A monocrystalline cell made from a single silicon crystal wafer is most efficient at harvesting energy when receiving sun at a specific angle. For this reason monocrystalline solar technology is generally preferred for large, hi-wattage fixed installations where sun tracking technology can be utilized.

A polycrystalline cell is made from different silicon crystal wafers melded together. This combination of cystals in a single panel more effectively harvests energy from scattered (partially shaded) or angled sun rays, allowing for more consistent power delivery under varying sun conditions.

OptiMate Solar portable chargers combine the natural advantage of polycrystalline technology with smart solar charge control, making charging of a battery safe and easy. Point the panel in the general direction of the sun and the battery will receive the most optimal charge, no further expertise required!


OptiMate Solar panels have solid aluminium frames with 4 robust corner brackets completing the construction of the panel. Each corner bracket has multiple mounting holes that can be used to affix the panel to a suitable surface, or the holes can be used to install the OptiMate suction mounts or an OptiMate adjustable stand.

The OptiMate suction mounts match to the mounting holes of the OptiMate corner brackets and are easily reversable. A small pull tab on each suction cup makes it easy to remove from the surface it is attached to. Suction mounts are included in the 10W and 20W travel kit. They are also available separately.


OptiMate 40W, 60W and 80W Travel Kits include an innovative adjustable rear stand that perfectly folds into the rear of the panel. Each ‘leg’ of the stand can be individually adjusted to suit the terrain, with a cross bar providing stability. Anchor loops are incorporated into the tips of each leg and two front mounted anchor straps can receive standard camping / tent pegs (not included in the kit), allowing the panel to withstand light to moderate wind.


The OptiMate charge controller is a fully sealed charger with a multi-step program that will save, charge and maintain the battery. The LED display provides charge progress information.

A solar panel will deliver power when it absorbs sunlight. A charge controller is needed to regulate the voltage so that the battery receives the correct charge voltage. The OptiMate charge controller automatically delivers a SAFE 24-7 charging experience, it cannot deliver power until it is correctly connected to the battery. Once connected and charging, no further supervision is required.


The OptiMate charge controller continues to show battery state of charge ‘at night’ or when no solar power is available. The indication mode changes from charge to monitor status during which the LEDs blink every 3 seconds. When it senses incoming solar power, it changes from monitor to charge mode.


The OptiMate charge controller adapts to the available power that the solar panel can provide and adjusts it to efficiently charge the battery. The controller automatically varies it’s charge rate between continuous charge at full sun and pulse charge at low light. This dual method of charging ensures that even during low light the battery will receive high current pulses of energy.

FAQ Solar Products

The OptiMate Solar - with standard controller - is suited for charging 12V lead-acid batteries.

The OptiMate Solar DUO is suited for charging 12V lead-acid and 12.8V / 13.2V Lithium (LifePO4 / LFP) batteries.

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.

OptiMate Solar - with standard controller - can only charge lead-acid batteries (STD, AGM & GEL).

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.

If the battery is sufficiently charged, LED #4 or 5 will immediately light together with LED #1 (flashing).

If the battery needs further charging LED #2 or LED #3 will light together with LED #1 (flashing).

The OptiMate SAE connection system is designed to work safely with vehicle electrical systems that have the negative of the battery connected to the chassis / ground. The controller does not activate charging until it senses it is connected to a battery.

The OptiMate Solar DUO controller works with 12V polycrystalline or mono-crystalline solar panels, with rated output from 10W to 60W.
