Inverter

[sprinklerman]

This is a picture of our 17 mke looking through the storage bin drivers side. I want to install an inverter. 1 If I am correct all I need to do is remove the pannel marked inveter and find the wire and splice in the inverter. I asume all other wiring has already been done. I will eventuly have 400 watts solar and will only need to run the TV and a Kirig. 3 I plan on installing 2 AGM batteries. Would a 2000 watt inverter be to much ar to little also suggeations on brands

Thanks
