Indlela yokwahlulela ikhwalithi ye-inverter?

Iziguqulizingamathuluzi abalulekile ezinhlelweni zikagesi zesimanje eziguqula i-direct current (DC) ibe i-alternating current (AC) ukuze inike amandla izinto ezisetshenziswayo namasistimu ahlukahlukene. Kungakhathaliseki ukuthi okokuhlala, ukuhweba noma ukusetshenziswa kwezimboni, ikhwalithi ye-inverter ingaba nomthelela omkhulu ekusebenzeni kahle, ukwethembeka kanye nokuphila isikhathi eside kokufaka kwakho ugesi. Lesi sihloko sizokuqondisa ezintweni ezibalulekile okufanele uzicabangele lapho wahlulela ikhwalithi ye-inverter.

1. Ukusebenza kahle

Incazelo Nokubaluleka

Ukusebenza kahle isilinganiso samandla okukhiphayo kumandla okufakwayo, avezwa njengephesenti. Iziguquli ezisebenza kahle kakhulu ziguqula amandla e-DC engeziwe abe amandla asebenzisekayo e-AC, ehlisa ukulahleka kwamandla.

Indlela yokuhlola

-Izicaciso Zomkhiqizi: Hlola isilinganiso sokusebenza kahle esinikezwe umenzi. Ama-inverter ekhwalithi ephezulu ngokuvamile anezilinganiso zokusebenza kahle ezingaphezu kuka-90%.

- IZIVIVINYO EZINGAZIMELE: Bheka imiphumela yokuhlolwa evela eceleni noma izitifiketi ezivela ezinhlanganweni ezinedumela elihle, njengeCalifornia Energy Commission (CEC) noma i-TÜV Rheinland.

2. Ukuhlanekezela okuphelele kwe-harmonic (THD)

Incazelo Nokubaluleka

I-THD ikala ukuhlanekezela komphumela we-waveform uma kuqhathaniswa negagasi le-sine elimsulwa. I-THD ephansi isho amandla ahlanzekile, abalulekile kuma-electronics abucayi nezinto zikagesi.

Indlela yokuhlola

Isilinganiso se-THD: Ama-inverter ekhwalithi ephezulu ngokuvamile ane-THD engaphansi kuka-3%. Ama-inverters e-sine wave ahlanzekile ngokuvamile ahlinzeka nge-THD ephansi kakhulu.

-Ukubuyekezwa komsebenzisi: Hlola ukubuyekezwa komsebenzisi nezinkundla ukuze uthole impendulo yokusebenza kwangempela kuTHD.

3. Yakha ikhwalithi nokuqina

Incazelo Nokubaluleka

Ikhwalithi yokwakha nokuqina kwe-inverter inquma amandla ayo okumelana nezimo ezinzima kanye nokusetshenziswa kwesikhathi eside.

Indlela yokuhlola

-Materials: I-casing of high quality inverters yenziwe ngezinto eziqinile ezifana ne-aluminium noma ipulasitiki yezinga eliphezulu.

-I-Thermal: Isistimu yokupholisa esebenzayo (njengama-radiator namafeni) iyinkomba yekhwalithi enhle yokwakha.

-Ingress Protection (IP) Isilinganiso: Isilinganiso se-IP sibonisa izinga lokuvikela othulini namanzi. Ngokusetshenziswa kwangaphandle, bheka imikhiqizo elinganiselwe ngo-IP65 noma ngaphezulu.

4. Izici Nemisebenzi

Incazelo Nokubaluleka

Izici ezithuthukile nemisebenzi ithuthukisa ukusebenza kwe-inverter nolwazi lomsebenzisi.

Indlela yokuhlola

-Ukuqapha Nokulawula: Ama-inverter ekhwalithi ephezulu avame ukuhlonyiswa ngezinhlelo zokuqapha ezihlinzeka ngedatha yesikhathi sangempela ekusebenzeni, ukusebenza kahle, kanye namaphutha.

-Ikhono le-Grid tie: Ukufakwa kwe-solar, i-inverter ye-grid tie ikuvumela ukuthi ubuyisele amandla engeziwe kugridi.

