i would like to help

[Thorbijoern]

Hi,

i'm researching inverter design for some time now, because i noticed a lack of open source inverter projects. There are open source MPPT charge controllers and BMS, but no inverters. I only recently found this project but think your work is great! I have documented a lot of stuff i found about inverters here: https://thorbijoern.github.io/wiki/#inverter%20(Wechselrichter) maybe it is helpful to you (i need to do some ordering though). I would like to contribute to this project, because the goal of my researching was to create my own design, but i still have a lot to learn. My electronics knowledge is limited and i haven't done anything powerelectronics myself yet, but i think i have a good overview. The main point where i'm stuck with my researching is the boost stage, which steps up the voltage from 12/24/48V to the required high DC voltage (around 300-400V (230V RMS is 325V peak in europe)). The inverter h-bridge itself is an easier part it seems.

i've only read a small part of the documentation as of yet, but in #1 you said you would need help on the software side (even though it's from 2016). I'm a software developer by profession and could help you with that part.

this project also intersects with the projects from https://libre.solar/ and https://www.ose-germany.de/ (https://wiki.opensourceecology.de/Open_Source_Ecology_Germany) and others and compatibiltity/interoperability between the designs would be great.

Thank you for the great work so far!
