Ha batho ba qala ho ithuta ka liphanele tsa letsatsi, ba ka nahana hore ts'ebetso e bonolo joalo ka "liphanele li monya khanya ea letsatsi, 'me mabone a ntse a tuka." Empa ho na le sesebelisoa se le seng sa bohlokoa se etsang mosebetsi oa morao-rao - inverter. Joale, inverter e etsa eng tsamaisong ea liphanele tsa letsatsi? Karabelo e tsoela pele ho feta phetoho ea matla a mantlha.
Ho sa tsotelehe hore na o tjhaja ntlo Denver, Colorado, kapa o matlafatsa setshelo se sebelisang matla a letsatsi Lusaka, Zambia, inverter e e bulela kaofela, e bolokehile ebile e utloahala, ka mokhoa o atlehileng, 'me e lekana le lisebelisoa tsa hau kapa grid.
DC ho AC - Karolo ea Bohlokoa ka ho Fetisisa ea Inverter
Liphanele tsa letsatsi li hlahisa motlakase o tobileng (DC), empa matlo, likhoebo le marang-rang li sebetsa ka mokhoa o fapaneng oa hona joale (AC). Marokho a inverter a arohanang ka ho fetolela DC ho AC e le hore o khone ho matlafatsa lihatsetsi, mabone, li-fan-kapa lisebelisoa tsa indasteri-ntle le ho foka potoloho.
Haeba u ne u se na inverter, mahlaseli a letsatsi a hau a ne a tla ba haufi le ho hloka thuso ntle le haeba o ne o e-na le lisebelisoa tsohle tse lumellanang le DC. Kahoo, inverter ke sehokelo lipakeng tsa matla a letsatsi a hloekileng le ts'ebeliso e tloaelehileng.
Ka 2022 Himachal Pradesh, India, ts'ebetso ea sechaba, lienjineri tsa kantle tsa bongaka tsa mahaeng li kentse sistimi ea letsatsi e nyalisitsoeng. Mosebetsi oa bobeli oa inverter ho etsa phetoho ea DC-AC le tsamaiso ea betri e ne e le ea bohlokoa ho netefatsa phepelo e tsitsitseng ea motlakase bakeng sa ho buuoa ke bakuli.
Kopanya le Grid (kapa Che)
Ho na le lihlopha tse peli tse pharaletseng tsa li-inverters lits'ebetsong tsa letsatsi:
- Li-inverters tse kopantsoeng ke gridi:Li lumellana le matla a utility. Li tima ka bo tsona nakong ea ho tima ha motlakase (anti-islanding) 'me li na le ho tšehetsa metering ea marang-rang.
- Li-inverters tse kantle ho grid:Tsena li sebetsa ka botsona, li boloka matla a setseng ka har'a libeteri hore li sebelisoe hamorao.
Haeba grid e hloleha, na inverter ea hau e ka tsoela pele ho fana ka motlakase ntlong ea hau? Seo se ipapisitse le - ntle le haeba o na le inverter e nyalisitsoeng le betri ea bekapo, litsamaiso tse ngata tse tlamelletsoeng ke grid lia tima molemong oa polokeho.
Ho SoCal, sebaka sa mollo, beng ba matlo ba ntse ba batla li-inverters tse nyalisitsoeng tse nang le switchover ea othomathike ho li-betri nakong ea ho khaoha ha motlakase, ho fokotsa ho ts'epa li-grid tsa sketchy.
Laola Phallo ea Matla, Polokeho, le Tlhokomelo
Li-inverters tsa letsatsi kajeno li etsa ho fetang feela ho fetola motlakase. Mesebetsi ea mantlha ke:
- MPPT (Tsamaiso e Phahameng ea Matla a Matla):Ho eketsa matla ho tsoa liphanele tsa hau leha maemo a letsatsi a fetoha.
- Khokahano le taolo ea betri:Bakeng sa lisebelisoa tsa hybrid le off-grid.
- Polokeho likarolo:Tšireletso e feteletseng, tšireletso ea potoloho e khutšoanyane, khahlanong le sehlekehlekeng.
- Ho beha leihlo ka nako ea sebele:ka lisebelisoa kapa li-portal tsa marang-rang ho bona ts'ebetso, tlhahiso le liphoso.
Na li-inverters tsohle tsa letsatsi li bohlale? Che. Tse ling tsa mantlha li fetisa matla feela, ha tse ling li na le ts'ebetso ea smart-grid, tlhokomeliso ea li-smartphone, le kabo ea mojaro o feto-fetohang.
Mohlala oa mohlala: Mohala oa Solar Container naheng ea Ghana
Ka 2023, mokhatlo o seng oa 'muso o Tamale, Ghana, o ile oa kenya k'hontheinara ea letsatsi bakeng sa ho matlafatsa sekolo sa mosebetsi oa matsoho. Kenyelletso e kenyellelitse 12 kW solar array, libeteri tsa lithium, le an LZYESS hybrid solar inverter. Inverter e nolofalitse lisebelisoa tsa letsatsi, ho tjhaja betri, le grid bypass-hole ho tloha dashboard. Sena se ile sa lumella batsamaisi ba likolo hore ba lule ba le sieo tsamaisong ea tsamaiso le ho lula maemong a bona a matichere.
Ho Khetha Inverter e Nepahetseng bakeng sa Kemiso ea Hao
Ha se sistimi e ngoe le e ngoe e hlokang mofuta o tšoanang oa inverter. Melao e meng e akaretsang ke ena:
| Mofuta oa Sisteme | Ho Hlokahala Inverter | Lintlha Tseo U Lokelang ho li Batla |
| E tlamiloe ke marang-rang | Khoele / Microinverter | Ho latela marang-rang (UL/IEC), MPPT |
| Off-grid | Inverter e ikemetseng | Ho tjhaja betri, wave sine wave |
| Hybrid | Hybrid inverter | AC-DC switching, tšehetso ea betri, likarolo tse bohlale |
Se ke oa lebala ho batla litifikeiti tse kang UL 1741, IEC 62109, kapa letšoao la CE, ho latela sebaka sa hau. Li-inverters tse hlokang setifikeiti se nepahetseng li tla liehisa lits'ebetso esita le ho etsa hore litumello tsa lehae li se ke tsa sebetsa.
Inverter ke Pelo ea Solar System ea Hau. Liphanele tsa letsatsi li ka khantša khanya eohle, empa inverter ke kelello le pelo tse e etsang hore e sebetse. E fana ka matla, e laola phallo, e boloka masala, e bua le marang-rang, esita le ho u tsebisa haeba ho na le phoso. Ntle le eona, matla a letsatsi a ka be a sa sebetse ho sebelisoa lits'ebetsong tsa lefats'e la nnete.
'Me ha u nahana ka likarolo tse kang polokelo ea betri kapa taolo e bohlale ea mojaro, ho tsetela hanyane ho feta bakeng sa inverter e ntle qalong ho etsa hore sistimi ea hau e fetohe habonolo le ho paka bokamoso.
