Giandel GS-4000KAR 4000W Pure Sine
#19 in Over 2,000 WFull review
A low-cost way to get 4000 W on a 12 V system with GFCI outlets. It needs a very large battery bank and heavy cabling to make use of it.

3.0/5
A heavy-duty 3,000 VA inverter for a large van, boat or cabin that has separate charging and shore-power switching. Most buyers are better served by a MultiPlus 12/3000, which adds the charger and transfer switch.

- Can be paralleled or stacked for 240 V split phase
- Five-year warranty
Cons
- Draws 1.7 A idle unless search or AES mode is on
