3) Charging the Solar
Charging the Solar
The Solar is equipped with a rechargeable lithium-ion battery, powered both by its integrated solar panel and by a USB-C port.
Solar charging
The integrated solar panel allows the battery to be automatically recharged when the instrument is exposed to natural or artificial light.
Under normal outdoor use conditions, this charging significantly extends battery life and reduces the frequency of USB recharging.
For optimal efficiency, position the Solar so that its solar panel is exposed to light during flight or during storage.
Solar charging works even when the instrument is turned off.
USB charging
The Solar can be recharged using a USB-C cable, by connecting it to a computer or a standard USB charger.
The orange LED indicates the charging status:
orange LED with slowly varying intensity (wave effect): battery charging in progress
steady blue LED: battery fully charged
A full charge takes approximately 1 hour.
Battery life
Battery life depends on usage (volume, sink alarm active or not), Bluetooth connection and exposure to light.
Thanks to the integrated solar charging, battery life (≈50h) can be significantly extended under normal usage conditions.
Recommendations
To preserve battery lifespan:
avoid leaving the instrument exposed to extreme temperatures (for example under a car windshield in direct sunlight),
recharge it at least once a year via USB if you do not use it for a long period,
