Amandla e-AC kunye ne-DC Power
Ngokuqhelekileyo into esiyibiza ngokuba yi-DC, ithetha umsinga othe ngqo, ii-electron zihamba ngokuthe tye, zisuka kwi-positive ukuya kwi-negative; I-AC imele i-alternating current, eyahlukileyo kwi-DC, i-directional yayo iyatshintsha ngokuhamba kwexesha, i-AC inokuhambisa amandla ngokufanelekileyo, ngoko iyasebenza kubomi bethu bemihla ngemihla kwizixhobo zendlu. Umbane oveliswa ngeepaneli zelanga ze-photovoltaic ziyi-DC ngokusisiseko, kwaye amandla nawo agcinwe ngendlela ye-DC kwinkqubo yokugcina amandla elanga.
Yintoni i-AC Coupling Solar System?
Ngoku sele simisele iqonga, masingene kwisihloko sethu sokuqala – ukudityaniswa kwe-AC. Limalunga nantoni kanye kanye eli gama lingaqondakaliyo?
Ukudityaniswa kwe-AC kubhekiselele kwinkqubo yokugcina ibhetri apho iipaneli zelanga kunye neebhetri ziqhagamshelwe kwicala elitshintshayo langoku (AC) le-inverter. Ngoku siyazi ukuba iinkqubo ze-photovoltaic zivelisa umbane we-DC, kodwa kufuneka siguqulele kumbane we-AC kwizixhobo zorhwebo kunye nekhaya, kwaye kulapho iinkqubo zebhetri ezidibeneyo ze-AC zibalulekile. Ukuba usebenzisa inkqubo edibeneyo ye-AC, ngoko kufuneka ungeze inkqubo entsha yokuguqula ibhetri phakathi kwenkqubo yebhetri yelanga kunye ne-PV inverter. I-inverter yebhetri inokuxhasa ukuguqulwa kwe-DC kunye ne-AC amandla avela kwiibhetri zelanga, ngoko ke iipaneli zelanga akufanele zidibaniswe ngokuthe ngqo kwiibhetri zokugcina, kodwa kuqala uqhagamshelane ne-inverter exhunywe kwiibhetri. Kolu seto:
- Iiphaneli zesola zivelisa umbane weDC
- Isiguquli selanga siyiguqulela kwi-AC
- Amandla e-AC athi aqukuqelele kwizixhobo zasekhaya okanye kwigridi
- Nawaphi na amandla angaphezulu kwe-AC aguqulwa abuyele kwi-DC ukutshaja iibhetri
Kodwa kutheni udlula kuzo zonke ezo nguqulelo? Ewe, ukudityaniswa kwe-AC kunezibonelelo ezithile eziphambili:
- Ukufakela kwakhona ngokulula:Inokongezwa kwiinkqubo ezikhoyo zelanga ngaphandle kweenguqu ezinkulu
- Ukuba bhetyebhetye:Iibhetri zinokubekwa kude kwiipaneli zelanga

A1: Ngelixa inokwenzeka, ayikhuthazwa ngokubanzi ngenxa yelahleko esebenzayo kunye nemiba yokuhambelana. Kungcono ukunamathela kwindlela enye yokusebenza kakuhle.
I-Q2: Ingakanani i-DC coupling esebenzayo xa kuthelekiswa nokudibanisa kwe-AC?
A2: Ukudityaniswa kwe-DC ngokuqhelekileyo kusebenza kakuhle nge-3-5%, ukuguqulela kugcino lwamandla olubalulekileyo kubomi benkqubo.
I-Q3: Ngaba ukudityaniswa kwe-AC kuhlala kulula ukubuyisela kwiinkqubo ezikhoyo zelanga?
A3: Ngokubanzi, ewe. Udibaniso lwe-AC ludla ngokufuna utshintsho olumbalwa, luyenze lube lula kwaye lusoloko luneendleko ezithe xhaxhe kwiiretrofits.
I-Q4: Ngaba iinkqubo ezidityanisiweyo ze-DC zingcono kubomi obungaphandle kwegridi?
A4: Ewe, iisistim ezidityanisiweyo ze-DC zisebenza ngakumbi kwizicelo ezizimeleyo kwaye zifaneleke ngcono kumthwalo othe ngqo we-DC, zizenza zilungele ukuseta ngaphandle kwegridi.
I-Q5: Yeyiphi indlela yokudibanisa ingcono kukwandiswa kwexesha elizayo?
I-A5: Ukudibanisa kwe-AC kunika ukuguquguquka okungaphezulu kokwandiswa kwexesha elizayo, ukuhambelana noluhlu olubanzi lwamacandelo kunye nokulula ukunyusa.
