Phred,
If you look through 'oztules' 60,000 odd words, you will see the W7 Powerstar Schematic, the PJ Power board is based on that. However, as you have already seen for the 'New 8010 OzControl Board' we need to change from 47r to a 5r6 resistor on all 24 fet's and parallel a signal diode, as the 8010 is a different purring beast to the PJ Control Board.
The Power board I am putting together is based on the PJ layout, as its robust, simple and okay for cooling installation. But there are several improvements I will make.
Obvoiusly, ....no SMD stuff to the board. .........I love through hole board components as they are good to work with as a DIY job. Soldering will have to be good. Where tracks go through the board I will use pins and solder each side. But fortunately there are not to many small tracks that require this.
I note that the PJ board has solder collars in most big holes to ensure good connections with some of the big connections, ie, 6mm hole for the 6 negative cables to the battery, FET legs etc. So if a connection is required on both sides with the component passing through then I will investigate further and amend.
My Mrs reckons I always over engineer, but with this Power Board it needs to be right?
Okay, As some of you will be aware, I have recently published a small A4 size, 76 PP, 151 colour photographs & 14 diagrams Booklett. "Making a Low cost, simple and robust 6kW, 50HZ Pure Sine Wave, 48vdc to 230vac, INVERTER." Its all in there, except these new Boards, which I will ad in as a pull out suplement with the first run of just 100copies.
Why did I do it, as there is no financial gain in these type of books.
1................ Up the Nose of the greedy ignorant Big Boys, especially SMA, its a long story!...
2............... With 'oztules' can do and will do direction, it is real and possible.
3............... Its 'Open source' type of publication. Like a famous Wind Turbine Man's publications, but remember I am just an apprentice constantly learning.
4............... Personal empowerment and self-improvement is very much our Philosophy here in Normandy, especially with real hands on cost effective renewable energy creation. Hopefully, I can pass on my experiences to other interested folk and importantly the next generation, especially my boys.
So in a few weeks time, when the bits come from across the globe, I will get the Mrs to put that extra page on our Web site for buying the book with everything in it, and the components lists & masks for making your own PCB's.
There is very little out there about the actual making stuff, and I like to believe that this small publication will inspire folk around the Globe to take another step.
I believe this is the first time that a Large, 6kW, 48vdc to 230vac, Pure sine wave 50HZ, Inverter has been manufactured and open sourced in this way.
However 'Phred', These forums have everything discussed and required to make a truly remarkable OzInverter, but remember no process should be skimped.
The OzInverter... summary... Get the silicone iron wound cores right, get the hand wound toroid correct, get the connections correct, get the cooling system correct, get the Boards in right...... Do it all properly..... and It will do 6kW for some time, that's if the batteries can take it, but it will also do even bigger/huge 15kW loads for a short time.
