Hello everyone.

Here are the photos of what I have - I had more then I thought, actually.

2x Toroids:









These only have ONE winding on them, so they seem to have had one winding removed already, and look to be ready to accept the chunky LV winding directly - I think.

3kW units, so good for up to 16A surge I would imagine - please comment.


Pre-assembled inverter board:







As I understand things, as of NOW, this board is no longer a good choice, mainly due to lack of robust MOSFET gate drivers, and so the MOSFET's can pop without too much abuse on these boards.  I am currently researching the "Picoinverter" controller paired with a Madness power board as suggested in the other thread I was linked to.


Other bits:





Diodes, couple of LED panel meters, LCD panel meters, CT's, 200A relays, 10,000uF 100v electrolytic's, fusible-link, my attempt at a current and voltage feedback module, and a bag of twenty HY4008 MOSFET's.

The mission-critical thing is the toroid's, and so with those, I am hopeful I can try to build something that works for the modest power requirements I plan to have.

Any and all comments welcomed.
