needing an inverter capable of supplying pure sine 3-phase 380V 50Hz from either a DC source or AC single phase as well, I came across the EGS031 and companion board EGP3000W on one of the many marketplaces around.
I've gathered all the relevant schematic and datsheets (pity that most of them are written in Chinese, but this is when Google translator came handy...), ordered the boards, started sourcing components and got myself a custom made 3-phase transformer.
But soon I realized that, despite the fact that a good number of boards (judging from seller's statistics) have been sold, there's no trace around of someone having actually built the 3-phase inverter and willing to share his experience.
Soon after, looking around for further infos / hints I came across this site, and found some competent and active posters although this thread looks deserted from a while.
So, hoping that interest in this subject is still alive, and that, maybe, someone else embarked the adventure of building one or at least is planning to, I'm dusting off this thread, hoping to find some enthusiast to share ideas / doubts about this project.
My priority is to fully understand the right jumper configuration on EGS031 board. While some are obvious, other are not and having not yet completed the circuits, I look forward to get off on the right foot and avoid building a smoke generator
... Anyone answering the call ?
