Kodi mukufuna kulumikiza mapanelo awiri adzuwa ku batire imodzi?Mwafika pamalo oyenera, chifukwa tikupatsani njira kuti muchite bwino.
Momwe mungalumikizire mapanelo awiri adzuwa ku dzimbiri limodzi la batri?
Mukalumikiza mndandanda wa mapanelo adzuwa, mukulumikiza gulu limodzi kupita ku linalo.Mwa kugwirizanitsa ma solar panels, dera la chingwe limapangidwa.Waya womwe umalumikiza cholumikizira choyipa cha gulu limodzi la solar ku terminal yabwino ya gulu lotsatira, ndi zina zotero.M'ndandanda ndi imodzi mwa njira zosavuta zogwirizanitsa machitidwe anu a dzuwa.
Gawo loyamba ndikulumikiza batire yanu ku chowongolera (MPPT kapena PWM).Iyi ndi ntchito yoyamba yomwe iyenera kumalizidwa.Mutha kuwononga chowongolera ngati mulumikiza ma solar.
Zapano zomwe chowongolera chanu chimatumiza ku mabatire zimatsimikizira kuchuluka kwa mawaya.Mwachitsanzo, Renogy Rover 20A imapereka ma amps 20 ku batri.Mawaya okhala ndi mphamvu yosachepera 20Amp ndiyofunikira, monganso kugwiritsa ntchito fuse ya 20Amp pamzere.Waya wokhawo womwe uyenera kusakanikirana ndi wabwino.Ngati mukugwiritsa ntchito waya wamkuwa wosinthasintha, mufunika waya wa AWG12.Ikani fuyusi pafupi momwe mungathere ndi malumikizidwe a batri.
Kenako, lumikizani mapanelo anu adzuwa.Panthawiyi, mudzagwirizanitsa mapanelo anu awiri a dzuwa.
Izi zitha kuchitika motsatana kapena motsatana.Mukalumikiza mapanelo anu awiri motsatizana, voteji imawonjezeka, pomwe kuwalumikiza mofananira kumawonjezera zomwe zikuchitika.Mawaya ang'onoang'ono amafunikira mukamayimba motsatizana kusiyana ndi pamene mawaya amafanana.
Mawaya a solar panel adzakhala aafupi kwambiri kuti angafikire chowongolera chanu.Mutha kuyilumikiza ku chowongolera chanu pogwiritsa ntchito chingwechi.Kulumikizana kwa mndandanda kumagwiritsidwa ntchito nthawi zambiri.Zotsatira zake, tipita patsogolo ndikupanga kulumikizana kwa mndandanda.Ikani chojambulira pafupi ndi mabatire momwe mungathere.Ikani chowongolera chanu pafupi ndi ma sola awiri momwe mungathere kuti muchepetse kutayika kwa waya.Kuti muchepetse kutayika, chotsani zolumikizira zilizonse zotsala zolumikiza ma sola ku chowongolera.
Kenako, lumikizani zonyamula zazing'ono za DC ku chowongolera chowongolera.Ngati mukufuna kugwiritsa ntchito inverter, gwirizanitsani ndi zolumikizira batire.Taganizirani chithunzi chili m'munsichi monga chitsanzo.
Pakalipano yomwe imayenda kudutsa mawaya imatsimikizira kukula kwake.Ngati inverter yanu imakoka ma amps 100, chingwe chanu ndi zophatikizika ziyenera kukula bwino.
Momwe mungagwiritsire ntchito mapanelo awiri adzuwa pa batire imodzi?
Kuti muchite izi, muyenera kulumikiza mapanelo mofanana kuti mugwiritse ntchito makina a batri awiri.Gwirizanitsani zotsutsana ndi zowonongeka ndi zowonongeka kuti mugwirizane ndi magetsi awiri a dzuwa mofanana.Mapanelo onsewa amayenera kukhala ndi mphamvu yofanana kuti atulutse kwambiri.Mwachitsanzo, solar panel ya 115W SunPower ili ndi izi:
Mphamvu yapamwamba kwambiri ndi 19.8 V.
