charge controller maximum input is 24 V and 5 A. Its maximum output is 12 V and 9 A. What is the efficiency of the charge controller?
Answers
Given : a charge controller maximum input is 24 v and 5 A.Its maximum output is 12 v and 9 A.
To find : The efficiency of the charge controller.
Solution : efficiency of charge controller, η% = output power/input power × 100
= V₂I₂/V₁I₁ × 100
here, V₂ = 12Volts , I₂ = 9A , V₁ = 24 volts and I₁ = 5A
η = (12 × 9)/(24 × 5) × 100
= 9/10 × 100
= 90 %
Therefore the efficiency of the charge controller is 90% .
