Inverter ndi ubongo ndi mtima wa makina opangira magetsi a photovoltaic. Pakupanga magetsi a photovoltaic a solar, mphamvu yopangidwa ndi makina opangira magetsi a photovoltaic ndi mphamvu ya DC. Komabe, katundu wambiri amafunika mphamvu ya AC, ndipo makina opangira magetsi a DC ali ndi zolepheretsa zazikulu ndipo ndizovuta kusintha magetsi. , kuchuluka kwa ntchito yonyamula katundu kumakhala kochepa, kupatulapo magetsi apadera, ma inverter amafunika kusintha mphamvu ya DC kukhala mphamvu ya AC. Inverter ya photovoltaic ndi mtima wa makina opangira magetsi a photovoltaic a solar, omwe amasintha mphamvu yolunjika yopangidwa ndi ma module a photovoltaic kukhala mphamvu yosinthana, ndikuitumiza ku katundu wapafupi kapena gridi, ndipo ndi chipangizo chamagetsi chamagetsi chokhala ndi ntchito zotetezera.
Chosinthira mphamvu cha solar chimapangidwa makamaka ndi ma module amphamvu, ma control circuit board, ma circuit breaker, ma filter, ma reactor, ma transformer, ma contactor ndi makabati. Njira yopangirayi imaphatikizapo kukonza zida zamagetsi, kusonkhanitsa makina kwathunthu, kuyesa ndi kuyika makina kwathunthu. Kukula kwake kumadalira chitukuko cha ukadaulo wamagetsi amphamvu, ukadaulo wa zida za semiconductor ndi ukadaulo wamakono wowongolera.
Kwa ma inverters a solar, kukonza mphamvu yosinthira magetsi ndi nkhani yosatha, koma pamene mphamvu ya makina ikukwera kwambiri, pafupifupi 100%, kusintha kowonjezereka kwa mphamvu kudzaphatikizidwa ndi magwiridwe antchito otsika mtengo. Chifukwa chake, momwe mungasungire bwino. Kugwiritsa ntchito bwino kwambiri, komanso kusunga mpikisano wabwino pamitengo, kudzakhala nkhani yofunika kwambiri pakadali pano.
Poyerekeza ndi khama lokonza mphamvu ya inverter, momwe mungakonzere mphamvu ya inverter yonse pang'onopang'ono ikukhala nkhani ina yofunika kwambiri pa mphamvu ya dzuwa. Mu solar array, pamene mthunzi wa dera la 2%-3% umawonekera, kwa inverter yomwe imagwiritsa ntchito MPPT function, mphamvu yotulutsa ya system panthawiyi ikhoza kutsika ndi pafupifupi 20% pamene mphamvu yotulutsa ili yofooka. Kuti muzolowere bwino mkhalidwe ngati uwu, ndi njira yothandiza kwambiri kugwiritsa ntchito MPPT imodzi kapena zingapo zowongolera MPPT pa ma solar module amodzi kapena ochepa.
Popeza makina osinthira magetsi ali mumkhalidwe wolumikizidwa ndi gridi, kutuluka kwa makinawo pansi kumabweretsa mavuto akulu achitetezo; kuphatikiza apo, kuti makinawo azitha kugwira bwino ntchito, ma solar array ambiri adzalumikizidwa motsatizana kuti apange magetsi amphamvu a DC output; Chifukwa cha zochitika zachilendo pakati pa ma electrode, n'zosavuta kupanga DC arc. Chifukwa cha magetsi amphamvu a DC, n'zovuta kwambiri kuzimitsa arc, ndipo n'zosavuta kuyambitsa moto. Chifukwa cha kugwiritsa ntchito makina osinthira magetsi a solar, nkhani ya chitetezo cha makina idzakhalanso gawo lofunikira paukadaulo wa inverter.
