How Many Amps Is 24 kW at 24V?

24 kW at 24V draws about 1,000 amps on an DC circuit at PF 0.85, typical for solar arrays, battery banks, and DC industrial equipment. Actual current varies with equipment power factor and duty cycle.

Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 24 ÷ 24 = 24,000 ÷ 24 = 1,000 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

24,000 ÷ (0.85 × 24) = 24,000 ÷ 20.4 = 1,176.47 A

Power Factor Reference (DC)

How the line current for 24 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	24 kW at 24V (DC)
Resistive (heaters, incandescent)	1	1,000 A
Fluorescent lamps	0.95	1,000 A
LED lighting	0.9	1,000 A
Synchronous motors	0.9	1,000 A
Typical mixed loads	0.85	1,000 A
Induction motors (full load)	0.8	1,000 A
Computers (without PFC)	0.65	1,000 A
Induction motors (no load)	0.35	1,000 A

AC Conversion Comparison

On DC, 24kW at 24V draws 1,000A. AC single-phase at PF 0.85 pulls 1,176.47A because reactive current is added on top of the real power.

Circuit Type	Formula	Result
DC	24,000 ÷ 24	1,000 A
AC Single Phase (PF 0.85)	24,000 ÷ (0.85 × 24)	1,176.47 A

Same kW, Other Voltages

Each destination page leads with the interpretation most common for that voltage, so the amps shown below use the same basis as the page you'd land on: single-phase for residential voltages, three-phase for commercial/industrial panel voltages, DC for low-voltage.

Frequently Asked Questions

How many amps is 24 kW at 24V?expand_more

24 kW at 24V draws about 1,000 amps on DC. Alternate cases at the same voltage: 1,176.47A on AC single-phase.

Why do industrial systems use kW instead of watts?expand_more

Industrial equipment operates at higher power levels. 24 kW is easier to express than 24,000W. The math is identical, just scaled by 1000.

What is 24 kW in watts?expand_more

24 kW equals 24,000 watts. Multiply kilowatts by 1000.

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

At 24V, this is Level 1 territory (120V AC, single-phase, typically 12-16A). A 24 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 24 kW of charging, you want Level 2 on a 240V dedicated circuit, not 120V.

How does power factor affect the amps for 24 kW at 24V?expand_more

On AC single-phase, current scales inversely with power factor. At PF 1.0 (pure resistive, like a heater), 24 kW at 24V draws 1,000A. At PF 0.80 (typical induction motor), the same real power draws 1,250A. The extra current is reactive and does no real work, but still flows through the wire and the breaker.
