Uri kuronga kugadzira sisitimu yekuchengetera magetsi pamba asi unonzwa kuremerwa neruzivo rwehunyanzvi here? Kubva kuma inverter nema battery cells kusvika kuma wiring nema protection board, chimwe nechimwe chikamu chinoita basa rakakosha mukuona kuti zvinoshanda uye zvakachengeteka. Ngationgororei zvinhu zvakakosha zvekufunga nezvazvo pakusarudza sisitimu yako.
Danho 1: Tanga neInverter
Iyo inverter ndiyo moyo wesystem yako yekuchengetera simba, inoshandura simba reDC kubva kumabhatiri kuenda kusimba reAC rekushandisa pamba.chiyero chesimbazvinokanganisa zvakananga mashandiro uye mutengo. Kuti uone saizi chaiyo, verenga yakokudiwa kwesimba kwakanyanya.
Muenzaniso:
Kana kushandiswa kwako kwakanyanya kuchisanganisira poto yekubikira ye2000W induction uye kettle yemagetsi ye800W, simba rese rinodiwa i2800W. Zvichienderana nekuwanda kwezvinodiwa zvechigadzirwa, sarudza inverter ine zvirinaniKukwanisa kwe3kW(kana kuti yakakwira kuti pave nemuganhu wekuchengetedza).
Zvinhu Zvinonyanya Kukosha paKupinza Voltage:
MaInverter anoshanda pamagetsi chaiwo (semuenzaniso, 12V, 24V, 48V), ayo anotonga voltage yebhatiri rako. Mavoltage akakwira (senge 48V) anoderedza kurasikirwa kwesimba panguva yekushandura, zvichivandudza kushanda zvakanaka. Sarudza zvichienderana nehukuru hwesystem yako uye bhajeti.
Danho rechipiri: Verenga Zvinodiwa paBhangi reBhatiri
Kana inverter yasarudzwa, gadzira bhatiri rako. Kune sisitimu ye48V, mabhatiri e-lithium iron phosphate (LiFePO4) anonyanya kufarirwa nekuda kwekuchengetedzeka kwawo uye kugara kwenguva refu. Bhatiri re48V LiFePO4 rinowanzo kuve neMasero gumi nematanhatu akatevedzana(3.2V pasero rega rega).
Fomura Yakakosha Yekuyera Kwazvino:
Kuti udzivise kupisa zvakanyanya, verenga huwandu hwekushanda kwakawanda kwazvinouchishandisa nzira mbiri:
1.Kuverenga Kwakavakirwa paInverter:
Current=Simba reInverter (W)Voltage yekupinda (V)×1.2 (chinhu chekuchengetedza) Current=Voltage yekupinda (V)Simba reInverter (W)×1.2 (chinhu chekuchengetedza)
Kune inverter ye5000W pa48V:
500048×1.2≈125A485000×1.2≈125A
2.Kuverengera Kwakavakirwa paSero (Zvimwe Zvinochengetedza):
Current=Simba reInverter (W)(Kuwanda kweSero × Voltage Yekubuda Kwesimba Rishoma)×1.2Current=(Kuwanda kweSero × Voltage Yekubuda Kwesimba Rishoma)Simba reInverter (W)×1.2
Kune masero gumi nematanhatu ari pa 2.5V discharge:
5000(16×2.5)×1.2≈150A(16×2.5)5000×1.2≈150A
Zvinokurudzirwa:Shandisa nzira yechipiri kuti uwane mikana yakachengeteka yepamusoro.
Danho rechitatu: Sarudza Zvikamu zveWiring neDziviriro
Tambo nemabhazi:
- Tambo dzeKuburitsa:Pamagetsi e150A, shandisa waya yemhangura ye18 sq.mm (yakayerwa pa8A/mm²).
- Zvinobatanidza Pakati Pemasero:Sarudza mabhazi emhando ye25 sq.mm emhangura-aruminiyamu (ane chiyero che6A/mm²).
Bhodhi reDziviriro (BMS):
SarudzaSisitimu yekutarisira mabhatiri ine chiyero che150A (BMS)Ita shuwa kuti inotsanangurakugona kuripo kunoramba kuripo, kwete peak current. Kune mabhatiri akawanda, sarudza BMS inemabasa akaenzana ekuderedza magetsikana kuwedzera module yekunze yakafanana kuti ienzanise mitoro.
Nhanho 4: Masisitimu eBhatiri Akafanana
Kuchengetedza simba remagetsi kumba kunowanzoda mabhatiri akawanda panguva imwe chete.mamodules akasimbiswa akafananakana BMS ine balancing yakavakirwa mukati kudzivirira kusachaja/kuburitsa mabhatiri zvisina kuenzana. Dzivisa kubatanidza mabhatiri asina kuenzana kuti uwedzere hupenyu hwebasa.
Mazano Ekupedzisira
- Isa zvinhu zvinokosha pakutangaMasero eLiFePO4kuchengetedzeka uye hupenyu hwekufamba nebhasikoro.
- Simbisa zvitupa (semuenzaniso, UL, CE) zvezvikamu zvese.
- Bvunza nyanzvi kana paine zvinhu zvakaoma kuisa.
Nekugadzirisa inverter yako, bhatiri, uye zvikamu zvekudzivirira, uchavaka sisitimu yekuchengetedza simba repamba yakavimbika uye inoshanda. Kuti unyatsoongorora zvakadzama, tarisa gwara redu revhidhiyo rine ruzivo rwekugadzirisa magadzirirwo emabhatiri e lithium!
