Exeltech XP1100
Exeltech manufactures the most affordable, high performance, true sine wave inverters. Available as either a 125-watt portable unit or a larger 1100 watt fixed unit, both feature sophisticated protection circuitry, making them able to withstand otherwise damaging overloads, short-circuits, and polarity reversal at the inputs. They are safe to use with higher voltage alkaline battery systems. Output is compatible with extremely sensitive loads, like high fidelity stereos, computers, and laser copiers. Efficiency is typically 85% at full power. The XP1100 is available in 12, 24, or 120VDC input and 120VAC output. The XP125 is available in either 12 or 24 VDC input and 120 VAC output. Both have a one year warranty for parts and labor.  More details
