Momwe mungawonjezere mabatire ku solar yomangidwa ndi grid - DC Coupling

Pakukhazikitsa kophatikizana ndi DC, gulu la solar limalumikizana mwachindunji ndi banki ya batri kudzera pa chowongolera. Kukonzekera kumeneku kumakhala kofanana ndi makina a off-grid koma amathanso kusinthidwa kuti akhale omangika pogwiritsa ntchito 600-volt string inverter.

600V charger controller imathandizira kubweza makina omangidwa ndi gridi okhala ndi mabatire ndipo amatha kuphatikizidwa ndi malo athu aliwonse opangira mawaya omwe alibe chowongolera. Imayikidwa pakati pa PV array yomwe ilipo ndi inverter yomangidwa ndi gridi, yokhala ndi chosinthira chamanja chosinthira pakati pa grid-tie ndi njira zakunja. Komabe, ilibe dongosolo, imafunikira kusinthana kwakuthupi kuti muyambitse kulipiritsa batire.

Ngakhale inverter yochokera ku batri imathabe kupangira zida zofunika pawokha, gulu la PV silidzalipira mabatire mpaka chosinthiracho chizitsegulidwa pamanja. Izi zimafunika kupezeka pamalopo kuti muyambe kulitcha solar, chifukwa kuyiwala kutero kungapangitse mabatire okhetsedwa opanda mphamvu ya solar.

Ubwino wa DC Coupling umaphatikizanso kugwirizanitsa ndi ma inverter osiyanasiyana otalikirapo ndi makulidwe a banki ya batri poyerekeza ndi kuphatikiza kwa AC. Komabe, kudalira kwake kosinthira pamanja kumatanthawuza kuti muyenera kukhalapo kuti muyambitse PV charging, kulephera zomwe makina anu aziperekabe mphamvu zosunga zobwezeretsera koma osabwezeretsanso solar.
