At full power this inverter draws 466.9 A from a 12 V bank and 934 A during a 10,000 W surge. That figure divides 5,000 W by 12.6 V under load and by 85 % efficiency, not the 90 % on the datasheet, because peak efficiency is not what you get at full load.
It is modified sine, so the checker warns against motor loads on it: Microwave, CPAP machine, Blender among the appliances in the catalog.
For scale, two 100 Ah lithium batteries (2,560 Wh usable) run it at half power, 2,500 W, for about 0.9 hours. Idle it consumes 12.0 W, which is 288 Wh a day if you leave it on around the clock. To a lithium bank, a battery cable of 0.5 m has no gauge in the table that carries it and 1.5 m has no gauge in the table that carries it; 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, 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.
