Ntụle nke nnyefe DC jikọtara ma ọ bụ AC jikọtara ọnụ
Mgbe ị na-enyocha usoro nchekwa anyanwụ + jikọtara DC, ụfọdụ isi ihe kwesịrị ịtụle. Isi uru dị na sistemụ nchekwa anyanwụ + ike DC jikọtara ọnụ bụ:
• Mbelata ọnụahịa akụrụngwa site n'ibelata ọnụ ahịa nke ibuga inverters, mgba ọkụ ọkụ nke ọkara, na akụrụngwa ndị ọzọ.
• Na-enye ohere ka usoro ike anyanwụ weghara ike anyanwụ na-efunarị ma ọ bụ mebie ya mgbe ihe ibu inverter karịrị 1, na-emepụta ego ndị ọzọ.
• Ọ nwere ike ijikọ nchekwa anyanwụ + ike n'otu nkwekọrịta ịzụta ike (PPA).
Ọdịmma nke sistemụ nchekwa anyanwụ + ike DC jikọtara ọnụ bụ:
N'iji ya tụnyere AC-ejikọta anyanwụ-gbakwunyere-nchekwa usoro, DC-ejikọta anyanwụ-gbakwunyere-nchekwa usoro nwere obere ọrụ mgbanwe n'ihi na ha na-ejedebeghị site inverter ike mgbe ike njikọ dị ukwuu.
