Inverter wiring

I am planning to install a larger inverter in my RV. Currently have a small 400w unit but want to put in a 2,000 watt unit. Can I assume that I need to upgrade the wiring to the batteries? What size red and black wires are needed? Thanks.

You haven't mentioned the wire length.

The size of the wires you choose depends upon the current passing through them, their length, and how much voltage drop your inverter can handle at your max loads (bigger wire, less voltage drop).

Bigger is always better.
