Vector VEC051D 3,000 Watt D/C To A/C Power Inverter With Power Level Meter

I use this in my camper as my only power supply. It does the job great. They don't tell you that to produce that much power will take several batteries. I use three deep cycle and i can run everything except the power hogs (water heater, heater and air conditioner) for several days before i have to charge the batteries. The only thing i don't like about it is, it beeps when the power consumption is heavy and after 30 seconds it will shut off. The low battery shut off works a little to well. I have to run my charge system to get the amperage that it requires to produce 1500 watts or more for more than 5 minutes. Other than that, I love the fact that i can go camping where ever i want and will always have power. Running the refrigerator, T.V., and other small accesories is easy. And it will do that for days on one battery as long as you don't waste power.
