Greetings and Welcome!

In this case, the watts give us the important number. So if we take 130 watts, and divide it by 12 volts, we get the amps that it will draw per hour. That comes out to 10.8+ amps, so we'll just round that up to 11 to be safe. So if we multiply the maximum number of hours per day that you plan on using it by 11, we should know about how many amp hours per day it will use. You will want to get a car charger for it, so we can eliminate the use of an inverter, because they waste power. Whenever possible, we want to run everything on 12v.

Now, before we can figure out your whole system, we need to figure out what else you also plan on using, and then figure for a buffer so we know we're covered.

Charging while driving via an isolator, solenoid, or relay is always the most efficient way to charge your house battery(s). The next best choice would be either a generator or shore power, and contrary to what all the solar sales people want you to believe, solar is always the worst choice, and comes in dead last for many reasons. Provided we eliminate solar, everything gets much cheaper, simpler, and easier.

Cheers!
