Re: Solar SG

Richard,
When using the SG to charge batteries with solar panels, you must match
the impedance of the panel to the SG.
To do this you need capacitors at least 20.000 uf 75 volts we run the
SG all the time this way. Set the SG to pull over 1 amp of current by
setting the base resistor. the next question, is it a multi-coil
machine, if so set it to pull over 5 amps min.

Thanks Aaron! I know in the FG book on page 46 there is some thing about them, i am still waiting for my copy.

Ash

Im doing some tests with a solar added to sg setup with magnifying glass over the solar panal (tricky to set up) ... I havent enough tests to post results yet but when i do i'll post them in (proberly 2 weeks from know)

Hi Ash,

In Free Energy Generation? In my copy on 46 is a schematic but no reference to Solar. It has been a while since I studied the book word for word and don't recall off the top of my head about solar references.

OOOoops. I think it may have been page 49, ill ask a friend who has it to check for me. I heard the Multi coil solar co generation Bedini set up was described the book some where, which seems very productive and practical , i think it is up to use to build a multi coil even if its solar co generative, as we know Johns hands are tied , as is seen in energy from the vacuum 2 where they ask him, would you sell this system and he replies NO.

I could make a Fan kit solar system right now, one battery in with solar charging, and 4 being charged with a relay, seems we should be making an effort to utilize whats there, i am sure NO solar system in the world has a system where one solar panel can charge 4 bats. Soon as battery umber 4 is conditioned ill upload the fan kit and solar system with the relay and do some tests.

Ash

I've believed for years that a solar setup to keep an input bank topped off during the day is a great system and I don't consider it cheating.

WHATEVER WORKS!

Harbor Freight has a great deal on a solar system now: Harbor Freight Tools - Quality Tools at the Lowest Prices

The price on the site is over $200 USD but the current newsletter is $179.99 USD...seems a good deal considering I paid about $90 for 1 single cell about 12 inch wide and 3 feet long...12v 1 amp about 7 years ago.

I used to use that cell to charge up a 24v bank of (2 12v batts at 1.7ah each) that went to an electric scooter. I just got it running a couple days ago but wiring seems a little screwey...works fine on low speed throttle but when I gun it...it bogs down with me on it...those batts I'm trying to charge on the stock charger after having been charged with different SG type circuits for the last 7 years so maybe it is just filling up the holes until it gets real hot current charge...anyway, will post if anything is worth reporting.

If you have a charge controller it will cut the voltage down as soon as it reaches about 14 volts. If the parts of the circuit can handle it I would remove the charge controller and run the panel straight into the circuit. an open circuit voltage on many panels is 21 volts with no load, so you should get somewhere just below that. I have been running solar panels on my van for the last 10 years and never used a charge controller. I just monitor the battery voltage with a meter and switch out some panels when it gets too high.

Hi All,

I have a 30 watt solar panel, putting out 22 volts in full sun.
However, it will not run my 6” fan energizer.

Maybe it doesn’t have enough amps.

What do you think?

Carl

Did you test it with a wall power supply to see how much it draws? It is good to test there to get an idea... first..

Where did you get your 6 " fan? Sounds idea...

mart

Hi Mart,

Bought it surplus.

Trimmed it down.

Mart,

The fan draws .420 ma wall power.

My 9ah LA ATV battery is conditioning.
Charges from 12.5v to 13.5 in 12 hours, draws down in about 12 hours using 60 ohms.
Charge time is getting shorter and draw down is getting longer. :-)

Nice...

This thread has lain dormant for too long.

I have more questions that need answers.

I have 2 15 watt PV’s………I get 22 volts in full sunlight……….They will only drive my SSG in full sun.

I have tried them in parallel and series

How does one manage to deal with varying voltage caused by varying sunlight?

