Ukukhetha i-BMS yenkqubo yokugcina amandla ye-LiFePO4 akulula njengokufanisa amandla e-inverter ne-100A, 150A, okanye i-200A BMS.
Umbane we-BMS ochanekileyo uxhomekeke kumbane osecaleni kwebhetri ofunwa yi-inverter—hayi amandla e-inverter kuphela. Inkqubo yokukhetha esebenzayo yile:
Impendulo ekhawulezileyo: Musa ukukhetha i-BMS Current kwi-Inverter Watts yodwa
Qala ngedatha ye-inverter echanekileyo. Jonga ezi parameter zintlanu:
- Amandla asebenzayo aqhubekayo (W)
- Uluhlu lwevolthi yokusebenza yebhetri/DC (V)
- Umbane wokukhupha ibhetri ophezulu (A)
- Umbane webhetri ophezulu (A)
- Amandla okunyuka/ukuphakama kunye nobude bexesha
Amandla omthwalo webhetri ≈ Amandla omthwalo we-AC ÷ (I-voltage yebhetri × Ukusebenza kakuhle kwe-Inverter)
Umzekelo, i-5,000W ÷ 51.2V ≈ 97.7A. Kodwa i-97.7A yindlela yokubala yangoku eqikelelweyo—ayibobungqina bokuba i-100A BMS ifanelekile.
Amanyathelo ama-5 okufumanisa i-BMS Current

2Qikelela iBetri-Icala langoku
Xa idatha yangoku yebhetri ingafumaneki, qala ngoP = V × IKe ngoko:
Kwibhetri ye-16S LiFePO4 enevolthi encinci ye-51.2V enika umthwalo we-5,000W:
5,000 ÷ 51.2 ≈ 97.7A
Ukuze ufumane uqikelelo olusengqiqweni ngakumbi, faka ukusebenza kakuhle kwe-inverter:
Ukuba ukusebenza kakuhle kwe-95% kusetyenziswa kuphela njengomzekelo:5,000 ÷ (51.2 × 0.95) ≈ 102.8AMusa ukucinga ukuba i-95% kwi-inverter nganye; sebenzisa idatha efanelekileyo yomenzi nanini na xa ikhona.
3Sebenzisa iVoltage yokusebenza yeBhetri efanelekileyo
Ngamandla afanayo,i-voltage yebhetri ephantsi ithetha ukuba ibhetri inamandla aphezulu.
