Usually ships in 1 business days | | | | | | The Sunforce 11240 1000 W pure sine wave inverter is the tool you need to provide stable power to run a pump or mini motor that a modified sine wave inverter cannot. This is excellent for powering home appliances directly from your 12V battery; DC to AC pure sine wave. With 2000 watts of high surge power, this product is the perfect solution for power failure emergencies. 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. The 11240 provides continuous power of 1000 watts and has a 2000 watt surge power capability. Your purchase comes with a full product manual, and a DC/AC power inverter remote control modular connector cable and key chain remote. | | | |

 Not working reliably Jan 31, 2010
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.

Sunforce inverter Jan 24, 2010
Unit worked as expected. Would have liked not to have a remote control and it would have been cheaper. Remote control was worthless to me.

 It's OK for the price Sep 07, 2009
I've had the Sunforce 1000w inverter for a couple of weeks now. Like a kid with a new toy, I had to try it on a couple things.
1. Bass guitar amp - First thing I noticed was the static noise was a lot louder than when it was plugged into grid power. I guess the power isn't as clean as it should be for a pure sine wave inverter.
2. Rice cooker - It drew around 600 watts according to my Kill-A-Watt. The inverter cooling fan was turning on and off very frequently during cooking. When the rice cooker was done and went to "keep warm" mode, it was only drawing 40 watts but the cooling fan still turns on and off for a while until I unplugged it. I can see the fan turn on for any draw over 500 watts, but 40 watts???
Pros - It works. Cheap price. Cool remote power unit. Power information display panel.
Cons - Like other reviews, no way to mount it. Fan turns on at really low power consumption. The heatsinks are plastic and serves no real purpose. You would think if they used real heatsinks, it would've provided better passive cooling to minimize cooling fan operations. The big thumb screws for the battery power leads doesn't tighten good enough, better to replace them with nuts and washers from a hardware store.
I give it a 3 1/2 star.

Documentation all fine print and poor electrical connectors Aug 08, 2009
I received the 1000W inverter today. It looks heavy duty to me. I thought I'd read the instructions first before installation. The entire manual is in fine print, had to get out a magnifing glass to read some parts. The manual is in three languages, but not a lot of pages. I guess they felt that only experienced installers would be setting it up.
The unit has a 3 digit display, the manual shows the error codes that could be displayed, some make since, some don't. The manual shows an example of a 4 digit power load as 1380W. The panel shows this as KVA. Will have to keep the manual handy if an error code shows up.
The manual does cover all the important things that an installer would need to know. Anyone who understands the basics of electricty should be able to set it up.
When first connecting the groud wire the entire bolt turned inside the case, requiring me to open the case to tighten it up.
The connectors for the battery connections are too close to each other making it difficult to tighten them. The tightening nuts are designed for finger tightening and make it difficult to get them tight enough. The weight of a stiff 4 AWG wire was enough to losen itself with very little vibration. This could be a real safety issue. There should be some way to lock them down.
The unit also has a 12 V cigarette lighter socket which is powered even when the 120 V circuit is off. Too bad it dosent have it's own on/off switch. Due to the 120 V circuit's high self power consumption (2.5 Amps) of this inverter, I found this socket handy for plugging in my modified sine wave inverter for low power requirements thereby conserving the batteries.
The digital display shows the AC voltage until pressing a very small button, then displays DC voltage for 2 seconds then switches itself back to AC voltage display. I'd rather see the DC voltage most of the time or at least have a choice.
I was able to operate my big screen TV that would not work with a modified sine wave inverter.
