Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 16.57 ÷ 24 = 16,570 ÷ 24 = 690.42 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

16,570 ÷ (0.85 × 24) = 16,570 ÷ 20.4 = 812.25 A

Power Factor Reference (DC)

How the line current for 16.57 kW at 24V changes with load power factor, on the same DC circuit basis the rest of the page uses. DC has no power factor; PF 1.0 represents resistive AC loads.

Load Type	PF	16.57 kW at 24V (DC)
Resistive (heaters, incandescent)	1	690.42 A
Fluorescent lamps	0.95	690.42 A
LED lighting	0.9	690.42 A
Synchronous motors	0.9	690.42 A
Typical mixed loads	0.85	690.42 A
Induction motors (full load)	0.8	690.42 A
Computers (without PFC)	0.65	690.42 A
Induction motors (no load)	0.35	690.42 A

AC Conversion Comparison

On DC, 16.57kW at 24V draws 690.42A. AC single-phase at PF 0.85 pulls 812.25A because reactive current is added on top of the real power.

Circuit Type	Formula	Result
DC	16,570 ÷ 24	690.42 A
AC Single Phase (PF 0.85)	16,570 ÷ (0.85 × 24)	812.25 A

Frequently Asked Questions

How many amps is 16.57 kW at 24V?expand_more

16.57 kW at 24V draws about 690.42 amps on DC. Alternate cases at the same voltage: 812.25A on AC single-phase.

How many amps does a 16.57 kW EV charger draw at 24V?expand_more

At 24V, this is Level 1 territory (120V AC, single-phase, typically 12-16A). A 16.57 kW draw on a standard 120V household outlet is at or above the 1,440W NEC 210.19(A) continuous figure, which is why Level 1 EVSE ships at 1.4-1.9 kW and takes 20+ hours for a full charge. If you need 16.57 kW of charging, you want Level 2 on a 240V dedicated circuit, not 120V.

Why do industrial systems use kW instead of watts?expand_more

Industrial equipment operates at higher power levels. 16.57 kW is easier to express than 16,570W. The math is identical, just scaled by 1000.

Is 16.57 kW single-phase or three-phase?expand_more

16.57 kW is typically three-phase in commercial and industrial settings.

How much does 16.57 kW cost to run?expand_more

16.57 kW costs $2.82 per hour at $0.17/kWh (US residential average, last reviewed April 2026). At 8 hours/day that is $676.06 per month.
