PIP4048ms not connecting

[sa1g]

Hi, I've followed your guide, but I got no response from the inverter (output below). I'm using PIP4048ms, RaspberryPi 2B+, this cable (FT232RL chip) .

Are you sure it's connected to usb0? Try dmesg and lsusb to see what devices are connected

[sa1g]

I'm pretty sure it's connected to /dev/ttyUSB0 : dmesg: [63170.397891] usb 1-1.5: new full-speed USB device number 7 using dwc_otg [63170.554288] usb 1-1.5: New USB device found, idVendor=0403, idProduct=6001, bcdDevice= 6.00 [63170.554330] usb 1-1.5: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [63170.554351] usb 1-1.5: Product: FT232R USB UART [63170.554371] usb 1-1.5: Manufacturer: FTDI [63170.554391] usb 1-1.5: SerialNumber: A50285BI [63170.576156] ftdi_sio 1-1.5:1.0: FTDI USB Serial Device converter detected [63170.576545] usb 1-1.5: Detected FT232RL [63170.581000] usb 1-1.5: FTDI USB Serial Device converter now attached to ttyUSB0

Okay maybe I found the reason why it doesn't work: the cable is wrong ("the RX-DX and ground layout isn't right for this inverter" - form the forum, next phrase). In a forum a guy sent me this schematic about the connection from the inverter's RJ45 to a DB9. I'll make one by myself and search a DB9-USB compatible converter, hopefully it'll work. .

just add this: --porttype serial cable is ok.

just add this: --porttype serial cable is ok.

Is anything else connected to the inverter?

Have you tried the USB connection (does your inverter have a USB socket? )

No, nothing else is connected (only 220V, photovoltaic panels and batteries). My inverter doesn't have a USB socket.

[jblance]

Does the cable work with a windows machine and the supplied software (watchpower)

Tested, it doesn't connect to the inverter

[jblance]

Can you try different cables and adapters? Otherwise it may be an Inverter issue

Yes, I'll build the cable (as pic above) and use this adapter from DB9 to USB - a guy in the forum (the same who sent me the schematic) uses this and said it works perfectly, so I'll try with this. I'll tell you the results, thanks so much :)

[jblance]

ok, I will close this issue. Raise another if you have problems after getting a connection to work
