Inkwenkwe ESSA0100B-0215<\/a><\/strong> sisikrini sokuqala esinengqiqo xa umsebenzi ofunekayo wokutshaja ibhetri uhlala ungaphakathi kwi-100 kW kwaye amandla agqithisileyo osuku angena kumda we-SOC oqinisekisiweyo. Ukuba isikhululo sikhiqiza ngokuphindaphindiweyo i-120 kW engaphezulu kunoko kusetyenziswa liziko, ikhabhinethi isenokutshaja nge-100 kW, kodwa i-20 kW eseleyo idinga indawo ecacisiweyo: ukuthunyelwa ngaphandle okuvumelekileyo, ukuncitshiswa kwe-PV okanye umthwalo ovunyiweyo notshintshayo.

I-PV eseluphahleni ivelisa i-95 kW ngaphezulu kwemfuno yendawo, kodwa ukulungiswa kobusuku kushiye ibhetri ikufuphi nomlinganiselo wayo ophezulu wamandla. Ngo-1:00 emva kwemini ibhetri izele kwaye umlawuli wesikhululo unciphisa umbane we-PV. Ukunqanda incopho yasemva kwemini ke kusebenzisa inxalenye yamandla agciniweyo, ngelixa ugcino olukhuselweyo luthatha enye inxalenye. Ngo-5:30 p.m. kusale amandla asetyenziswayo ambalwa kakhulu ukufikelela kwinjongo yangokuhlwa epheleleyo.
