Isichasiso
Isimangaliso se-Ispunomenon senzeka ezinhlelweni ze-Photovoltaic eziboshwe nge-Photovoltaic (PV) lapho i-grid ithola ukuphuma kwamandla, kepha uhlelo lwe-PV luyaqhubeka nokunikeza amandla emithwalweni exhunyiwe. Lokhu kwakha "isiqhingi" esisendaweni yesizukulwane samandla.
Izingozi Zesiqhingi
- Izingozi Zokuphepha: Ubungozi kubasebenzi bokusebenzisa ukulungisa igridi.
- Ukulimala kwemishini: Izakhi zikagesi zingasebenza kahle ngenxa ye-voltage engazinzile kanye nemvamisa.
- Ukungakwazi kwegridi: Iziqhingi ezingalawulwa zingaphazamisa ukusebenza okuvumelanisiwe kwegridi enkulu.
2. Izici ezibalulekile namapharamitha we-inverters efanelekile
Izici ezibalulekile ze-Inverters
- Ukuvikelwa kwe-Anti-Island: Kusebenzisa izindlela ezisebenzayo nezingenamikhawulo zokuthola ukuvala ngokushesha ngesikhathi sehluleke segridi.
- I-MPPT esebenza kahle: Khulisa ukuguqulwa kwamandla kusuka kumaphaneli e-PV.
- Ukusebenza kahle okuphezulu: Ngokuvamile> 95% ukunciphisa ukulahleka kwamandla.
- Ukuxhumana okuhlakaniphile: Usekela amaphrothokholi anjenge-Rs485, i-Wi-Fi, noma i-Ethernet yokuqapha.
- Ukuphathwa okukude: Ivumela ukuqapha kanye nokulawula uhlelo ukude.

3. Ukuxhumeka phakathi kokukhethwa kwamakhebula we-PV nokuvinjwa kwesiqhingi
Ukubaluleka Kwezintambo ze-PV
Izintambo ze-PV ezisezingeni eliphakeme zidlala indima ebalulekile ekulondolozeni ukuqina kohlelo kanye nokuqinisekisa ukutholwa okunembile kwezimo zegridi, okubaluleke kakhulu ezinhlanganweni ezilwa neziqhingi.
- Ukudluliselwa kwamandla okusebenzayo: Yehlisa amaconsi kagesi kanye nokulahleka kwamandla, ukuqinisekisa ukugeleza kwamandla okungaguquki ku-inverter.
- Ukunemba kwesiginali: Inciphisa umsindo kagesi nokuhlukahluka kwe-Impodance, kuthuthukisa amandla we-inverter ukuthola ukwehluleka kwegridi.
- Ukuqina: Iqinisekisa ukuthembeka kwesikhathi eside ezimweni ezahlukahlukene zezemvelo, ukugcina ukusebenza okuqinile.
4. KunconyiweIzintambo ze-PV zama-systems aboshwe ngegridi
Izinketho eziphezulu ze-PV Cable
- Ev h1z2z2-k
- Izici: Intuthu ephansi, i-halogen-free, ukumelana nesimo sezulu esiphakeme.
- Ukuthobela: Ihlangana namazinga we-IEC 62930.
- Izinja: Izinhlelo ezifakwe emhlabathini kanye nophahla lwePV.
- Tuv Pv1-F
- Izici: Ukumelana kwamazinga okushisa okuhle (40 ° C kuya ku-90 ° C).
- UkuthobelaIsitifiketi se-TÜV samazinga aphezulu okuphepha.
- Izinja: Kusatshalaliswa izinhlelo ze-PV kanye ne-AgriVoltaics.
- Izintambo ze-PV ezihlotshisiwe
- Izici: Ukuvikelwa okuthuthukile okuthuthukisiwe nokuqina.
- Ukuthobela: Ihlangabezana neEC 62930 ne-EN 60228 amazinga.
- Izinja: Izinhlelo ze-PV-scale PV nezindawo ezinokhahlo.
