How Many Amps Is 2.76 kW at 24V?

2.76 kW at 24V draws about 115 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 × 2.76 ÷ 24 = 2,760 ÷ 24 = 115 A

AC Single Phase (PF = 0.85)

I_(A) = 1000 × P_(kW) ÷ (PF × V_(V))

2,760 ÷ (0.85 × 24) = 2,760 ÷ 20.4 = 135.29 A

Equipment & Circuit Sizing

Breaker Sizing

Breaker ratings are in amps, not watts, so the real install answer depends on the equipment nameplate FLA, whether the load is continuous (NEC 210.19(A) sizes the conductor and OCP at 125% of a continuous load, equivalently 80% of breaker rating), conductor ampacity and temperature rating, ambient and bundling derates, and any motor or HVAC provisions (NEC 430 / 440). At roughly 115A on DC at 24V, the load sits in the bracket between a 125A standard size (non-continuous) and the next size up that covers a continuous load under 210.19(A) (around 150A). The actual install pick depends on whether the load is continuous and the factors above; a conversion page can't pick a single "right" breaker from the amp draw alone.

Energy Cost

2.76 kW costs $0.47/hour at $0.17/kWh (rates last reviewed April 2026). See breakdown.

Power Factor Reference (DC)

How the line current for 2.76 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	2.76 kW at 24V (DC)
Resistive (heaters, incandescent)	1	115 A
Fluorescent lamps	0.95	115 A
LED lighting	0.9	115 A
Synchronous motors	0.9	115 A
Typical mixed loads	0.85	115 A
Induction motors (full load)	0.8	115 A
Computers (without PFC)	0.65	115 A
Induction motors (no load)	0.35	115 A

AC Conversion Comparison

On DC, 2.76kW at 24V draws 115A. AC single-phase at PF 0.85 pulls 135.29A because reactive current is added on top of the real power.

Circuit Type	Formula	Result
DC	2,760 ÷ 24	115 A
AC Single Phase (PF 0.85)	2,760 ÷ (0.85 × 24)	135.29 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 2.76 kW at 24V?expand_more

2.76 kW at 24V draws about 115 amps on DC. Alternate cases at the same voltage: 135.29A on AC single-phase.

Is 2.76 kW single-phase or three-phase?expand_more

2.76 kW can be either. Residential loads up to about 5 kW (water heaters, dryers, EV chargers at 240V) are usually single-phase; commercial panels often serve the same load three-phase at 208V or 480V.

What is 2.76 kW in watts?expand_more

2.76 kW equals 2,760 watts. Multiply kilowatts by 1000.

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).

How does power factor affect the amps for 2.76 kW at 24V?expand_more

On AC single-phase, current scales inversely with power factor. At PF 1.0 (pure resistive, like a heater), 2.76 kW at 24V draws 115A. At PF 0.80 (typical induction motor), the same real power draws 143.75A. The extra current is reactive and does no real work, but still flows through the wire and the breaker.
