Yadda Ake Zaba Madaidaicin Mai Kula da Solar MPPT don Tsarin ku

A duniyar makamashin hasken rana, mai sarrafawa yana aiki kamar yadda “ƙwaƙwalwa” na tsarin ku. Zaɓi tsakanin a PWM kuma an Mppt mai sarrafawa, da daidaita shi daidai da bankin baturin ku, na iya zama bambanci tsakanin tsarin aiki mai girma da wanda ya gaza da wuri.

Ga duk abin da kuke buƙatar sani don yin zaɓi mai kyau.

1. PWM vs. Mppt: Menene Bambancin Gaskiya?

Don zaɓar daidai, dole ne ka fara fahimtar yadda waɗannan fasahohin biyu ke sarrafa makamashi.

PWM (Julse Nisa Modulation)

Yi tunanin PWM azaman a “Daidaitaccen Sauyawa.” Yana aiki azaman haɗin kai kai tsaye tsakanin rukunan hasken rana da baturi.

• Yadda yake aiki: Lokacin da baturi ya kusa cika, da sauri “kyalkyali” kunnawa da kashewa don kula da wutar lantarki.

• The Downside: Ba zai iya daidaita ƙarfin lantarki don ƙara halin yanzu ba. Idan panel ɗinku 18V kuma baturin ku shine 12V, karin 6V kawai a banza ne.

• Mafi kyau ga: Ƙanƙane, sauki tsarin (E.g., rike baturi daya a rumfa) inda kasafin kudi shine fifiko.

Mppt (Matsakaicin Binciken Wutar Wuta)

Yi tunanin MPPT azaman a “Smart Transformer.” Yana da mahimmanci mafi ci gaba da inganci.

• Yadda yake aiki: Yana sa ido akai-akai akan fitowar panel kuma yana ƙididdigewa “Matsakaicin Wutar Wuta.” Yana ɗaukar wuce gona da iri na ƙarfin lantarki daga bangarorin kuma ya canza shi zuwa karin halin yanzu don baturi.

• Amfanin: Yana da 25%-30% mafi inganci fiye da PWM, musamman a yanayin sanyi ko gajimare.

• Mafi kyau ga: Saitunan sana'a, RVs, gidajen kashe-kashe, da kowane tsarin amfani da manyan hasken rana.

2. Dokar Zinariya: Yadda Ake Girman MPPT ɗinku

Lokacin zabar MPPT, dole ne ku dubi kwatance biyu: Sama (zuwa hasken rana) da Kasa (zuwa baturin ku).

A. Duba sama: Wutar Lantarki na Solar (Voc)

Hanyar da ta fi dacewa don lalata MPPT ita ce ta wuce gona da iri Matsakaicin Input Voltage.

• Duba cikin Voc (Buɗe Wutar Lantarki) a bayan fa'idodin hasken rana.

• Idan kun haɗa panels a ciki Jerin, karfin wutar lantarkin su yana kara girma.

• Mulki: Dole ne jimlar wutar lantarki ta jeri ta zama aƙalla 15% ƙasa da ƙayyadaddun ƙimar MPPT don lissafin yanayin sanyi (wanda ke sa wutar lantarki ta karu).

B. Kalli Kasa: Cajin Yanzu (Amsoshi)

Babban darajar MPPT (E.g., 40A, 60A) yana nufin nawa halin yanzu zai iya aikawa zuwa baturi.

• Formula: $Jimlar Solar Watts div Baturi Voltage = Amps$ da ake bukata.

• Misali: Idan kana da 800W na bangarori da baturi 12V: $800W div 12V = 66.6A$. Kuna buƙatar a 80Bayanin MPPT.

3. Mahimman Factor: Daidaiton Baturi

Mai sarrafawa yana da kyau kawai kamar dacewarsa tare da batura.

Daidaita iyawa (Ah)

Kada ku haɗa ƙaramin MPPT tare da babban bankin baturi, ko akasin haka.

• Manyan Batura (E.g., 600Ah +): Ana buƙatar manyan MPPTs na yanzu (60A-100A). Idan halin yanzu yayi ƙasa da ƙasa, baturin bazai taɓa samun cikakken caji ba yayin ƙayyadaddun sa'o'in hasken rana.

Daidaiton Chemistry (Da “BMS” Mulki)

Ana amfani da tsarin zamani sau da yawa LiFePO4 (Lithium) batura.

• Gargadi: Tabbatar cewa MPPT ɗin ku yana da sadaukarwa “Lithium” yanayin. Batura lithium suna da takamaiman bayanan caji. Amfani da ma'auni “Jagorar acid” saitin na iya lalata Tsarin Gudanar da Baturi (BMS) ko sel.

Guji “Hadawa” Baturi

Ɗayan kuskuren da aka fi sani shine haɗa batura masu iya aiki daban-daban (E.g., 200Ah da 600Ah) zuwa MPPT iri ɗaya.

• Hadarin: Ƙarfi daban-daban yana nufin juriya na ciki daban-daban. Lokacin amfani mai nauyi, ƙaramin baturin zai yi aiki da yawa, haifar da BMS tayi tafiya ko baturin yayi zafi sosai.

• Magani: Yi amfani da batura koyaushe iri iri, shekaru, da iya aiki a banki guda.

Takaitawa Lissafin Takaddama don Masu Siyayya

Kafin ka saya, tabbatar da wadannan abubuwa guda hudu:

1. inganci: Shin jimlar wutar lantarki da aka raba ta hanyar ƙarfin baturi ya dace da ƙimar Amp na MPPT?

2. Tsaro: Shin jimillar Voc ɗin array ɗin hasken rana yana tsayawa lafiya ƙasa da max ɗin ƙarfin shigarwar MPPT?

3. Nau'in Baturi: Shin mai sarrafawa yana goyan bayan takamaiman sinadarai na baturi (gubar-acid, Gel, ya da lithium)?

4. Tabbatar da gaba: Idan kuna shirin ƙara ƙarin bangarori daga baya, saya MPPT tare da ƙimar Amp mafi girma yanzu don adana kuɗi a cikin dogon lokaci.

Zaɓin MPPT mai inganci jari ne. Duk da yake yana tsada sama da PWM, Ƙarfafa ingantaccen aiki da kariyar baturi zai biya kansa a cikin shekarar farko na amfani.
