Question & Answer
Q: What battery voltage can I charge?
The OptiMate Solar DUO is suited for charging 12V lead acid and 12.8V / 13.2V Lithium (LifePO4 / LFP) batteries.
Q: What type of battery can I charge?
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
Q: How to connect?
1. Solar panel cable
2. Controller input
3. Controller output cable
4a. O-01 Permanent battery lead
4b. O-04 Battery clips 5. Battery
Q: What are Monitor Mode and Charge Mode?
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.
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.
Q: When is battery charged?
If the battery is sufficiently charged, LED #4 or 5 will immediately light together with LED #1 (flashing).
Q: When battery needs charge?
If the battery needs further charging LED #2 or LED #3 will light together with LED #1 (flashing).
