Optimate Solar Duo Standard Kit 20 Watt 12V

The OptiMate Solar DUO Standard Kit, manufacturer part number TM522-D2, is a 20 W solar-powered charger and maintainer for 12 V lead-acid and 12.8 V lithium LFP batteries. Its separate OptiMate DUO charge-monitor controller is designed to charge and maintain the connected battery in daylight, while monitoring battery condition when solar power is unavailable.

The kit combines a weatherproof polycrystalline solar panel in an aluminium frame with a fully automatic charge-monitor controller. It is suitable where a mains-powered maintainer is not practical and the panel can be positioned for direct sunlight.
