This are AD files. I do not have time to test it. But it must work.

Here are my new control boards in gerber format, will add pdf soon... no one seems to have protel for the pcb to be read directly, but thats there too

Here is a screen shot, but a gerber reader on the gerber files will show it best obviously.

6984-0

It has a good current control system that works for torroids of all sizes, and have driven the main board up to 80 amps@240v to start 5hp induction motor on the lathe.... probably over 20kw surge I would think, my clamp meter was not fast enough to register more than the 80 amps... the leading edge would be higher I would think.

So easily starts drop saws, big angle grinders instantly etc etc.... will do a proper start to finish on how to build this one, as it seems to have all the bugs out of it, and is running quite a few households here, even on outer islands.

If folks want to make their own or get them made I will put up the complete gerber file set... I got them  fabricated from PCBWAY in china. I think
 Clockman will offer them singly perhaps.

Very nice Oztules... Always good when a plan comes together ;)

Fixed a hiccup in the screenshot attachment, forum was throwing an error and putting it at the bottom instead. Shows up in the body now. - Steve

thanks Steve.

Here is a mosaic of the control board for those interested.

Hi oztules,

Looks great.

Just a foolish question from a fool.

Whats happening here?.  ht 169SCR,  Any specific recommendations ? component values, speed, etc.?


 Just doing another OzInverter so will test out your New board, and have a few made up later.

I do like your testing proceedures........ personally speaking I just don't have the bottle. !!!!!!

Ac Coupling with the OzInverter voltage rise for shutting down the GTI's.

More AC coupling going in, second hand GTI's, so very cost effective way of controlling and using Solar .

The left hand SMA GTI needs for me to use my laptop to reset its internal voltage settings, its voltage shut down is presently just to high. The right hand SMA GTI behaves itself like it should.

But really the building is still a building site, but, but PV power is important...... must weld up that box section for the barn doors frames .......

thats a bt169 scr.... silk screen merges the bottom of the "b"
https://lib.chipdip.ru/140/DOC000140142.pdf
sensitive gate scr.

Yes, the death test can get exciting as you ramp up the power.... wondering when it will give out... I give up after the 5hp motor starts consistently, and decide enough is enough. I never expected it to drive this hard.

I am running just 16 fets ... HY4008.... small power board, which seems to be easy big enough for any application I have tried it on.

 I have decided to use the solar controller to control the grid tie via throttling too, just need time to get it built...... won't need to change much at all.

This is the one I use all the time for up to 120 amps or so..... will do more if you use heavy heavy wire.

Thank you Oztules for the information, will give it a go.

Your Solar controller GTI shut down looks interesting.

I will probably res-erect your GTI shut down circuit that you originally put together way back when.

Simplicity is the key, especially as folk around the World have access to all sorts/types of GTI.

Yes Arduino, Mega etc can be configured to see that the batteries are full and just operate a relay to disconnect the AC side of the GTI, but as I say folk out there may be not that savvy.

Below your old GTI shut down.

Would it be better to break out the charge controller and GTI into separate threads perhaps?
Just a suggestion, some great info here on the EGS002 board.

Hi to all i  have a Italian made onpower ups,  i made a mistake and the board control burnt. I would like to know if is possible use it as a power inverter puting a EGS 002.  The ups is very good staf it uses a toroidal transformer thats why itryng to keep it.If enybody has any idea  how to keep it working. Please help me. Thank you  to all in advance. Njm.

The egs002 or the 8010 circuits can use the transformer to make an inverter... but not a ups I'm afraid.

Any chance of a .pdf of this board?. RF ;)

Here are all the gerbers.... so you can have them made, or just print out the Gbl for bottom layer  etc or  drill holes, top overlay etc.

I use either Gerbview or now the viewer that comes in Kicad to view etc...... if I could get Kicad to use the gerbers to reform the pcb, that would be very nice.....
It would be too good to have a converter that took protel files to Kicad.

Been meaning to do a proper write up on the inverters now, but Clockman has done a handy job of that, so I have not bothered, but will some day.
I will firstly try to do a decent story that will make it easy to copy the control box that I now use for the solar charging...but time in an issue.

However I will try to get it done, and maybe ..... maybe.....
