FAQs ezinxulumeneyo
- 1.DC icala igalelo ombane overvoltage alarm, umyalezo imposiso "PV Overvoltage" eboniswe?
Unobangela wesehlo:
Iimodyuli ezininzi kakhulu ziqhagamshelwe kuthotho, okubangela ukuba i-voltage yegalelo kwicala le-DC igqithe ubuninzi bombane osebenzayo we-inverter.
Isisombululo:
Ngokweempawu zeqondo lokushisa kwiimodyuli ze-PV, iqondo lokushisa eliphantsi le-ambient, i-voltage ephezulu yokuphuma. Kucetyiswa ukuba uqwalasele uluhlu lwe-voltage yomtya ngokwedatha ye-inverter. Kolu luhlu lwamandla ombane, ukusebenza kakuhle kwe-inverter kuphezulu, kwaye i-inverter isenako ukugcina imeko yokuvelisa amandla okuqalisa xa i-irradiance iphantsi ekuseni nangokuhlwa, kwaye ayiyi kubangela ukuba i-voltage ye-DC igqithe umda ophezulu we-inverter voltage, eya kukhokelela kwi-alamu kunye nokucima.
- I-2.I-insulation performance ye-PV system iyancipha, ukuxhatshazwa kwe-insulation kumhlaba kungaphantsi kwe-2MQ, kunye nemiyalezo yephutha "I-Isolation error" kunye ne-"Isolation Fault" iboniswa.
Unobangela wesehlo:
Ngokuqhelekileyo iimodyuli ze-PV, iibhokisi ze-junction, iintambo ze-DC, ii-inverters, iintambo ze-AC, ii-terminals, kunye nezinye iindawo zomgca wokumisa i-short-circuit okanye umonakalo we-insulation layer, i-wireless string connectors emanzini, njalo njalo.
Isisombululo:
Ukuqhawula igridi, kunye ne-inverter, khangela ukuchasana kwe-insulation yecandelo ngalinye lekhebula emhlabeni, fumana ingxaki, kwaye ubeke indawo yekhebula elihambelanayo okanye isixhumi!
- 3.I-voltage ephumayo egqithisileyo kwicala le-AC, ebangela ukuba i-inverter ivale okanye ikhuphe ngokhuseleko?
Unobangela wesehlo:
Kukho izinto ezininzi ezichaphazela amandla okuphuma kwezityalo zamandla e-PV, kubandakanywa ubungakanani bemitha yelanga, i-angle ethambekileyo yemodyuli yeseli yelanga, uthuli kunye nokuphazamiseka kwesithunzi, kunye neempawu zokushisa zemodyuli.
Amandla enkqubo aphantsi ngenxa yokungalungelelaniswa kwenkqubo engafanelekanga kunye nofakelo.
Siinguqulelo :
(1) Vavanya ukuba ingaba amandla emodyuli nganye yePV anele phambi kofakelo.
(2) Indawo yokufakela ayinamoya kakuhle, kwaye ukushisa kwe-inverter akusasazekanga ngexesha, okanye kubonakaliswe ekukhanyeni kwelanga ngokuthe ngqo, okubangela ukuba ukushisa kwe-inverter kuphezulu kakhulu.
(3) Lungisa i-angle yokufakela kunye nokuqhelaniswa nemodyuli yePV.
(4) Jonga imodyuli yezithunzi kunye nothuli.
(5) Ngaphambi kokufaka iintambo ezininzi, khangela i-voltage evulekileyo yombane womtya ngamnye kunye nokwahlukana okungekho ngaphezu kwe-5V. Ukuba i-voltage ifunyenwe ingalunganga, khangela i-wiring kunye nezixhumi.
(6) Xa ufaka, inokufumaneka kwiibhetshi. Xa ufikelela kwiqela ngalinye, bhala amandla eqela ngalinye, kwaye ukuhlukana kwamandla phakathi kweentambo akufanele kube ngaphezu kwe-2%.
(7) I-inverter ine-MPPT yokufikelela kabini, indlela nganye yokufakelwa kwamandla yi-50% yamandla onke. Ngokomgaqo, indlela nganye kufuneka iyilwe kwaye ifakwe ngamandla alinganayo, ukuba idityaniswe kuphela kwindlela enye ye-MPPT, amandla aphumayo aya kuba sisiqingatha.

(9) Khangela ukuba ingaba i-voltage ingaphakathi koluhlu lwe-voltage emva kokuba izixhobo zixhunyiwe kuthotho, kwaye ukusebenza kakuhle kwenkqubo kuya kuncitshiswa ukuba i-voltage iphantsi kakhulu.
(10) Umthamo wegridi-eqhagamshelwe kwi-AC switch ye-PV yamandla ombane incinci kakhulu ukuhlangabezana neemfuno zemveliso ye-inverter.
