Ua ʻoi aku ka maikaʻi o ka pā uila o BSLBATT ma mua o nā ʻeke Acid Lead?

Ke lilo nei nā ʻōhua mālama home i mea hoʻohui kaulana loa i nā ʻōnaehana solar, me nā mea kemika maʻamau ʻelua ʻo ia nā pahu lead-acid a me ka lithium. E like me ka inoa i hōʻike ʻia, hana ʻia nā pā lithium-ion mai ka metala lithium, ʻoiai ʻo nā pākī lead-acid i hana mua ʻia mai ke kēpau a me ka waikawa. No ka mea, ua hoʻohana ʻia kā mākou pā mana i hoʻopaʻa ʻia i ka paia e ka lithium-ion, e hoʻohālikelike mākou i nā ʻelua - ka pā mana vs. lead acid.

1. Voltage & Uila:

Hāʻawi ka Lithium Powerwall i nā voltage nominal ʻokoʻa ʻē aʻe, ʻo ia ka mea i ʻoi aku ka kūpono ma ke ʻano he pani pani no nā pākika lead-acid.ʻO ka hoʻohālikelike uila ma waena o kēia mau ʻano ʻelua:

  • ʻO ka pākaukau Lead-acid:

12V*100Ah=1200WH

48V*100Ah=4800WH

  • Pākuʻi Lithium Powerwall:

12.8V*100Ah=1280KWH

51.2V*100Ah=5120WH

Hāʻawi ka Lithium Powerwall i ka hiki ke hoʻohana ʻia ma mua o kahi huahana i hoʻohālikelike ʻia i ka waikawa lead-acid. Hiki iā ʻoe ke manaʻolana a ʻoi aku ka nui o ka manawa holo.

2. Ke ola pōʻaiapuni.

Ua kamaʻāina paha ʻoe i ke ola pōʻaiapuni o ka pākaukau lead-acid.No laila e haʻi wale aku mākou iā ʻoe i ke ola pōʻaiapuni o kā mākou pā i kau ʻia i ka pā LiFePO4.

Hiki iā ia ke hōʻea ma mua o 4000 mau pōʻaiapuni @100%DOD, 6000 mau pōʻaiapuni @80% DOD. I kēia manawa, hiki ke hoʻokuʻu ʻia nā pākahi LiFePO4 a hiki i 100% me ka ʻole o ka pōʻino. E hōʻoia ʻoe e hoʻopiʻi koke i kāu pākaukau ma hope o ka hoʻokuʻu ʻana, ʻōlelo mākou e kaupalena ʻia ka hoʻokuʻu ʻana i ka 80-90% hohonu o ka hoʻokuʻu ʻana (DOD) e pale aku i ka BMS e wehe i ka pila.

3. Palapala Hoʻopaʻa Powerwall Versus Lead-Acid

Ke nānā pono nei ka BMS Powerwall o BSLBATT Powerwall i ka nui o ka uku, hoʻokuʻu, nā pae uila, ka mahana, ka pākēneka o ka honua i lanakila, a pēlā aku, i mea e hoʻonui ai i ko lākou ola e hiki ai ke hele mai me kahi palapala hōʻoia 10-makahiki me 15- 20 makahiki o ke ola lawelawe.

I kēia manawa, ʻaʻohe mana o ka poʻe hana i nā pākī lead-acid i ke ʻano o ka hoʻohana ʻana i kā lākou huahana a no laila hāʻawi wale i nā palapala hōʻoia no hoʻokahi makahiki a ʻelua paha inā makemake ʻoe e uku no kahi brand ʻoi aku ka pipiʻi.

ʻO kēia ka lanakila nui o ka BSLBATT Powerwall ma luna o ka hoʻokūkū. ʻO ka hapa nui o ka poʻe, a me ka poʻe ʻoihana, ʻaʻole makemake lākou e hoʻopuka i kahi kālā nui no kahi hoʻopukapuka hou ke ʻole hiki iā lākou ke pakele me ka uku ʻole ʻana no nā pilikia ma hope o ka mākeke ma ke kumu mau. ʻO ka Lithium Powerwall ke kumu kūʻai kūʻai kiʻekiʻe loa, akā ʻo kona lōʻihi a me ka palapala hōʻoia 10 makahiki i hāʻawi ʻia e ka mea hoʻolako e hōʻemi loa i kāna kumukūʻai hoʻohana lōʻihi.

