Keep your 12-volt battery healthy and charged while your RV, boat, or trailer is in storage. Our solar maintainers provide a long-term trickle charge so your battery is ready for the next adventure when you are.
Build your own solar maintainer to extend your battery’s life and make sure you never find a dead battery before your next adventure. Choose from a variety of panel sizes and connectors to create a system that works for your needs.
For a full kit, you’ll need:
A panel (10-Watt or 20-Watt)
Our 8-amp charge controller
A connector cable:
For a Zamp sidewall solar port, use the sidewall port adapter AND either the 5-foot or 15-foot extension cable.
To connect straight to the battery, use either the alligator clip cable, the ring terminal cable, or the cigarette adapter cable.
*Optional: A set of mounting feet (magnetic or standard)
