Mosebetsi oa Inverter Sistemeng ea Phanele ea Letsatsi
Inverter ke sesebelisoa sa motlakase se fetolang motlakase o tobileng (DC) o hlahisoang ke liphanele tsa letsatsi hore e be motlakase o fapanyetsanang (AC), o lumellang motlakase hore o sebelisoe ke lisebelisoa tsa lapeng kapa o fepeloe ka har'a gridi ea motlakase. Mesebetsi ea mantlha ea inverter tsamaisong ea phanele ea letsatsi e kenyelletsa:
1. Phetoho ea DC ho ea ho AC: Mosebetsi oa mantlha oa inverter ke ho fetolela motlakase o tobileng o hlahisoang ke liphanele tsa letsatsi hore e be motlakase o fapanyetsanang, o ka sebelisoang ke lisebelisoa tsa lapeng le lisebelisoa tse ling tsa elektroniki. Ena ke mosebetsi oa bohlokoa hobane boholo ba lisebelisoa tsa motlakase li sebelisa motlakase o fapanyetsanang.
2. Keketseho ea Bokhoni ba Matla: Li-inverter tsa sejoale-joale li na le theknoloji e tsoetseng pele e ka eketsang tlhahiso ea matla ea liphanele tsa letsatsi. Li-inverter tse ling li na le bokhoni ba ho ntlafatsa libaka tse phahameng tsa matla (Maximum Power Point Tracking, kapa MPPT), e leng se netefatsang hore liphanele tsa letsatsi li sebetsa ka katleho e phahameng ka ho fetisisa tlas'a maemo a fapaneng a tikoloho.
3. Laola Kopanyo ea Gridi: Inverter e tsamaisong ea phanele ea letsatsi e hoketsoeng ke gridi e hokahanya tlhahiso ea motlakase le gridi ea motlakase ea sechaba. Sena se lumella basebelisi ho romela motlakase o feteletseng o hlahisoang ke liphanele tsa letsatsi ho gridi le ho fumana mokitlane ho tsoa ho sesebelisoa ka mokhoa o tsejoang e le ho lekanya letlooa.
4. Mesebetsi ea Tšireletso le Polokeho: Li-inverter le tsona li bapala karolo ea bohlokoa ho bolokeng polokeho ea litsamaiso tsa phanele ea letsatsi. Li na le likarolo tse fapaneng tsa tšireletso, joalo ka tšireletso ea motlakase o feteletseng, tšireletso ea potoloho e khuts'oane, le ho lemoha ho itšehla thajana, tse sireletsang sistimi tšenyong le ho hloleha ho ka bang teng.
5. Tlhokomelo le Tlhahlobo: Li-inverter tse ngata tsa sejoale-joale li na le litsamaiso tsa tlhokomelo tse lumellang basebelisi ho lekola ts'ebetso ea phanele ea letsatsi ka nako ea sebele ka sesebelisoa kapa webo. Sena se etsa hore ho be bonolo ho lemoha le ho rarolla mathata kapele haeba ho hlokahala.
Mefuta ea Li-Inverter ho Litsamaiso tsa Liphanele tsa Letsatsi
Ho na le mefuta e 'maloa ea li-inverter tse sebelisoang litsamaisong tsa phanele ea letsatsi, e 'ngoe le e 'ngoe e na le melemo le mathata a eona. Mefuta e tloaelehileng haholo ea li-inverter ke ena:
1. Inverter e Ikemetseng
Li-inverter tse ikemetseng li sebelisoa lits'ebetsong tsa phanele ea letsatsi tse sa keneng ka gridi. Mofuta ona oa inverter o fetola motlakase oa DC o bolokiloeng bankeng ea betri hore e be motlakase oa AC bakeng sa tšebeliso ea lisebelisoa tsa lapeng. Li-inverter tse ikemetseng li tlameha ho tšepahala haholo hobane litlhoko tsohle tsa motlakase oa lelapa li itšetlehile ka motlakase oo li o hlahisang.
2. Inverter e tlamiloeng ka gridi
Inverter e tlamiloeng ka gridi ke mofuta oa inverter e sebelisoang lits'ebetsong tsa phanele ea letsatsi e hokahantsoeng le gridi ea motlakase ea sechaba (on-grid). Inverter ena e na le bokhoni ba ho hokahanya tlhahiso ea matla a AC le mohato le maqhubu a gridi. Molemo o moholo oa sistimi e tlamiloeng ka gridi ke hore basebelisi ba ka rekisa motlakase o feteletseng o hlahisoang ke liphanele tsa letsatsi ho k'hamphani ea litšebeletso, 'me ba sebelise motlakase o tsoang gridi ha liphanele tsa letsatsi li sa lekana.
