Umhlahlandlela Ophelele Wokuhlukaniswa Kwesitoreji Se-PV-Storage System Nokucushwa

Isistimu ye-Photovoltaic (PV) -Storage -Torage Umgomo wayo ukufezekisa ukwaneliseka kwamandla, ukunciphisa izindleko zamandla, ukuphuma kwekhabhoni ephansi, futhi uthuthukise ukuthembeka kwamandla. Ilungiselela uhlelo lokugcina indawo yokugcina i-PV kuyinqubo ebanzi edinga ukucubungula ngokucophelela kwezinto ezahlukahlukene ukuqinisekisa ukusebenza kahle nokuzinzile.

I. Ukubuka konke kwezinhlelo zokugcina zokugcina ze-PV

Ngaphambi kokuqala ukusetha kohlelo, kubalulekile ukukala ukumelana nokufakwa kwe-DC kokufakwa kwe-DC phakathi kwe-PV ARRAY ARRAY WOKUTS OFT ORP OTPT NOROT. Uma ukumelana kungaphansi kwe-U ... / 30mA (U ... umele i-voltage ephezulu yokuphuma ye-PV Aray), kufanele kuthathwe izinyathelo ezingeziwe noma izindlela zokufakelwa.

Imisebenzi eyinhloko yezinhlelo zokugcina zokuhlala ze-PV zifaka:

• Ukuzisebenzisa: Sebenzisa amandla elanga ukuze uhlangane nezidingo zamandla ezindlu.
