Formulas

DC: kW to Amps

I(A) = 1000 × P(kW) ÷ V(V)

1000 × 14.78 ÷ 24 = 14,777 ÷ 24 = 615.71 A

AC Single Phase (PF = 0.85)

I(A) = 1000 × P(kW) ÷ (PF × V(V))

14,777 ÷ (0.85 × 24) = 14,777 ÷ 20.4 = 724.36 A

Frequently Asked Questions

14.78 kW at 24V draws about 615.71 amps on DC. Alternate cases at the same voltage: 724.36A on AC single-phase.
14.78 kW is available in both, but three-phase is more common for commercial HVAC, rooftop units, and motors once you reach this range.
At 24V, this is Level 1 territory (120V AC, single-phase, typically 12-16A). A 14.78 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 14.78 kW of charging, you want Level 2 on a 240V dedicated circuit, not 120V.
14.78 kW equals 14,777 watts. Multiply kilowatts by 1000.
14.78 kW costs $2.51 per hour at $0.17/kWh (US residential average, last reviewed April 2026). At 8 hours/day that is $602.90 per month.
