Kākoʻo i ka nānā mamao ʻana o ka polokalamu/pc 20A 30A 40A 50A 60A mppt solar charge controller

1. No ke aha i ʻoi aku ai ke kiʻekiʻe o kāu ʻōlelo ma mua o nā mea hoʻolako ʻē aʻe?

Ma ka mākeke Kina, nui nā hale hana e kūʻai aku ana i nā inverters haʻahaʻa ke kumukūʻai i hoʻākoakoa ʻia e nā hale hana liʻiliʻi, laikini ʻole ʻia. Hoʻemi kēia mau hale hana i nā kumukūʻai ma ka hoʻohana ʻana i nā ʻāpana haʻahaʻa. ʻO ka hopena kēia i nā pilikia palekana nui.

He ʻoihana ʻoihana ʻo SOLARWAY e komo ana i ka R&D, ka hana ʻana, a me ke kūʻai aku ʻana i nā inverters mana. Ua komo ikaika mākou i ka mākeke Kelemania no nā makahiki he 10 a ʻoi, e hoʻokuʻu aku ana ma kahi o 50,000 a 100,000 mau inverters mana i kēlā me kēia makahiki i Kelemania a me nā mākeke kokoke. Pono ka maikaʻi o kā mākou huahana i kou hilinaʻi!

2. Ehia mau māhele o kāu mau mea hoʻololi mana e like me ke ʻano o ka nalu hoʻopuka?

ʻAno 1: Hoʻohana kā mākou mau mea hoʻololi Sine Wave Modified NM a me NS i ka PWM (Pulse Width Modulation) e hana i kahi nalu sine i hoʻololi ʻia. Mahalo i ka hoʻohana ʻana i nā kaapuni akamai, hoʻolaʻa ʻia a me nā transistors hopena kahua kiʻekiʻe, hōʻemi nui kēia mau mea hoʻololi i ka nalowale o ka mana a hoʻomaikaʻi i ka hana hoʻomaka palupalu, e hōʻoiaʻiʻo ana i ka hilinaʻi nui aʻe. ʻOiai hiki i kēia ʻano mea hoʻololi mana ke hoʻokō i nā pono o ka hapa nui o nā lako uila ke ʻole koi nui ka maikaʻi o ka mana, ʻike mau ia ma kahi o 20% harmonic distortion i ka wā e holo ana i nā lako paʻakikī. Hiki i ka mea hoʻololi mana ke hana i ka hoʻopilikia alapine kiʻekiʻe i nā lako kamaʻilio lekiō. Eia nō naʻe, he pono kēia ʻano mea hoʻololi mana, hana i ka walaʻau haʻahaʻa, kūpono ke kumukūʻai, a no laila he huahana nui ia ma ka mākeke.

ʻAno 2: Hoʻohana kā mākou mau mea hoʻololi mana Sine Wave NP, FS, a me NK series i kahi hoʻolālā kaapuni hoʻopili kaʻawale, e hāʻawi ana i ka pono kiʻekiʻe a me nā ʻano nalu hoʻopuka paʻa. Me ka ʻenehana alapine kiʻekiʻe, ua liʻiliʻi kēia mau mea hoʻololi mana a kūpono no nā ʻano ukana like ʻole. Hiki ke hoʻopili ʻia lākou i nā mea uila maʻamau a me nā ukana inductive (e like me nā pahu hau a me nā wili uila) me ka ʻole o ka hoʻopilikia ʻana (e laʻa, ke kani ʻana a i ʻole ka walaʻau TV). ʻO ka hopena o kahi mea hoʻololi mana nalu sine maʻemaʻe ua like ia me ka mana grid a mākou e hoʻohana ai i kēlā me kēia lā - a ʻoi aku paha ka maikaʻi - ʻoiai ʻaʻole ia e hana i ka haumia electromagnetic e pili ana me ka mana grid-tied.

3. He aha nā mīkini ukana resistive?

ʻO nā mea hana e like me nā kelepona paʻalima, nā kamepiula, nā TV LCD, nā kukui incandescent, nā peʻahi uila, nā mea hoʻolaha wikiō, nā mīkini paʻi liʻiliʻi, nā mīkini mahjong uila, a me nā mea kuke laiki ua manaʻo ʻia he mau ukana resistive. Hiki i kā mākou mau inverters nalu sine i hoʻololi ʻia ke hoʻoikaika pono i kēia mau mea hana.

