Indlela Yokulinganisa Isilawuli Sokushaja se-MPPT Sesistimu Yakho Engaphandle Kwegridi

Ukulinganisa isilawuli sokushaja akuyona into yokuqagela—kuyisibalo esilula. Uma ungenzi kahle bese uchitha imali kuyunithi enkulu kakhulu noma, okubi nakakhulu, upheke isilawuli esincane kakhulu. Nansi indlela eqondile esiyisebenzisayo lapho sisiza abahlanganisi ukucacisa amayunithi e-LDSOLAR MPPT.

Ifomula Eyinhloko

Isilawuli Esiphezulu Samandla (A) ≥ (I-Array Wattage ÷ I-Battery Voltage) × isici sokuphepha esingu-1.25. Isici esingu-1.25 simboza ukukhanya okungaphezulu komhlaba wangempela kanye nokulahlekelwa kwezintambo.

Isibonelo Esisebenzayo 1: Uhlelo lwe-12V

• I-Array = 400W, Ibhethri = 12V
• 400W ÷ 12V = 33.3A → 33.3A × 1.25 = 41.6A
• → Khetha i-45A–60A MPPT (isib. iTracer Dream S 50A).

Isibonelo Esisebenzayo 2: Uhlelo lwe-48V

• I-Array = 2,000W, Ibhethri = 48V
• 2,000W ÷ 48V = 41.7A → 41.7A × 1.25 = 52A
• → I-MPPT engu-60A ifanelana; ukuze uthole i-headroom khetha i-Tracer Dream 150V TU 60A noma i-200V Pro 80A.

Ungakhohlwa Imikhawulo Ye-Voltage

Abalawuli be-MPPT nabo bane-voltage ephezulu ye-PV evulekile (i-Voc). Hlanganisa i-Voc yamaphaneli ngochungechunge bese uyigcina okungenani ingu-20% ngaphansi komkhawulo wesilawuli. Iyunithi engu-150V iphatha kahle izintambo eziningi ze-48V zokuhlala; i-200V Pro yakhelwe ama-array amakhulu ezentengiselwano.

Ishidi Lokukhohlisa Lokulinganisa Okusheshayo

• < 300W, 12V → 30A MPPT noma i-PWM yekhwalithi
• 300–800W, 12V/24V → 40–60A MPPT
• 800W–3kW, 24V/48V → 60–100A MPPT
• > 3kW → 100–120A MPPT (Tracer Dream F / 200V Pro)
