Sebakeng sa matla a macha, li-inverters tsa photovoltaic le li-inverters tsa polokelo ea matla ke lisebelisoa tsa bohlokoa, 'me li bapala karolo ea bohlokoa bophelong ba rona. Empa hantle-ntle phapang pakeng tsa tse peli ke efe? Re tla etsa tlhahlobo e tebileng ea li-inverters tsena tse peli ho tsoa likarolong tsa sebopeho, ts'ebetso, maemo a ts'ebeliso, joalo-joalo.
01 Phapang ea sebopeho
Pele ho tsohle, ha e le hantle, inverter ke sesebelisoa se fetolang matla a DC hore e be matla a AC. E sebelisa mekhoa ea ho fetola lisebelisoa tsa semiconductor (tse kang li-transistors tsa tšimo kapa li-thyristors, joalo-joalo) ho laola motlakase oa motlakase le oa hona joale ka ho fetoha ka potlako, ka hona ho finyella phetoho ho tloha ho DC ho ea ho AC.

02 Likarolo
Ha e le hantle, inverter ea photovoltaic e shebana haholo le ho fetola matla a DC a hlahisoang ke liphanele tsa letsatsi la photovoltaic hore e be matla a AC bakeng sa tšebeliso ea marang-rang kapa lisebelisoa tsa motlakase. E ntlafatsa matla a tlhahiso ea matla a letsatsi la photovoltaic ka lipotoloho tse ka hare le li-module tsa taolo, e etsa letoto la lits'ebetso ho matla a DC a hlahisoang ke liphanele tsa photovoltaic, 'me qetellong e hlahisa matla a AC a finyellang litlhoko tsa marang-rang a matla.
Li-inverters tsa polokelo ea matla li ela hloko haholoanyane phetoho ea litsela tse peli le tsamaiso e bohlale ea matla a motlakase. Ha e fetole matla a DC feela hore e be matla a AC, empa hape e fetola matla a AC hore e be matla a DC bakeng sa polokelo. Ntle le ho hlokomela phetoho ea DC ho AC, e boetse e ts'ehetsa khokahano ea BMS / EMS, taolo ea maemo a lihlopha, ho eketseha ha tefiso le bokhoni ba ho tsoa, taolo e ikemetseng ea sebaka sa ho kuta le ho tlatsa phula, le kemiso e bohlale ea litefiso le ts'ebetso ea ts'ebetso ea polokelo ea matla. tsamaiso.
03 Maemo a kopo
Mabapi le maemo a ts'ebeliso, li-inverters tsa photovoltaic li sebelisoa haholo-holo mekhoeng ea ho hlahisa matla a letsatsi, joalo ka lisebelisoa tsa photovoltaic tsa malapa, merero ea photovoltaic ea indasteri le ea khoebo, le liteishene tse kholo tsa matla a fatše. Mosebetsi oa eona o ka sehloohong ke ho fetolela matla a DC a sistimi ea ho fehla matla a letsatsi hore e be matla a AC le ho a kopanya ho grid.

Li-inverters tsa polokelo ea matla li shebane haholo le lits'ebetso tsa lits'ebetso tsa polokelo ea matla a electrochemical, joalo ka liteishene tsa matla a polokelo ea matla, mofuta o bohareng kapa oa likhoele, maemo a indasteri, a khoebo le a malapa. Maemong ana, li-inverters tsa polokelo ea matla li fihlella ts'ebeliso e nepahetseng le polokelo ea matla a tsosolositsoeng ka ho laola ka bohlale ts'ebetso ea ho tjhaja le ho lahla, ho fana ka tšehetso e tsitsitseng le e tšepahalang ea matla bakeng sa maemo a fapaneng a ts'ebeliso.
04 Setšoantšo sa sistimi ea polokelo ea matla ea motlakase
Lintlha tse tloaelehileng le liphapangMabapi le lintlha tse tloaelehileng, ka bobeli ke lisebelisoa tsa elektronike tsa matla, tse sebelisetsoang ho fetola le ho laola matla a motlakase ho finyella ts'ebetso e tsitsitseng ea tsamaiso ea matla. Kaofela ba hloka ho fihlela litekanyetso tse itseng tsa polokeho ea motlakase ho netefatsa ts'ebetso e bolokehileng ea lisebelisoa. Ho phaella moo, kaha li-inverters tsa polokelo ea matla li hloka mekhoa e kopanetsoeng ea tsamaiso ea betri, litšenyehelo tsa tsona li batla li phahame. Mosebetsi oa li-inverters tsa photovoltaic o batla o le bonolo, kahoo litšenyehelo hangata li tlaase. Ka nako e ts'oanang, li-inverters tsa polokelo ea matla le tsona li na le litlhoko tse phahameng tsa polokeho. Ntle le ho kopana le litekanyetso tsa mantlha tsa polokeho ea motlakase, polokeho ea sistimi ea taolo ea betri le mehato ea ts'ireletso ha betri e hloleha le tsona li hloka ho nahanoa.

Qetellong, ho na le phapang e hlakileng pakeng tsa li-inverters tsa photovoltaic le li-inverters tsa polokelo ea matla mabapi le melao-motheo, maemo a kopo, tlhahiso ea matla, litšenyehelo le polokeho. Ha ho tluoa lits'ebetsong tsa lefats'e la 'nete, ho bohlokoa ho khetha lisebelisoa tse nepahetseng ho latela litlhoko le maemo a itseng. Ho sebelisana 'moho le AMENSOLAR, joalo ka moetsi ea ka sehloohong oa motlakase oa letsatsi, ho netefatsa phihlello ea litharollo tse nepahetseng, ho hohela barekisi ba bangata ho kena marang-rang a rona.
