I-Photovoltaic inverter (i-PV inverter okanye inverter yelanga) inokuguqula umbane oguquguqukayo we-DC oveliswa yi-photovoltaic (PV) iiphaneli zelanga zibe yi-inverter ene-alternating current (AC) frequency frequency of mains frequency, enokubuyiselwa kwinkqubo yothumelo lwamandla orhwebo, okanye inikezelwe kusetyenziso lwegridi yegridi.I-Photovoltaic inverter yenye ye-balance balance of system (BOS) kwi-photovoltaic array system, enokusetyenziswa kunye nezixhobo zombane jikelele ze-AC.Abaguquli belanga banemisebenzi ekhethekileyo ye-photovoltaic arrays, njengokulandelela indawo yamandla aphezulu kunye nokukhuselwa kwesiqithi.
Iziguquli zelanga zinokwahlulwa zibe ngamacandelo amathathu alandelayo:
1. Ii-inverters ezizimeleyo: ezisetyenziswa kwiinkqubo ezizimeleyo, i-photovoltaic array ihlawulisa ibhetri, kwaye i-inverter isebenzisa i-voltage ye-DC yebhetri njengomthombo wamandla.Uninzi lwee-inverters ezizimeleyo zikwabandakanya iitshaja zebhetri ezinokutshaja ibhetri kumandla e-AC.Ngokuqhelekileyo, ii-inverters ezinjalo aziyichukumisi igridi kwaye ngoko ayifuni ukukhuselwa kwesiqithi.
2. Ii-inverters ze-Grid-tie: I-voltage ye-output ye-inverter inokubuyiselwa kumbane we-AC yorhwebo, ngoko ke i-export sine wave kufuneka ifane nesigaba, i-frequency kunye ne-voltage yokunikezelwa kwamandla.I-inverter edibeneyo yegridi inoyilo lokhuseleko, kwaye ukuba ayixhunyiwe kumandla ombane, umphumo uya kuvalwa ngokuzenzekelayo.Ukuba umbane wegridi awuphumeleli, i-inverter edibeneyo yegridi ayinayo umsebenzi wokuxhasa ukunikezelwa kwamandla.
3. Ii-inverters ezigcina ibhetri (Ii-inverters ezigcina ibhetri) ziziguquli ezikhethekileyo ezisebenzisa iibhetri njengomthombo wazo wamandla kwaye zisebenzisana netshaja yebhetri ukutshaja iibhetri.Ukuba kukho amandla amaninzi kakhulu, iya kutshajwa kwakhona kumthombo wamandla we-AC.isiphelo.Olu hlobo lwe-inverter lunokubonelela ngamandla e-AC kumthwalo ochaziweyo xa amandla egridi engaphumeleli, ngoko ke kufuneka abe nomsebenzi wokukhusela umphumo.
