Amanothi ohlelo lokusebenza

1. Isingeniso Umthetho we-Italian udinga ukuthi wonke ama-inverter axhunywe kugridi aqale enze ukuzihlola kwe-SPI.Phakathi nalokhu kuzihlola, i-inverter ihlola izikhathi zohambo nge-voltage engaphezulu, ngaphansi kwe-voltage, i-over frequency kanye nangaphansi kwamafrikhwensi - ukuqinisekisa ukuthi isiguquli siyanqamuka lapho sidingeka...

1. Kuyini ukwehla kwezinga lokushisa?I-Derating ukunciphisa okulawulwayo kwamandla we-inverter.Ekusebenzeni okuvamile, ama-inverters asebenza endaweni yawo yamandla aphezulu.Kuleli phuzu lokusebenza, isilinganiso phakathi kwe-PV voltage kanye ne-PV yamanje iphumela emandleni aphezulu.Ubukhulu bephoyinti lamandla bushintsha ubungozi...

Ngokuthuthukiswa kobuchwepheshe bemojula ye-Cell ne-PV, ubuchwepheshe obuhlukahlukene obufana ne-half cut cell, i-shingling module, i-bi-face module, i-PERC, njll. ibekwe phezulu komunye nomunye.Amandla okukhiphayo kanye namandla emojuli eyodwa akhule kakhulu.Lokhu kuletha izidingo eziphakeme zokuguqula...

Liyini “iphutha lokuzihlukanisa”?Ezinhlelweni ze-photovoltaic ezine-inverter engaphansi kwe-transformer, i-DC ihlukaniswe nomhlabathi.Amamojula anokuhlukaniswa kwemojuli enesici, izintambo ezingavinjiwe, izilungiseleli zamandla ezinesici, noma iphutha langaphakathi le-inverter angabangela ukuvuza kwamanje kwe-DC phansi (PE - protective ...

1. Isizathu Kungani inverter kwenzeka overvoltage tripping noma ukuncipha amandla kwenzeka?Kungase kube esinye salezi zizathu ezilandelayo: 1) Igridi yangakini isivele isebenza ngaphandle kwemikhawulo yasendaweni Ejwayelekile yamandla kagesi (noma izilungiselelo zokulawula okungalungile).Isibonelo, e-Australia, i-AS 60038 icacisa ama-volts angama-230 njenge ...

Amazwe amaningi emhlabeni asebenzisa ukunikezwa okujwayelekile okungu-230 V (i-voltage yesigaba) kanye no-400V (amandla kalayini) anezintambo ezimaphakathi ku-50Hz noma ku-60Hz.Noma kungase kube nephethini yegridi ye-Delta yokuthutha amandla kanye nokusetshenziswa kwezimboni kwemishini ekhethekile.Futhi njengomphumela ohambelanayo, iningi le-solar inverte...

Izibalo ze-Solar Inverter String Design I-athikili elandelayo izokusiza ukubala umkhawulo / inani elincane lamamojula ngochungechunge lweyunithi ngayinye lapho uklama isistimu yakho ye-PV.Futhi ubukhulu be-inverter buhlanganisa izingxenye ezimbili, i-voltage, nosayizi wamanje.Ngesikhathi sokulinganisa inverter udinga ukuthatha...

Kungani kufanele sinyuse imvamisa yokushintshashintsha?Umthelela omningi wemvamisa ephezulu yokuguqula: 1. Ngokukhuphuka kwemvamisa yokushintshashintsha, ivolumu nesisindo se-inverter nakho kuyancishiswa, futhi ukuminyana kwamandla kuthuthukiswa kakhulu, okunganciphisa ngempumelelo isitoreji, ...

Kungani sidinga Isici Somkhawulo Wokuthekelisa 1. Kwamanye amazwe, imithetho yendawo ikhawulela inani leplanti yamandla ye-PV engafakwa kugridi noma ingavumeli ukuphakelwa, kuyilapho ivumela ukusetshenziswa kwamandla e-PV ukuze zizisebenzisele yona.Ngakho-ke, ngaphandle Kwesixazululo Sokukhawulela Ukuthekelisa, uhlelo lwe-PV alukwazi...
