Kutaurirana kweBMS kweKubatanidzwa kweSolar Storage: Kuenderana kweCAN, RS485, uye Inverter Protocol

Sei Kutaurirana kweInverter Kuri Kukundikana Kwenzvimbo Yekutanga Kwekuvaka Nzvimbo Dzekuchengetera Solar

Taura nemunhu wese akaraira nzvimbo yekuchengetera simba rezuva uye uchanzwa imwe nyaya yakafanana: paki yakapasa bvunzo dzese pabhenji. Ma voltage emasero mukati me spec, kuenzana kushanda, dziviriro dzichibvira sezvaitarisirwa. Zvadaro panzvimbo yacho, inverter nebhatiri zvakaramba kutaura - kana zvakatoipa, vakataura, asi vakataura mamiriro asiri iwo echaji, vakaramba mirairo yekuchaja, kana kukanda makodhi ekukanganisa hapana aigona kutsanangura. Paki yakadzoka kumba. Purojekiti yakarasikirwa nevhiki.

Iyi haisi nyaya isingawanzoitiki. Ndiyo imwe yenyaya dzinonyanya kukundikana mumabasa ekuchengetera simba rezuva, uye nguva dzese chikonzero chacho chakafanana: BMS ine CAN port, asi isingataure zvinoenderana nezvinodiwa ne inverter. Kune yekuchengetedza, kutaurirana hakusi chinhu - ndiyo hwaro hwakavakirwa pahurongwa.

Nzira Nhatu — Zvinoitwa Neimwe Neimwe MuSystem Yekuchengetera Zvinhu

Kutaurirana kweBMS yekuchengetedza zuva kunowanzo shandisa nzira nhatu dzemuviri, imwe neimwe iine nzira dzakasiyana dzekufambisa. Kuziva kuti ndeipi nzira inobata danho rekutanga pakunyora zvirevo zvekutaurirana zvinobatsira:

Bhazi reCAN

Chinobatanidza bhatiri ne inverter panguva chaiyo. CAN inotakura mamiriro ekuchaja, miganhu yekuchaja nekuburitsa magetsi, miganhu yemagetsi, mireza yezvikanganiso, uye meseji dzekudzora dzakanangana neprotocol. Iyi ndiyo nzira iyo inverter inoshandisa kuti izive mashandisirwo ekuchaja nekuburitsa bhatiri zvakachengeteka. Kana CAN ikakundikana kana kutaura protocol isiriyo, system yese haina chainogona kushanda pairi.
