Kodi mapanelo oyendera dzuwa amapanga bwanji magetsi?

Ma sola onyamulika amagwira ntchito pojambula kuwala kwa dzuwa ndikusintha kukhala magetsi othandiza kudzera pa chipangizo chotchedwa charge controller kapena chowongolera.Chowongoleracho chimalumikizidwa ndi batri, ndikuyisunga.

Kodi solar conditioner ndi chiyani?

Solar conditioner imatsimikizira kuti magetsi opangidwa ndi solar panel amasamutsidwa mwanzeru ku batri m'njira yoyenera chemistry ya batri ndi mulingo wacharge.Wowongolera wabwino adzakhala ndi ma aligorivimu opangira masitepe angapo (nthawi zambiri masitepe 5 kapena 6) ndikupereka mapulogalamu osiyanasiyana amitundu yosiyanasiyana ya mabatire.Owongolera amakono, apamwamba kwambiri adzaphatikiza mapulogalamu apadera a mabatire a Lithium, pomwe mitundu yambiri yakale kapena yotsika mtengo idzakhala ya mabatire a AGM, Gel ndi Wet.Ndikofunika kuti mugwiritse ntchito pulogalamu yoyenera yamtundu wa batri yanu.

Chowongolera bwino cha solar chidzaphatikiza mabwalo angapo achitetezo amagetsi kuti ateteze batri, kuphatikiza chitetezo cha reverse polarity, chitetezo chozungulira chachifupi, chitetezo chobwerera kumbuyo, chitetezo chacharge, chitetezo cha overvoltage kwakanthawi, komanso kuteteza kutentha kwambiri.

Mitundu ya Solar Regulators

Pali mitundu iwiri ikuluikulu ya ma solar conditioner omwe amapezeka pamapanelo onyamulika.Pulse Width Modulation (PWM) ndi Maximum Power Point Tracking (MPPT).Onse ali ndi ubwino wawo ndi zovuta zawo, zomwe zikutanthauza kuti aliyense ndi woyenera kumisasa yosiyana.

Pulse Width Modulation (PWM)

Pulse Width Modulation (PWM), chowongolera chimakhala ndi kulumikizana kwachindunji pakati pa solar panel ndi batire, ndipo amagwiritsa ntchito njira ya "kusintha mwachangu" kuwongolera kuchuluka kwa batire.Kusinthaku kumakhalabe kotseguka mpaka batire ifika pamagetsi akumira, pomwe chosinthiracho chimayamba kutseguka ndikutseka kangapo pamphindikati kuti muchepetse mphamvuyi ndikusunga voteji nthawi zonse.

Mwachidziwitso, kulumikizana kwamtunduwu kumachepetsa mphamvu ya solar panel chifukwa voteji ya gululi imatsitsidwa kuti igwirizane ndi mphamvu ya batri.Komabe, pankhani ya mapanelo oyendera dzuwa, zotsatira zake zimakhala zochepa, chifukwa nthawi zambiri mphamvu yamagetsi yamagetsi imakhala pafupifupi 18V (ndipo imatsika pomwe gulu likuwotcha), pomwe mphamvu ya batire nthawi zambiri imakhala pakati pa 12-13V. (AGM) kapena 13-14.5V (Lithium).

Ngakhale kutayika pang'ono pakuchita bwino, owongolera a PWM nthawi zambiri amawonedwa ngati chisankho chabwinoko pakuyanjanitsa ndi ma solar osunthika.Ubwino wa olamulira a PWM poyerekeza ndi anzawo a MPPT ndi otsika kulemera komanso kudalirika kwakukulu, zomwe ndizofunikira kwambiri pomanga msasa kwa nthawi yaitali kapena kumadera akutali komwe ntchito sizingakhale zosavuta ndipo zingakhale zovuta kupeza Alternative regulator.

Kutsata kwa Power Point (MPPT)

Kutsata kwamphamvu kwambiri kwa MPPT, wowongolera amatha kusintha ma voliyumu owonjezera kukhala owonjezera pamikhalidwe yoyenera.

Woyang'anira MPPT aziwunika pafupipafupi mphamvu ya gulu, yomwe ikusintha mosalekeza kutengera kutentha kwa gulu, nyengo komanso komwe kuli dzuwa.Imagwiritsa ntchito voteji yonse ya gululo kuwerengera (kutsata) kuphatikiza kwabwino kwambiri kwamagetsi ndi apano, kenako imachepetsa mphamvu yamagetsi kuti ifanane ndi voteji ya batire kuti ipereke zowonjezera pakalipano (kumbukirani mphamvu = voliyumu x yapano) .

Koma pali chenjezo lofunika lomwe limachepetsa mphamvu ya olamulira a MPPT pamapanelo oyendera dzuwa.Kuti mupeze phindu lenileni kuchokera kwa wolamulira wa MPPT, magetsi pagawo ayenera kukhala osachepera 4-5 volts kuposa mphamvu ya batri.Popeza kuti mapanelo ambiri onyamula dzuwa amakhala ndi max voltage pafupifupi 18-20V, omwe amatha kutsika mpaka 15-17V akatentha, pomwe mabatire ambiri a AGM ali pakati pa 12-13V ndi mabatire ambiri a lithiamu pakati pa 13-14.5V Panthawiyi, kusiyana kwa voliyumu sikokwanira kuti ntchito ya MPPT ikhale ndi zotsatira zenizeni pakalipano.

Poyerekeza ndi olamulira a PWM, olamulira a MPPT ali ndi vuto lolemera kwambiri komanso osadalirika.Pazifukwa izi, komanso kukhudza kwawo pang'ono pakuyika mphamvu, simudzawawona akugwiritsidwa ntchito m'matumba a solar.
