Converting Solar Energy into Electrical Energy

Click For Summary
SUMMARY

The discussion focuses on calculating the current drawn by a solar-powered motor with specifications of 36V maximum voltage, 300A maximum current, 93% efficiency, 2.5mΩ resistance, and 12kW maximum power. The user seeks to determine the current input from the battery based on these parameters. The conversation highlights the significant current draw, which can exceed 50 times that of a typical car starter using a 12-volt battery.

PREREQUISITES
  • Understanding of electrical engineering principles, particularly Ohm's Law
  • Familiarity with solar energy systems and their components

I am currently working on a project that requires me to design and analyse a solar powered. My motor has features such; 36v (Max), 300A (Max), 93% efficiency, 2.5mΩ, 12kW (Max).

I used the maximum power and the efficiency to calculate the power input (from the battery). How do i calculate the amount of current that will be drawn by motor from the battery?

I am a Mechanical Engineering student
Thanx

Sounds like a homework problem. Did you take Physics 101 yet? The current is easily over 50x the current drawn by the starter in my car with a 12-volt battery.
