Ihinduka rya WTIS izuba DC ni igikoresho gikoreshwa muri sisitemu ya Photovoltaque (PV) kugirango itandukane DC yinjira mumirasire y'izuba. Ubusanzwe yashyizwe mubisanduku bihuza, ni agasanduku gahuza imirasire y'izuba hamwe.Ihinduramiterere rya DC rirashobora guhagarika amashanyarazi ya DC mugihe cyihutirwa cyangwa kubungabunga, bikarinda umutekano wa sisitemu yifoto. Yashizweho kugirango ikore amashanyarazi menshi ya DC hamwe nubu bigaragazwa nizuba.Imikorere yizuba DC izunguruka zirimo:Imiterere irwanya ikirere kandi iramba: Ihinduramatwara yagenewe kwishyiriraho hanze kandi irashobora kwihanganira ibihe bibi.Bipolar switch: Ifite inkingi ebyiri kandi irashobora icyarimwe guhagarika imiyoboro myiza kandi mibi ya DC, ikemeza ko sisitemu yonyine.Igikoresho gifunga: Ihindura irashobora kugira ikiganza gifunga kugirango wirinde kwinjira cyangwa gukora impanuka.Ikimenyetso kigaragara: Abahindura bamwe bafite urumuri rwerekana urumuri rwerekana imiterere ya switch (kuri / kuzimya).Kubahiriza ibipimo byumutekano: Guhindura bigomba kubahiriza ibipimo byumutekano bijyanye, nka IEC 60947-3, kugirango bikore neza.
