Operation - Tecmate OptiMate Solar DUO Anwendungsvorschriften

OptiMate Solar DUO can charge and maintain the following battery types:
STD : 12V 'wet' cell / refillable lead-acid battery. Liquid acid can leak out if battery is turned on its side.
AGM : 12V sealed lead-acid battery, acid is fully contained within the battery. A 12V AGM battery holds a higher charged voltage than
STD lead-acid batteries.
GEL : 12V GEL sealed lead-acid battery, acid is fully contained within the battery. A GEL battery holds similar charged voltages to AGM.
LFP : 12.8V / 13.2V sealed Lithium Ferrous Phospate battery. Lithium batteries contain no acid. A LFP battery holds a higher charged
voltage than AGM / GEL.
Important - OptiMate Solar DUO is suitable ONLY for 4 series cell Lithium Ferrous Phosphate or Lithium Iron Phosphate batteries. DO
NOT ATTEMPT TO CHARGE any other type of Lithium battery.
When connected to a solar panel and a battery the OptiMate Solar DUO charge controller will automatically alternate between two
program modes, MONITOR (Night / no sun) and CHARGE (Day / sun), depending on solar panel's power delivery.
A. MONITOR MODE - When the solar panel stops delivering power (sun has gone down in the evening or cloud covers sun) the
OptiMate Solar DUO controller changes to BATTERY MONITOR mode and will now indicate battery charge level every 3 seconds.
LED 2, 3, 4 or 5 indicate battery charge level.

#4 blue (double flash)
#4 blue (single flash)
#3 yellow
#2 red & #3 yellow
#2 red
NOTES: A battery's charge level is directly proportional to the voltage measured across the terminals. Accuracy improves once the
battery has cooled to room temperature and has not received further charge for at least 6 hours or more.
Environment temperature affects voltage, the result will worsen as the temperature falls further below 15°C / 60°F.
Some batteries brands may have slightly different voltage and % charge parameters.
B. CHARGE MODE - LED #1 lights if the solar panel can deliver charge. LED #1 flashes when charge current is delivered to the
battery. Speed of flashing corresponds to current delivered i.e. fast means high current, slow means low current (cloudy
conditions or battery is not accepting high current).
LED 2, 3, 4 or 5 indicate charge progress whilst CHARGE LED #1 is flashing. If no battery is connected only LED #1 turns on.
