Question

Please find the answer for the given details

Load = 1000W

UPS Input = 24V

Required Runtime = 1.5 hours

UPS Efficiency/Power Factor = 70% or 0.7

Battery type is = Lead-Acid (So runtime factor of 1.5)

what should be the battery bank capacity?

Answer 1

Hi check your answer here

Given

P=1000w

V=24v

To calculate Load for 1 hour

Load Current for 1 hour = (Runtime Factor x Load) / (UPS Efficiency x UPS Input)

= 1.5 x 1000/ (0.7*24) = 89.29A

To Calculate required Ah for 1.5 hours

Load Current for 1.5 hours

= Answer x 1.5

= 89.29 x 1.5

= 133.94Ah

Now that we know our current usage for 1.5 hours, We need battery size of 133.94Ah.

The nearest round number is 134Ah.
