Most small solar panels have low amperage and will not over
charge a wet cell battery. If they were used to directly
charge a dry cell battery, such as a C or D cell they might
over charge, but a wet cell battery with an AHr rating of 25
amps can be charged indefinitely at a rate of 2-3 amps and
you will be using the battery to run an inverter to power
various other loads.

This may be true for a few days of operation at a campsite, but overcharging
is overcharging, and it will eventually trash your battery. Take it from a guy
who ruined far too many batteries with cheap one-amp trickle chargers before he
learned. In general, solar panels need charge controllers for long-term
successful operation.
