Product Description
The Sunforce 1000 Watt Pro Series Pure Sine Wave Inverter converts DC power into clean, stable AC power. Excellent for powering home appliances directly from your 12V battery, this inverter will supply stable power to run small electronic tools, air pumps, electronic doors, small motors and refrigerators that a modified sine wave inverter cannot. Pure Sine Wave inverters provide clean power with very low harmonic distortion, no static or humming noise. With a peak surge power of 2000 Watts and continuous power of 1000 Watts, this product is the ideal solution for power failure emergencies and guarantees optimum compatibility with sensitive equipment, computers, motors, televisions and more! Compact and portable, this inverter is perfect for use at worksites, on boats, or for permanent use in a solar power setup. The 11240 features numerous safety features including an overload alarm and LED light, a soft start system, low battery shut down, DC input overload voltage, output overload, overload temperature, short circuit shut down, and a high speed cooling fan. Equipped with two 110V household electrical outlets, this inverter is so advanced that it is patented. Your purchase comes with a DC/AC power inverter remote control modular connector cable and key chain remote.Sunforce 11240 1000 Watt Pure Sine Wave Inverter with Remote Control Review
I bought the inverter to use in an RV to power lights, TV/DVD, and other light AC loads. The price on this unit is very attractive so I bought it and checked it out before installing. I tested it under light and maximum loads and even hooked it up to an oscilloscope to verify if it was really a sine wave output. The last thing I did was bring it in the house to power the TV, stereo, computer, DVD, and VHS player simultaneously. (This is still well under 1000W.)Conclusions:
(1) Powers all loads I've thrown at it without a problem (except see #4# including electronics, 1000W electric heater, fluorescent and incandescent lights, and an electric drill.
#2# Has a real sine wave output.
#3# Causes considerable interference to AM radio when used to power the stereo system, but absolutely no interference on the TV or FM radio or anything else.
Strangely, the TV guide function on the cable box stopped operating, but I can't be sure if the inverter caused this.
But the really bad part:
#4# It has unexplained shutdowns. This usually happens under light loading conditions. The unit shuts down and displays an error code of OST #overload# or 529 #inverter defective#. The unit was not overloaded #not even close) any of the times this has happened. And when it happens, you have to turn it off and wait several hours to turn it back on. I think it has to lose its memory of the error before it will operate again.
I will probably be contacting the manufacturer regarding this problem. The unit is no good to me if it doesn't work reliably.
