What’s your budget?
If you want to really improve your battery charging, prioritize the solar over the alternator input, and improve the charging performance over what the alternator can do on its own, instal a DC-DC charger that has both alternator and solar inputs.
A further benefit of the DC-DC charger: If you have a 3-way fridge, the DC mode will work noticeably better due to the charger maintaining the voltage at 13.5-14.6 volts vs 12 or less without it. It surprised me when I discovered my fridge DC mode actually worked after installing mine. A 25-30 amp DC-DC charger can do that all day long, drawing power from your solar panels when it’s available, and the alternator when it’s not.