-Ukuhambisana Kwebhethri: Amanye ama-inverters ahambisana nezinhlobo zebhethri ezihlukahlukene, kufaka phakathi i-lithium-ion ne-lead-acid, ehlinzeka ngokuguquguquka okukhulu.

5. Izici Zokuphepha

Incazelo Nokubaluleka

Izici zokuphepha zivikela i-inverter nezinto ezixhunyiwe ekulimaleni okudalwe amaphutha kagesi.

Indlela yokuhlola

-Overload Protection: Vimbela umonakalo obangelwa ukugcwala.

-Short Circuit Protection: Vimbela isifunda esifushane.

-Ukuvikela ukushisa ngokweqile: Vala i-inverter uma ishisa kakhulu.

-Izitifiketi: Bheka izitifiketi zokuphepha ezivela ezinhlanganweni ezifana ne-Underwriters Laboratories (UL) noma i-International Electrotechnical Commission (IEC).

6. Iwaranti kanye Nokusekela

Incazelo Nokubaluleka

Iwaranti enhle nokwesekwa kwamakhasimende okuthembekile kuyizinkomba zokuzethemba komkhiqizi emkhiqizweni wawo.

Indlela yokuhlola

-ISIQINISEKISO: Ama-inverter ekhwalithi ephezulu ngokuvamile anewaranti yeminyaka emi-5 noma ngaphezulu.

-Ukwesekwa Kwamakhasimende: Hlola ukutholakala kokusekelwa kwamakhasimende kanye nokusabela ngezibuyekezo nemibuzo eqondile.

7. Idumela lomkhiqizo

Incazelo Nokubaluleka

Isithunzi somkhiqizo singanikeza ukuqonda ngekhwalithi isiyonke ye-inverter nokuthembeka.

Indlela yokuhlola

-Ithonya Lemakethe: Imikhiqizo eyaziwayo enomlando omude emakethe ivame ukwethenjwa kakhulu.

-Ukubuyekezwa komsebenzisi: Ukubuyekezwa okuku-inthanethi nobufakazi kunganikeza imininingwane ebalulekile ekusebenzeni kwe-inverter nokuthembeka.

-Imiklomelo Yemboni: Ukuqashelwa noma imiklomelo evela emigwaqweni yezimboni ingasebenza njengezinkomba ezinhle zekhwalithi.

8. Izindleko vs. Inani

Incazelo Nokubaluleka

Nakuba izindleko ziyisici esibalulekile, kufanele zikalwe ngenani isiguquli esilinikezayo ngokuya ngokusebenza, ukusebenza kahle, nokwethembeka.

Indlela yokuhlola

-Izindleko Zokuqala: Qhathanisa izindleko zokuqala kwamanye ama-inverters anikeza izici ezifanayo kanye nokucaciswa.

-Ukonga amandla esikhathi eside: Cabangela ukonga amandla okungaba khona kwe-inverter esebenza kahle kakhulu.

-Return on Investment (ROI): Imbuyiselo ku-investimenti ibalwa ngokusekelwe empilweni yesevisi ye-inverter, ukusebenza kahle kanye nokonga kwamandla okungenzeka.

Ekuphetheni

Ukwahlulela ikhwalithi ye-inverter kudinga ukuhlolwa okuphelele kwezinto ezihlukahlukene, okuhlanganisa ukusebenza kahle, i-THD, ikhwalithi yokwakha, ukusebenza, ukuphepha, iwaranti, isithunzi somkhiqizo, kanye nezindleko. Ngokucabangela lezi zici ngokucophelela, ungenza isinqumo esinolwazi futhi ukhethe inverter ehlangabezana nezidingo zakho futhi inikeza ukusebenza okuthembekile iminyaka ezayo. Khumbula, ukutshala imali ku-inverter yekhwalithi ephezulu akuqinisekisi ukusebenza kahle kwesistimu yakho kagesi, kodwa futhi kunomthelela ekongeni amandla isikhathi eside kanye nokusimama.

Uma udinga ama-inverters, wamukelekile ukuthintana nomphakeli we-sine wave inverter Radiance weulwazi olwengeziwe.
