INDLELA YOKUFAKA INKQUBO YAKHO ye-SOLAR PV

2021-04-01

Xa udibanisaSlocableInkqubo yesolar pv, eyona ndlela ifanelekileyo yokongeza isiqinisekiso kukusebenzisaIifizi zeMC4 or abaphuli beesekethe zelanga.Ukusetyenziswa ngokuchanekileyo kwe-fuses kunye nee-breaker circuiters kubalulekile ukugcina ukhuseleko.I-Fuse kunye ne-breaker circuit zisetyenziselwa ukukhusela i-wiring ekutshiseni ngokugqithiseleyo kwaye zikhusele zonke izixhobo eziqhagamshelwe kwisistim ekuqhumeni amadangatye okanye ukwenzakala ukuba isekethe emfutshane iyenzeka.Umzekelo omhle yi-12V ibhetri ye-asidi ekhokelayo.Ukuba imfutshane ikhula kwi-inverter ye-AC/DC yakho umzekelo, ifyuzi phakathi kwayo kunye nebhetri iya kuthintela ugqabhuko-dubulo olunokwenzeka lwebhetri kwaye iya kunqumla isekethe ngokukhawuleza ngokwaneleyo ukuthintela iingcingo ukuba zingagqabhuki zibe ngamadangatye okanye zibe shushu ngokuyingozi.Kule meko, ibhetri, iingcingo, kunye ne-AC/DC inverter iya kukhutshazwa ngokukhuselekileyo yifuse.Akuyimfuneko ukuba inkqubo isebenze ngokufanelekileyo, kodwa sihlala sicebisa ukusebenzisa i-fuses okanye ii-circuit breakers ngeenjongo zokhuseleko.Kukho iindawo ezintathu ezahlukeneyo esicebisa ukufaka iifuse okanye i-breakers: okokuqala, phakathi komlawuli wentlawulo kunye nebhanki yebhetri, okwesibini, phakathi komlawuli wentlawulo kunye neepaneli zelanga, kwaye okwesithathu kuya kuba phakathi kwebhanki yebhetri kunye ne-inverter.

Ukumisela isayizi yefuse efunekayo phakathi kwesilawuli sentlawulo kunye nebhanki yebhetri, udibanisa ngokulula umlinganiselo we-amperage kwisilawuli sentlawulo.

I-fuse yesibini phakathi kweephaneli zakho zelanga kunye nesilawuli sokutshaja yahluke ngandlel' ithile ukuyiqonda.Ubungakanani bale fuse buxhomekeke ekubeni zingaphi iiphaneli zelanga onazo kunye nendlela ezidityaniswe ngayo (uthotho, ukungqamana, okanye uthotho/ukuhambelana).Ukuba iipaneli zixhunyiwe kuchungechunge, i-voltage yepaneli nganye yongezwa kodwa i-amperage ihlala ifana.Umzekelo, ukuba uneephaneli ezine ze-100W eziqhagamshelwe kuthotho, nganye ivelisa ii-volts ezingama-20 kunye nee-amps ezi-5, isiphumo sisonke siya kuba yi-80 volts kunye ne-5 amps.Emva koko sithatha i-amperage iyonke kwaye siyiphindaphinde ngokhuseleko lwe-25% (5A x 1.25) isinika i-fuse rating ye-6.25A okanye i-10A ukuba siyasondeza.Ukuba unoqhagamshelo olunxuseneyo, apho i-amperage yeephaneli yongezwa kodwa amandla ombane ahlala ayafana, kuya kufuneka udibanise i-amperage yephaneli nganye kwaye emva koko songeze umthetho we-25% weshishini ukufumana ubungakanani befuse.Umzekelo, ukuba ubune 100W iiphaneli ezine ezidityaniswe ngokunxuseneyo, indawo yolawulo nganye ivelisa malunga nee-Amps ezi-5, ngoko besizakusebenzisa lenxaki (4 * 5 * 1.25) = 28.75 Amps, ngoko ke kulo mzekelo singacebisa i-30 Amp fuse. .

Iiphaneli zelanga zorhwebo ezineewathi ezingaphezu kwama-50 zineecingo ezili-10 zegeyiji kwaye ziyakwazi ukumelana nemisinga ukuya kuthi ga kwi-amps ezingama-30.Ukuba ezi panels zidibaniswe kuchungechunge, okwangoku akusayi kunyuka, ngoko ke umtya awufuni ukuxutywa.Xa udibanisa iipaneli ngokuhambelanayo, oku akunjalo, kuba xa uqhagamshelwe ngokufanayo, i-currents system idibanisa.Ngokomzekelo, ukuba unamapaneli angama-4, elowo unokubonelela nge-15A yangoku, isiphaluka esifutshane kwiphaneli enye iya kubangela ukuba yonke i-60 A yangoku iqhubele kwiphaneli emfutshane.Oku kuya kubangela ukuba iingcingo ezikhokelela kwindawo yolawulo ukuba zigqithe kakhulu kwii-amps ezingama-30, nto leyo enokubangela ukuba izibini ezimbini zeengcingo zibambe umlilo.Ukuba yiphaneli enxuseneyo, indawo yolawulo nganye idinga i-30 amp fuse.Ukuba indawo yolawulo yakho ingaphantsi kweewatts ezingama-50 kwaye usebenzisa i-12 yocingo lwegeji kuphela, udinga i-20 amp fuse.

I-fuse yokugqibela esiyicebisayo kwisixokelelwano inokuba kuxa usebenzisa i-inverter.I-wiring kunye ne-fusing ukusuka kwibhetri ukuya kwi-inverter ye-AC / DC ibaluleke kakhulu kuba yilapho ubuninzi bangoku buhamba khona.Le fuse iya kuba phakathi kwe-inverter yakho kunye nebhanki yebhetri.Ubungakanani befuse buqhele ukuxelwa kwincwadana kwaye uninzi lwee-inverters kusenokwenzeka ukuba zibe nezakhelwe ngaphakathi iifuse/iziqhawuli zesekethe kumacala esixhobo kunye nemveliso (AC) yesixhobo.Umgaqo wesithupha esiwusebenzisayo apha uya kuba “IiWatts eziqhubekayo / amaxesha ombane webhetri 1.25, umzekelo isiguquli esiqhelekileyo se-1000W 12V sitsala malunga ne-83 yee-amps eziqhubekayo kwaye siya kongeza i-25% yokhuseleko into ephuma kwi-105 Amps, ngoko thina ingacebisa i-150A fuse.

Esi sisingeniso esifutshane kunye nesishwankathelo sokudibanisa inkqubo yakho.Kukho ezinye iinkalo ezifana nobukhulu bentambo / ubude kunye neentlobo ze-fuse / i-breaker ezibalulekileyo.Ungathumela i-imeyilengolwazi oluthe kratya malunga neemveliso zelanga!Ukuba uthatha ixesha lakho kwaye usebenzise indibaniselwano elungileyo yamacandelo alinganisiweyo, ke inkqubo kufuneka isebenze kakuhle kwaye uya kulala ngcono usazi ukuba uyinjineli ukuba ikhuseleke kwaye ithembekile.
