T107 Weather Station
amp-hour battery to 80% capacity (5.6 amp-hours). Discharging the battery
past this value could result in damaging the battery.
Polling the station once every 10 minutes and staying on line with the station
for one minute consumes approximately 1.276 amps over a 24 hour period. If
the station were to lose power it could run for around 4.3 days (105 hours)
before damaging the battery. A station with a 10 watt panel would need at least
3 hours of sunlight every day to keep the battery charged. Recommendation
here would be to decrease the power output of the radios or add a PS24 power
supply and enclosure with a 24 amp-hour battery below the main enclosure.
See Appendix B,
PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure
, for
mounting options and information on the PS24.
Polling the station once an hour and staying on line with the station for one
minute consumes approximately 0.388 amps over a 24 hour period. If the
station were to lose power it could run for around 14 days (346 hours) before
damaging the battery. A station with a 10 watt panel would need at least 1 hour
of sunlight every day to keep the battery charged.
