Mitundu ya ma inverters osungira mphamvu m'nyumba
Ma inverters osungira mphamvu zogona amatha kugawidwa m'njira ziwiri zaukadaulo: kuphatikiza kwa DC ndi kuphatikiza kwa AC.Mu dongosolo losungiramo photovoltaic, zigawo zosiyanasiyana monga ma solar panels ndi galasi la PV, olamulira, ma inverters a dzuwa, mabatire, katundu (zida zamagetsi), ndi zipangizo zina zimagwira ntchito pamodzi.Kulumikizana kwa AC kapena DC kumatanthawuza momwe ma solar amalumikizidwa ndi malo osungira mphamvu kapena ma batri.Kulumikizana pakati pa ma module a dzuwa ndi mabatire a ESS kungakhale AC kapena DC.Ngakhale mabwalo ambiri amagetsi amagwiritsa ntchito magetsi olunjika (DC), ma module a solar amapanga magetsi, ndipo mabatire adzuwa akunyumba amasunga magetsi, zida zambiri zimafunikira magetsi osinthira (AC) kuti agwire ntchito.
Mu makina osungira mphamvu a dzuwa osakanizidwa, magetsi omwe amapangidwa ndi magetsi a dzuwa amasungidwa mu paketi ya batri kudzera mwa wolamulira.Kuphatikiza apo, gululi imathanso kulipiritsa batire kudzera pa chosinthira cha bidirectional DC-AC.Malo osinthira mphamvu ali kumapeto kwa batri la DC BESS.Masana, kupanga magetsi a photovoltaic poyamba kumapereka katundu (zogulitsa zamagetsi zapakhomo) ndiyeno kulipiritsa batire kudzera pa MPPT solar controller.Dongosolo losungiramo mphamvu limalumikizidwa ndi gridi ya boma, kulola kuti mphamvu yochulukirapo idyetsedwe mu gridi.Usiku, batire imatuluka kuti ipereke mphamvu ku katundu, ndi kuchepa kulikonse komwe kumawonjezeredwa ndi grid.Ndizofunikira kudziwa kuti mabatire a lithiamu amangopereka mphamvu kuzinthu zakunja ndipo sangathe kugwiritsidwa ntchito pamagetsi olumikizidwa ndi grid pomwe gululi yamagetsi yatha.Nthawi zina mphamvu yolemetsa imaposa mphamvu ya PV, ma gridi ndi makina osungira batire a solar amatha kupereka mphamvu pakunyamula nthawi imodzi.Batire imagwira ntchito yofunikira pakulinganiza mphamvu zamakina chifukwa cha kusinthasintha kwa kupanga magetsi a photovoltaic komanso kugwiritsa ntchito mphamvu zamagetsi.Kuphatikiza apo, makinawa amalola ogwiritsa ntchito kukhazikitsa nthawi yolipirira ndi kutulutsa kuti akwaniritse zofuna zawo zamagetsi.
Momwe DC Coupled Energy Storage System Imagwirira Ntchito
Hybrid photovoltaic + mphamvu yosungirako mphamvu
Inverter ya solar hybrid imaphatikiza magwiridwe antchito a gridi kuti apititse patsogolo kuyendetsa bwino.Mosiyana ndi ma inverter a pa-grid, omwe amangoyimitsa makina a solar pazifukwa zachitetezo, ma inverter osakanizidwa amapatsa ogwiritsa ntchito mphamvu yogwiritsa ntchito mphamvu ngakhale kuzimitsidwa, chifukwa amatha kugwiritsa ntchito gridi yonse ndikulumikizidwa ndi gululi.Ubwino wama hybrid inverters ndi kuwunikira kosavuta komwe amapereka.Ogwiritsa ntchito amatha kupeza mosavuta deta yofunikira monga magwiridwe antchito ndi kupanga mphamvu kudzera pagawo la inverter kapena zida zolumikizidwa zanzeru.Pazochitika zomwe dongosololi limaphatikizapo ma inverters awiri, aliyense ayenera kuyang'aniridwa mosiyana.Kuphatikizana kwa DC kumagwiritsidwa ntchito mu ma inverters osakanizidwa kuti achepetse kutayika pakutembenuka kwa AC-DC.Kuthamanga kwa batri ndi kuphatikiza kwa DC kumatha kufika pafupifupi 95-99%, poyerekeza ndi 90% ndi AC coupling.
Kuphatikiza apo, ma hybrid inverters ndiokwera mtengo, ophatikizika, komanso osavuta kukhazikitsa.Kuyika inverter yatsopano yosakanizidwa yokhala ndi mabatire ophatikizana a DC kungakhale kotsika mtengo kuposa kubwezeretsanso mabatire ophatikizana a AC mudongosolo lomwe lilipo.Olamulira a dzuwa omwe amagwiritsidwa ntchito mu ma inverters osakanizidwa ndi otsika mtengo kusiyana ndi ma grid-tied inverters, pamene zosinthira zosinthira zimakhala zotsika mtengo kuposa makabati ogawa magetsi.DC coupling solar inverter imathanso kuphatikizira ntchito zowongolera ndi ma inverter mu makina amodzi, zomwe zimapangitsa kuti pakhale ndalama zowonjezera pazida ndi kuyika.Kukwera mtengo kwa DC coupling system kumawonekera makamaka m'makina ang'onoang'ono ndi apakatikati osungira mphamvu zamagetsi.Mapangidwe amtundu wa ma inverters osakanizidwa amalola kuwonjezera kosavuta kwa zigawo ndi zowongolera, ndi mwayi wophatikizira zida zowonjezera pogwiritsa ntchito chowongolera cha solar cha DC chotsika mtengo.Ma Hybrid inverters amapangidwanso kuti azithandizira kuphatikiza kosungirako nthawi iliyonse, kufewetsa njira yowonjezeramo batire mapaketi.Dongosolo la hybrid inverter limadziwika ndi kukula kwake kophatikizika, kugwiritsa ntchito mabatire othamanga kwambiri, komanso kukula kwa chingwe, zomwe zimapangitsa kuti pakhale kutayika kwathunthu.
