This 140 watt 24 volt solar panel with a Tracer MPPT charge controller will keep your Deep Cycle SLA or AGM batteries topped off. This panel and controller can charge both 12 volt and 24 volt systems.
140 watt panel (see photo for specs): $80
Tracer MPPT with remote meter: $80
Both together: $140
The panel has a few “snail trails” due to its age but can still pull the rated 140 watts in full sun. It is approximately 58-1/4” x 26-3/8”.
Located in Philadelphia. Willing to travel to meet up with you within reason.

This setup worked great on my trailer for 6 years, and still functions perfectly well. I upgraded to LiFePO4 batteries and the charge controller doesn’t have a setting for that.
