The name plate on the refer should give you all you need to know. Amp/hour rating for each power source is? Multiple that by 24. You have the amps necessary to run it for 24 hours. Amp/hour rating for each battery is? Since you do not want to draw a battery below 50%, half of the battery capacity is? Is that more or less than your refers draw? 125 amp solar panel should be OK for 2-12V batteries. But again, the rating of solar panels is kind of ambigious. That rating is based on full sun and tracking the sun. Since neither of those is really practical you really need to assume less output. Whether a panel can fully charge a battery or not is questionable at best. And based on how discharged the battery is.
