Ne bwe kiba nti data ya pulojekiti eyeetaagisa, ebiteberezebwa ebitonotono ebya bulijjo bikyayinza okukyusakyusa okusalawo kw’enzimba.
"DC Coupling Bulijjo Esinga Okukola Ennungi".
DC coupling esobola okukendeeza ku kufiirwa kw’okukyusa ku kkubo lya PV-to-battery, naye obulungi bwonna era businziira ku ngeri y’okukola, ensalosalo y’okupima, n’enkozesa ey’obuyambi. Ekkubo erimpi ery’okukyusa si bulijjo livvuunula mu muwendo gwa pulojekiti ogw’oku ntikko.
"Ebitundu Ebitono Bulijjo Bitegeeza Ssente za Pulojekiti Entono".
Okugabana inverter kiyinza okukendeeza ku kuddiŋŋana kw’ebyuma, naye ssente zonna eza pulojekiti era zirimu okukyusa DC/DC, okukuuma, okufuga, okutandika okukola, n’okukyusakyusa mu biseera eby’omu maaso. Omuwendo gw’ebyuma ogusookerwako ogwa wansi guyinza okuleeta ekkomo erinywevu mu kukola oba okugaziya oluvannyuma.
"AC Coupling Ya Pulojekiti Za Solar Eziriwo Zokka".
AC coupling ya bulijjo mu retrofits, naye era esobola okuweereza pulojekiti empya ezeetaaga flexible grid charging, independent dispatch, oba modular expansion. Omutendera gwa pulojekiti nsonga emu mu nnyingi-tegusalawo nzimba yokka.
Okugeraageranya kulaga nti tewali nsengeka yonna esaana kulondebwa okuva mu nsonga emu.
AC coupling okutwalira awamu egaba obwetwaze obusingawo ne modularity. DC coupling esobola okukendeeza ku PV-to-battery path era n'okukozesa obulungi amaanyi agasaliddwa oba obusobozi bw'okuyunga okugabana.
Okulonda okutuufu kuva mu kifaananyi kya pulojekiti mu bujjuvu: entandikwa, ekkubo ly’amasoboza, ebyetaago by’emirimu, okuyungibwa ku mudumu, n’enteekateeka y’okugaziya. Ensonga zino ettaano zirina okwekenneenya wamu nga enzimba tennamalirizibwa.
