3. Technical specifications
(continuation)
The Ultrasonic Portable Solar wind instrument counts on
an advanced power management system so no external
source of energy is required beyond solar light.
The product has a solar panel integrated on the top that
feeds an internal, rechargeable battery located in the
interior of the product. Thanks to a laboratory-tested
sealing design, the battery is protected against any exter-
nal agent (water, dust..) reaching an IPX8 protection grade
rating.
The internal rechargeable battery cannot be repaired;
opening the product will permantly damage the sealing
and void the warranty. The battery can handle thousands
of charge/discharge cycles and its capacity and overall
characteristics guarantee a superb performance along the
life of the product. If fully charged, the battery can feed the
unit beyond 30 days in the absence of sun (>30 days on
continuous measureing in full darkness).
The useful life of the battery is 2100 full charge/dischage
cycles.
Battery life is 1 year in sleep mode without sunlight and
approximately 30 days while measuring.

Please note the solar panel has a protective film which
should not be removed.
3.4. Power
Advanced Power management
The Ultrasonic Portable Solar anemometer and wind vane
firmware automatically manages power drain, energy
storage, and solar production. The firmware sets one of
the following battery modes depending on the battery
status:
SAFETY MODE
· Battery level: 0% - 2,5%
· This is a safety mode to prevent permanent battery
damage. It does not receive or send any information and it
will not be visible via Bluetooth.
· Needs to be charged.
SLEEP MODE
· Battery voltage: 2,5% - 10%
· In sleep mode the device only provides advertising infor-
mation (BLE signal). It does not send any wind info.
· Needs to be charged
NORMAL MODE
· Battery voltage: 10% - 100%
Every mode changes automatically depending on the
voltage of the battery.
