I am Definately of the belief that this is Pinched Nerves. I am quite aware of Back problems. I had a Spinal Fusion, Lower Back, when I was 27, after 2 years of Real Leg Pain from pinched nerves. But I have always been Careful since than, and I haven't done anything that should cause this. Now Working on Stopping it. I HOPE
KEITHH: The real problem with Lead acid batteries is maintaining a Controlled, Maximum charge voltage. The Charge voltage SHOULDN'T Exceed about 14.6 Volts in a cyclic use or about 13.6 volts in a Standby use.
IF that charge voltage is Maintained, Than the charge current Will taper off as the battery charges. No Problem
IF NOT, You have REAL PROBLEMS.

Thanks for your reply Gary. The more I look at this your idea of heating water and be darned to the batteries sounds better every day. My girl is complaining about the cost of wiring, then the electronic, then the batteries,,,etc...Maybe a smallish glycol tank with pump to circulate through small rad - fan combo...this could heat a small building ... I saw somewhere that the can govt was giving some grant funds to those who were going solar to water heating. That does not include wind....hmmm Well, maybe I can have a bit of both..a couple of cheaper car batts that are constantly topped off...no deep cycling..just lights perhaps or emergency power until we dig out the gas gen. Gary; with your injury I imagine any charge controller is in the future sometime, not to mention you are a busy man... Uh....regarding the inverter discussion, I have come across a big older type battery charger.. once I have its case opened I will see about using it in the inverter plans unless this is a no no. ..let me know what you think..maybe pictures will help.... Thanks Keith

Thanks Keith It would be more productive at this time, if you emailed me your phone number to discuss this. Typing is a Pain. Gary

I'm posting a circuit board pattern and component placement pattern for the solar/wind charge controller that I have been discussing in this thread. It's here for those who are interested. No replies are necessary. www.knottyaldermouldings.com/Circuits/pcb_pattern_for_charge_controller.JPGwww.knottyaldermouldings.com/Circuits/pcb_component_diagram_for_charge_controller.JPGYour have to modify your screen zoom to view properly. I'm putting together a parts list, including the printed circuit board, for sale to anyone interested. It might take a week or two as I am still trying to find the best prices on a couple of items. As I have stated in other threads, this circuit diagram is for those interested. It works, but I make no guarantee as to it's suitability for your particular application. Experimentors enjoy! Richard M.

I don't see Any PCB Diagram or Schematic with those links!
Just your Home page on both.

Be patient Gary. For some reason I could not get PNG files to work. Richard

This post is simply to move the thread forward from the depths of despair--In case any wants to view the circuitry I used. Richard

Nice design Gary. I will consider it in the future. So far, I have not had any problem with the relay. The auto relay can handle 30 A, but my circuitry is limited to 20A. When I am able to expand my array, I will have to consider a different approach. The way I see it, my current system is limited to about 20 A or about 400 watts incoming power. Richard

I designed this up to Avoid Relays and possible Contacts getting Stuck.
If you can find some High Current Diodes and Propery Heat Sink the Mosfets, its possible to handle MANY Amps. (And Mosfets can also be Paralled for even Higher Currents.)

My dad, during his working days, was a purchasing agent for General Electric. He received many parts on approval or for testing. I have in my inventory some high current diodes that could be used. And, of course, high current Mosfets are easily obtained. I am always looking for a better design for any problem and will resort to a new design down the road. Richard

Gary,
I would like to try your controller as I like the idea of getting rid of the relay. I beleive this would also be more efficient. I currently am running 4 panels 18v each paralleled for 13A at peak sun. The controller I made is similar to the one above & works just fine. I am using a 12V 30A relay.
My question is that I have no Primary DC loads. My inverter is connected to the batteries. With out having anything connected to your inverters Primary load point will this cause any problems? Would I just connect the Pos. of my dump load to your fet so I can connect the Neg. end to GND?
THanks, Kevin Harris
