kugwiritsa ntchito foni yanu yam'manja kuyang'anira malo opangira magetsi, kuyang'ana data yoyendetsera siteshoni yamagetsi nthawi iliyonse komanso kulikonse, ndikumvetsetsa momwe malo opangira magetsi alili munthawi yake. Panthawi imodzimodziyo, opanga amatha kupeza mavuto pogwiritsa ntchito matenda akutali, kusanthula zomwe zimayambitsa zolephera, kupereka mayankho, ndi kuthetsa mavuto patali panthawi yake.
