Cov cuab yeej tseem ceeb ntawm Photovoltaic Off-Grid System

Lub photovoltaic off-grid system muaj xws li hnub ci modules, hnub ci controllers, roj teeb (paub pawg), thiab off-grid inverters. Nws yog qhov tsim nyog rau cov cheeb tsam uas tsis muaj kab sib txuas lossis tsis ruaj khov ntawm daim phiaj-txuas fais fab. Photovoltaic off-grid systems yog cov kev daws teeb meem ntawm tus kheej uas tuaj yeem ntsia tau rau hauv ntau qhov chaw thiab yooj yim los tswj, txhim khu kev qha, huv, thiab pheej yig.

Cov cuab yeej tseem ceeb ntawm photovoltaic off-grid system yog raws li hauv qab no:

1. Hnub ci photovoltaic modules.

Hloov lub hnub ci zog rau hauv hluav taws xob hluav taws xob, lossis xa mus rau cov roj teeb cia, yog ib feem tseem ceeb ntawm lub hnub ci hluav taws xob tsim hluav taws xob. Irradiation yam ntxwv thiab kub yam ntxwv yog ob yam tseem ceeb uas cuam tshuam rau kev ua tau zoo ntawm cov khoom.

2. Off-grid inverters.

Lub zog hluav taws xob hloov pauv los ntawm hnub ci photovoltaic modules yog tam sim no ncaj qha, thiab peb cov khoom siv niaj hnub siv hloov pauv tam sim no. Lub inverter yog ib qho khoom siv uas hloov tam sim no ncaj qha (DC) mus rau qhov hloov pauv tam sim no (AC) thiab muaj cov choj inverter, tswj cov logic, thiab lim circuits.

3. Solar maub los.

Kev siv lub hnub ci loj tshaj plaws yog los tiv thaiv lub roj teeb, tom qab ntawd kev tiv thaiv kev tiv thaiv kev tiv thaiv, kev tiv thaiv luv luv, kev tiv thaiv overcharge thiab kev tiv thaiv tshaj tawm, thiab lwm yam ntxiv rau qhov no, nws muaj kev tswj hwm lub zog thiab kev sib txuas lus. Hnub ci tswj tau muab faib ua PMW hom thiab MPPT hom.

4. Roj teeb.

Lub roj teeb yog lub zog cia khoom ntawm photovoltaic off-grid system. Nws txoj haujlwm yog khaws cov hluav taws xob hluav taws xob hloov pauv los ntawm lub hnub ci module thiab muab lub zog rau cov khoom thauj thaum lub sijhawm siv hluav taws xob.

5. Lwm yam khoom siv, xws li photovoltaic brackets, tis thawv, cables, thiab lwm yam.
