With a bit of luck, somewhere on the solar panels will be a sticker and this should give you there wattage.
You will need a regulator and being a 24v setup, the panels will need to be the same.
I don’t sell solar gear and if you need to by a panel, get a 24v panel of about 10 to 20 watts and the you will NOT need a regulator.
With a small panel, you can connect it directly to the batteries and the panel will maintain your batteries indefinitely.
The panel is very cheap insurance for your batteries.

I commented that i disagreed i'm no electrical expert but even to me what he says doesn't make sense. I have a VSR setup when he basically implied that it wont link batteries until the 1st is fully charged and voltage is high enough.
Even i know that when your car start if the alternator works you'll have 14+ volts at the battery. Pretty obvious that a VSR cant sense a batteries state of charge, I don't understand how he can be so brainwashed to think that this is not the case.
My falcon daily has a "smart" alternator but it stills mainly puts out 13.3-.6 volts when hot. When 1st started its above 14v. To me this means a VSR would still work but maybe not aswell a as normal alternator.
Personally i can't see any real benefit to a DC/DC charger on all but the most convaluted battery system or one that has long cabling to batteries or you need a solar input.
Basically if you spent 100k on a landcruiser then you can probably afford the $600 or 800 on a fancy charger.
My cheap arse VSR does the job just fine on my cheap Land Rover
