First I bought a small inverted thinking it will be enough to power up a big air condition and it failed. Then, I bought this humongous powerful inverter and at first it also failed. Their customer service is GREAT explain the problem. I was connecting the inverter with gauge 4 cables and it was powering up most stuff, but when it came to the 10,000 BTU air condition it failed. Then, they told me to change does weak gauge 4 cables and get gauge 0. After, that it was a beauty. This is hooked up with 2 106AH marine battery for now which I am going to put 10 in total. They are being charge by solar panels for now I only have 360 watts with gauge 4 wires, later I will put for 1000 watts of solar panels. Quick update, the A/C actually sucks about 4,600 watts for a good 10 seconds before it drops down to regular watt at 890 watts. Sense this thing actually is 6,000 watts and 12,000 peak there is no problem. With does 2 106AH marine battery it last just over 1 hour at night and 1h20min at night. UPDATE: After 3 years this unit has been still running!!!!! no problems what so ever! I bought Oct of 2010 is on 24/7 hooked up with 6 Deep batteries and they are being charged by solar power during the day. This unit I have it as a back up in case of any emergency and for any tool usage on the garage. I live in NJ and last year when hurricane Sandy hit I was with out power for 9 days, but lucky I had this BEAST power the entire house (frig, lights, TV ect) did not lose any food in the fridge and took all the stress for 9 days. As my solar isnt too big I just hooked up my car alternator to charge the batteries and did the job right. Will i recommend this to anyone? ABSOLUTELY!!! my next step is to put a ATS so in case there is no street power this will kick in on its on as is always ON just without any load to it. Then have another ATS that when my generator (finally bought one) gets turn on it will transfer to the generator on its on as well. I was running about 1,800 watts and with batteries of 6 big deep cycle jars (210 amps/hour each jar) it lasted a few hours about 4 to 5 hours.
