I have been very busy the last coupla days and haven't had time to make comments to your comments, so I'll reply to all of you in this post

---you have put a lot of work and time into what your doing but the rewards are great. don't you think.---
My greatest reward so far was my Wife waking up late one night with the grid power off. She wanted to smoke a cigarette but not in the dark. She remembered the solar power in the livingroom and used the solar powered lights there, Then was thanking me the next morning.
---its funny but for sum reason i thought you might live on to of a mountain sumwhare.---
I am in the middle Huntsville Alabama USA. Population 275,000. The wind in Huntsville doesn't Blow, it Sucks.

---Want to get rid of that H.F. controller?---
The controller blew up 30 minutes after I hooked it up, I thought I would build another project out the the Chassis but  if you want it, I'll just charge shipping.

---After the pool goes in consider some water heating panels like I built. You can see them in my diary---
I looked in your diary but the picture is gone and there is not a description of the system.

Norm
---How's the wind and sun over there today?---
The last week has been quite Windy and Sunny. We had 3 inches of rain 2 days ago which is great since we are still in extreme drought.

---I have replaced many customers routers and modems due to heat from stacking---
Yes I am sensitive to heat from electronics too. The electronics in the picture was posed to look good. The modem has a Hot Spot on the bottom center, so I normally flip it on it's side so it can shed the heat easier. No vent holes in this modem.

richhagen
---I looked at the batteries and thought about the need for overcurrent protection there---
Yes you are very correct about some overload protection as close to the battery as you can get. I consider this to be the next priority in upgrading this system. The only thing protected right now is the main Wire Run around the house.
---I have also been thinking about grounding---
I have the negative lead from the battery connected to the ground of the Grid Outlet in the shed, also connected to the metal skin of the shed and the ground rod for the house.

ghurd
---Can always see if the cordless phone uses 9VDC, then solar power it with a 7809---
Wow, Powering the cordless phone from Solar had never occurred to me. The charger thing is right here on my computer desk and it is 9vdc. Does anybody know how much power a 7809 regulator pulls on idle ?

domwild
---Don't get caught sucking down some static electricity from the high-tension lines! I wonder if that is even possible?---
it is possible to get power from wire runs. We have talked about it a few times here. Search the Board for "long wire runs" and you will get some good information.

Many 1A and 1.5A 7809s claim ~8ma max, but seem to use about 2.5 to 4.5ma.

The phone(s) I have take very little power when charging (200ma peak?, and tapering down quickly), less when being used (50~80ma?), and not much at all when the battery is charged (20~40ma?).

And I have a junk "Olympia" brand that takes like 1/2 amp almost all the time. The batteries are always warm.

Too many phones to keep them straight, but most don't use much power.

Thanks Woof, but I already have 2 H.F. "blown up" controllers! LOL Too bad yours is though, you could use the 9v output on it for your phone (and/or a smoke alarm). That's was I was wanting it for. A friend gave me a box full of old cordless phones, and luckily, there was a 900mHz one in there that ran off 12v! I'm using an old Sealed Gel battery for my scooter that has a dead cell. It's only good for 10volts, but it has no problem keeping up with a good answering machine, the smoke alarms, and a life alert system all made for 9volts.

     Woofer, here's a link to my solar hot water setup.

http://www.thecasualtraveler.com/solar.htm

     Should work good for you in Alabama. I would like to use my HF panels with a 12 volt pump and battery to run the water thru the panels intermittently but I need to find a simple circuit/ device to run the system for 15 minutes on, and 15 minutes off in cycles and turned on and off with a photo switch. Not as good as running continuously but it would be 100 percent solar powered.

Traveler,

I'd like to find the same type of timer for my system, except 2 minutes on, 15 minutes off. I'm using a pump from Surplus Center, part # 2-924 that works pretty good. It only draws 1.8 amps on 12v, but it's not made for continuous use. Since it's a sealed unit & also made to be submersable, the housing could be drilled for some much-needed air cooling to prevent premature failure. Let me know if you find anything (cheap) for a 12v timer.
