As RBuzz mentioned, that is a lot of power. A 2kw inverter is nice but at that rate of draw you will need to have a sizeable battery bank to feed it. ie: 2000/12= 166 amps That’s how many amps you would be pulling from a battery to produce that 2kw of power. I think you would kill most battery banks within a couple hours. First determine what you really need to run on inverter, then add up your total power requirements. This will tell you what wattage inverter you need and what size battery bank is required to feed it. You should also keep in mind that inverters consume a little power themselves. The bigger the inverter, the more it will eat in standby mode.
