[ANSS-netops] Solar power

[Jim Smith]

Mitch,

In the past for a temporary issue like this one we have simply kept extra batteries charged and changed them out at predetermined intervals (30,60 days etc.). However, this was only for a couple of sites and not a lot like what you may be dealing with.

> Many of our stations run on battery and solar and that normally works well.  We have a routine battery replacement cycle to make sure they don't get old.  Theoretically, we should be able to run with zero solar for about 25 days.  But this has been an unusually dreary winter in the southeast and we haven't had much sun for the past two months or more.  I'm wondering what others do in areas with limited sunlight to power stations that don't have AC available?
