Ko te whiriwhiri i tētahi BMS mō tētahi pūnaha rokiroki pūngao LiFePO4 ehara i te mea ngāwari pērā i te taurite i te mana inverter ki tētahi BMS 100A, 150A, 200A rānei.
Ko te iahiko BMS tika e whakawhirinaki ana ki te iahiko taha-pūhiko e hiahiatia ana e te inverter—ehara i te mea ko te mana o te inverter anake. Ko tētahi tukanga whiriwhiri whaihua ko:
Whakautu Tere: Kaua e Kōwhiri i te Iahiko BMS Mai i ngā Watts Inverter Anake
Tīmata ki te pepa raraunga mō te inverter. Tirohia ēnei tawhā e rima:
- Mana hohe tonu (W)
- Awhe ngaohiko whakahaere pākahiko/DC (V)
- Te aukume tukunga pākahiko mōrahi (A)
- Te aukume pākahiko mōrahi (A)
- Te kaha me te roa o te pikinga/ngaru
Iahiko pākahiko ≈ Mana kawenga AC ÷ (Ngaohiko pākahiko × Whai huatanga o te inverter)
Hei tauira, 5,000W ÷ 51.2V ≈ 97.7A. Engari he tātaitanga iahiko tino pai te 97.7A—ehara i te tohu e tika ana te whakamahi i tētahi BMS 100A.
5 Ngā Hipanga hei Whakatau i te Iahiko BMS
1Tirohia te Pepa Raraunga Inverter i te Tuatahi
Whakatuwheratia te pepa raraunga mō te tauira whakawhiti tika, ka kimi i ngā uara i raro nei.
| Tawhā | Ngā mea e hiahiatia ana e koe |
|---|---|
| Mana hohe tonu | Whakatauranga W tonu |
| Pūhiko/hiko DC | Awhe mahi e tika ana |
| Te aukume tukunga pākahiko mōrahi | A, mēnā kua tohua |
| Te aukume utu pākahiko mōrahi | A |
| Mana tihi/puku | W, te whakatauranga rānei a te kaihanga e tika ana |
| Te roa o te ngaru | Hekona/meneti, e ai ki te tohu |
Mena kua tohua kētia te iahiko tuku pākahiko mōrahi mō te āhua mahi e tika ana, whakamahia taua uara hei tāuru hoahoa matua. Ki te kore, haere tonu me te whakatau tata iahiko taha-pūhiko.
2Whakatauhia te Iahiko Taha-Pūhiko
Ina kore e wātea ngā raraunga tika mō te iahiko pākahiko, tīmata kiP = V × INō reira:
Mō te pākahiko LiFePO4 16S me te ngaohiko ingoa o 51.2V e tuku ana i te kawenga 5,000W:
5,000 ÷ 51.2 ≈ 97.7A
Mō tētahi whakatau tata pono ake, tāpirihia te whai huatanga o te inverter:
Mena ka whakamahia te whai huatanga 95% hei tauira anake:5,000 ÷ (51.2 × 0.95) ≈ 102.8AKaua e whakaaro ko te 95% mō ia kaitahuri hiko; whakamahia ngā raraunga e tika ana a te kaihanga i ngā wā katoa e wātea ana.
3Whakamahia te Ngaohiko Whakahaere Pūhiko e tika ana
I te mana kotahi,ko te iti o te ngaohiko pākahiko he nui ake te iahiko pākahiko.
| Ngaohiko Pūhiko Whakaahua | Iahiko i te 5,000W |
|---|---|
| 54V | 92.6A |
| 51.2V | 97.7A |
| 48V | 104.2A |
He tauira noa iho ēnei ngaohiko. Mō te hoahoa tuturu, whakamahia te ngaohiko whakahaere e tika ana mai i te pākahiko me ngā whakatakotoranga inverter. Kaua e ine i te hiahia o te iahiko mai i te ngaohiko ingoa anake.
4Tirohia motuhake te Ia Tonu me te Ia Pupuhi
Me aromatawai te BMS i runga i ngā whakaritenga whakahaere tonu me ngā tono wā poto e tika ana.
Auaha tonu
Manatokohia te iahiko pākahiko e hiahiatia ana i te wā e tukuna ana e te inverter te kawenga pumau e tumanakohia ana. Me tautoko te ara iahiko katoa—ngā pūtau, ngā pae pahi, ngā BMS, ngā taura, ngā hononga, ngā taputapu tiaki me te inverter—i tēnei whakaritenga.
Iahiko ngaru
Tērā pea ka hiahiatia he tīmatanga poto mō ngā motuka, ngā pūwero hiko, ngā papu me ngā kawenga rite.
Kāore i oti te whakatakotoranga o te ia tihi, engari kāore he roanga.
Whakatauritea te mana ngaru hurihuri + te roa → te iahiko ngaru taha-pūhiko e hiahiatia ana + te roa → te kaha wā-poto me te whanonga tiaki kua tuhia e te BMS → te kaha pūtau me te ara-iahiko.
