How do I charge 48 dcv from 24 volt solar panel?
I have four 12 volt batteries connected in series, and two 80 watt solar panels with a 12/24 volt 30 amp controller. What would be the most effective connections to charge the batteries?
Read the manual for your controller, which I assume is a charge controller. The better ones use a switch mode regulator so they operate over a wide range of input voltages and output voltages.
The manual should tell you what range of output voltages it will handle, and what the optimum range is. If not, contact the manufacturer.

You may have to connect the batteries in series-parallel for 24 volts. Why are they connected in series?
