picoverter so far:
I intend to stand the dc-dc converter on it's edge and hold it in place
with 4 solid copper wires. Strong as need be.
The board is only 75mm x 115mm approx.
here is the schematic
The dc-dc converter takes the 48V battery (46 - 56V) and makes 15V at about 1 Amp.
1 amp is needed when both fans are running.
I use 3 diodes in series to drop the 15V to about 12V sort of ish and that
is good enough for the fans. Saves using a 7812 regulator and more caps.
This is based heavily on TinyT's work on the nanoverter.

This controller will be perfect for workbench testing.
Probably use it in the spare inverter builds in the future.
