Question:
I have a horse trailer with electric tounge jack powered by 12v marine battery on board the trailer. Is there a solar trickle charger option to keep battery charged ? Trailer is used 3-4 times a year.

Hey Chaz! Yes, there are solar panels that can be used to maintain the battery on your horse trailer. The OptiMate Solar Duo Portable Solar Panel with Controller # MA69JR can be mounted with suction cups or permanently mounted to the roof of your trailer. It doesn't have a super high output but that isn't a major concern since you only use the trailer a few times a year. If you keep your trailer in the shade and would like an option you can sit out away from the trailer in the sun then the # MA56JR which comes with a stand would work as well.
What kind of horse trailer do you have?
