How Many Amps Is 16.15 kW at 24V?

16.15 kilowatts at 24V works out to roughly 672.88 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 × 16.15 ÷ 24 = 16,149 ÷ 24 = 672.88 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

16,149 ÷ (0.85 × 24) = 16,149 ÷ 20.4 = 791.62 A

Power Factor Reference (DC)

How the line current for 16.15 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	16.15 kW at 24V (DC)
Resistive (heaters, incandescent)	1	672.88 A
Fluorescent lamps	0.95	672.88 A
LED lighting	0.9	672.88 A
Synchronous motors	0.9	672.88 A
Typical mixed loads	0.85	672.88 A
Induction motors (full load)	0.8	672.88 A
Computers (without PFC)	0.65	672.88 A
Induction motors (no load)	0.35	672.88 A

AC Conversion Comparison

On DC, 16.15kW at 24V draws 672.88A. AC single-phase at PF 0.85 pulls 791.62A because reactive current is added on top of the real power.

Circuit Type	Formula	Result
DC	16,149 ÷ 24	672.88 A
AC Single Phase (PF 0.85)	16,149 ÷ (0.85 × 24)	791.62 A

Frequently Asked Questions

How many amps is 16.15 kW at 24V?expand_more

16.15 kW at 24V draws about 672.88 amps on DC. Alternate cases at the same voltage: 791.62A on AC single-phase.

What is 16.15 kW in watts?expand_more

16.15 kW equals 16,149 watts. Multiply kilowatts by 1000.

How much does 16.15 kW cost to run?expand_more

16.15 kW costs $2.75 per hour at $0.17/kWh (US residential average, last reviewed April 2026). At 8 hours/day that is $658.88 per month.

How does power factor affect the amps for 16.15 kW at 24V?expand_more

On AC single-phase, current scales inversely with power factor. At PF 1.0 (pure resistive, like a heater), 16.15 kW at 24V draws 672.88A. At PF 0.80 (typical induction motor), the same real power draws 841.09A. The extra current is reactive and does no real work, but still flows through the wire and the breaker.

How many amps does a 16.15 kW EV charger draw at 24V?expand_more

At 24V, this is Level 1 territory (120V AC, single-phase, typically 12-16A). A 16.15 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 16.15 kW of charging, you want Level 2 on a 240V dedicated circuit, not 120V.
