Ko te kaupapa matua o te whakaputa hiko photovoltaic o te rā he hangarau e huri tika ana i te pūngao mārama ki te pūngao hiko mā te whakamahi i te pānga photovoltaic o te atanga semiconductor. Ko te wāhanga matua o tēnei hangarau ko te pūtau solar. Ka tākaihia, ka tiakina hoki ngā pūtau solar i roto i te raupapa hei hanga i tētahi kōwae pūtau solar nui, kātahi ka honoa ki tētahi kaiwhakahaere hiko, ki tētahi mea rānei hei hanga i tētahi taputapu whakaputa hiko photovoltaic. Ka kiia te tukanga katoa he pūnaha whakaputa hiko photovoltaic. Ko te pūnaha whakaputa hiko photovoltaic he mea tito mai i ngā huinga pūtau solar, ngā kete pākahiko, ngā kaiwhakahaere utu me te tuku, ngā kaitahuri photovoltaic solar, ngā pouaka whakakotahi me ētahi atu taputapu.
He aha i whakamahia ai he inverter i roto i te pūnaha whakaputa hiko photovoltaic solar?
He taputapu te kaitahuri hiko e huri ana i te iahiko tika ki te iahiko tauutuutu. Ka whakaputahia e ngā pūtau rā te mana DC i te rā, ā, ko te mana DC e rongoatia ana i roto i te pākahiko he mana DC anō hoki. Heoi, he nui ngā herenga o te pūnaha tuku hiko DC. Kāore e taea te whakakaha i ngā kawenga AC pēnei i ngā rama fluorescent, ngā pouaka whakaata, ngā pouaka whakamātao, me ngā pā hiko i roto i te oranga o ia rā e te mana DC. Kia whānuitia ai te whakamahinga o te whakaputa hiko photovoltaic i roto i tō tātou oranga o ia rā, he mea nui ngā kaitahuri hiko ka taea te huri i te iahiko tika ki te iahiko tauutuutu.
Hei wāhanga nui o te whakaputa hiko photovoltaic, ko te kaitahuri photovoltaic te nuinga o te wā e whakamahia ana hei huri i te iahiko tika i hangaia e ngā kōwae photovoltaic ki te iahiko tauutuutu. Ehara i te mea ko te mahi anake a te kaitahuri ko te hurihanga DC-AC, engari he mahi anō hoki hei whakanui ake i te mahi a te pūtau rā me te mahi hei tiaki hapa pūnaha. Kei raro nei he whakataki poto ki ngā mahi whakahaere aunoa me te whakaweto o te kaitahuri photovoltaic me te mahi whakahaere aroturuki mana mōrahi.
1. Mahi whakahaere aroturuki mana mōrahi
Ka rerekē te putanga o te waeine pūtau rā i runga i te kaha o te hihi o te rā me te pāmahana o te waeine pūtau rā tonu (te pāmahana maramara). Hei tāpiri, nā te mea he āhuatanga tō te waeine pūtau rā, arā, ka heke te ngaohiko i te pikinga o te iahiko, he wāhi mahi tino pai kei reira ka taea te whiwhi i te mana mōrahi. Kei te huri te kaha o te hihi o te rā, ā, he mārama kei te huri hoki te wāhi mahi tino pai. E pā ana ki ēnei huringa, kei te wāhi mahi tonu te waeine pūtau rā i te pūwāhi mana mōrahi, ā, ka whiwhi tonu te pūnaha i te putanga mana mōrahi mai i te waeine pūtau rā. Ko tēnei mana whakahaere ko te mana aroturuki mana mōrahi. Ko te āhuatanga nui o ngā kaitahuri mō ngā pūnaha mana rā ko te whakauru i te mahi aroturuki pūwāhi mana mōrahi (MPPT).
2. Mahi aunoa me te mahi aukati
I muri i te whitinga o te rā i te ata, ka piki haere te kaha o te hihi o te rā, ā, ka piki ake hoki te putanga o te pūtau rā. Ina tae ki te mana putanga e hiahiatia ana e te inverter, ka tīmata aunoa te inverter ki te oma. I muri i te tīmatanga o te mahi, ka aroturukihia tonutia e te inverter te putanga o te waeine pūtau rā. Mena he nui ake te mana putanga o te waeine pūtau rā i te mana putanga e hiahiatia ana kia mahi te inverter, ka haere tonu te inverter ki te oma; ka mutu tae noa ki te torengitanga o te rā, ahakoa he kapua, he ua. Ka taea hoki e te inverter te mahi. Ina iti haere te putanga o te waeine pūtau rā, ā, ka tata te putanga o te inverter ki te 0, ka hanga e te inverter he āhua tūtatari.
Haunga ngā mahi e rua kua whakaahuatia i runga ake nei, kei te inverter photovoltaic anō hoki te mahi hei ārai i te mahi motuhake (mō te pūnaha hono-pūnaha), te mahi whakatikatika ngaohiko aunoa (mō te pūnaha hono-pūnaha), te mahi kimi DC (mō te pūnaha hono-pūnaha), me te mahi kimi whenua DC (mō ngā pūnaha hono-pūnaha) me ētahi atu mahi. I roto i te pūnaha whakaputa hiko o te rā, ko te whai huatanga o te inverter he mea nui e whakatau ana i te kaha o te pūtau rā me te kaha o te pākahiko.