3. Hybrid Inverter
Li-inverter tse kopantsoeng li kopanya likarolo tsa li-inverter tse ikemetseng le tse tlamiloeng ka gridi. Hangata litsamaiso tsena li kenyelletsa banka ea betri bakeng sa polokelo ea matla 'me li hokahantsoe le gridi ea motlakase ea sechaba. Li-inverter tse kopantsoeng li fa basebelisi monyetla oa ho boloka matla a hlahisoang bakeng sa tšebeliso ea morao, ho a sebelisa ka kotloloho, kapa ho a khutlisetsa ka har'a gridi. Sena se lumella tšebeliso e ntlafalitsoeng ea matla le ts'ireletso e eketsehileng ea phepelo ea motlakase.
4. Microinverter
Microinverter ke mofuta oa inverter e kentsoeng phanele e 'ngoe le e 'ngoe ea letsatsi. Sistemeng ea microinverter, phanele e 'ngoe le e 'ngoe ea letsatsi e sebetsa ka boikemelo, ho bolelang hore ts'ebetso e tlase ea phanele e 'ngoe e ke ke ea ama ts'ebetso ea tse ling. Sena se molemo haholo maemong ao karolo ea sistimi ea phanele ea letsatsi e ka 'nang ea fifala kapa ea ba le bothata ba ts'ebetso ka lebaka la maemo a tikoloho.
5. Inverter ea likhoele
Li-inverter tsa likhoele ke mofuta o tloaelehileng haholo oa li-inverter tse sebelisoang lits'ebetsong tsa phanele ea letsatsi ea lapeng. Tlhophisong ena, liphanele tse ngata tsa letsatsi li hokahantsoe ka tatellano ho etsa khoele, 'me khoele ka 'ngoe e hokahantsoe le sesebelisoa sa ho kenya likhoele. Li-inverter tsa likhoele li atisa ho ba theko e tlase ebile li bonolo ho li kenya ho feta li-microinverter, empa ts'ebetso ea sistimi eohle e ka angoa ke ts'ebetso ea phanele e sebetsang ka tlase ho tsohle khoeleng.
6. Inverter e Bohareng
Li-inverter tse bohareng li tšoana le li-inverter tsa likhoele empa li sebelisoa lits'ebetsong tse kholo tsa phanele ea letsatsi, joalo ka lits'ebetso tsa khoebo kapa lifeme tsa matla a letsatsi. Li-inverter tse bohareng li kopanya tlhahiso e tsoang likhoeleng tse ngata tsa phanele ea letsatsi ho ea sebakeng se le seng sa tlhahiso. Li nolofatsa tsamaiso le taolo ea matla empa li hloka ho kenngoa ho rarahaneng haholoanyane le litšenyehelo tse phahameng tsa pele.
Qetello
Sesebelisoa sa ho fetola motlakase ke karolo ea bohlokoa tsamaisong ea phanele ea letsatsi, se fetola motlakase oa DC o hlahisoang ke liphanele tsa letsatsi hore e be motlakase oa AC o ka sebelisoang ke lisebelisoa tsa lapeng kapa oa romeloa grid ea motlakase ea sechaba. Li-inverter li boetse li ntlafatsa ts'ebetso ea matla, li laola kopanyo ea grid, li fana ka tšireletso le ts'ireletso, 'me li fana ka tlhokomelo le tlhahlobo.
Ho na le mefuta e fapaneng ea li-inverter tse sebelisoang lits'ebetsong tsa phanele ea letsatsi, ho kenyeletsoa li-inverter tse ikemetseng, li-inverter tse tlamiloeng ka grid, li-inverter tse kopantsoeng, li-microinverter, li-string inverter le li-inverter tse bohareng. Mofuta o mong le o mong oa inverter o na le melemo le mefokolo e lokelang ho nahanoa ho latela litlhoko le maemo a itseng a sistimi ea phanele ea letsatsi e sebelisoang.
Ka ho utloisisa mesebetsi le mefuta ea li-inverter tse fumanehang, basebelisi ba ka etsa liqeto tse nang le tsebo e batsi mabapi le ho khetha inverter e loketseng sistimi ea bona ea phanele ea letsatsi, ho netefatsa katleho e ntle le ts'epo ho faneng ka matla a motlakase ho tsoa mehloling e hloekileng le e nchafatsoang.
