Hi all!
I recently finish the setup of a minimal off-grid system in the countryside. In a nutshell:
- 1x Growatt SPF 5000 ES (firmware: 040 05 701 - 041 05 701)
- 2x Pylontech US2000C
- 4x 540w solar panel
Everything working good (in terms of charging and electricity usage), and now I'm trying to monitor this setup.
* The master Pylontech battery is connected to a Raspberry PI 3 with SolarAssistant and I'm getting the expected data (using a USB <-> RJ45 CAN wire). ?
* But, the inverter (in theory) should provide data from the USB B port (printer USB type), but it doesn't. ?
I tried with 2 different USB (USB B <-> USB A) wires with:
- Laptop with Windows10 + PVKEEPER 2.0 (the COM port appear, but no data is shown...) (suggestion from SolarAssistant)
- Laptop with Ubuntu + Python ModBus lib. Still getting a communication error (using 9600 baud) (DIYSOLAR thread Github issue)
- SolarAssistant in a Raspberry PI 3. Connection timing out.
I'm a bit lost now, given I'm thinking that maybe the USB port is simply broken... I have not other ideas in mind and the USB A port (normal USB port) is not even providing connection (apparently is only for the Growatt WiFi dongle)
Any idea? Thank you so much. Best regards ?
