(1) Hnub ci vaj huam sib luag: Lub hnub ci vaj huam sib luag yog qhov tseem ceeb ntawm lub hnub ci hluav taws xob tsim hluav taws xob thiab qhov tseem ceeb tshaj plaws ntawm lub hnub ci hluav taws xob tsim hluav taws xob. Nws txoj haujlwm yog los hloov cov hluav taws xob muaj peev xwm ntawm lub hnub mus rau hauv lub zog hluav taws xob, lossis xa mus rau lub roj teeb cia, lossis tsav lub nra mus ua haujlwm.
(2) Solar maub los: Lub luag haujlwm ntawm lub hnub ci maub los yog tswj kev ua haujlwm ntawm tag nrho lub cev, thiab tiv thaiv lub roj teeb ntawm overcharge thiab overdischarge. Nyob rau hauv qhov chaw uas muaj qhov kub thiab txias sib txawv, tus tswj tau tsim nyog yuav tsum muaj kev ua haujlwm ntawm qhov kub thiab txias. Lwm cov haujlwm ntxiv xws li cov keyboards tswj lub teeb thiab lub sijhawm tswj cov keyboards yuav tsum xaiv tau rau tus maub los;
(3) Cia roj teeb: Nws feem ntau yog gel roj teeb. Hauv cov tshuab me thiab micro, cov roj teeb nickel-hlau hydride, cov roj teeb nickel-cadmium lossis lithium roj teeb kuj tseem siv tau. Nws txoj haujlwm yog khaws cov hluav taws xob hluav taws xob tawm los ntawm lub hnub ci vaj huam sib luag thaum muaj teeb pom kev zoo, thiab tso tawm thaum xav tau.
(4) Inverter: Cov zis ncaj qha ntawm lub hnub ci zog yog feem ntau 12VDC, 24VDC, 48VDC. Txhawm rau muab lub zog rau 220VAC cov khoom siv hluav taws xob, nws yog ib qho tsim nyog los hloov DC lub zog tsim los ntawm lub hnub ci tsim hluav taws xob rau hauv AC lub zog, yog li yuav tsum muaj DC-AC inverter.