Carl

SSG get energy from the source in pulses, and so send energy to target in pulses, my first run in my Bedini, ran very well with 12 volts power source regulated, but when I tried feed it with 9 volts batt, don't worked, then I put two 9 volts batts in series and ran slow, but when I added a big capacitor with batts in series, ran very well and fast. drawing 200 ma only. Then you SSG need a minimum voltage to run and minimum amperage to get the source, for get to work with solar cells you need a big capacitor to feed your SSG when work you must tune it again. Another form is converting your solar cells in a power source, for example if you get 22 volts in full sunlight, and 10 volts in foggy day, you can use a voltage regulator 9 volts, with high capacity capacitor, then you can tune it well to work using 9 volts.

I used a capacitor electrolytic polarized 220uf x 200 volts. in paralel with source, Capacitor is get charged, and keep a reserved good energy to feed coil in precise moment that is needed.

Thank you Patmac,

It is working just as you describe.

The sun is now running my SSG up here in Canada.

Do you have a schematic for voltage regulation?

Carl

This is a simple schematics for get 9 volts for example in way stable. You can get 12 volts changing 7809 by 7812 for example, or 7824 for 24 volts, series 78XX is very wide.



C1 1 1000uF 25V Capacitor Elec
C2 1 10uF 25V Capacitor Elec
C3 1 1uF 15V Capacitor Elec
C4 1 0.1uF 15V Capacitor Elec
U1 1 Regulator chip 7809
T1 1 TRansformer 12V, Cell in your case.

This are the rules:

7809 like this support 1000 ma max using heat dissipation, output is 9 volts but, input must be 12 volts min for get 9 volts in the output with good stability, you get 9 volts very stable in voltage and amperage. But if input is 22 volts for example output is very stable in 9 volts. Input max is 35 volts aprox.

7812 obviuously need about 15 volts to sustain 12 volts in output.

There are others ways to get output stable like zener diodes, but need to know some about electrics deeply and can be problematic because cells vary too much.

Last option can be by using battery, battery is kept charged with cells and you get energy from battery, the problem is build a charger control for the battery because charged so much can to explode, and discharged so much get damage. Obviously the way more indicated is yours, only with cells run your SSG it's GREAT. And recharge battery very efficientely without use a source battery is better.

Good luck.

Thank you for your help.
Is there something I can do for you?
Maybe send you a component/parts you are having trouble obtaining in Colombia.


Carl

Hi, I,m brand new to this forum but I have been visiting here for months and decided that it might be time to join so that maybe I can learn more and perhaps contribute something. My interest has been the Bedini SSG. I have been trying to find a way to use it on my boat with solar panels to help charge the onboard batteries. The work that I have done is posted on Youtube here YouTube - Lidmotor's Channel. I also have been experimenting with HHO and the Bedini. Thank you to all the people who have shared their knowledge so that I could do this. What I found out about running an SSG with solar power is directly in line with what is posted above. The only other thing that I can add is to try an adjustable switching regulator to control the voltage. Theremart and I have had great success using that voltage regulator. Run the solar panel to a 12 volt battery and then put the switching regulator between the battery and the SSG. If you have a panel larger than 5 watts you will have to use a controller before the battery to keep from over charging it.

Hi Lidmotor,

Can you give us more info on this switching regulator and it's function?

Carl

Hi Carl, I found this thing by accident when I was reseaching voltage regulators for my project. I am very inexperienced in this area so I just took a chance that it would work. It works well for what I needed. It is called a "step down adjustable voltage regulator". I found it at Demension Engineering .com. Part # DE-SWADJ. Cost was $15 US. The item is also called a linear voltage regulator. It is 90% efficient. The one that I am using is adjustable from 1.25volts to 10volts and can handle up to 1 amp. Mart got the next size up fo his projects but now is trying the smaller size like me. Both of us have had trouble with burning them up by not being very careful with hookups. They do not tollerate high voltage zaps from capacitors or shorting. I'm on my 4th one. Mart is on his 2nd. The Bedini SSG really likes what comes out of it. It has a small adjustment screw that lets you control the power coming in. You get hooked on it real fast. Its like an adjustable carburator for the SSG.
