You also are also going to need alot of batteries to run the 2000WATT Inverter... This is a serious power drain install project. Hope you have picked out a PSW model Power Inverter so you can enoy all of your appliances to be able to use this unit with NO fear of the 'BLUE SMOKE' situation.
How many minutes will your battery bank last when around 170AMP DC Current is being demanded haha...
I am only pulling around 20AMPS DC Current for a continues time period using 4AWG size battery cables. My Power Inverter is a 600WATTs PSW unit which will draw around 50AMPS DC current if fully loaded down...
We decided we could live quite well OFF-ROAD with just a smaller 600WATT PSW Inverter. We can select almost anything to be operated sometimes only one at a time and only have to give up the Air Conditioner and High Wattage Microwave unit.
Hopefully some real time users of high DC Current systems will check in here... You can also download the install manuals for the high wattage POwer Inverters that should have this info for large wiring cables and large FUSE Block protection.
