Njengoba umhlaba uqaphela kakhulu ukusetshenziswa kwamandla, ezinye izixazululo zamandla njenge-off-grid kanyeama-inverters ama-hybridzikhula ngokuthandwa.Lawa ma-inverter adlala indima ebalulekile ekuguquleni i-direct current (DC) ekhiqizwa imithombo yamandla avuselelekayo njengamaphaneli elanga noma izinjini zomoya zibe amandla ashintshashintshayo asebenzisekayo (AC) ukuze ahlangabezane nezidingo zethu zansuku zonke.Kodwa-ke, kubalulekile ukuqonda umehluko phakathi kwama-off-grid nama-hybrid inverters lapho unquma ukuthi yiluphi uhlelo olulungele izidingo zakho zamandla.
I-inverter engaphandle kwegridi
Njengoba igama liphakamisa, ama-inverter angaphandle kwegridi aklanyelwe ukusebenza ngokuzimela ngaphandle kwegridi.Zivame ukusetshenziswa ezindaweni ezikude lapho uxhumo lwegridi lulinganiselwe noma lungekho.Lawa ma-inverter anomthwalo wemfanelo wokuphatha amandla engeziwe akhiqizwa imithombo yamandla avuselelekayo futhi awagcine ebhange lebhethri ukuze asetshenziswe kamuva.
Isici esihlukanisayo se-off-grid inverters yikhono labo lokusebenza ngaphandle kwamandla angapheli avela kugridi.Baguqula amandla aqondile akhiqizwa ama-solar noma ama-turbines omoya abe amandla ashintshayo angasetshenziswa ngokuqondile ngezinto zasendlini noma agcinwe kumabhethri.Ama-inverter angaphandle kwegridi ngokuvamile aneshaja eyakhelwe ngaphakathi engashaja kabusha ibhange lebhethri uma amandla anele etholakala.
I-inverter ye-Hybrid
Ama-inverter amaHybrid, ngakolunye uhlangothi, anikela ngokungcono kakhulu kwemihlaba yomibili ngokuhlanganisa amandla angaphandle kwegridi nakumagridi.Asebenza ngendlela efanayo kuma-inverter angaphandle kwegridi kodwa anenzuzo eyengeziwe yokukwazi ukuxhuma kugridi.Lesi sici sinikeza ukuguquguquka kokudonsa amandla kugridi ngezikhathi zesidingo esikhulu noma lapho amandla avuselelekayo engakwazi ukuhlangabezana nezimfuneko zokulayisha.
Kuhlelo oluxubile, amandla asele akhiqizwa imithombo yamandla avuselelekayo agcinwa ebhethrini, njengasohlelweni olungekho kugridi.Nokho, lapho ibhethri liphansi noma amandla engeziwe edingeka, isiguquli esixubile sishintsha ngobuhlakani ukuze sidonse amandla kugridi.Ukwengeza, uma kunensada yamandla avuselelekayo, angathengiswa ngempumelelo abuyiselwe kugridi, okuvumela abanikazi bezindlu ukuthi bathole amakhredithi.
Umehluko omkhulu
1. Ukusebenza: Ama-inverter angaphandle kwegridi asebenza ngaphandle kwegridi futhi athembele ngokuphelele kumandla avuselelekayo namabhethri.Ama-inverter amaHybrid, ngakolunye uhlangothi, angasebenza ngaphandle kwegridi noma axhunywe kugridi uma kunesidingo.
2. Uxhumano Lwegridi: Iziguquli ezingaphandle kwegridi azixhunyiwe kugridi, kuyilapho iziguquli ezihlanganisiwe zinamandla okushintsha kalula phakathi kwamandla egridi namandla avuselelekayo.
3. Ukuguquguquka: Iziguquli ezihlanganisiwe zinikeza ukuguquguquka okukhulu ngokuvumela ukugcinwa kwamandla, ukuxhumeka kwegridi, kanye nekhono lokuthengisa amandla engeziwe emuva kugridi.
Ekuphetheni
Ukukhetha i-off-grid noma i-inverter ye-hybrid kuncike ezidingweni zakho ezithile zamandla nendawo.Ama-inverter angaphandle kwegridi alungele izindawo ezikude ezinokuxhumeka okulinganiselwe noma okungekho, okuqinisekisa ukuthuthukiswa okuzinzile.Ama-inverter amaHybrid, ngakolunye uhlangothi, asiza ukusetshenziswa kwamandla avuselelekayo kanye nokuxhumeka kwegridi ngezikhathi zokukhiqiza amandla anganele avuselelekayo.
Ngaphambi kokutshala imali ohlelweni lwe-inverter, thintana nochwepheshe ukuze ahlole izidingo zakho zamandla futhi aqonde imithetho yendawo mayelana noxhumo lwegridi kanye nezinzuzo zamandla avuselelekayo.Ukuqonda umehluko phakathi kwe-off-grid kanye nama-inverter ayi-hybrid kuzokusiza ukuthi ukhethe isixazululo esifanele sokuhlangabezana ngokuphumelelayo nezidingo zakho zamandla kuyilapho ukhuthaza ukusimama.
Uma unentshisekelo kuma-inverter angaphandle kwegridi, wamukelekile ukuthintana neRadiance kuFunda kabanzi.
