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.

Bought this off Amazon a month or two ago. I was looking for an inexpensive pure sine wave inverter to replace my Duracell (Xantrex) modified sine wave inverter. I was expecting to have issues from the get go (due to the cheap price!) but this inverter is working out quite nicely. I have it hooked up to 4 Trojan T-105 batteries which is charged up with an 85 watt Kyocera solar panel and Xantrex C35 charge controller.

Being pure sine wave, I can run anything now that my old modified sine couldn't. No more annoying buzzing sounds from CFL's or TV's. certain appliances that wouldn't power up on the old inverter now work flawlessly. Some things I run on the Sunforce: Samsung 22" LCD TV, CFL's of all sizes, Playstation 2, battery chargers, laptops, electric cooler.

I haven't tripped the over current protection yet at all, not even when using items that typically surge, such as a large power drill.

No fan issues like the other review mentioned.. in fact I haven't heard it come on at all yet; then again it's winter time here in Missouri so I assume it truly is thermal controlled.

The remote keychain that was provided with the unit works great. Since I'm doing the electrical work on our new cabin, I can turn off and on when working on the electrical. Then turn it off when we leave for the week.

The only issue I've had so far is once I came back on the weekend and the inverter turned itself back on sometime during the week. This normally wouldn't be a big issue except we're limited on battery capacity and can be a nuisance if kept happening. This has only happened the one time so no biggie.

The LCD readout on the front of the inverter is a nice feature, more expensive inverters don't have this by default, though I rarely look at it.

I have several 1000W inverters in my service trucks and thought the idea of a RF remote would be nice so I stepped away from my usual brand (Xantrex) Xantrex Technologies 806-1000 Prosine 1,000-Watt Inverter and their newer, more value conscious true sine inverter product line which is within $20 of this sunforce unit but lacks the features. This time I bought the sunforce.

First off, testing finished inverter installations, I use a 1050W load (it's a heat gun with 1000W heater and 50w blower). True, this is MORE than 1000W but all inverters have some surge capacity so it's never been a problem before. The sunforce unit's efficiency is within 1% of xantrex, requiring 114-116 AMPS at 12VDC to operate the 1050W load, however the sunforce will shutdown within 3 seconds with an output overload condition, while the xantrex units will drain the battery first.

I stepped the load down to 900W and things were fine, so I'm really going to overlook their slightly over-rated specifications on the inverter because my loads are in the 300-400W range and need clean power. Besides, the value proposition with sunforce's feature set is still there.

Another pro/con to consider is that the Xantrex units are metal cased with mounting holes, while these are plastic - that may lead you to some innovative mounting solutions, but it's not a big deal.

Neither Xantrex nor Sunforce has developed a "everything easy to read display" - my -806 model xantrex prosine comes close with a remote mountable on/off plate w/ lcd that shows volts, amps, and watts as a bargraph simultaneously.

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.
