Kuzvimiririra kwevamwe vagadziri, ma microinverters anoratidzira masisitimu ekutarisa data. Kana data rikagadziriswa kune ac mitsara kuburikidza nema microinverters, chishandiso chekudzivirira chinofanira kupihwa pane akapatsanurwa ekugununura zvikamu (dhata rekutengesa / dhizaini dhizaini). Izvo zvinoshandawo kune zvinongedzo zvekubatana neepasi pemvura bhazi masisitimu uye yavo magetsi magetsi (eg Ethernet, ISDN).

Solar magetsi ekugadzira masisitimu chikamu chakakosha chemagetsi ezuva ranhasi. Ivo vanofanirwa kuve vakagadzirirwa nemagetsi akakwana azvino uye vafambi vanosunga, nokudaro vachivimbisa kushanda kwenguva refu-kusine mhaka kweaya manyuko emagetsi.
