Mefuta ea li-Solar Regulators
Ho na le mefuta e 'meli ea mantlha ea li-conditioner tsa letsatsi tse fumanehang bakeng sa liphanele tsa letsatsi tse nkehang habonolo.Pulse Width Modulation (PWM) le Maximum Power Point Tracking (MPPT).Kaofela ba na le melemo le bofokoli ba bona, ho bolelang hore e 'ngoe le e' ngoe e loketse maemo a fapaneng a likampo.
Pulse Width Modulation (PWM)
Pulse Width Modulation (PWM), molaoli o na le khokahano e tobileng pakeng tsa karolo ea letsatsi le betri, 'me o sebelisa mochine oa "fast switching" ho laola tefiso e phallang ka har'a betri.Phetoho e lula e bulehile ka ho feletseng ho fihlela betri e fihla mocheso oa sink, ka nako eo sesebelisoa se qala ho bula le ho koala makhetlo a makholo ka motsotsoana ho fokotsa hona joale ha o ntse o boloka motlakase o sa fetohe.
Ka khopolo, mofuta ona oa khokahanyo o fokotsa katleho ea phanele ea letsatsi hobane matla a phanele a theoleloa ho bapisa matla a betri.Leha ho le joalo, tabeng ea liphanele tsa letsatsi tse nkehang kampong, phello e sebetsang e fokola haholo, kaha maemong a mangata matla a phahameng a phanele a ka bang 18V feela ('me a fokotseha ha phanele e ntse e futhumala), athe motlakase oa betri hangata o pakeng tsa 12-13V. (AGM) kapa 13-14.5V (Lithium).
Leha ho na le tahlehelo e nyane ea ts'ebetso, balaoli ba PWM ka kakaretso ba nkuoa e le khetho e ntle ea ho kopanya le liphanele tsa letsatsi tse nkehang.Melemo ea balaoli ba PWM ha e bapisoa le balekane ba bona ba MPPT ke boima bo tlaase le ho tšepahala ho hoholo, e leng lintlha tsa bohlokoa ha ba hloma liahelo ka nako e telele kapa libakeng tse hōle moo tšebeletso e ka 'nang ea se ke ea fumaneha habonolo' me ho ka ba thata ho fumana Alternative regulator.
Maximum Power Point Tracking (MPPT)
Boholo ba ho latela lintlha tsa matla a MPPT, molaoli o na le bokhoni ba ho fetola motlakase o feteletseng hore e be hona joale tlas'a maemo a nepahetseng.
Molaoli oa MPPT o tla lula a lekola matla a phanele, a lulang a fetoha ho latela lintlha tse kang mocheso oa phanele, maemo a leholimo le boemo ba letsatsi.E sebelisa motlakase o felletseng oa phanele ho bala (track) motsoako o motle ka ho fetisisa oa voltage le oa hajoale, ebe e fokotsa voltage ho tsamaisana le matla a ho tjhaja a betri hore e khone ho fana ka hona joale ho betri (hopola matla = voltage x current) .
Empa ho na le tlhokomeliso ea bohlokoa e fokotsang phello e sebetsang ea balaoli ba MPPT bakeng sa lisebelisoa tsa letsatsi tse nkehang.Ho fumana molemo ofe kapa ofe oa 'nete ho molaoli oa MPPT, motlakase oa phanele o lokela ho ba bonyane 4-5 volts ho feta tefiso ea betri.Kaha boholo ba liphanele tsa letsatsi tse nkehang li na le matla a maholo a ho pota 18-20V, a ka theohelang ho 15-17V ha a chesa, athe boholo ba libeteri tsa AGM li pakeng tsa 12-13V le libeteri tse ngata tsa lithium pakeng tsa 13-14.5V Nakong ena, phapang ea motlakase ha e lekane hore mosebetsi oa MPPT o be le phello ea sebele ho motlakase oa ho tjhaja.
Ha ho bapisoa le balaoli ba PWM, balaoli ba MPPT ba na le bothata ba ho ba boima ba boima ba 'mele' me ka kakaretso ba sa tšepahale.Ka lebaka lena, le tšusumetso ea bona e nyane ho kenyelletso ea matla, u ke ke ua li bona hangata li sebelisoa ka mekotleng e phuthoang ea letsatsi.
