I-MPPT vs PWM: Yisiphi Isilawuli Sokushaja Selanga Okufanele Usikhethe?

Uma wakha noma ucacisa uhlelo lwelanga olungaphandle kwegridi, isilawuli sokushaja yingxenye enquma buthule ukuthi angakanani amandla ephaneli yakho afinyelela ibhethri. Ubuchwepheshe obubili obuvelele—i-PWM (i-Pulse Width Modulation) kanye ne-MPPT (i-Maximum Power Point Tracking)—bufana ephepheni lemininingwane kodwa buziphatha ngendlela ehlukile kakhulu ensimini. Lo mhlahlandlela uhlukanisa umehluko wangempela ukuze ukwazi ukukhetha ngokuzethemba.

Yini Eyenziwa Yisilawuli Sokushaja Ngempela?

Isilawuli sokushaja selanga sihlala phakathi kwamaphaneli akho e-PV kanye nebhange lakho lebhethri. Umsebenzi waso ukulawula i-voltage kanye nomsinga ukuze ibhethri lishaje ngokuphephile—ukuvimbela ukushaja ngokweqile, ukukhishwa okujulile, kanye nokubuyisela emuva umsinga ebusuku. Ngaphandle kwaso, ngisho nephaneli encane engu-100W ingalimaza ibhethri unomphela ezinsukwini ezimbalwa.

I-PWM: Elula, Efakazelwe, Engabizi Kakhulu

Izilawuli ze-PWM zisebenza njengeswishi ehlakaniphile. Zinciphisa kancane kancane ugesi njengoba ibhethri lisondela ekushajweni okugcwele, zibamba ugesi wephaneli eduze nogesi webhethri. Lokhu kusebenza kahle kuphela uma ugesi wephaneli ufana kakhulu nogesi webhethri (isibonelo, iphaneli engu-12V eshaja ibhethri engu-12V).

• Okuhle kakhulu: izinhlelo ezincane, isabelomali esincane, kanye nezimo lapho ama-voltage ephaneli nebhethri esevele evumelana khona.
• Izinketho ze-LDSOLAR: Iphupho Lomhlaba, Iphupho Lesibhakabhaka, kanye nochungechunge lwe-PWM lwe-Ocean Dream (10A–60A).
• Ukushintshana: lapho i-voltage yephaneli iphakeme kakhulu kune-voltage yebhethri, isilawuli se-PWM simane sichitha okungaphezulu njengokushisa.

I-MPPT: Ihlakaniphe Kakhulu, Isebenza Kakhulu, Iguquguquka Kakhulu

Isilawuli se-MPPT siqukethe i-converter ye-DC-DC ehlala ithola indawo yamandla ephezulu yephaneli bese iyinciphisa kunoma yini edingwa yibhethri. Amayunithi e-MPPT anamuhla, njengochungechunge lwe-LDSOLAR lwe-Tracer Dream, ngokuvamile asebenza kahle ngokuguqulwa okungu-95%–99%.

• Okuhle kakhulu: izinhlelo ezinkulu, izintambo zamaphaneli ane-voltage ephezulu, isimo sezulu esibandayo, kanye nesivuno esiphezulu.
• Izinketho ze-LDSOLAR: Uchungechunge lwe-Tracer Dream S / TU / F / 200V Pro, oluhlanganisa amandla angu-10A kuya ku-120A.

Umhlahlandlela Wezinqumo Ezisheshayo

• Isistimu ingaphansi kuka-~100W, ama-voltage afanayo, isabelomali esincane kakhulu → i-PWM
• Uhlelo lwe-200W+, amaphaneli aphezulu kagesi, noma ufuna isivuno esiphezulu → MPPT
• Izindawo ezibucayi kakhulu / ukukhanya kwelanga okubuthakathaka → i-MPPT (ukulandelela okusheshayo, isib. impendulo ye-LDSOLAR yamasekhondi angu-10-20)