5Tirohia te Iahiko Utu Motuhake
He rerekē ngā whakaritenga o te iahiko utu me te iahiko tuku. Whakatauhia te iahiko mōrahi ka taea e te inverter/riihi, te pūnaha utu rānei te tuku ki te pākahiko, kātahi ka whakataurite ki te kaha utu pūtau, te hoahoa kete, te kaha utu-iahiko BMS me ngā tikanga whakahaere e tika ana.
Te aukume tukunga tonu e hiahiatia ana: ___ A
Te au utu mōrahi: ___ A
Tauira Mahi: Pūhiko LiFePO4 16S 51.2V + Hurihuri 5kW
| Āhua | Tātaitanga | Iahiko Pūhiko |
|---|---|---|
| Pai rawa atu, kāore he ngaronga, 51.2V | 5,000 ÷ 51.2 | 97.7A |
| 95% te pai o te mahi, 51.2V | 5,000 ÷ (51.2 × 0.95) | 102.8A |
| 95% te pai o te mahi, 48V | 5,000 ÷ (48 × 0.95) | 109.6A |
Kāore e taea e te tātaitanga tuatahi 97.7A te whakaae i tētahi BMS 100A anake. Ko te kōwhiringa whakamutunga ka whakawhirinaki tonu ki ngā whakaritenga o te inverter, te hiahia ngaru, te ia utu, ngā pūtau, ngā tikanga whakatauranga BMS me te taiao whakahaere.
Me pēhea te aromatawai i tētahi BMS 100A, 150A, 200A rānei
| Akomanga o Nāianei | Aromatawai Tuatahi |
|---|---|
| 100A BMS | Kāore e taea te whakaae mā te tatau i te ngaohiko-ingoa anake. Tērā pea ka panaia te iahiko ki runga ake i te 100A e ngā mate me te ngaohiko whakahaere iti iho. |
| 150A BMS | Tērā pea ka noho tonu hei kaitono, engari me manatoko tonu te ia tonu tuturu, te ia ngaru, te ia utu, ngā whakatakotoranga BMS, ngā pūtau me te hoahoa mōkihi. |
| 200A BMS | Ka whakarato i te kaha iahiko teitei ake mēnā ka tautokona e te pūnaha katoa. Ehara i te mea ko te whakatauranga iahiko nui ake anake te mea tika. |

Ngā Pātai Auau
Q1He aha te rahi o te BMS e hiahiatia ana mō te inverter 5kW 48V?
Kāore he whakatauranga iahiko BMS whānui mō ia inverter 5kW 48V. Tirohia tuatahi te iahiko tuku pākahiko mōrahi o te inverter, mēnā kua tohua. Ki te kore, whakatauhia te iahiko taha-pūhiko mai i te mana hohe tonu, te ngaohiko pākahiko e tika ana me te whai huatanga o te inverter, kātahi ka manatoko i te ngaru, te iahiko utu, te kaha pūtau me ngā whakaritenga BMS.
Q2He rawaka te BMS 100A mō te inverter 5kW?
Kāore e taea te whakaū mai i te 5kW anake. Hei tauira, ko te 5,000W wehea ki te 51.2V he tata ki te 97.7A i mua i te whakaarohia o ngā mate o te inverter. Ka taea e te iahiko pākahiko te neke ake i te 100A ina whakaurua te whai huatanga me te ngaohiko whakahaere e tika ana.
Q3Ka whakatauhia e te pākahiko Ah te iahiko BMS?
Kāo. He rerekē ngā tawhā e whakaatu ana i te kaha o te pākahiko i roto i te Ah me te iahiko BMS i roto i te A. Mō tētahi pūnaha whakawhiti hiko, whakatauhia te iahiko pākahiko e hiahiatia ana mai i te mana o te pūnaha me ngā āhuatanga whakahaere, kātahi ka manatokohia ka taea e ngā pūtau me te BMS te tautoko.
Q4Ka pāngia te kōwhiringa BMS e te mana ngaru inverter?
Āe, mēnā e tika ana kia tukuna e te pūnaha pākahiko taua ngaru. Tirohia te rahi o te ngaru me tōna roa, kātahi ka whakataurite i te hiahia pākahiko ka puta mai me te kaha poto-wā o te BMS kua tuhia, te whanonga tiaki, ngā pūtau me te ara o nāianei.
Tonoa he Kōwhiringa BMS
Ko te whiriwhiri i waenga i te BMS 100A, 150A, 200A, teitei ake rānei te au me whakawhirinaki ki te pākahiko me ngā whakaritenga inverter tuturu - kaua ko te mana o te inverter anake.
Tukuna mai ngā mōhiohio kaupapa e wātea ana:
Te matū o te pākahiko + te tatau S + te kaha + te waitohu/tauira inverter + te mana tonu + te mana ngaru/te roa + te iahiko utu mōrahi + te rahinga i whakatauhia
