The outdoor unit uses a small solar cell to charge a small (but several
Farad) supercapacitor and a small battery. Battery replacement is easy,
repair/replacement of the supercap is a little dicey, but I was able to do
it so anyone could. Of course the company will repair it for you for $$$.
Normally these components don't fail for 10 years or more, but failure is a
possibility, especially out in the environment. But not a reason to avoid
the company and the products, they're about the best
non-commercial/industrial units out there.

Subject: Re: [TowerTalk] Wired Anemometer for Tower?
I had a Peet Bros. Unit and it was fine. I had issues with the physical
wiring (critters) and do went to a Davis wireless unit.
Be advised that the wireless units use a backup battery that needs periodic
replacement. That said, mine has never had any issues at all on my tower and
I shunt feed it for 160 m at 1.5 kW. It's about 15 ft below my other
antennas -- I've never heard it and it isn't bothered by me.

Can any of you recommend a wired anemometer or weather station unit?
I want to install an anemometer to monitor the wind speed at the top of my
tower. All I can find online are wireless units. On this reflector I
have
seen a number of bad reviews of wireless weather sensors, because their
little wifi transceivers get damaged by the RF from a ham antenna. I have
a
spare CAT5 cable at the base of the tower available.
