    3-phase 380V inverter with EGS031 and EGP3000W boards

    Hi Roberto Thank you for the given information. As you said you must omit resistor to ground and short pullup to vcc and it works. Indeed there is problem with BET pin info in original datasheet. I have used 6v feedback transformers and its working without problem. Best regards Aljaz

    Hi, After some research I found if I short JP9 it goes to OFF state (1 blink/beep). Robmar, can you please give your jumper configuration? Best regards Aljaz

    3-phase 380V inverter with EGS031 and EGP3000W boards

    Hello, I have a problem with this device, I'm getting 4 flashes/beeps. As I translated it means undervoltage. I'm feeding inverter with 48V DC I also tried to raise rails to 60V with no difference. Feedback transformes are 220V/6V. Any idea where is the problem? Best regards Aljaz

    3-phase 380V inverter with EGS031 and EGP3000W boards

    Sorry, hello everyone :) I need simple 3-phase source for servicing equipment because my house have only 1-phase mains. So I found this pcbs on aliexpress and after some digging this forum. Normally I first wrote to the seller but I dont have many hope he will give me the documentation.

    I bought the motherboard and drivers board and they send me no documentation even chinese. Can anyone send me scanned documentation?
