Chitetezo cha makina a solar PV chinafotokoza malo ndi malo, kuyambira pa cholumikizira cha module kupita ku grid meter. Zipangizo zisanu ndi chimodzi, zotsatiridwa ndi IEC, zokhala ndi manambala enieni a kukula.

Chotsekera cha RCBO cholembedwa kuti Type AC chaletsedwa ku Australia kuyambira 2023 ndipo chaletsedwa ku UK kuyambira 2022. Yang'anani mipiringidzo 5 musanatchule kapena kugula.

Kuyerekeza kwa RCCB ndi RCBO ndi MCB pa ntchito yoyendera, malo a panelo, mtengo ndi miyezo ya IEC. Onani chipangizo chomwe dera lililonse limafunikiradi, kuphatikiza tebulo la masekondi 60.

Choteteza magetsi ochulukirapo ndi ocheperako chimachepetsa mphamvu pasanathe sekondi imodzi pamene magetsi akutuluka pawindo lanu lokhazikika. Yerekezerani mitundu ya DIN-rail, socket ndi relay, komanso ma setting tips.

Mitundu ya ma relay omwe afotokozedwa: yerekezerani ma relay amagetsi, olimba, a bango, ndi oteteza, kuphatikiza ma contact a SPST/SPDT, kuti musankhe yoyenera mwachangu.

Relay vs contactor: contactors amasinthasintha katundu kupitirira 15A, relay imakhala pansi pa 10A. Yerekezerani ma ratings, mawaya, ndi mtengo musanagule. Onani kufotokozedwa kwathunthu.

Dziwani tanthauzo la contactor, momwe imagwirira ntchito, kusiyana kwa AC/DC, ma diagram, ndi zosankha za zinthu za Tomzn kuti muwongolere bwino galimoto.

Phunzirani momwe mungayikitsire chipangizo choteteza mafunde pogwiritsa ntchito njira zotetezera mapanelo, kulumikiza mawaya, kuyika pansi, kuyesa, ndi kuthetsa mavuto.

Dziwani tanthauzo la Molded Case Circuit Breaker. Werengani malangizo athu abwino kwambiri okhudza zinthu za MCCB, momwe zimagwiritsidwira ntchito, komanso momwe zimafananira ndi MCB mosamala.

Kudziwa bwino kuthetsa mavuto, kuyesa & kusintha ma circuit breaker. Dziwani mitundu yapamwamba ya ma panel ndi momwe mungabwezeretsere kapena kusintha ma breaker box anu mosamala.
