It appears, from what I gathered from your last video, that we are doing the same thing with different approaches. The only difference is your using an external boost where I've incorporated the boost into the primary circuit. I saw your motor as the integrated boost circuit and tried to emulate its actions as it passed over the brushes by using a coil and directing it's flow. Interesting....

I have gone into the garage several times already this morning to see how its running, so far so good, very stable with a small fluctuation in voltages.
The inverter is pulling about 1.3 amps from side to side and the boost is pushing 1.5 amps back to the primaries. Lots of modulation from the inverter.
I doubt much of a gain over the long run but so far no visible loss in battery voltage.
I'll post again this evening.

One other thing that has occurred to me through the day is the difference in the signals. The inverter is pulling power at a certain rate in small surges to create an overall 60hz, and the boost circuit is returning it at another frequency. Not sure what that is though. Plus the boost converter is only sending current at 1 volt above the serial batteries voltage.
Everything is still running real stable.

Good video and idea
Matt,Originally posted by Matthew Jones View Post
Good video but as you said if anyone needs a circuit, and I do, you could draw one. Thanks btw.
Tried to set up a test run, but the shop heats up bad in afternoon hours. Will try again when cools down some.
Will head to Lowes for the 450 watt inverter. Will check for continuity between input and output before connecting to positives.
Almost ready,
Thanks again.Comment

Just adjust the output of the boost converter to about 1 volt above the serial bank. So if the serial bank is at 25.00 volt have to boost converter put out about 26v.Originally posted by wantomake View PostLast edited by Matthew Jones; 01-14-2017, 02:24 AM.Comment

Circuit
Matt,
Got it. Thanks so much. Will do a setup after the desert heat here in Oakway, South Carolina cools down!!!Comment

I decided not to make another clip of the same thing. I won't know for sure but I am pretty sure none of the batteries lost voltage. Not to say they didn't discharge at all, I would need to measure there capacity to know that. But I'll figure it out in the morning, the numbers and such. I'll run a test against it and see what regular discharge for the same period would cost.
What I did notice was the voltage of the batteries just moved around. At one point I had the serial batteries charging and then switched it several time just with a little turn of the screw.
Couple of days I'll do a bigger test like 100 watt or so, see if we can balance that out.
All that said I have noticed everybody and their mother is watching this thread. Like I said before its a simple enough thing to setup. More numbers and results that come in the better we can make this setup. but feel free do it from armchair if you need to.

As Usual
One or two building.
Three or four replicating with the WRONG parts.
Everyone else watching and waiting.
The only thing missing is the usual naysayers, but THIS time they are staying in the woodwork or THEY will look stupid.“Advances are made by answering questions. Discoveries are made by questioning answers.”

Same events
Matt,
The same in my setup. The batt1 is charging, but batt2 is slowly dropping one 10th of a volt each ten minutes or so. Charge batts3 holding steady. Only load on inverter is 15 CFL. Will post all the numbers later tonight. Letting it run.
After getting the inverter and boost converter balanced, then tweaking a little afterwards, the voltages stabilized.
Batt2 is one battery.
Batt1 is one battery.
Batt1 and Batt2 are in series.
Batt3 is in parallel with six other batteries. Solar bank no sun charging.
Inverter is 2000 watt.
Boost converter is 150 watt.Comment

Hi folks, hi turion, not sure who your replicating remarks are aimed at, though for me, i am not replicating at the moment, though i am making experimental observations that support what you folks are doing.
And that is this simple fact, when electrical current goes through a load, it is not used up like gasoline in a gas tank, it comes out the load ready to be reclaimed.
Maybe that's why i stated in my thread, this is a light hearted thread, for good reason.

Good or bad?
Well here is what it ran for 2 hr 20 min.
Time. #2. #1. #3. #2 & #1. Load. Inverter. Converter
8:45. 12.67. 13.31. 12.65. 25.94. 0.1 A. 1.6 Amps 5.3 Amps
8:55. 12.91. 14.13. 12.11. 27.06.
9:05. 12.85. 14.13. 12.21. 26.99
9:15. 12.81. 14.16. 12.19. 26.98
9:25. 12.79. 14.20. 12.20. 26.99
9:35. 12.78. 14.21. 12.21. 26.99
11:05. 12.72. 14.28. 12.02. 27.00
Load was CFL 15 watt at 0.1 amp.
Inverter across positives 1.6 amps.
Boost converter was pulling 5.3 amps.
Hope these numbers help. Will try higher wattage tomorrow with cooler temperatures maybe.Comment

Guys, I have nothing but respect for the folks who show up here and give it their best shot. I know some folks are using what they have because it is ALL they have, and some folks are waiting for parts and are using what they have while they wait. I have no problem with that AT ALL.
It is the guys who DON'T EVER try to get the right parts and yet insist that this doesn't work because they tried it with whatever they had and failed, and then spend the rest of their time putting this down when they never did it right in the first place. I have seen that countless times over the last eight years as I tried to get folks to give this a shot.
I don't believe that applies to anybody so far. No offense intended toward ANY of you who have been posting on your efforts. Some of you guys have posted lots of data, and I haven't posted ANY yet. I have run this thing so many ways in so many different configurations that my head is filled with numbers, and I just need to settle down and put together the basic setup again and join the discussion on how best to tune this.
That's my goal for tomorrow.

Well look here...Your numbers are OK but the point is to get balance so you have 1.6 amps going to the inverter yet you have 5.3 amps going back to the serial batteries. You should be able to turn that little screw on the boost converter and get that amp draw down.
Mine balanced out with just hair more current going up to serial batteries than was going to the inverter.
In fact all my batteries are at the same or higher voltage than they were when I started the run. Voltage is not capacity but its good indicator things are going in the right direction.
I'm going to move up to 100 watt load next and see what I can do about building a more robust simple (Maybe) boost converter to help tackle this job.
