He nui te pūnaha hiko o te rā 5kW mō te kāinga hei whakakaha i te whare toharite i Amerika. E whakamahi ana te whare toharite i te 10,000 kWh o te hiko ia tau. Hei whakaputa i taua nui o te hiko me te pūnaha 5kW, me tāuta e koe te 5000 watts o ngā panera hiko o te rā.
Ka rongoatia e te pākahiko lithium-ion 5kw te pūngao e whakaputaina ana e ō panera rā i te awatea kia taea ai e koe te whakamahi i te pō. He roa ake te ora o te pākahiko lithium-ion, ā, ka taea te whakahou i ngā wā maha atu i ētahi atu momo pākahiko.
He pai rawa te pūnaha hiko pūngao rā 5kw me te pākahiko mēnā kei te noho koe i tētahi rohe he nui te haumākū, he maha rānei ngā ua, nā te mea ka ārai i te wai kei uru ki roto i tō pūnaha, kei kino hoki. Ka whakarite hoki kia tiakina tō pūnaha mai i ngā whiunga uira me ētahi atu kino e pā ana ki te huarere pērā i ngā whatu, i ngā awhiowhio rānei, ka taea te whakangaro i ngā pūnaha waea tuku iho i roto i ngā meneti me te kore he tohu whakatūpato i mua.
Mena he pūnaha hiko rā 5kw tāu, e tumanakohia ana ka puta he hiko i waenga i te $0 me te $1000 ia rā.
Ko te nui o te hiko ka whakaputaina e koe ka whakawhirinaki ki te wāhi e noho ana koe, te nui o te rā e whiwhi ana tō pūnaha, me te mea he hotoke, kāore rānei. Hei tauira, ki te mea he hotoke, ka iti ake te hiko ka whakaputaina i tērā i te raumati—ka iti ake ngā hāora o te rā ka whiwhi koe, ka iti ake hoki te awatea.
Ka whakaputa te pūnaha pākahiko 5kw i te 4,800kwh ia rā.
Ka puta te hiko o te pūnaha rā 5kW me te pākahiko tārua i te 4,800 kWh ia tau. Ko te tikanga, ki te whakamahia e koe te nui katoa o te hiko e whakaputaina ana e tēnei pūnaha i ia rā, e whā tau te roa hei whakamahi i te hiko katoa e whakaputaina ana e koe.
