Isikhethi seDC

123

Owona matshini uyilwe kakuhle kwindalo iphela ngumzimba womntu. Inendlela eyakhekileyo yokuzikhusela kunye nokuzilungisa. Nokuba le nkqubo ikrelekrele kakhulu ifuna ukulungiswa nokulungiswa ngamanye amaxesha. Kwaye njalo ngenkqubo nganye eyenziwe ngumntu, kubandakanya ukufakelwa kwelanga nge-PV. Ngaphakathi kufakelo lwelanga kukho inverter efumana i-Direct yangoku (DC) kwimitya yelanga njengegalelo kwaye ikhupha i-AC yangoku (AC) kwigridi kwisiphelo sesiphumo. Ngexesha lofakelo, ulungiso lwesiqhelo kunye noxakeka kuyimfuneko ukwahlulahlula iiphaneli kwicala le-AC, yiyo ke loo nto, isixhobo esisebenza sodwa esizimeleyo sibekwa phakathi kweepaneli kunye negalelo le-inverter. Olo tshintsho lubizwa ngokuba yi-DC isolator kuba ibonelela ngokwahlulwa kwe-DC phakathi kweepaneli ze-photovoltaic kunye nayo yonke inkqubo.

Olu lutshintsho olubalulekileyo lokhuseleko kwaye ugunyazisiwe kwinkqubo nganye yamandla e-photovoltaic ngokwe-IEC 60364-7-712. Imfuno ehambelana neBritane ivela kwi-BS7671-Icandelo 712.537.2.1.1, ethi "Ukuvumela ukugcinwa kwesiguquli se-PV, iindlela zokwahlula isiguquli se-PV kwicala le-DC kwaye icala le-AC kufuneka libonelelwe". Ukucaciswa kwezahlukanisi ze-DC uqobo kunikwe "Isikhokelo soFakelo lweeNkqubo ze-PV", icandelo 2.1.12 (uHlelo 2).
