Hnub ci modules

 

Lub hnub ci cell tsuas tuaj yeem tsim tau li ntawm 0.5V, uas yog qis dua li qhov hluav taws xob xav tau rau kev siv tiag tiag. Yuav kom ua tau raws li cov kev xav tau ntawm cov kev siv tswv yim, lub hnub ci hnub ci yuav tsum tau txuas rau hauv cov modules. Lub hnub ci module muaj qee cov xov tooj ntawm lub hnub ci uas txuas nrog cov xov hlau. Piv txwv li, tus naj npawb ntawm lub hnub ci ntawm lub module yog 36, uas txhais tau hais tias lub hnub ci module tuaj yeem tsim txog 17V ntawm qhov hluav taws xob.
Lub hnub ci cell module yog qhov koj tau txais thaum koj xaim ua ke hnub ci hlwb. Nws yog tsim los tiv thaiv corrosion, cua, lawg, thiab nag, yog li nws tuaj yeem siv rau txhua qhov chaw thiab tshuab. Thaum daim ntawv thov teb yuav tsum muaj qhov hluav taws xob siab thiab tam sim no thiab ib qho module tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, ntau lub modules tuaj yeem tsim rau hauv lub hnub ci cell array kom tau txais qhov xav tau voltage thiab tam sim no.

 

Does an off-grid solar system need an inverter?

DC / AC inverter

 

Ib qho khoom siv uas hloov tam sim no ncaj qha mus rau qhov hloov pauv tam sim no. Txij li thaum lub hnub ci cell emits ncaj qha tam sim no, thiab qhov dav dav yog qhov hloov pauv tam sim no, lub inverter yog qhov tseem ceeb. Raws li kev ua haujlwm hom, lub inverter tuaj yeem muab faib ua haujlwm ywj pheej inverter thiab kab sib chaws- txuas inverter. Stand-ib leeg inverters yog siv nyob rau hauv sawv ntsug-ib leeg lub hnub ci hluav taws xob tsim tshuab hluav taws xob rau lub hwj chim ywj pheej. Daim phiaj-tied inverter: Lub hnub ci hluav taws xob tsim hluav taws xob siv rau daim phiaj- txuas ua haujlwm pub cov hluav taws xob tsim hluav taws xob rau hauv daim phiaj. Raws li cov zis waveform, lub inverter yuav muab faib ua square wave inverter thiab sine wave inverter.

Kev faib tawm chav tsim

 

Vim tias daim phiaj - txuas lub zog tsim hluav taws xob tsis muaj roj teeb, lub hnub ci them nqi hluav taws xob thiab cov hluav taws xob hluav taws xob thiab AC thiab DC faib qhov system, yog li, yog tias muaj kev tso cai, lub inverter ntawm daim phiaj - txuas hluav taws xob tsim hluav taws xob tuaj yeem muab tso rau hauv qhov qis -voltage faib chav tsev ntawm daim phiaj- txuas hluav taws xob tsim hluav taws xob, txwv tsis pub 4 ~ 6 volt tsuas yog 2.

 

Kev tiv thaiv xob laim ntawm daim phiaj- txuas hluav taws xob tsim hluav taws xob

 

Txhawm rau ua kom muaj kev nyab xeeb ntawm lub kaw lus nyob rau hauv huab cua hnyav xws li thunderstorms, kev tiv thaiv xob laim yuav tsum tau ua rau lub kaw lus no. Lub ntsiab tseem ceeb yog raws li nram no:
(1) Cov xaim hauv av yog tus yuam sij rau kev tiv thaiv xob laim thiab kev tiv thaiv xob laim, thaum ua tiav kev tsim kho vaj tse ntawm chav faib khoom thiab kev tsim kho vaj tse ntawm lub hnub ci cell array, xaiv qhov chaw nrog cov av tuab thiab ntub dej ze ntawm lub tshuab hluav taws xob photovoltaic, khawb 2m tob hauv av xaim pit, siv 40 ca steel, ntxiv tus neeg saib xyuas kom txo qis thiab coj tawm hauv av xaim, thiab 5 txhuas hlau 2 hli yuav tsum tau txais kev tiv thaiv ntawm cop. 1 Ω.
(2) Tsim kom muaj xob laim ze ntawm chav faib khoom, 15m siab, cov xaim hauv av txuas nrog cov xaim hauv av ntawm chav faib khoom, thiab cov xaim hauv av ntawm chav faib khoom faib cov xaim hauv av!
(3) Qhov voltage ntawm lub hnub ci cell array cable nkag mus rau hauv chav faib khoom yog DC220V, thiab cov yeeb nkab PVC yog faus thiab tiv thaiv los ntawm kev tiv thaiv xob laim. Tsis tas li ntawd, lub bracket ntawm lub hnub ci vaj huam sib luag square array yuav tsum xyuas kom zoo hauv av thiab tseem txuas nrog hauv av xaim ntawm chav faib khoom.
(4) AC tso zis kab ntawm daim phiaj- txuas inverter txais thawj - theem tiv thaiv ntawm lub thawv tiv thaiv xob laim (muaj AC tso zis hluav taws xob tiv thaiv hauv daim phiaj- txuas inverter).