Udindo wapamwamba kwambiri womwe ulipo = 5.8 A.
Mphamvu zoyezera kwambiri = Ma Volts x Alipo = 19.8 x 5.8 = 114.8 W
Pamene awiri mwa mabulangetewa alumikizidwa mofanana, mphamvu yaikulu kwambiri ndi 2 x 19.8 x 5.8 = 229.6 W.
Ngati mapanelo awiri ali ndi ziwongola dzanja zosiyana, gulu lomwe lili ndi voteji yotsika kwambiri limatsimikizira voteji yabwino kwambiri pamakina.Wodabwa?Tiyeni tiwone chomwe chimachitika pamene gulu lathu la solar ndi solar blank blanket zilumikizidwa.
18.0 V ndiye magetsi abwino kwambiri.
Kuchuluka komweku komweko ndi 11.1 A.
19.8 volts ndiye mphamvu yayikulu kwambiri.
Chiwerengero chachikulu chapano ndi 5.8 A.
Kugwirizanitsa iwo mu zokolola zofanana:
(304.2 W) = mphamvu zoyezera kwambiri (18.0 x 11.1) Kuphatikiza (18.0 x 5.8)
Zotsatira zake, kupanga mabulangete a dzuwa kudzatsitsidwa ndi 10% mpaka (18.0 x 5.8 =-RRB-104.4 W).
Njira yabwino yolumikizira ma solar 2 ndi iti?
Pali njira ziwiri zosiyana zowagwirizanitsa, ndipo tidzakambirana zonse ziwiri apa.
Monga mabatire, ma solar panels ali ndi ma terminals awiri: imodzi yabwino ndi ina yolakwika.
Pamene terminal yabwino ya gulu limodzi ilumikizidwa ku terminal yoyipa ya ina, kulumikizana kwa mndandanda kumapangidwa.Dongosolo la gwero la PV limakhazikitsidwa pomwe ma solar awiri kapena kupitilira apo alumikizidwa motere.
Pamene mapanelo a dzuwa alumikizidwa motsatizana, voteji imawonjezeka pomwe amperage imakhala yosasinthika.Pamene mapanelo awiri a dzuwa okhala ndi ma 40 volts ndi 5 amps alumikizidwa mndandanda, voteji yotsatizana ndi 80 volts ndipo amperage imakhalabe pa 5 amps.
Mphamvu yamagetsi yamagulu imawonjezedwa ndikulumikiza mapanelo motsatizana.Izi ndizofunikira chifukwa inverter mu solar power system iyenera kugwira ntchito pamagetsi odziwika kuti igwire bwino ntchito.
Chifukwa chake mumalumikiza ma solar anu pamndandanda kuti mukwaniritse zofunikira zawindo lamagetsi la inverter yanu.
Pamene mapanelo adzuwa ali ndi mawaya mofanana, cholumikizira chabwino cha gulu limodzi chimalumikizana ndi malo abwino a china, ndipo ma terminals olakwika a mapanelo onsewo amalumikizana.
Mizere yabwino imalumikizana ndi kulumikizana kwabwino mkati mwa bokosi lophatikizira, pomwe mawaya oyipa amalumikizana ndi cholumikizira cholakwika.Pamene mapanelo angapo alumikizidwa mofanana, gawo lotulutsa la PV limapangidwa.
Pamene mapanelo a dzuwa alumikizidwa motsatizana, amperage imakwera pomwe voteji imakhala yokhazikika.Zotsatira zake, kuyatsa mapanelo ofanana mofananamo monga kale kumapangitsa kuti voteji ikhale pa 40 volts koma imawonjezera mphamvu mpaka 10 amps.
Mutha kuwonjezera ma solar owonjezera omwe amapanga mphamvu popanda kupitilira zoletsa zamagetsi zogwiritsira ntchito inverter polumikiza mofananira.Ma inverters alinso ochepa ndi amperage, omwe amatha kugonjetsedwa ndikulumikiza ma solar panels anu mofanana.
