MPP 3048 support #43

Closed BarkinSpider closed 3 years ago

BarkinSpider commented 3 years ago

The PC software works ok, whats involved in getting it working with your software?

jblance commented 3 years ago

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

BarkinSpider commented 3 years ago

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 commented 3 years ago

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

BarkinSpider commented 3 years ago

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 commented 3 years ago

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

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

jblance commented 3 years ago

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

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

BarkinSpider commented 3 years ago

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 commented 3 years ago

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 commented 3 years ago

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 commented 3 years ago

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

so that worked output was PI30 now you probably want some status info, so try mpp-solar -p /dev/ttyUSB1 -c QPIGS

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

BarkinSpider commented 3 years ago

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 commented 3 years ago

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

BarkinSpider commented 3 years ago

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

jblance commented 3 years ago

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 commented 3 years ago

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

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
