[HCARC] question about repeater

[Harvey N. Vordenbaum]

Well, let's not get carried away with this project.  We don't have room for big honking golf cart batteries.
I have one sealed AGM or whatever type that's nice and slim.
I'll try to establish some current drain data, and then try it with the power supply and West Mountain Pwr Gate.
If it rains a lot we won't be able to get in there for a while.

Yes, I agree to a point, but since the solar part of the system is just for backup for hopefully a short period of time, the solar panel needed has plenty of time to perform battery charging.  It's akin to the solar setup needed for daily operation vs the solar setup one might put at a vacation house where it was only operated 2 weekends a month.  The requirements are radically different.  To determine what we would need to run the system full time off of solar would best be found by putting one of those plug in watt meters into the current system and see over a couple of weeks what our average daily electrical usage is.  That info tells you how much electricity you need to be able to generate.  Remember going solar, while it has an up front cost, eliminates the electric bill monthly so in effect it pays for itself over time.  The cost of solar is going down significantly over time.

Thanks for the lead to the local Golf Cart guys.  I'll check them out - the
225 amp hour 6 volt battery at Costco was $89.00 (two required to get 12 volts cost $178.00).  Since I have a standing appointment every tuesday in SA, the trip into town cost is negligible.
