# Menene bambanci tsakanin inverter na kashe-grid da inverter mai haɗin grid? #

Kashe-grid inverters da grid-connected inverters su ne manyan nau'ikan inverters guda biyu a cikin tsarin hasken rana. Ayyukan su da yanayin aikace-aikacen sun bambanta sosai:

Kashe-grid Inverter
Ana amfani da inverter na kashe-grid a tsarin hasken rana waɗanda ba su da alaƙa da grid na gargajiya. Ana amfani da su sau da yawa tare da tsarin ajiyar baturi don adana yawan wutar lantarki da aka samar da hasken rana.

Babban Aiki: Maida halin yanzu kai tsaye (DC) wanda filayen hasken rana ko wasu na'urorin makamashi masu sabuntawa zuwa madaidaicin halin yanzu (AC) don amfani a gidaje ko na'urori.

Cajin baturi: Yana da ikon sarrafa cajin baturi, sarrafa tsarin caji da cajin baturin, da kuma kare rayuwar baturi.

Aiki mai zaman kansa: baya dogara ga grid na wutar lantarki na waje kuma yana iya aiki da kansa lokacin da babu wutar lantarki. Ya dace da wurare masu nisa ko wurare tare da grid masu ƙarfi marasa ƙarfi.

Grid-tie Inverter
Ana amfani da inverters na tie a cikin tsarin hasken rana da aka haɗa da grid na jama'a. An ƙera wannan inverter don haɓaka jujjuyawar makamashin hasken rana zuwa wutar lantarki da kuma ciyar da shi cikin grid.

Babban aiki: Maida wutar lantarki ta DC da aka samar ta hanyar hasken rana zuwa ikon AC wanda ya dace da ma'auni kuma ciyar da shi kai tsaye zuwa gidan wutan lantarki ko kasuwanci.

Babu ajiyar baturi: Yawanci ba a yi amfani da su tare da tsarin baturi saboda babban manufar su shine isar da wuta kai tsaye zuwa grid.

Ra'ayin makamashi: Za'a iya siyar da wutar lantarki da yawa zuwa grid, kuma masu amfani za su iya rage kuɗin wutar lantarki ta hanyar mitar abinci (Net Metering).

Dogaran Grid: Masu jujjuyawar kashe-grid suna aiki gaba ɗaya masu zaman kansu daga grid, yayin da grid mai ɗaure inverters suna buƙatar haɗi zuwa grid.
Ƙarfin ajiya: Tsarin kashe-grid yawanci yana buƙatar batura don adana makamashi don tabbatar da ci gaba da samar da wutar lantarki; Tsarukan haɗin grid suna aika makamashin da aka samar kai tsaye zuwa grid kuma baya buƙatar ajiyar baturi.
Fasalolin tsaro: Masu juyawa masu haɗin grid suna da mahimman ayyukan aminci, kamar kariya ta tsibiri (hana ci gaba da watsa wutar lantarki zuwa grid lokacin da grid ɗin ya ƙare), yana tabbatar da amincin grid ɗin kulawa da ma'aikata.

Yanayin aikace-aikacen: Tsare-tsaren kashe-tsari sun dace da wuraren da ba su da damar yin amfani da grid ɗin wuta ko rashin ingancin sabis na grid; tsarin haɗin grid sun dace da birane ko kewayen birni tare da tsayayyun ayyukan grid wuta.

Wanne nau'in inverter aka zaɓa ya dogara da takamaiman buƙatun mai amfani, wurin yanki, da buƙatar tsarin ikon yancin kai.
