Ukukhetha i-inverter efanelekileyo kufuna uqwalaselo olucokisekileyo lokusebenza kakuhle, iimfuno zamandla, kunye nesicelo-impawu ezithile. Umzekelo, ulungelelwaniso ngeUkusebenza kwe-95%.bagqwese kwiimeko zamandla aphantsi, ngelixa abo bane-85% besebenza ngokufanelekileyo bahambelana neemfuno zamandla aphezulu.

Ingaba amandla ombane welanga okanye ukudibanisa negridi, ukukhetha i-inverter efanelekileyo kuqinisekisa ukuthembeka nokusebenza kakuhle.

Biza ngaphandle: I-DC ukuya kwi-AC uguqulo lwamandla ayonto nje inkqubo yobugcisa; lisango kwizisombululo zamandla azinzileyo. Thatha ixesha lokuvavanya iimfuno zakho kwaye ukhethe i-inverter ehambelana neenjongo zakho.

FAQ

Yintoni umahluko phakathi kwamaza e-sine ecocekileyo kunye neziguquli eziguquliweyo ze-sine wave?

Iziguquli zoguqulo zamaza e-sine zivelisa amandla agudileyo, afana negridi ye-AC, alungele izinto zombane ezibuthathaka. Iziguquli ze-sine eziguquliweyo zivelisa amandla anyusiweyo, anokubangela imiba ngezixhobo ezithile. Ndincoma ii-inverters ezicocekileyo ze-sine kwizicelo ezibalulekileyo zokuqinisekisa ukuhambelana nokukhusela izixhobo zakho.

Ndiwubala njani ubungakanani be-inverter efanelekileyo kwiimfuno zam?

Yongeza i-wattage yazo zonke izixhobo oceba ukuzidibanisa. Bandakanya i-20-30% yesithinteli sotyando. Umzekelo, ukuba izixhobo zakho zombane zidinga i-1,500 watts, khetha i-inverter elinganiselwe ubuncinci be-2,000 watts. Oku kuthintela ukugqithiswa kunye nokuqinisekisa ukusebenza okuthembekileyo.

Ngaba ndingasebenzisa i-inverter ngeepaneli zam zelanga?

Ewe, kodwa qinisekisa ukuba i-inverter ihambelana nombane wesixhobo sakho selanga kunye nokukhutshwa kwamandla. Ndincoma ii-inverters ngeteknoloji ye-Maximum Power Point Tracking (MPPT) ukwenzela ukutsalwa kwamandla aphezulu. Olu phawu lukhulisa ukusebenza kakuhle, ngakumbi phantsi kweemeko ezahlukeneyo zokukhanya kwelanga.

Ngaba ii-inverters zikhuselekile ukusetyenziswa kwindawo ezifumileyo okanye ngaphandle?

Iziguquli ezenzelwe ukusetyenziswa ngaphandle zihlala zinemilinganiselo ephezulu yokhuseleko lokungena (IP), njenge-IP65, ukukhusela umonakalo wokufuma. Ndicebisa ukuzifaka kwiindawo ezinomthunzi, ezinomoya kunye nokukhetha iimodeli ezineentsimbi eziqinileyo zokuqina kwiimeko ezinzima.

Ndingayiphucula njani inkqubo yam yoguqulo?

Khetha i-inverter enomgangatho ophezulu wokusebenza, ngokufanelekileyo ngaphezulu kwe-95%. Ukugcinwa rhoqo, okufana nokucoca iminyango kunye nokuqinisekisa ukuhamba komoya okufanelekileyo, kunciphisa ilahleko yamandla. Iimpawu eziphambili ezifana neteknoloji yeMPPT iphinda ikhulise ukusebenza, ngakumbi kwiinkqubo zamandla elanga.
