Emhlabeni wezinhlelo zamandla avuselelekayo, ii-inverter ye-hybridime njengendawo emaphakathi, ehlela umdanso oyinkimbinkimbi phakathi kokuphehla amandla elanga, ukugcinwa kwebhethri, nokuxhumana kwegridi. Kodwa-ke, ukuzulazula olwandle lwamapharamitha wobuchwepheshe namaphoyinti edatha ahambisana nalezi zisetshenziswa eziyinkimbinkimbi ngokuvamile kungase kubonakale njengokuchaza ikhodi eyindida yabangawazi. Njengoba isidingo sezixazululo zamandla ahlanzekile siqhubeka nokwanda, ikhono lokuqonda nokuhumusha imingcele ebalulekile ye-hybrid inverter seliyikhono elibalulekile kubo bobabili ochwepheshe bamandla asebemnkantshubomvu kanye nabanikazi bezindlu abashisekayo abaqaphela imvelo ngokufanayo. Ukuvula izimfihlo ezigcinwe ngaphakathi kwe-labyrinth yemingcele ye-inverter akugcini nje ukunika abasebenzisi amandla okuqapha nokwandisa izinhlelo zabo zamandla kodwa futhi kusebenza njengesango lokukhulisa ukusebenza kahle kwamandla nokusebenzisa amandla aphelele ezinsiza zamandla avuselelekayo. Kulo mhlahlandlela obanzi, siqala uhambo lokususa ukungaqondakali kobunzima bokufunda imingcele ye-hybrid inverter, sihlomisa abafundi ngamathuluzi nolwazi oludingekayo ukuze bazulazule ngaphandle kokuzikhandla ubunkimbinkimbi bengqalasizinda yabo yamandla esimeme. 
Amapharamitha okokufaka kwe-DC (I) Ubukhulu bokufinyelela obuvunyelwe kumandla weyunithi yezinhlamvu ye-PV Ubukhulu bokufinyelela okuvunyelwe kumandla weyunithi yezinhlamvu ze-PV amandla aphezulu e-DC avunyelwe isiguquli ukuze axhume kuyunithi yezinhlamvu ye-PV. (ii) Amandla e-DC alinganiselwe Amandla e-DC alinganiselwe abalwa ngokuhlukanisa amandla okukhiphayo e-AC alinganiselwe ngokusebenza kahle kokuguqulwa nokwengeza imajini ethile. (iii) Umthamo omkhulu kagesi we-DC I-voltage ephezulu yochungechunge lwe-PV exhunyiwe ingaphansi kwe-voltage ephezulu ye-DC yokufaka ye-inverter, kucatshangelwa i-coefficient yokushisa. (iv) Ububanzi bamandla kagesi we-MPPT I-voltage ye-MPPT yochungechunge lwe-PV kucatshangelwa i-coefficient yezinga lokushisa kufanele ibe ngaphakathi kwebanga lokulandelela le-MPPT lesiguquli. Ibanga elibanzi le-MPPT voltage lingakwazi ukubona ukukhiqizwa kwamandla amaningi. (v) I-voltage eqalayo I-inverter eyi-hybrid iqala lapho umkhawulo wokuqala we-voltage weqiwa futhi iyavala lapho iwela ngaphansi komkhawulo wokuqala we-voltage. (vi) Ubuningi be-DC yamanje Lapho ukhetha i-inverter eyi-hybrid, ipharamitha yamanje ephezulu ye-DC kufanele igcizelelwe, ikakhulukazi lapho kuxhunywa amamojula wefilimu emincane ye-PV, ukuze kuqinisekiswe ukuthi ukufinyelela kwe-MPPT ngakunye kuntambo yamanje ye-PV kungaphansi kobukhulu bamanje be-DC be-hybrid inverter. (VII) Inani lamashaneli okufakwayo namashaneli e-MPPT Inani lamashaneli okokufaka we-hybrid inverter libhekisela enanini lamashaneli okufakwayo e-DC, kuyilapho inani lamashaneli e-MPPT libhekisela enanini lokulandelela amaphuzu aphezulu, inani lamashaneli okokufaka we-inverter eyi-hybrid ayilingani nenombolo Iziteshi ze-MPPT. Uma isiguquli esiyingxubevange sinokufaka okungu-6 DC, okokufaka ngakunye kokuthathu kwe-hybrid inverter kusetshenziswa okokufaka kwe-MPPT. I-MPPT yomgwaqo engu-1 ngaphansi kokufakwa kweqembu le-PV okuningana kudingeka ilingane, futhi okokufaka kwentambo ye-PV ngaphansi kwe-MPPT yomgwaqo ehlukene kungase kungalingani. Amapharamitha okukhiphayo kwe-AC (i) Amandla aphezulu e-AC Ubukhulu bamandla e-AC bubhekisela emandleni aphezulu angakhishwa isiguquli se-hybrid. Ngokuvamile, isiguquli se-hybrid siqanjwa ngokwamandla okukhiphayo e-AC, kodwa futhi aqanjwe ngokwamandla alinganiselwe okufakwayo kwe-DC. (ii) Ubuningi be-AC yamanje I-Maximum AC current iwumkhawulo wamanje ongakhishwa yi-hybrid inverter, enquma ngokuqondile indawo enqamula ingxenye yekhebula kanye nokucaciswa kwepharamitha yempahla yokusabalalisa amandla. Ngokuvamile, ukucaciswa kwe-circuit breaker kufanele kukhethwe izikhathi ezingu-1.25 zobukhulu bamanje be-AC. (iii) Okukhiphayo okukaliwe Okukhiphayo okulinganiselwe kunezinhlobo ezimbili zokuphuma kwefrikhwensi kanye nokukhishwa kwe-voltage. E-China, okukhiphayo imvamisa ngokuvamile