MPP 3048 support about mpp-solar

[jblance]

What do you mean?
Getting the PC software to work with mpp-solar software?
or
Getting mpp-solar to work with your inverter?

[BarkinSpider]

Getting your software to work on a Pi4 -> RS232 -> MPP3048
I made a wireshark capture of USB1 while running the PC software but didnt see anything obvious
The 3048 is new, looks like they may have changed the protocol.

[jblance]

protocols do seem to vary a lot
do you have mpp-solar on the pi?
what version?

[BarkinSpider]

Hi, Im looking for an install document for your software. I couldn't see one.
Whats the install proceedure?

I have my pi4 ready with Python 3 and USB cable to RS232 connected to my MPP3048.
I can see a few of the Q commands in the wireshark packets. Hope its compatible.

[jblance]

safest is probably a venv install (is documented in the latest readme) ## venv Install ## for when you want to keep the install and dependencies separate from the rest of the environment * create venv ```python3 -m venv ~/venv/mppsolar``` * might need python3-venv installed * activate venv ```source venv/mppsolar/bin/activate``` (needed each time before using) * pip install from git ```pip install -e "git+https://github.com/jblance/mpp-solar.git#egg=mpp-solar"``` (only needed ifthe code is updated) If you get errors, post them and the output of python3 --version

[jblance]

Posting the wireshark pcap will help check what will work and what wont

[jblance]

safest is probably a venv install (is documented in the latest readme)

venv Install

for when you want to keep the install and dependencies separate from the rest of the environment

• create venv python3 -m venv ~/venv/mppsolar
  • note: might need python3-venv installed
• activate venv source venv/mppsolar/bin/activate (needed each time before using)
• pip install from git pip install -e "git+https://github.com/jblance/mpp-solar.git#egg=mpp-solar" (only needed ifthe code is updated)

If you get errors, post them and the output of
python3 --version

[jblance]

Well it claims to supprt PI30 - which is the default protocol
So it should work

[BarkinSpider]

I have a split phase 2 unit system, whats the default name to use for each?

more details on venv https://github.com/jblance/mpp-solar/blob/master/docs/venv.md
shouldnt need to be in bin directory, as long as you have activated and done the pip install

device depends on what is connected to the pi, dmesg and lsusb should help
eg for me:

[jblance]

my output shows a ttyUSB0 and a hidraw0 and not much else - which is because that is all that is connected (2 inverters, one direct USB and one via a SB to serial adapter)

[BarkinSpider]

seems to be happy with /dev/ttyUSB1, but no data so far. Only the output I posted above. Is it because I have two inverters on the same port?

[jblance]

how happy?
post output of lsusb and dmesg|grep USB
also mpp-solar -p /dev/ttyUSB1 -c QPI -I

[BarkinSpider]

How do I query individual inverters (i have 2) I want to know the PV watts of each system.

[BarkinSpider]

I will be mapping all the data with Grafana, Ill send you a screenshot when its done. Ive done all my other solar equipment, see my github page.

[jblance]

2 inverters that are separate boxes, or 2 in the same chassis?

[BarkinSpider]

2 individual MPP3048 (seperate boxes) one for each 120v phase

[jblance]

if they are connected with the 'parallel comms card', try
mpp-solar -p /dev/ttyUSB1 -c QPGS0
mpp-solar -p /dev/ttyUSB1 -c QPGS1

[BarkinSpider]

Thanks for all the help! Is there a cheat sheet of useful commands and values I can set?

[jblance]

That might be an error in the code Just to check can you add a -I (uppercase i) on the end of the command and post the result I'm out at the moment, so can't fix it if its an error, but will do when I get back

Ok, it's getting responses ok, but the decode is failing When I get back I'll add your responses as test cases and fix whatever is the problem. What does watchpower describe the 2 inverters as? Eg '1st phase of 3 phase' etc

Are changes to mppsolar required?

[jblance]

Yes it needs the command definitions expanded to cater for 1st and 2nd of 2 phase as options

ok update now
pip install -e "git+https://github.com/jblance/mpp-solar.git#egg=mpp-solar"
and try
mpp-solar -p test -c QPIRI -I

Good news
Note there are a few output processors including a mqtt one that may help
