Your main battery would be a poor choice for main power for this... They are designed to give a big burst of energy very quick. Not great to draw a low level over a long time. Deep cycle batteries on the other hand are designed to do exactly what you are looking for. They can be charged solar and will run at that draw overnight. Remember though they take a longer charge cycle than your fast discharge battery. You are gonna need an isolator and look at it the same as an RV.

If you just need to keep beers cool there are many cheaper less complex less power-drawing options. You'd need about 300 Kg. of large storage batteries to push 7amps at night all night. You'd need a handful of 125 watt PV panels to keep batteries juiced. Is this practical or even necessary for your app? Maybe going in over your head.

P(watts)=I(amps)XV(volts) so 12v X 7amps = 84 watts power consumption. I hope this helps a little.

What is your power source? As it's a transporter unit, it seems dedicated to vehicle use. Thus you'll need to know the power supply options of your intended transporting vehicle.

If it doesn't shut off when reaching temp. then no you can't run 24/7 on a battery, it will drain to quickly. those you only run when you engine is running ( charging) . as far a solar goes it would take a good size unit to power that many amps.
