Haeba motlakase o moholo ka ho fetisisa o ntshang betri o se o boletswe bakeng sa boemo bo amehang ba tshebetso, sebedisa boleng boo e le tlhahiso ya moralo wa mantlha. Ho seng jwalo, tswela pele ka khakanyo ya motlakase o lehlakoreng la betri.
2Hakanya Nako ea Lehlakore la Betri
Ha data ya betri e tobileng e sa fumanehe, qala kaP = V × IKa hona:
Bakeng sa betri ea 16S LiFePO4 e nang le motlakase o tloaelehileng oa 51.2V o fanang ka mojaro oa 5,000W:
5,000 ÷ 51.2 ≈ 97.7A
Bakeng sa khakanyo e utloahalang haholoanyane, kenyelletsa bokgoni ba inverter:
Haeba bokgoni ba 95% bo sebediswa feela e le mohlala:5,000 ÷ (51.2 × 0.95) ≈ 102.8A. U se ke ua nahana hore 95% bakeng sa inverter e 'ngoe le e 'ngoe; sebelisa lintlha tse sebetsang tsa moetsi neng kapa neng ha li fumaneha.
3Sebelisa Voltage e Sebetsang ea Betri e Amanang
