Momwe mungasankhire pakati pa PWM solar controller ndi MPPT solar controller

Solar controller ndi gawo lofunika kwambiri pakupanga mphamvu ya dzuwa. Olamulira a dzuwa amagwira ntchito yofunika kwambiri pakupanga mphamvu za dzuwa. Ntchito yayikulu ya chowongolera cha solar ndikuwunika mphamvu yamagetsi yomwe imatulutsa komanso momwe mphamvu yamagetsi yamagetsi imayendera ndikulipiritsa kapena kutulutsa batire ngati pakufunika.

Kuphatikiza apo, wowongolera solar amathanso kuyang'anira ndikuteteza batire kuti apewe ngozi monga kuchulukitsitsa, kutulutsa kwambiri, komanso kuzungulira kwafupi.

Owongolera dzuwa amagawidwa m'mitundu iwiri ya owongolera: PWM (Pulse Width Modulation) ndi MPPT (Maximum Power Point Tracking).

Kodi PWM solar controller ndi chiyani?

PWM solar controller ndi chipangizo chomwe chimagwiritsidwa ntchito kuwongolera kuyitanitsa kwa mapanelo adzuwa komanso kutulutsa mabatire. PWM imayimira Pulse Width Modulation, yomwe imayang'anira njira yolipiritsa posintha kuchuluka kwa mphamvu yamagetsi ndi kutulutsa kwapano ndi solar panel. Wowongolera solar wa PWM amawonetsetsa kuti solar panel imayendetsa batire moyenera ndikuteteza batire kuti isachuluke kapena kutulutsa. Nthawi zambiri imakhala ndi ntchito zosiyanasiyana zoteteza, monga chitetezo chamagetsi, chitetezo chafupipafupi komanso chitetezo cholumikizira, kuonetsetsa kuti dongosololi likuyenda bwino.

Ndi chiyaniMPPT wowongolera dzuwa?

Dzina lonse la MPPT solar controller ndi Maximum Power Point Tracking (Maximum Power Point Tracking) solar controller. Ndiwowongolera omwe amakulitsa mphamvu yamagetsi a solar. The MPPT solar controller imapangitsa kuti dzuwa liziyenda bwino potsata malo okwera kwambiri a solar panel mu nthawi yeniyeni, yomwe ndi malo abwino kwambiri ofananira pakati pa magetsi opangira magetsi ndi magetsi.

Owongolera dzuwa a MPPT amagwiritsa ntchito ma aligorivimu ndi zida zamagetsi kuti asinthe ma voltage ndi apano panthawi yolipiritsa batire kuti awonetsetse kuti ma solar amalipiritsa batire moyenera. Itha kusintha mphamvu ya batire yothamangitsa kuti igwirizane ndi kusintha kwa mphamvu ya solar panel, potero kumathandizira kagwiritsidwe ntchito ka mphamvu.

Owongolera dzuwa a MPPT nthawi zambiri amakhala ndi ntchito zingapo zoteteza, monga chitetezo chambiri, chitetezo chafupipafupi komanso chitetezo cholumikizira kumbuyo, kuonetsetsa kuti dongosololi likuyenda bwino. Ikhozanso kuyang'anira mphamvu zomwe zimachokera komanso momwe zimakhalira zolipiritsa ma sola ndi kupereka deta yoyenera ndi ziwerengero zothandizira ogwiritsa ntchito kuyendetsa bwino ndi kusamalira makina oyendera dzuwa.

Ndiye mungasankhe bwanji pakati pa PWM solar controller ndi MPPT solar controller?

Kaya ogwiritsira ntchito amasankha PWM olamulira dzuwa kapena MPPT olamulira dzuwa, ayenera kuganizira za moyo wawo, chilengedwe, mtengo ndi zina. Ndi njira iyi yokha yomwe angagwiritsidwe ntchito kwambiri. Ogwiritsa atha kuganizira izi:

1. Mphamvu yamagetsi yamagetsi a solar: Wowongolera PWM ndi woyenera pamagetsi otsika kwambiri a solar, nthawi zambiri 12V kapena 24V, pomwe wowongolera wa MPPT ndioyenera ma solar apamwamba kwambiri ndipo amatha kutengera mtundu wamagetsi ambiri.

2. Kuchita bwino kwadongosolo: Poyerekeza ndi olamulira a dzuwa a PWM, olamulira a MPPT ali ndi kusinthika kwakukulu ndipo amatha kupititsa patsogolo kugwiritsa ntchito mphamvu zamagetsi zamagetsi. M'makina akuluakulu a dzuwa, MPPT zowongolera dzuwa ndizofala kwambiri.

3. Mtengo: Poyerekeza ndi wolamulira wa MPPT, wolamulira wa PWM ali ndi mtengo wotsika. Ngati bajeti yanu ili yochepa ndipo dongosolo lanu la dzuwa ndi laling'ono, mukhoza kusankha woyang'anira PWM.

4. Malo oyika ma solar panels: Ngati ma solar panels aikidwa pamalo omwe kuwala kwa dzuwa kumakhala kosakhazikika kapena kusintha kwambiri, kapena pali zosiyana pakati pa mapanelo, wolamulira wa MPPT amatha kuthana ndi izi. Kuchulukitsa kugwiritsa ntchito mphamvu ya dzuwa.

Chidule:

Ngati muli ndi bajeti yochepa ndipo mukuyang'ana njira yotsika mtengo, yosavuta komanso yodalirika yokhala ndi kachitidwe kakang'ono ka mphamvu ya dzuwa, ndiye kuti mungasankhe PWM wolamulira dzuwa. Zowongolera dzuwa za PWM ndizokwera mtengo komanso zoyenerera kumagetsi ang'onoang'ono komanso apakatikati.

Ngati muli ndi bajeti yokwanira komanso dongosolo lalikulu, ndipo mukufuna kuchita bwino kwambiri komanso kuchita bwino, ndiye kuti musankhe MPPT wowongolera dzuwa. Owongolera dzuwa a MPPT ndi oyenera kupangira magetsi ang'onoang'ono, apakatikati komanso akulu. Ngakhale mtengo wake ndi wapamwamba kuposa owongolera dzuwa a PWM, ukhoza kupititsa patsogolo kusinthika kwadongosolo.
