Optimate 10W Solar Duo Pulse Charger, Tester & Maintainer

The Optimate 10W Solar Duo Pulse Charger, Tester & Maintainer helps you charge, recover, and monitor 12V lead-acid and lithium LFP batteries using solar power. It uses a smart controller that adapts its output to battery condition, with a polycrystalline solar panel delivering a pulse-optimised charge during daylight hours and an automatic monitoring function at night.Discover the key features of this charger and maintainer:Polycrystalline 10W Solar Panel: The 10W polycrystalline panel with an aluminium frame, four mounting brackets and a 2m output cable captures available sunlight and converts it into a regulated supply at 12V/12.8V, enabling you to charge a wide range of batteries outdoors while keeping the panel securely positioned on a wall, roof, or other fixed surface.TM522-D1 Smart Charger-Controller: The controller manages a six-step charging and monitoring programme, displaying progress through a 5-LED panel that indicates Test, Save, Charge, Optimise, Maintain and Monitor stages, allowing you to follow battery condition clearly while the unit automatically adapts to STD, AGM, GEL and LiFePO battery types.Pulse Charging Technology: The unit converts low-level solar energy into a 3 5A pulse current that increases charging efficiency, helping you maintain usable output in weaker light and ensuring that your battery receives consistent energy throughout the day.0.83A Maximum Average Charging Current: The 0.83A continuous charge rate supplied by the 10W panel supports gradual, controlled charging suitable for batteries from 2 40Ah, helping you maintain them without the risk of excess load.Automatic Day/Night Function: The system switches to charging mode when solar input is detected and changes to monitoring mode when no light is available, with an LED that updates every three seconds overnight to show you the battery s state of charge.Low-Volt Activation: The Save function initiates recovery from 4V, applying controlled current to assist you in restoring deeply discharged batteries that would not respond to a standard charger.Energy-Saving Dual Conversion: The electronics convert available solar energy through an efficient dual-conversion process that reduces losses and maximises the amount of energy reaching the battery, supporting reliable long-term maintenance.24/7 Maintenance Programme: The Maintain and Monitor stages work continuously to keep the battery at a stable state of charge, giving you ongoing support throughout changing light levels and overnight periods.Battery State Display: The LED panel indicates charge level and battery condition, giving you clear information at a glance when assessing the health of your system.Electronic Safety Features: Spark suppression, automatic shutdown on short circuit, and safe long-term maintenance protocols protect your vehicle electronics and allow you to keep the charger connected without risk.Weatherproof Housing: The IP54-rated controller and outdoor-rated panel construction protect against dust and water spray, providing dependable operation in outdoor environments and variable weather.Included Battery Leads: The kit includes an O-1 weatherproof battery lead and an O-4 clamp lead, giving you two connection options so you can attach the charger to your vehicle in the way that best suits your setup.This charger supports you in keeping your battery ready for everyday use by combining solar charging, low-volt recovery and continuous monitoring. Its multi-stage programme gives you clear information and steady battery conditioning, which is particularly useful when a vehicle stands for long periods. Adding this to your setup provides a practical solar-powered solution that works automatically throughout the day and serves as a smart choice for maintaining reliable battery performance.
