OptiMate Solar DUO TM522-D1: OFF-GRID series 10W Solar 12V lead-acid and lithium Battery Charger & Maintainer

The OptiMate Solar DUO 10W (model no: TM522-D1) combines a weatherproof poly-crystalline 10W solar panel with the TM522-D charge controller to create a hi-efficiency smart pulse charger & maintainer for more effective care of your 12V lead-acid or LiFePO₄ (LFP) motorcycle or small deep cycle batteries.

How it works : The poly-crystalline solar cells work effectively with direct and angled sun, or with sunlight filtering through cloud, allowing charging in any weather. The OptiMate Solar DUO charge controller converts low current from the panel into effective charge pulses that work better at charging any type of battery.

With the OptiMate Solar DUO smart controller between the 10W panel and battery, the panel's output efficiency is raised to 50-100% (depending on strength of sun) generating a faster charge, with the controller regulating battery charge voltage to exactly what a 12V battery needs.

With OptiMate Solar Duo charge controller you can now leave your solar charge panel permanently connected to your battery - not only does it charges the battery better and faster, there is no possibility of overcharging!

And that's not all, at night the controller turns into a battery monitor, indicating the status of your battery. Come morning, even in cloudy weather, it turns back into a charger and continues caring for your battery.

10 WATT CHARGING POWER - Ideal for smaller 12V batteries capable of receiving 0.83A (average) charge current, as found in a motorcycle, small car, or with deep cycle batteries used in security or gate opener applications.

PANEL WORKS IN ANY WEATHER - poly-crystalline technology designed to work effectively with variable sun power.

PULSE CONVERSION TECHNOLOGY - Accumulates low current from the panel and converts it into efficient charging pulses ranging from 2A to 5A, never-mind the weather. High sun - more frequent pulses; cloudy skies - less frequent pulses.

CHARGER BY DAY, MONITOR BY NIGHT - Charge controller witches between charge and monitor mode depending on incoming power. You always know the condition of your battery.

Specifications:

• SOLAR PANEL RATING : 10 Watt poly-crystalline, with Vmp = 17V (Voltage at maximum power) and Voc ≤ 22V (Voltage open circuit - nothing connected to panel).
• CHARGE CONTROLLER OUTPUT VOLTAGE RANGE : 4V to 14.4V.
• PROGRAM STEPS : SAVE from 4V to 12V, CHARGE up to 14.4V, MAINTAIN between 13V and 13.6V, MONITOR (when there is no incoming power).
• MONITOR : 4 LEDs indicate battery state of charge.
• Universal 12V lead-acid battery Compatibility – Works with STD / flooded / wet-cell with removable filler caps (for adding distilled water) and sealed/maintenance AGM (Absorbent Glass Mat) or GEL.
• Lithium LFP/LiFePO4 12.8V/13.2V** Battery Compatibility – Automatically adapts DUO charging algorithm if Lithium LFP battery is sensed, including Lithium friendly 24-7 maintenance. Lithium batteries don't need continuous maintenance charging, OptiMate SOLAR DUO monitors the battery hourly and if it needs charge (below 70%) it brings it back up to 90% for extended life. (Lithium battery capacity and life reduces if kept at 100% when not used). ** nominal voltage is 12.8V (4 x 3.2V), but some battery brands claim 13.2V (4 x 3.3V).
• Safe for Sensitive Electronics – No overcharging, spark-suppressed and short-circuit protected.
• Plug & Play – Includes a set of battery clamps for quick connect and a fused battery lead with M6 ringlets that can be permanently fitted to the battery.
• Connect & Forget - Fully automatic charging and maintenance.
