DIY custom inverter for power wall

This red inverter board was originally locked to 50hz, i swapped out the mystery controller (drive module) with a EG8010 board that happens to be pin compatible.

There are quite a few variants of this inverter board available on aliexpress and alibaba.

They are all designed around this EG8010 controller, the data sheet is here:

this effectively gives you the entire schematic for this inverter.

This red one is from here:

I got the EG8010 driver module here:

The blue one I got for testing/learning is here:

but it isn't as good as the red one which has better circuitry.
