Recently the price on inverters (esp true sine) has dropped quite a bit (there are two xantrex 1000 watt units the older 750 buck one and now the $200-$300 price one). Xantrex has a wonderful reputation. I own this inverter along with their older model (pro-sine) and also the new entry from sunforce (yes I have alot of 1000w inverters).

I also have alot of 1000w loads. In particular is my favorite testload a 1050 w (with motorthe heating element is 1000w exactly but it has a blower that consumes 50w so technically its a tad high).

With this dummy load both of my xantrex inverters will run it all day or until the battery bank dies whichever comes first. They draw about 110-115 amps on the 12vdc lines.

The sunforce 1000w inverter CAN NOT run this load for more than 2 seconds without an output overload shutdown. But I still like the sunforce because it can handle 900W and it has an RF keychain remote on/off switch.

The point is Xantrex products are clean, reliable power, while other knockoffs (compare sunforce's 1K and this one and guess who coppied who) are not up to being a real 1K unit. If anyone wants a demo my email is in my profile i'd be happy to film the two side by side on optima D31 blue top batteries and even give the sunforce the running head start with the fresh charge on the cells 2 seconds and it will shutdown. Yes, i know 1050 watts is over 1000w, but the xantrex will drain the batteries before they complain of anything else runing the heatgun.

This is the leading brand in inverters today. Their new product line offers 3x the value of their older units without sacrificing quality or stability. It's a real value in high power inverters. Unfortunately, xantrex moved their mfg overseas and the quality suffered from more than one report. We no longer use this model, but for an apples to apples comparison against offshore mfg inverters, xantrex still has a better design to begin with = better product to ship back to the usa

I'm not running much off this device and the thing that strikes me is that the cooling fan only turns on when a certain temperature is reached. So for small loads, it's very quiet because the fan has no need to turn on. Previous experiences with inverter default to the fan being on and they are often very noisy.

The sine wave seems to be clean. After trying this, I'll never go back to modified sine waves for devices remotely designed to work with sine waves. Otherwise, I'll just go with the cheap square wave inverters.

I plan on buying another unit in the future.

So far I returned (3) inverters (1)Power Bright PW400, (2)Tripp Lite PV1000 because the output voltage was to low (89-95volts). Fluorescent light would not be as bright,fan would not come up to speed and I"m sure this was not good for motors. Had this one for (3) days (Xantres Prowatt SW 1000) and am very satisfied with it. Output voltage is 124 volts, lights are bright motors are running up to speed And my running amps are lower. I don't know whether this unit is just made better or if its because its a pure sine wave inverter or both but it puts the other inverters I tried to shame.

I bought this inverter for long power failures. I wanted a way to keep my fridge running overnight when I can't run my generator (out of consideration for my sleeping neighbors). At first it failed to start the fridge using 8ga jumper cables on a set of golf cart batteries. I ditched the jumpers and hard wired it to the batteries using proper connectors and 2ga wire. After that it ran the fridge fine. The nameplate on the fridge says 1320watts, using a meter I found it to peak around 1200w with an avg continuous load of 250w. I've only run it for about 8hrs so no word on longevity, but it appears to be a well made unit based on fit and form.

I bought this about two months ago. So far I only use about 250 watts everyday 6-7 hours run time) and have had no issues at all. To test it I plugged in my 32" tube TV, two 60 watt lamps, two 15'6 notebooks, PS3 Playstation and the Frig. Ran it all just fine and took the surge from the Frig very easily. And more I'm sure! Well made product, great directions, easy to intall. I would recommend this to anyone looking for a well made power inverter that performs as advertised.