4. He aha nā mīkini ukana inductive?

ʻO nā mīkini ukana inductive he mau mea hana e hilinaʻi nei i ka hoʻokomo electromagnetic, e like me nā motika, nā compressors, nā relays, nā kukui fluorescent, nā kapuahi uila, nā pahu hau, nā ea hoʻoluʻu, nā kukui mālama ikehu, a me nā pamu. ʻO ka maʻamau, pono kēia mau mīkini i 3 a 7 mau manawa o ko lākou mana i helu ʻia i ka wā hoʻomaka. ʻO ka hopena, ʻo ka inverter nalu sine maʻemaʻe wale nō ke kūpono no ka hoʻoikaika ʻana iā lākou.

5. Pehea e koho ai i kahi inverter kūpono?

Inā loaʻa i kāu ukana nā mea hana resistive, e like me nā kukui uila, hiki iā ʻoe ke koho i kahi inverter nalu sine i hoʻololi ʻia. Eia nō naʻe, no nā ukana inductive a me capacitive, paipai mākou e hoʻohana i kahi inverter nalu sine maʻemaʻe. ʻO nā hiʻohiʻona o ia mau ukana e komo pū me nā peʻahi, nā mea hana pololei, nā ea hoʻoluʻu, nā pahu hau, nā mīkini kope, a me nā kamepiula. ʻOiai hiki i kahi inverter nalu sine i hoʻololi ʻia ke hoʻomaka i kekahi mau ukana inductive, hiki iā ia ke hoʻopōkole i kona ola no ka mea pono nā ukana inductive a me capacitive i ka mana kiʻekiʻe no ka hana maikaʻi loa.

6. Pehea e koho ai au i ka nui o ka inverter?

Pono nā ʻano ukana like ʻole i ka nui o ka mana. No ka hoʻoholo ʻana i ka nui o ka inverter, pono ʻoe e nānā i nā helu mana o kāu mau ukana.

• Nā ukana resistive: E koho i kahi inverter me ka helu mana like me ka ukana.
• Nā ukana capacitive: E koho i kahi inverter me 2 a 5 mau manawa ka helu mana o ka ukana.
• Nā ukana inductive: E koho i kahi inverter me 4 a 7 mau manawa o ka helu mana o ka ukana.

7. Pehea e hoʻopili ʻia ai ka pila a me ka inverter?

Manaʻo nui ʻia e pōkole loa nā kaula e hoʻopili ana i nā kikowaena pila i ka inverter. No nā kaula maʻamau, ʻaʻole pono e ʻoi aku ka lōʻihi ma mua o 0.5 mika, a pono e kūlike ka polarity ma waena o ka pila a me ka inverter.

Inā pono ʻoe e hoʻonui i ka mamao ma waena o ka pila a me ka inverter, e ʻoluʻolu e kelepona mai iā mākou no ke kōkua. Hiki iā mākou ke helu i ka nui a me ka lōʻihi o ke kaula kūpono.

E hoʻomanaʻo e hiki i nā pilina kaula lōʻihi ke hoʻoulu i ka pohō voltage, ʻo ia hoʻi, ʻoi aku ka haʻahaʻa o ka voltage inverter ma mua o ka voltage terminal pila, e alakaʻi ana i kahi alarm undervoltage ma ka inverter.

8.Pehea ʻoe e helu ai i ka ukana a me nā hola hana e pono ai e hoʻonohonoho i ka nui o ka pākaukau?

Hoʻohana pinepine mākou i ke ʻano hana ma lalo nei no ka helu ʻana, ʻoiai ʻaʻole paha he 100% pololei ma muli o nā kumu e like me ke kūlana o ka pila. Loaʻa paha i nā pila kahiko kekahi pohō, no laila pono e manaʻo ʻia kēia he waiwai kuhikuhi:

Nā hola hana （H） = (Ka mana o ka pila （AH）*Volika pila （V0.8）/ Mana ukana （W）