4. Ka wela.

Hiki i ka LiFePO4 Lithium Iron Phosphate ke kū i kahi ākea ākea o ka wela i ka wā e hoʻokuʻu ana, no laila hiki ke hoʻohana ʻia i ka hapa nui o nā wahi wela.

  • ʻO ka Mahana Kūlohelohe no ka pākaukau Lead Acid: –4°F a 122°F
  • ʻO ka mahana wela no ka pā uila uila LiFePO4: –4°F a hiki i 140°F Eia kekahi, me ka hiki ke hoʻomanawanui i nā wela kiʻekiʻe, hiki ke noho palekana ma mua o ka pākaukau lead-acid no ka mea ua hoʻolako ʻia nā pā LiFePO4 me BMS. Hiki i kēia ʻōnaehana ke ʻike i ka ʻike ʻana i ka mahana ʻokoʻa i ka manawa a pale i ka pākaukau, hoʻopau koke i ka hoʻouka ʻana a i ʻole ka hoʻokuʻu koke ʻana, no laila ʻaʻohe wela i hana ʻia.

5. Ka hiki ke waiho i ka Powerwall me ka Lead-Acid

ʻAʻole hiki ke hoʻohālikelike pololei i ka mana o ka Powerwall a me nā pākaʻi lead-acid no ka mea ʻaʻole like ko lākou ola lawelawe. Eia nō naʻe, ma muli o ka ʻokoʻa o DOD (Depth of Discharge), hiki iā mākou ke hoʻoholo i ka hiki ke hoʻohana ʻia o kahi pākaukau Powerwall o ka mana like ʻoi aku ka ʻoi aku o ka nui o ka pākaukau lead-acid.

No ka laʻana: manaʻo i ka hiki o10kWh Powerwall mau pihia me na pilaki-akika kepau; no ka mea, ʻaʻole hiki ke ʻoi aku ka hohonu o ka hoʻokuʻu ʻana o nā pākini lead-acid ma mua o 80%, ʻoi aku ka maikaʻi o 60%, no laila, ʻo ka ʻoiaʻiʻo wale nō lākou ma kahi o 6kWh - 8 kWh o ka hiki ke mālama pono. Inā makemake wau iā lākou e mau i 15 mau makahiki, a laila pono wau e pale i ka hoʻokuʻu ʻana iā lākou ma mua o 25% i kēlā me kēia pō, no laila ʻo ka hapa nui o ka manawa aia lākou ma kahi o 2.5 kWh o ka mālama. Hiki ke hoʻokuʻu loa ʻia nā ʻona LiFePO4 Powerwall i 90% a i ʻole 100%, no laila, no ka hoʻohana ʻana i kēlā me kēia lā, ʻoi aku ka maikaʻi o ka Powerwall, a hiki ke hoʻokuʻu ʻia nā pā LiFePO4 i ka hohonu ke pono e hāʻawi i ka mana i ka wā ʻino a / a i ʻole i nā wā o ka hoʻohana mana kiʻekiʻe.

6. Kumukuai

E ʻoi aku ka kiʻekiʻe o ke kumu kūʻai o ka pākaukau LiFePO4 ma mua o nā pākī lead-acid o kēia manawa, pono e hoʻolilo hou i ka wā mua. Akā e ʻike ʻoe ʻoi aku ka maikaʻi o ka pākaukau LiFePO4. Hiki iā mākou ke kaʻana like i ka papa hoʻohālikelike no kāu kuhikuhi inā ʻoe e hoʻouna i ka kikoʻī a me ke kumukūʻai o kāu mau pākaukau i hoʻohana ʻia. Ma hope o ka nānā ʻana i ke kumukūʻai Unit no kēlā me kēia lā (USD) no 2 mau ʻano pākahi. E ʻike ʻoe e ʻoi aku ka liʻiliʻi o ke kumu kūʻai / pōʻaiapuni o nā ʻāpana ʻokoʻa LiFePO4 ma mua o nā pākiʻi lead-acid.