kuba ngu-50Hz, futhi ukuchezuka kufanele kube phakathi kuka-+1% ngaphansi kwezimo ezijwayelekile zokusebenza. I-voltage ephumayo ine-220V, 230V, 240V, isigaba sokuhlukanisa i-120/240 njalonjalo. (D) isici samandla Kumjikelezo we-AC, i-cosine yomehluko wesigaba (Φ) phakathi kwe-voltage ne-current ibizwa ngokuthi i-power factor, evezwa uphawu lwe-cosΦ. Ngokwezinombolo, isici samandla isilinganiso samandla asebenzayo kumandla abonakalayo, okungukuthi, cosΦ=P/S. Isici samandla semithwalo ephikisanayo njengama-incandescent bulbs nezitofu zokumelana ngu-1, futhi isici samandla samasekhethi anemithwalo engenisayo singaphansi kuka-1. Ukusebenza kahle kwama-Hybrid inverters Kunezinhlobo ezine zokusebenza kahle ezisetshenziswayo: ukusebenza kahle okuphezulu, ukusebenza kahle kwe-Europe, ukusebenza kahle kwe-MPPT nokusebenza kahle komshini wonke. (I) Ukusebenza kahle okuphezulu:isho ukusebenza kahle okuphezulu kokuguqulwa kwesiguquli esiyingxubevange ngokuphazima kweso. (ii) Ukusebenza kahle kwe-Europe:Izisindo zamaphuzu wamandla ahlukene atholakala ezindaweni zamandla okufaka ehlukene e-DC, njenge-5%, 10%, 15%, 25%, 30%, 50% kanye no-100%, ngokuvumelana nezimo zokukhanya eYurophu, ezisetshenziswayo. ukulinganisa ukusebenza kahle konke kwe-inverter ye-hybird. (iii) Ukusebenza kahle kwe-MPPT:Ukunemba kokulandelela indawo enkulu yamandla ye-hybrid inverter. (iv) Ukusebenza kahle kukonke:iwumkhiqizo wokusebenza kahle kwe-European kanye nokusebenza kahle kwe-MPPT ku-voltage ethile ye-DC. Amapharamitha ebhethri (I) Ibanga lamandla kagesi Ibanga lamandla kagesi ngokuvamile libhekisela ebangeni lamandla kagesi elamukelekayo noma elinconyiwe lapho isistimu yebhethri kufanele isetshenziswe khona ukuze isebenze kahle nempilo yesevisi. (ii) Inani eliphezulu lokushaja/ukukhipha amandla Okokufaka/okukhiphayo okukhulu kwamanje konga isikhathi sokushaja futhi kuqinisekisa ukuthiibhethriigcwele noma iyaphuma ngesikhathi esifushane. Amapharamitha okuvikela (i) Ukuvikelwa kwesiqhingi Uma igridi iphelelwe amandla kagesi, uhlelo lokuphehla ugesi lwe-PV lusasigcina isimo sokuqhubeka nokuhlinzeka amandla engxenyeni ethile yolayini wegridi ephuma ngaphandle kwe-voltage. Okubizwa ngokuthi ukuvikelwa kwe-islanding ukuvimbela lo mphumela we-island ongahleliwe ukuthi ungenzeki, ukuqinisekisa ukuphepha komuntu siqu komqhubi wegridi kanye nomsebenzisi, nokunciphisa ukuvela kwamaphutha emishini yokusabalalisa kanye nemithwalo. (ii) Okokufaka kokuvikela i-overvoltage Ukuvikelwa kokufakwayo kwe-overvoltage, okungukuthi, lapho i-voltage eseceleni yokufaka ye-DC ingaphezulu kwe-voltage enkulu yokufinyelela yesikwele ye-DC evunyelwe i-hybridinverter, i-hybridinverter ngeke iqale noma ime. (iii) Ukuvikelwa kohlangothi lokuphumayo kwe-overvoltage/undervoltage Ukuvikelwa kohlangothi lokuphumayo kwe-overvoltage/undervoltage kusho ukuthi isiguquli esiyingxubevange sizoqala isimo sokuvikela lapho i-voltage esehlangothini lokuphumayo le-inverter ingaphezulu kwenani eliphakeme le-voltage ephumayo evunyelwe isiguquli noma iphansi kunenani eliphansi le-voltage ephumayo evunyelwe i-inverter. Isikhathi sokuphendula se-voltage engavamile ohlangothini lwe-AC lwe-inverter kufanele sihambisane nezinhlinzeko ezithile zezinga elixhunywe kugridi. Ngekhono lokuqonda imingcele yokucaciswa kwe-hybrid inverter,abadayisi belanga nabafakeli, kanye nabasebenzisi, bangakwazi ukucacisa kalula ububanzi bamandla kagesi, amandla okulayisha, nezilinganiso ezisebenza kahle ukuze babone amandla aphelele ezinhlelo zokuguqula izinto eziyingxubevange, bathuthukise ukusetshenziswa kwamandla, futhi banikele ekusaseni elizinzile nelinobungani bemvelo. Esimeni esiguquguqukayo samandla avuselelekayo, ikhono lokuqonda nokusebenzisa amapharamitha we-hybrid inverter lisebenza njengetshe legumbi lokugqugquzela isiko lokusebenza kahle kwamandla kanye nokuphathwa kwemvelo. Ngokwamukela imininingwane eyabiwe kulo mhlahlandlela, abasebenzisi bangazulazula ngokuzethemba izinto eziyinkimbinkimbi zezinhlelo zabo zamandla, benze izinqumo ezinolwazi futhi bamukele indlela esimeme futhi eqinile ekusetshenzisweni kwamandla.
