Power Considerations
WeatherHawk weather stations are provided with an integral sealed rechargeable lead acid battery that must be
recharged to assure continued system operation. The battery supplied with the WeatherHawk is a 0.8 AHr battery
which will operate the station for approximately 3-4 days without any external charging. WeatherHawk also offers
a 7 AHr external battery pack for use in higher latitudes and colder climates. To charge the internal or external
battery, WeatherHawk offers a solar panel option or an AC/DC converter option. If no power supply has been
ordered with the weather station, the user must provide an external DC power source with an output of 18 Volts @
1.2 amps.
Connecting an incompatible power source to your WeatherHawk voids your Warranty. Please check
with WeatherHawk Customer Service before connecting a power source not purchased from
WeatherHawk.
Solar Power
WeatherHawk offers a 5 Watt Solar Panel Kit for use with WeatherHawk Signature Series systems. The kit is
suitable for use with any WeatherHawk Signature Series weather station however, if the station location is near or
above 66° latitude, solar power is most likely not an option for recharging the internal battery of the weather station.
Locations near or above 66° latitude do not receive enough sunlight in the winter months to effectively charge the
internal battery using a solar panel. For these high latitude applications, the external 7 AHr battery is recommended.
AC Power
WeatherHawk offers an AC/DC Converter for use in recharging the battery using an AC power source. The ACP2
recharges the WeatherHawk battery by converting 110-220 VAC, 50/60 Hz power to 18 VDC. The ACP2 requires
the weather station to be located within close proximity to a source of AC power. The ACP2 must be installed in a
non-condensing environment or a weatherproof enclosure. The ACP2 is compatible with all WeatherHawk
Signature Series weather stations.
Communications Options
Direct Communications
Direct Communications with a WeatherHawk Signature Series weather station involves using an RS232 cable to
directly connect the WeatherHawk to a host computer. To do this, the WeatherHawk must be located close enough
to the host computer for a direct connection to be made. When using direct connection communications, it is very
highly recommended that an isolation kit be used to protect the host computer in the event of a lightning strike or
other electrical surge.
