Imibuzo ebuzwa qho

Ngaba ndingasebenzisa iiphaneli ezivela kwiimpawu ezahlukeneyo ezine-microinverter efanayo?

Ngelixa ngokobuchwephesha kunokwenzeka ukuba iinkcukacha zombane ziyahambelana, oku akukhuthazwa. Ukwahluka kwentsebenzo phakathi kweempawu kunokudala ukungalingani kunye nokunciphisa ukusebenza kakuhle ngokubanzi. Kukhethwa ukuba sebenzisa iiphaneli ezifanayo ukuqinisekisa ukusebenza ngokufanelekileyo.

Kwenzeka ntoni ukuba ndigqithise amandla amakhulu e-microinverter?

Ukugqithisa kwamandla kubangela ukusika: i-microinverter inciphisa imveliso yayo kumandla ayo alinganisiweyo, ilahlekelwa amandla amaninzi. Le meko, eyamkelekileyo ngamaxesha athile (iincopho zemveliso), iba yingxaki ukuba iyazingisa, ibangela ukutshisa kakhulu kunye nokunciphisa ubomi.

Ndikuqinisekisa njani ukuhambelana kwezinto esele zithengiwe?

Jongana neenkcukacha zobugcisa zesixhobo sakho kwaye uqinisekise ukuba amandla ombane aphezulu kwiphaneli yakho (Vmp) ayawa ngaphakathi koluhlu lweMPPT yemicroinverter yakho. Kwakhona qinisekisa ukuba i-short circuit current (Isc) yephaneli ihlala ingaphantsi I-microinverter ephezulu exhaswayo ngoku.

Ngaba iimeko zemozulu zichaphazela ukuhambelana?

Ewe, ngokubalulekileyo. Amaqondo obushushu aphezulu aguqula iimpawu zombane: ukubanda konyusa amandla ombane ngelixa ubushushu iyayinciphisa. Ubalo lokuhambelana kufuneka ludibanise ubuncinci bommandla wakho kunye namaqondo obushushu aphezulu ukuze uphephe ukungasebenzi kakuhle.

Ngaba iphaneli yelanga inokuyonakalisa i-microinverter engahambelaniyo?

Ngokuqinisekileyo. I-voltage egqithisileyo (iphaneli enkulu) inokonakalisa iisekethe ze-microinverter input. Ngokuchaseneyo, ukugqithisa okwangoku kunokubangela ubushushu obugqithisileyo kwaye kubangele ukukhuselwa, okanye ukonakalisa ngokusisigxina izixhobo. Ukuhambelana akunjalo ukukhetha kodwa kubalulekile kukhuseleko.

Ngaba zikhona iiadaptha zokwenza amacandelo angahambelaniyo ahambelane?

Akukho ziadaptha zithembekileyo zikhoyo ukulungisa amandla ombane asisiseko okanye ukungahambelani kwamandla. Izisombululo zokulungisa ngokubanzi lubeka esichengeni ukhuseleko kunye nokusebenza.
