Mapampu amadzi ndi mafiriji amafuna mphamvu zoyambira zazikulu. Onetsetsani kuti inverter ndi batri zimatha kuthana ndi kukwera kwa magetsi.
Mwachitsanzo, ngati mphamvu yonse yomwe mukufuna kugwiritsa ntchito ndi pafupifupi 800 W ndipo mukufuna kuti ikhalepo kwa maola 10, mphamvu yomwe mukufuna ndi pafupifupi 8 kWh. Poganizira momwe batire la 10 kWh limagwirira ntchito komanso momwe limasungidwira, nthawi zambiri batire la 10 kWh ndi malo abwino oyambira nyumba yapakatikati.
Kuphatikiza ndi magetsi opangira mphamvu ya dzuwa padenga: pa gridi, hybrid, ndi kunja kwa gridi
– Pa gridi yopanda batire: Malo opangira magetsi a dzuwa amalumikizidwa ku PLN, zomwe zimachepetsa mabilu masana, koma sapereka magetsi nthawi ya dama (kuti gridi ikhale yotetezeka).
– Hybrid (PLTS + batire + PLN): Yosinthasintha kwambiri. Imatha kuchajitsa mabatire kuchokera ku solar kapena PLN, ndipo imapereka chithandizo chothandizira magetsi akazima.
– Kulibe magetsi: Silikulumikizidwa ku PLN (State Electricity Company). Limafuna mabatire akuluakulu komanso kukonzekera bwino katundu, chifukwa magetsi onse amadalira mphamvu ya dzuwa ndi mabatire (ndipo nthawi zambiri jenereta yosungira).
Kwa nyumba zambiri za m'mizinda, dongosolo losakanikirana nthawi zambiri ndilo mgwirizano wabwino pakati pa chitonthozo, kulimba, ndi mtengo.
Chitetezo, malo oyikamo ndi mpweya wabwino
Mabatire ndi zida zamagetsi zambiri; kuyika kuyenera kusamala kwambiri pa chitetezo:
– Malo: Chabwino, chiyenera kukhala pamalo ouma, okhala ndi mthunzi, osatentha kwambiri, komanso otetezedwa ku kusefukira kwa madzi. Nthawi zambiri chipinda chosungiramo zinthu zofunika nthawi zambiri chimakhala chokonda.
– Mpweya wopumira: Mitundu ina ya mabatire imafuna mpweya wopumira wokhwima kwambiri. Mabatire a lithiamu nthawi zambiri sapanga mpweya ngati mabatire a wet-cell, koma amafunikirabe kuyang'anira kutentha.
- Chitetezo cha magetsi: Onetsetsani kuti pali MCB/fuse yoyenera, makina oyambira pansi, ndi chitetezo cha surge.
– BMS ndi kuwunika: BMS imaletsa kudzaza kwambiri, kutulutsa madzi mopitirira muyeso, kutentha kwambiri, komanso kutentha kwambiri. Kuwunika momwe zinthu zilili kumathandiza kuzindikira zolakwika msanga.
Gwiritsani ntchito katswiri wodziwa bwino ntchito kapena wokhazikitsa wodziwa bwino ntchito, chifukwa zolakwika pa kukhazikitsa zingayambitse kutentha kwambiri, kuwonongeka kwa zida, komanso ngakhale kuopsa kwa moto.
Kusamalira ndi moyo wonse
Mabatire amakono safuna kukonzedwa mokwanira, makamaka mabatire a lithiamu. Komabe, zizolowezi zina zabwino zimatha kutalikitsa moyo wawo:
- Pewani kutentha kwambiri; kutentha kumawonjezera kuwonongeka.
- Gwiritsani ntchito makonda a DoD ndi ndondomeko yolipirira yomwe wopanga amalangiza.
- Chitani zosintha za firmware (ngati zilipo) kuti muwongolere kukhazikika ndi chitetezo.
- Yang'anani nthawi ndi nthawi mawaya olumikizira kuti muwonetsetse kuti palibe kutayirira kapena dzimbiri.
Mabatire a lead-acid amafunika chisamaliro chowonjezera, monga kuyang'ana electrolyte (kuti aone ngati mabatire ali onyowa) komanso kupewa kuwononga theka la mphamvu pafupipafupi (zomwe zingayambitse sulfation).
Mtengo ndi phindu la ndalama
Mitengo ya mabatire apakhomo imakhudzidwa ndi mphamvu (kWh), mphamvu yotulutsa (kW), mtundu, mawonekedwe achitetezo, komanso kukhalapo kwa inverter/hybrid controller. Ndikofunikira kuwunika mtengo wa moyo wonse, osati mtengo woyambirira wokha. Mabatire okwera mtengo kwambiri okhala ndi ma cycle ambiri komanso magwiridwe antchito apamwamba nthawi zambiri amakhala otsika mtengo pakapita nthawi, makamaka ngati agwiritsidwa ntchito tsiku lililonse kuti awonjezere kugwiritsa ntchito mphamvu ya dzuwa.
Kuphatikiza apo, phindu lowonjezera la dongosololi si rupiah pa kWh yokha, komanso mtendere wamumtima panthawi yamagetsi, chitetezo cha zida zamagetsi, komanso kukhazikika kwa mphamvu.
Kutseka
Mabatire osungira mphamvu m'nyumba ndi njira yabwino kwambiri yopezera ndalama kwa iwo omwe akufuna nyumba yodzidalira, yolimba, komanso yogwira ntchito bwino. Chisankho chabwino nthawi zambiri chimadalira mabatire a lithiamu—makamaka LFP—chifukwa cha chitetezo chawo, nthawi yawo yogwira ntchito, komanso magwiridwe antchito awo. Komabe, batire yoyenera imadalira zosowa zanu: kaya mukuyang'ana kwambiri pa kusunga ndalama, kusunga ndalama, kapena kuphatikiza bwino ndi malo opangira magetsi a dzuwa padenga.
Mwa kumvetsetsa mphamvu, mphamvu, DoD, nthawi yozungulira, ndi chitetezo ndi kuyika, mutha kupanga njira yosungira mphamvu yomwe ikugwirizana ndi momwe nyumba yanu imagwiritsira ntchito. Pamapeto pake, mabatire ndi ochulukirapo kuposa "kusungira magetsi," koma ndi maziko a nyumba yanzeru yokonzekera mtsogolo mwa mphamvu.
