How Many Amps Is 23 kW at 24V?

23 kilowatts at 24V works out to roughly 958.33 amps on DC at PF 0.85. That is typical for solar arrays, battery banks, and DC industrial equipment. See the DC and alternate-phase numbers below for other circuit types.

Formulas

DC: kW to Amps

I_(A) = 1000 × P_(kW) ÷ V_(V)

1000 × 23 ÷ 24 = 23,000 ÷ 24 = 958.33 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

23,000 ÷ (0.85 × 24) = 23,000 ÷ 20.4 = 1,127.45 A

Power Factor Reference (DC)

How the line current for 23 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	23 kW at 24V (DC)
Resistive (heaters, incandescent)	1	958.33 A
Fluorescent lamps	0.95	958.33 A
LED lighting	0.9	958.33 A
Synchronous motors	0.9	958.33 A
Typical mixed loads	0.85	958.33 A
Induction motors (full load)	0.8	958.33 A
Computers (without PFC)	0.65	958.33 A
Induction motors (no load)	0.35	958.33 A

AC Conversion Comparison

On DC, 23kW at 24V draws 958.33A. AC single-phase at PF 0.85 pulls 1,127.45A because reactive current is added on top of the real power.

Circuit Type	Formula	Result
DC	23,000 ÷ 24	958.33 A
AC Single Phase (PF 0.85)	23,000 ÷ (0.85 × 24)	1,127.45 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 23 kW at 24V?expand_more

23 kW at 24V draws about 958.33 amps on DC. Alternate cases at the same voltage: 1,127.45A on AC single-phase.

What is the formula for kW to amps?expand_more

DC: Amps = (kW × 1000) ÷ Volts. AC single-phase: Amps = (kW × 1000) ÷ (Volts × PF). AC three-phase: Amps = (kW × 1000) ÷ (Volts_L-L × √3 × PF).

What size breaker would I need for 23 kW at 24V?expand_more

This is a sizing question, not a conversion question, and there is no single correct answer from a page like this. Breaker selection depends on the equipment nameplate FLA, whether the load is continuous (NEC 210.19(A) applies the 125% continuous-load rule), the conductor ampacity and temperature rating, any NEC 430/440 motor or HVAC provisions, and local code interpretation. Use the nameplate and a licensed electrician for the real install value; use this page only for the current-draw estimate that feeds into that process.

Why do industrial systems use kW instead of watts?expand_more

Industrial equipment operates at higher power levels. 23 kW is easier to express than 23,000W. The math is identical, just scaled by 1000.

How many amps does a 23 kW EV charger draw at 24V?expand_more

At 24V, this is Level 1 territory (120V AC, single-phase, typically 12-16A). A 23 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 23 kW of charging, you want Level 2 on a 240V dedicated circuit, not 120V.
