Makina opangira magetsi a Off-grid photovoltaic amagwiritsidwa ntchito kwambiri kumadera akutali amapiri, madera opanda magetsi, zilumba, malo olumikizirana ndi nyali zamsewu. Photovoltaic array imatembenuza mphamvu ya dzuwa kukhala mphamvu yamagetsi pansi pa kuwala, ndikupatsa mphamvu ku katunduyo kudzera musolar charge and discharge controller, ndi kulipiritsa paketi ya batri nthawi yomweyo; kulibe kuwala, batire paketi imapereka mphamvu ku katundu wa DC kudzera pamagetsi adzuwa ndi chowongolera chotulutsa. Panthawi imodzimodziyo, batire imaperekanso mphamvu mwachindunji kwa inverter yodziimira yokha, yomwe imasinthidwa kukhala njira yosinthira kudzera pa inverter yodziimira kuti ipereke mphamvu ku katundu wosinthasintha.
Mapangidwe a Solar System
(1) DzuwaBattery Module
The solar cell module ndiye gawo lalikulu ladongosolo lamagetsi adzuwa, ndipo ndi gawo lamtengo wapatali kwambiri pamagetsi a dzuwa. Ntchito yake ndikutembenuza mphamvu ya dzuwa kukhala magetsi olunjika.
(2) Wowongolera Dzuwa
Kuwongolera kwa dzuwa ndi kutulutsa kotulutsa kumatchedwanso "photovoltaic controller". Ntchito yake ndikusintha ndikuwongolera mphamvu yamagetsi yomwe imapangidwa ndi gawo la cell ya solar, kulipiritsa batire mpaka pamlingo waukulu, komanso kuteteza batri kuti isachuluke komanso kutulutsa. zotsatira. M'malo omwe ali ndi kusiyana kwakukulu kwa kutentha, wolamulira wa photovoltaic ayenera kukhala ndi ntchito ya malipiro a kutentha.
(3) Off-grid Inverter
The off-grid inverter ndiye chigawo chachikulu chamagetsi opangira magetsi kuchokera pa gridi, omwe ali ndi udindo wosintha mphamvu ya DC kukhala mphamvu ya AC kuti igwiritsidwe ntchito ndi katundu wa AC. Pofuna kupititsa patsogolo ntchito yonse ya dongosolo la mphamvu ya photovoltaic ndikuonetsetsa kuti ntchito yokhazikika ya nthawi yayitali yamagetsi, zizindikiro za ntchito za inverter ndizofunikira kwambiri.
(4) Battery Pack
Batire imagwiritsidwa ntchito makamaka posungira mphamvu kuti ipereke mphamvu zamagetsi ponyamula usiku kapena masiku amvula. Batire ndi gawo lofunika kwambiri la off-grid system, ndipo ubwino ndi kuipa kwake zimagwirizana mwachindunji ndi kudalirika kwa dongosolo lonse. Komabe, batire ndi chipangizo chokhala ndi nthawi yayifupi kwambiri pakati pa zolephera (MTBF) mu dongosolo lonse. Ngati wogwiritsa ntchito angagwiritse ntchito ndikusunga bwino, moyo wake wautumiki ukhoza kuwonjezedwa. Apo ayi, moyo wake wautumiki udzafupikitsidwa kwambiri. Mitundu ya mabatire nthawi zambiri ndi mabatire a lead-acid, mabatire opanda lead-acid-free, ndi nickel-cadmium. Makhalidwe awo akuwonetsedwa mu tebulo ili m'munsimu.

Solar off-grid System Components
Makina a photovoltaic a Off-grid nthawi zambiri amapangidwa ndi ma photovoltaic arrays opangidwa ndi ma cell a solar, solar charge and discharge controllers, mapaketi a batri, ma inverter akunja, katundu wa DC ndi katundu wa AC.
Ubwino:
1. Mphamvu ya dzuwa ndi yosatha komanso yosatha. Kutentha kwadzuwa komwe kumapezeka padziko lapansi kumatha kukwaniritsa nthawi 10,000 kuchuluka kwa mphamvu padziko lonse lapansi. Malingana ngati ma solar photovoltaic systems aikidwa pa 4% ya zipululu zapadziko lonse lapansi, magetsi opangidwa amatha kukwaniritsa zosowa za dziko lapansi. Kupanga magetsi a dzuwa ndi kotetezeka komanso kodalirika, ndipo sikudzavutika ndi vuto lamagetsi kapena kusakhazikika kwa msika wamafuta;
2. Mphamvu ya dzuwa imapezeka paliponse, ndipo imatha kupereka mphamvu pafupi, popanda kutumiza mtunda wautali, kupeŵa kutayika kwa mizere yotumizira mtunda wautali;
3. Mphamvu zadzuwa sizifuna mafuta, ndipo mtengo wake ndi wotsika kwambiri;
4. Palibe magawo osuntha opangira mphamvu ya dzuwa, sikophweka kuwonongeka, ndipo kukonza kumakhala kosavuta, makamaka koyenera kugwiritsidwa ntchito mosasamala;
5. Kupanga magetsi a dzuwa sikudzatulutsa zinyalala, kuwononga, phokoso ndi zoopsa zina zapagulu, popanda kuwononga chilengedwe, ndi mphamvu yabwino yoyera;
6. Nthawi yomanga dongosolo la mphamvu ya dzuwa ndi yaifupi, yabwino komanso yosinthika, ndipo malinga ndi kuwonjezeka kapena kuchepa kwa katundu, kuchuluka kwa mphamvu ya dzuwa kungathe kuwonjezeredwa kapena kuchepetsedwa mosasamala kuti asawonongeke.
kuipa:
1. Kugwiritsa ntchito pansi kumakhala kwapang'onopang'ono komanso mwachisawawa, ndipo kupanga magetsi kumagwirizana ndi nyengo. Sichingathe kapena kawirikawiri kupanga mphamvu usiku kapena masiku amitambo ndi mvula;
2. Kuchuluka kwa mphamvu ndi kochepa. Pansi pazikhalidwe zofananira, mphamvu yama radiation yadzuwa yomwe idalandiridwa pansi ndi 1000W/M^2. Ikagwiritsidwa ntchito mokulirapo, iyenera kukhala pamalo akulu;
3. Mtengowo udakali wokwera mtengo, ndipo ndalama zoyambira ndizokwera.