7. Ka hopena i ke kaiapuni

Ke hopohopo nei mākou a pau e pili ana i ka pale ʻana i ke kaiapuni, a ke hoʻoikaika nei mākou e hana i kā mākou ʻāpana e hōʻemi i ka haumia a me ka hoʻohana waiwai. I ke koho ʻana i kahi ʻenehana pākaukau, he koho maikaʻi loa nā pila LiFePO4 no ka hiki ʻana i ka ikehu hou e like me ka makani a me ka lā a no ka hōʻemi ʻana i nā hopena o ka ʻili waiwai.

8. Powerwall Efficiency

ʻO 95% ka ʻoi aku ka maikaʻi o ka mālama ʻana i ka ikehu o Powerwall, ʻoi aku ka maikaʻi ma mua o nā pākī lead-acid ma kahi o 85%. I ka hoʻomaʻamaʻa, ʻaʻole kēia he ʻokoʻa nui, akā kōkua ia. Ma kahi o hoʻokahi hapalua a ʻelua hapakolu o ka kilowatt-hour emi iho ka uila o ka lā e hoʻopiha piha ai i kahi Powerwall me 7kWh ma mua o nā ʻakika lead-acid, ʻo ia hoʻi ka hapalua o ka awelika o kēlā me kēia lā o ka panel solar.

9. Ho'olalewa

He kūpono ka Powerwall no ka hoʻokomo ʻana i loko a i waho paha, lawe i kahi wahi liʻiliʻi loa, a e like me ka inoa i ʻōlelo ʻia e kau ʻia ma nā paia. Ke hoʻokomo pono ʻia e palekana loa.

Aia kekahi mau ʻakika lead-acid i hiki ke hoʻokomo ʻia i loko o ka hale me ka mālama pono ʻana, akā ma muli o ka liʻiliʻi loa akā ʻo ka manawa maoli e hoʻoholo ai kahi pākī lead-acid e hoʻololi iā ia iho i puʻu wela o ka fuming goo, paipai ikaika wau e waiho i waho.

ʻAʻole i like ka nui o ka nui o nā wahi i lawe ʻia e ka nui o nā pākaʻi lead-acid no ka hoʻoulu ʻana i kahi hale waho-grid e like me ka nui o ka poʻe e manaʻo pinepine ai akā ʻoi aku ka nui ma mua o ka mea e koi ai nā Powerwalls.

No ka lawe ʻana i kahi ʻaoʻao ʻelua kanaka i waho, pono paha e koi ʻia kahi panakō o nā ʻeke waikona a puni ka laula o kahi moena hoʻokahi, ka mānoanoa o ka pā ʻaina, a e like paha ke kiʻekiʻe e like me ka pahu hau pahu. ʻOiai ʻaʻole pono pono ka pā pākaukau no nā mea hoʻokomo āpau, pono e mālama ʻia i mea e pale ai i nā keiki mai ke koʻikoʻi e hoʻāʻo i ka ʻōnaehana a i ʻole.

10. Ka malama ana

Pono ka mālama ʻia ʻana o nā ʻakika lead-acid lōʻihi i hoʻopaʻa ʻia i kēlā me kēia ʻeono mahina. ʻAʻole pono ka Powerwall.

Inā makemake ʻoe i kahi pākaukau me ka 6000 cycles e pili ana i 80% DOD; Inā makemake ʻoe e hoʻopaʻa i ka pākaukau i loko o 1-2 mau hola; Inā makemake ʻoe i ka hapalua o ke kaumaha a me ka hoʻohana ʻana i ka lewa o ka pākaukau lead-acid… E hele mai a hele pū me ke koho pā uila LiFePO4. Manaʻo mākou i ka hele ʻana i ka ʻōmaʻomaʻo, e like me ʻoe.
