Learning about voltages…

I picked up a few solar panels to tinker with while I learn more about solar systems in general. I also have a 80ah battery power station which a friend lent me while camping in the RV this fall. The panels don’t output the admittedly narrow power output requirements listed in the spec for charging the battery.

Is there a standard, economical way to step voltages down to a specific range, in this case from 48v (2 x 24v panels in series) to the 30-40v range the battery requires?

For reference, here’s the power spec for both:

[OUTPUT] PANELS: 24v 6.2a max power output

[INPUT] BATTERY POWER STATION: 30v-40v 10a max charging input
