(1) Ngaphambi kokulungiswa, qala uqhawule uqhagamshelo lombane phakathi kwe-inverter kunye negridi, uze uqhawule uqhagamshelo lombane kwicala le-DC. Kuyimfuneko ukulinda ubuncinane imizuzu emi-5 okanye ngaphezulu ukuvumela i-capacitors ephezulu kunye nezinye izinto ezingaphakathi kwi-inverter ukuba zikhutshwe ngokupheleleyo ngaphambi kokwenza umsebenzi wokulondoloza.

(2) Kwinkqubo yokugcinwa komsebenzi, okokuqala, jonga ngokubonakalayo i-PV inverter kunoma yimuphi umonakalo okanye ezinye iimeko ezinobungozi kwaye ubeke ingqalelo kwi-anti-static kwinkqubo ethile yokusebenza, kungcono ukugqoka i-anti-static hand ring. Nika ingqalelo kwiimpawu zokulumkisa kwi-inverter kwaye ukhangele umphezulu we-inverter emva kokupholisa. Ngexesha elifanayo ukuphepha uqhagamshelwano olungeyomfuneko phakathi kweebhodi zomzimba kunye neesekethe.

(3) Emva kokuba ukugcinwa kugqityiwe, qiniseka ukuba naziphi na iziphoso ezichaphazela ukusebenza kokhuseleko lwe-inverter zisusiwe ngaphambi kokuba umbane kwi-inverter.

Unobangela wesehlo:

(1) Akukho mbane kwicala le-AC lemveliso ye-inverter, ukungasebenzi kwamandla okusebenza.

(2) Iitheminali ze-Inverter AC zemveliso aziqhagamshelwanga ngokufanelekileyo okanye umgca wetheminali ukhululekile.

Isisombululo:

(1) Nceda usebenzise i-multimeter ukulinganisa amandla ombane we-AC we-inverter, phantsi kweemeko eziqhelekileyo iitheminali zokuphuma kufuneka zibe nesigaba sombane we-380V;

(2) Nceda uvavanye ngokulandelelana ukuba iitheminali zikhululekile, ukuba i-AC ivaliwe i-breaker circuit ivaliwe okanye ayikho, kwaye ingaba isitshixo sokukhusela ukuvuza komhlaba sinqanyuliwe okanye cha.

Unobangela wesehlo: 

I-voltage kunye ne-frequency yegridi ye-AC iphuma kuluhlu oluqhelekileyo.

Isisombululo:

(1) Nceda ujonge amandla ombane wokubek' iliso kunye nedatha yembali yamaza ukuze ubone ukuba kukho nawaphi na amaxabiso aphuma kuluhlu lolawulo lokhuseleko.

(2) Nceda ulinganise umbane wegridi ye-AC nge-multimeter, ukuba ayiqhelekanga ngokwenene, uze ulinde ukuba igridi ibuyele kwesiqhelo.

(3) Nceda ujonge igalelo le-DC kunye ne-AC ye-inverter ye-inverter, vumela umbane we-inverter ucime ngaphezu kwe-30min ukuze ubone ukuba isiphaluka sombane sinokubuyiselwa ngokwaso, ukuba sinokubuyiselwa ngokwaso, unokuqhubeka nokuyisebenzisa, ukuba ayinakufunyanwa kwakhona, unokuqhagamshelana ne-Renac ukuze ufumane ingxelo yokulungisa.

Unobangela wesehlo:

Iimodyuli ezininzi kakhulu ziqhagamshelwe kuthotho ezibangela ukuba amandla ombane afakwe kwicala le-DC agqithe ubuninzi bombane osebenzayo we-inverter.

Isisombululo:

(1) Ngokweempawu zobushushu beemodyuli ze-PV, ubushushu obuphantsi be-ambient, kokukhona umbane ophumayo uphezulu. Kucetyiswa ukuba uqwalasele uluhlu lwe-voltage yomtya ngokwedatha ye-inverter.

(2) Kolu luhlu luqhelekileyo lwamandla ombane we-inverter, ukusebenza kakuhle kwe-inverter kuphezulu, kwaye i-inverter isenakho ukugcina imeko yokuvelisa amandla okuqalisa xa i-irradiance iphantsi kusasa nangokuhlwa, kwaye ayiyi kubangela ukuba i-voltage ye-DC igqithe umda ophezulu we-voltage ye-inverter, eya kukhokelela kwi-alamu kunye nokucima.

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!

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 kwi-terminal ye-MPPT yendlela enye, amandla aphumayo aya kuba sisiqingatha.
