At full power this inverter draws 112.0 A from a 24 V bank and 280 A during a 6,000 W surge. That figure divides 2,400 W by 25.2 V under load and by 85 % efficiency, not the 94 % on the datasheet, because peak efficiency is not what you get at full load.
It is pure sine, so compressors, pumps and a CPAP machine run on it without the heating a modified-sine output causes.
Idle it consumes 20.0 W, which is 480 Wh a day if you leave it on around the clock. To a lithium bank, a battery cable of 0.5 m needs 4 with a 150 A fuse and 1.5 m needs 4 AWG with a 150 A Class T fuse; the fuse is the smallest rating above 1.25 × the draw that still protects the wire (ABYC E-11).

How this page was computed
Published efficiency is a peak figure, so current is computed at 85 %. Cable and fuse follow the checker: ABYC E-11 ampacity, 3 % drop, fuse ≥ 1.25 × draw and ≤ the wire rating, Class T for lithium.
- Manufacturer documentation verified 2026-09-15
- Battery datasheets BMS continuous and peak
The formulas are the same open engine the checker runs; the methodology page lists every constant.
These results are for reference. Wiring must be installed by a qualified electrician. Mobile installations follow ABYC E-11; stationary ones NEC 690/706.
