Yadda ake zabar igiyoyin photovoltaic na gida ta fuskar tattalin arziki

A cikin tsarin photovoltaic, yawan zafin jiki na ACna USBHakanan ya bambanta saboda yanayi daban-daban da aka sanya layin.Nisa tsakanin inverter da ma'aunin haɗin grid ya bambanta, yana haifar da raguwar ƙarfin lantarki daban-daban akan kebul.Dukansu zafin jiki da raguwar wutar lantarki zasu shafi asarar tsarin.Sabili da haka, ya zama dole don tsara madaidaicin waya diamita na fitarwa na halin yanzu na inverter, kuma yayi la'akari da mahimmancin dalilai daban-daban, don rage saka hannun jari na farko na tashar wutar lantarki ta photovoltaic da rage asarar layin na tsarin.
Lokacin zayyana da zaɓin igiyoyi, sigogin fasaha kamar ƙididdige ƙarfin ɗaukar nauyi na yanzu, ƙarfin lantarki, da zazzabi na kebul ana la'akari da su.A lokacin shigarwa, ana kuma la'akari da diamita na waje, radius na lanƙwasa, rigakafin wuta, da dai sauransu na kebul.Lokacin ƙididdige farashi, la'akari da farashin kebul.
1. Sakamakon fitarwa na inverter ya kamata ya kasance daidai da ƙarfin ɗaukar nauyin na USB
Wurin fitarwa na inverter yana ƙaddara ta ikon.Mai jujjuya lokaci-lokaci ɗaya na yanzu = iko / 230, inverter na yanzu = iko / (400 * 1.732), da wasu inverters kuma ana iya yin lodi da yawa sau 1.1.
Ƙarfin ɗaukar nauyin kebul na yanzu yana ƙayyade ta kayan aiki, diamita na waya da zafin jiki.Akwai nau'ikan igiyoyi guda biyu: wayar tagulla da waya ta aluminum, kowannensu yana da amfani.Daga hangen zaman lafiya, ana ba da shawarar yin amfani da wayar jan ƙarfe don fitarwa na kebul na AC na inverter, kuma ana zaɓin waya mai laushi BVR don lokaci-lokaci ɗaya.Waya, PVC rufi, jan karfe core (laushi) zane irin ƙarfin lantarki aji ne 300/500V, uku-lokaci zabi 450/750 irin ƙarfin lantarki (ko 0.6kV / 1kV) aji YJV, YJLV irradiated XLPE rufi PVC Sheathed ikon na USB, da dangantaka tsakanin yanke mai gudanarwa da zafin jiki, idan yanayin zafin jiki ya wuce 35 ° C, yakamata a rage ikon halin yanzu da kusan 10% ga kowane karuwar zafin jiki na 5 ° C;idan yanayin yanayi ya yi ƙasa da 35 ° C, zafin jiki Lokacin da zafin jiki ya ragu da 5 ° C, za a iya ƙara yawan izinin yanzu da kusan 10%.Gabaɗaya, idan an shigar da kebul ɗin a cikin gida mai iska.
2. Kebultsarin tattalin arziki
A wasu wurare, mai jujjuyawar yana da nisa daga wurin haɗin grid.Kodayake kebul na iya saduwa da buƙatun ƙarfin ɗaukar nauyi na yanzu, asarar layin yana da girma sosai saboda dogon kebul.Mafi girma da warp, ƙananan juriya na ciki.Amma kuma la'akari da farashin na USB, da m diamita na inverter AC fitarwa shãfe haske tashoshi.
