Turn on inverter and your appliances should be powered!
JayGee
They have more than enough surge duration to start my hard starting appliances like A/C, microwave, air compressor, large power tools, sump pump, etc.

I have had numerous power inverters, most costing twice as much.

I have purchased many inverters for my service truck, RV, boat, and emergency home backup, and this is what I have learned...

Buying a large inverter is confusing. Most people want their inverter to run the "continuous" loads that they have, plus have enough surge power to start air conditioners, microwaves, sump pumps, etc. Seems simple enough, but when they purchase an inverter, usually it can't handle the startup surge they were hoping. Herein is the problem: most people don't understand "Surge Duration".

Most inverters can put out more than their rated "continuous" output for surge. But the question is: How long can the inverter provide that surge? The vast majority of consumer inverters can only provide surge for 2 seconds with most less than 1 second! This is totally inadequate for hard starting appliances. I have measured the surge on my 2 hp air compressor, and it lasted about 5 seconds before it settled out to its "continuous" wattage. My 1000 watt microwave settles down at about the 3 second mark.

So what to do? Always look for an inverter with a long surge duration. The bigger inverter companies sell them, but they are usually labeled "Industrial" or "Commercial", and are much more expensive.

Which brings me to the Whistler Pro Inverters. Whistler Pro's have something they call "Smart Surge Control" that provides the surge wattage for close to 10 seconds. That is the longest I have found of any low priced consumer based inverter. I gave several a shot, and they work as advertised! They have more than enough surge duration to start my hard starting appliances like A/C, microwave, air compressor, large power tools, sump pump, etc.

Before reading, this is meant as a review and not a guide. However, I put some tips that worked for me, but this doesn't mean they'll work in another individual's situation.

BACKGROUND STORY:
Living in the NJ/NY area, we don't see a lot of hurricanes or even tropical storms. Once in a while, Mother Nature decides to give us a taste of what one can do. Originally being from MA and also living several years in eastern NC, I've seen what damage they can do. I knew some type of backup power may be necessary. Without operation sump pumps in my basement, it would certainly flood. As Hurricane Irene came bearing down on NY/NJ expecting to arrive on Saturday night, early Thursday I frantically looked for a generator. Home Depot, Lowes, Sears were already sold out across the northeastern seaboard. As you can imagine, they don't stock a lot here. Then I had an idea. A POWER INVERTER! I quickly logged on to Amazon and looked for a 3000W that could handle my two sump pumps. I paid the extra shipping fee to guarantee arrival by Saturday morning. Sure enough it arrived when promised. THANKS, AMAZON!

Well, needless to say Irene hit my area with a massive amount of rain. Eventually our local substation flooded and I had no power. The sump pump wells started to fill quickly. Thanks to my power inverter, I was able to react! I hooked it up and got those pumps running saving my basement. I saved my neighbors basement too!

So what does this inverter do? Basically it inverts power from DC (i.e. a car battery, marine battery or deep cycle battery) to AC (110V) which your appliances need to run. In the case of the car battery hook up, your car acts as a generator (recharging batter via alternator when your car is running).

You really only need to know one thing when working with modified sine wave inverters; they will never be able to approach the rated wattage without some seriously fat power cables. You can't expect to feed Niagara Falls with a garden hose. If you want 3,000 watts out of this thing, you HAVE to give it plenty of room on the input. I use single ought "0" cable. Yes, it's expensive, but you're building a power system for 3 KILO WATTS! If you were running an electric razor, then you would be okay. This goes for the cigarette lighter inverter models as well. Sure, the manufacturer can put a sticker on the side that says it can provide 300 watts, but I guarantee the tiny wires the car manufacturer stuck behind the cigarette lighter in the dash will never be able to feed it properly. The best you can expect out of a typical cigarette lighter connected inverter is a little over 100 watts.

Okay, enough of that. About this specific model; it's usually quiet, but if you just set it flat on a table or on the floor, it's probably going to start making a weird buzzing sound. It's designed to be mounted. Once I mounted it on the wall, it was quiet as a mouse. You also have to provide it with properly charged batteries. Once the voltage gets down to about 11.9, it will start to have to work more and it will turn on the fans. Somewhere between 10.5 and 10.7 volts, it will start to chirp to inform you that it's about to shut off. That's programmed into the system to prevent you from killing your batteries. However, you really don't want the voltage to go below 11.5 volts because that's when battery sulfation begins. That's not good for your batteries. Look it up.
