  2. I have just installed my rasberry PI and connected it to the Axpert inverter lsusb seems to show the device [email protected]:~ $ lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 0665:5161 Cypress Semiconductor USB to Serial Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub [email protected]:~ $ However there is no mapping to a usb port in /dev/ttyUSB at all. From what I understand there should be? I found this article https://community.cypress.com/thread/30
  3. I am also looking at developing something myself as I am just looking for basic monitoring and not filling with any inverter settings remotely or anything like that. Then I could also send myself notifications around various states such as battery voltage. I have worked on linux for a long time and have done a lot of bash scripting and a little bit of perl but never worked with python. From the scripts I have found on github to communicate with axpert most seem to use python but also be a lot more involved and have options for changing inverter settings. Does anyone just have
  4. Thanks very much for the reply I hadn't decided yet. It's just to tinker around and do some basic monitoring so I didn't want to buy something like ICC I read a bit about watch power but doesn't sound like I can run it on raspberry Pi So I was looking at this https://www.playbackdesign.com/pd-axpert/ I am definitely open to suggestions though.
  5. Hi, I wanted to use a Rasberry PI 4 and connect to my Axpert VP 1K/1000W inverter for basic monitoring My invert has the following communication ports on the side (attached pic) Which do I need to use for monitoring? Or can I use either one? I received a serial to ethernet cable (attached pic) with the inverter which I assume I could connect to the ethernet port and then use a serial to USB converter to connect to my Rasberry PI? Otherwise can I use a standard printer USB cable (attached pic) to plug into the USB port and directly into the PI? Thanks very
  6. Thanks very much. That is what I suspected, I just need to be sure.
  7. Looking at my manual with the last screenshot it seems the charger is PWM The 150W panels are also 15-18v which is why I thought they would be better. Fewer panels to install to get more power. Also I already have one of these 150W panels. So as long as I stay within the 15-18v, does it matter what wattage the panels are? I assume as long as the combined Amps are less than 50A then I'm fine?
  8. I seem to have a different axpert version. Mine is a 1000W 12v version This is the specs from the side of my inverter as well as from the manual. I assume the 85W panels in the manual is purely as an example to show how to calculate how many panels you can run in parallel to not exceed to 50A max. I assume I don't actually have to use 85W panels and could instead run up to 6 x 150W panels with pmax current of 8.3A in order to be within the 50A limit?
  9. I just wanted to ask a question. I have a Axpert 12V 1KW inverter currently grid linked for load shedding backup. I am thinking of expanding for solar backup if load shedding stage escalates and the time between shedding is maybe not sufficient to charge my batteries fully or if I decide I just want a longer backup for weekends. The manual for the inverter mentions 85W panels and connecting 10 in parallel. It does not mention a max solar wattage. I assume this is simply an example and I can use any size panels as long as I don't exceed the 50A and I make sure I have 12V panels connected i
