The inverter needs to have a fuse and properly sized battery cables running between it and the aux battery. For a Prowatt 1750 watt inverter, Xantrex (www.xantrex.com) recommends a 200-amp fuse and 2-gauge battery cables if they are under 2-feet long, 1-gauge if they are between 2-4 feet and 1/0 cables for 5 foot runs with a warning never to use cables longer than  5 feet.

I just installed a 2000 watt inverter/charger in my coach and spent around $80 for a 300-amp DC fuse and holder.

I used to plug my solar panel into the lighter socket for my auxiliary battery. As long as current flow is low (less than 1-amp) you shouldn't need any type of charge controller to regulate the output of the solar panel.

I run a 100 watt amplifier for my subwoofer, a 5.6" lcd monitor, a VHS player, TV tuner,  rear-view camera, my Dometic refrigerator plus whatever is plugged into the lighter socket in my camper without any issues when the van is running.

The auxiliary battery setup that came stock in non-GL campers uses a 30-amp relay and a 12-gauge wiring to connect it to the starter battery.
