I'm planning to install two PIP 5kW inverters in parallel mode, in which there will be one master and one slave inverter - the master will command the slave by it's own.
Can I still use the solar-pip commands, controlling the master unit, or I will need other type of command, does anybody know and tested?
Solar system system running on Raspberry pi to monitor, graph and manage your home built solar system. Supports several BMS types and have all key features like MQTT, Node-Red, Influxdb and among other stuff. Its also built so you easily can add more software thanks to SensorsIOT
However, I came across some doubts and at the last step of the manual I had an error.
1st: Can I use my inverter with the solar system 2.0?
I use three-phase at home so I have 3 off-grid inverters (I only have 1 connected to raspberry pi 4 to test, for now).
This is the link of my inverter: https://pt.aliexpress.com/item/3296...u&albcp=12838283515&pvid=53d59f51-d235&nstaff. = 539263010115 & TERMINAL_ID = 451034c810174cf38ee70cee39f0563c & needSmbHouyi = false & albbt = Google_7_shopping & src = google & crea = pt32969834923 & aff_fcid = 42adbc92fe1b4d429f2c1735f974e904-1622662366688-05671-UneMJZVf & gclid = Cj0KCQjw2NyFBhDoARIsAMtHtZ48XAjvtXUKemg7vvCOFd1FOdKcXrtwo4NAXKUpL9fu_EBmHr2Tu5EaAv6gEALw_wcB & albag = 122 319 359 998 & aff_fsk = UneMJZVf & albch = shopping & albagn = 888888 & isSmbAutoCall = false & aff_trace_key = 42adbc92fe1b4d429f2c1735f974e904-1622662366688-05671-UneMJZVf & RMSG = do_not_replacement & DEVICE = C & gclsrc = aw.ds
2nd: Can I use the usb port to connect to the raspberry pi 4?
3rd: I did all the steps of the manual, I think everything is correct but at the last step when I had to choose the example “cd solar-sis/example“ I didn’t know which to choose but I chose the “PIP4084“, was it right?
When I ran “npm install“ it showed me the following error:
make: *** [crc16.target.mk:107: Release/obj.target/crc16/lib/crc16.o] Error 1

I cant check your link. Please post a proper link.
If its a PIP you have that use that protocol you use the one you mentioned. If its something else you might have to write your own protocol file.
The install should be run in the main folder if not mistaken. Not in the example since its "Examples" on how to configure it.
but I had another problem in the last step running the “node project.js” =(
“If all works out fine you can now run the software. Dont forget to configure it first in session.json where you set the port and the server to send the data to.”
In this step I don't know what to do, how do I find the port? ( is it my usb port? if yes how can i see it? )
(" i change "serial_port": "/dev/usb/hiddev0", (is my ubs ) in "pi@raspberrypi:~/solar-sis/example/PIP4084/session.json ") is right ?
Well after much trial on error I’ve managed to install the WatchmonUDPlistener container on WSL2. While I really appreciate the effort that was put into this software, it would have been nice if the container also had a web server and would allow you to edit the config on the web. But with WSL2 it actually made it very easy to find and edit the configuration file, if you know where to look.
Since the Watchmon toolkit is a windows application only, and I already had a PC dedicated to my battery project, it made sense to run this container on the same machine.
if there’s any interest, I can do a quick write up or video that walks you through it.
I have been trying for the last few days to get the WatchMonUdp Listener running on my HA core. Im running HA on a PI3b. So far I have :
1) Installed Portainer as a add on in HA and set up the batrium volume and container.
2) Ive tried both the latest version and the amd64 version.
3) Installed the Terminal and SSH addon so I can SSH into the Pi can and change the config file but I just cant find the config file.
So according to portainer my mount path is /mnt/data/docker/volumes/batrium/_data. If I ssh in and try and find it it appears it doesnt exist.
/ $ cd mnt
mnt $ cd /data
data $ cd /docker
-bash: cd: /docker: No such file or directory
Any idea what I need to do to access the config file. Although if I look at the logs Ive got this.
I’m not great with a Linux command line but once you cd to /data you may have to do sudo cd /docker. But I can tell you that you should use ”latest” tag rather than the “amd64” tag since the Pi has an ARM CPU. And, from my experience, this container needs to connect to influxdb even if it’s been disabled in the config.
I might be asking a bit much of the software here but I have recently got a second PCM60x and I was wondering if it's possible to run two instances of solar-sis to grab the data from both charge controllers? Do you think it's better to add an additional raspberry pi?
