1. Hoʻohui maikaʻi ʻia ka mana o ka ikehu hou e like me ka mana makani a me ka mana photovoltaic i ka pā.ʻO ka randomness inherent, intermittency a me ka volatility o ka hoʻokumu ʻana i ka makani makani e hoʻoholo ai i kona hoʻomohala nui ʻana e loaʻa i kahi hopena koʻikoʻi i ka hana palekana o ka ʻōnaehana mana.Me ka hoʻomohala wikiwiki ʻana o ka ʻoihana makani makani, ʻoi aku ka nui o nā mahiʻai makani ma koʻu ʻāina ʻo "ka hoʻomohala kikowaena nui a me ka hoʻouna ʻana i kahi lōʻihi", ʻo ka hoʻokumu ʻana i ka mana o nā māla makani nui i nā pilikia koʻikoʻi i ka ka hana a me ka hoomalu ana i ka mana nui.
Hoʻopili ʻia ka mana kiʻi kiʻi kiʻi kiʻi e ka wela ambient, ka ikaika o ka mālamalama o ka lā a me ke ʻano o ka wā, a ʻo ka hana mana photovoltaic e hōʻike ana i nā ʻano o ka fluctuations random.Ke hōʻike nei koʻu ʻāina i kahi ʻano hoʻomohala o ka "decentralized development, low-voltage on-site access" a me "nui-scale development, medium and high voltage access", e hoʻopuka ana i nā koi kiʻekiʻe no ka hoʻoponopono kiʻekiʻe o ka mana a me ka hana palekana o nā ʻōnaehana mana.
No laila, ua lilo nā huahana mālama ikehu nui i mea koʻikoʻi i ka hoʻoponopono ʻana i ka kuee ma waena o ka mākia a me ka hoʻoulu ʻana i ka ikehu hou.ʻO ka lithium iron phosphate battery energy storage system nā hiʻohiʻona o ka hoʻololi wikiwiki ʻana i nā kūlana hana, ke ʻano hana maʻalahi, kiʻekiʻe kiʻekiʻe, palekana a me ka mālama ʻana i ke kaiapuni, a me ka scalability ikaika.ʻO ka pilikia kaohi uila kūloko, hoʻomaikaʻi i ka hilinaʻi o ka mana o ka mana hou a hoʻomaikaʻi i ka maikaʻi o ka mana, i hiki ai i ka ikehu hou ke lilo i mea hoʻomau a paʻa.
Me ka hoʻonui mau ʻana o ka hiki a me ka unahi, a me ka ulu mau ʻana o ka ʻenehana hoʻohui, e hoʻemi hou ʻia ke kumukūʻai o nā ʻōnaehana mālama ikehu.Ma hope o nā ho'āʻo palekana a me ka hilinaʻi lōʻihi, manaʻo ʻia e hoʻohana ʻia nā ʻōnaehana mālama uila lithium iron phosphate i ka ikehu hou e like me ka makani makani a me ka mana photovoltaic.Ua hoʻohana nui ʻia i loko o ka pilina pūnaewele palekana o ka hoʻomohala ʻana i ka ikehu a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka mana.
2 mana hoʻoponopono kiʻekiʻe.ʻO ke ʻano nui o ka hoʻoponopono kiʻekiʻe kiʻekiʻe o ka mana i hoʻopaʻa mau ʻia i nā kikowaena mālama mālama.No ka mea, pono e kūkulu ʻia nā waihona ʻelua ʻelua, ʻo ka lua o luna a me lalo, kahi i kaupalena ʻia e nā kūlana ʻāina, ʻaʻole maʻalahi ke kūkulu ʻana ma ka pāpū, a he nui ka wahi a he kiʻekiʻe ke kumukūʻai mālama.ʻO ka hoʻohana ʻana i ka ʻōnaehana hoʻopaʻa ʻana i ka ʻenehana lithium iron phosphate pākaukau e hoʻololi i ka hale mana mālama ʻana i ka pumped, e hoʻokō i ka haʻahaʻa kiʻekiʻe o ka mana mana, ʻaʻole i kaupalena ʻia e nā kūlana geographical, koho kahua manuahi, liʻiliʻi ka hoʻopukapuka ʻana, liʻiliʻi ka noho ʻana o ka ʻāina, haʻahaʻa ka uku mālama. e pāʻani i ka hana koʻikoʻi i ke kaʻina o ka hoʻoponopono kiʻekiʻe o ka mana.
3 Māhele mana mana.Ma muli o nā hemahema o ka mana mana nui pono'ī, paʻakikī ke hōʻoia i ka maikaʻi, ka pono, ka palekana a me ka pono o ka lako mana.No nā ʻāpana koʻikoʻi a me nā ʻoihana, pono pinepine nā lako mana ʻelua a i ʻole nā ​​​​mana he nui e like me ke kākoʻo a me ka pale.Hiki i ka lithium iron phosphate battery storage system ke hōʻemi a pale aku paha i ka pau ʻana o ka mana ma muli o ka hāʻule ʻana o ka mana mana a me nā hanana like ʻole i manaʻo ʻole ʻia, a e hōʻoia i ka palekana a me ka hilinaʻi o ka mana i nā halemai, nā panakō, nā kauoha a me nā kikowaena mana, nā kikowaena hoʻoili ʻikepili, nā ʻoihana mea kemika a me ka pololei. ʻoihana hana.E pāʻani i kahi kūlana koʻikoʻi.
4 UPS lako mana.ʻO ka hoʻomau a me ka wikiwiki o ka hoʻokele waiwai o Kina ua alakaʻi i ka decentralization o nā pono o nā mea hoʻohana i ka mana o ka UPS, kahi i hoʻonui ai i nā ʻoihana a me nā ʻoihana e loaʻa mau ka noi no ka lako mana UPS.
Ke hoʻohālikelike ʻia me nā pākaʻi lead-acid, ʻoi aku ka maikaʻi o nā pākahi lithium iron phosphate i ke ola pōʻai lōʻihi, ka palekana a me ke kūpaʻa, ka pale ʻana i ke kaiapuni, a me ka haʻahaʻa haʻahaʻa haʻahaʻa.e hoʻohana nui ʻia.
