This is a very nice quality Pure Sinewave inverter that runs everything I plug into it perfectly! There are only a few issues I that prevent me from making it 5 stars. These aren't a big deal for me personally, but might be a deal breaker for some, so read this before you buy.

The unit has automatic shut down features for low voltage (anything < 11.8V). This is a safety feature, and perfectly plausable from the mfg viewpoint, but it translates into the user needing a LOT of battery power to run a simple appliance for a short period of time. Also, DO NOT BUY DEEP CYCLE BATTERIES for this because they are designed to lose voltage quickly and provide current for an extended time. Putting deep cell batteries on this unit makes the problem much worse. I replaced them with regular tractor Lead Acid batteries, and they maintain a working voltage much longer. The problem is that you can't really drain your batteries even close to 3/4 charge before the unit shuts itself off... kind of a huge waste. It takes five 925 CCA LA batteries just to run my fridge overnight without tripping the inverter... and God forbid if it's cloudy the next day. So if you want to set and forget this unit, the auto shut off is really not for you.

They have another nice feature where you can set the unit to go into "stand by" mode which would theoretically solve the problem of the inverter itself draining all the battery power overnight. The problem is, however, that the once a second the unit turns on power, to sense load. Even though you can adjust the threshold at which the unit will wake from sleep, the momentary power applied to my appliances every second makes them all "beep" and the lowest setting (40W) is not low enough to keep the power ON long enough for me to activate the electronic controls on my washing machine... the unit kills the power before I can press "Start". It does seem to work OK for the fridge, but takes a second to light the bulbs when you open the door, and it's not enough to run the water and ice in door feature, which also is frustrating.

The answer for me is to install more and more batteries ($100 ea.) so you see the problem. If you want good mobile power on a job or camping site, there is nothing better, but if you want to run your home on solar power, this is not the unit for you unless you want to have 10 or more panels and 20 or more batteries... (>$5000 worth of stuff) and this unit is STILL under-powered for a whole house and only puts out 110v.

I will use this inverter as an emergency backup until I can afford the Aims 240V whole house inverter.

So in short, this device is great at what it does for camping or job sites but not for home solar unless you are running a small cabin on 110v only, and have many thousands of dollars to spend on batteries and panels.

Just got it in time for Xmas. up and running, it pass all my load test.

very clean power and stable.

Amazon should offer the remote control panel with the inverter.

now i have to buy it separately.

I have bought products from Go Power several times and they have been an excellent company to work with. I recommend them highly. The 3000 watt pure sign inverter has been in operation a few weeks and has not failed to do it's job. It is used to run our motor driven appliances such as fridge/freezer, furnace, washer, dryer and will run a swamp cooler and celing fans in the summer.
