totals so far:

inverter power board: 2 (me) + 3 (KeepIS) + 3 (noneya) + 2 (disco4now) + 3 (johnmc) + 2 (nicks) + 1 (mrracerhacker) = 16

picoverter (this or something else is needed to drive the inverter board):
2 (me) + 2 (disco4now) + 3 (johnmc) + 2 (nicks) + 3 (KeepIS) = 12

mppt (needs a brainboard too): 2 (me) + 3 (noneya) + 2 (pd) + 3 (disco4now) + 3 (johnmc) + 1 (Andymc) + 2 (nicks) + 2 (mrracerhacker) + 3 (KeepIS) = 21

brainboard: 2 (me) + 3 (noneya) + 2 (pd) + 3 (disc4now) + 3 (johnmc) + 1 (andymc) + 1 (mrracerhacker) + 3 (KeepIS) = 18

I will get 2oz copper for the mppt and inverter power boards.
The other two will be 1 oz copper since they only do low power signal and control.
Everything will be at cost, plus postage.

I will provide support to get these things working.
Latest firmware, Arduino programming help, build questions etc..
All here in this thread.

I have removed the over current crap in the brainboard. It will not work
and it's best we do not rely on this poorly executed idea of mine for anything.

As far as I can tell, there are zero issues with the picoverter.

The inverter board had some errors in the top silk screen, I think I have sorted that out, and an error with the 18V zener layout. I think that is fixed too. (Both these are easy to patch up anyway)

Wiseguy's mppt board is perfect and works exactly as required. A small list of build instructions will be needed.

Maybe it's time to look at BOM for these?
