Silly Question #240

Closed realSater closed 1 year ago

realSater commented 2 years ago

I am able to connect to the PI30 inverter without any issues, I am able to fetch the data normally, everything is working just fine using mqtt --> telegraf --> influx --> grafana.

I have a non mpp-solar question, if that's fine to ask.

The inverter is showing the output load in watts on the inverter screen (ex: 432w) - this value changes dynamically based on how much load I am having regarding house equipment.

This value does not show in any of the values that mpp-solar is retrieving from the inverter.

List of commands that I am fetching are: QFLAG#QMCHGCR#QMOD#QMUCHGCR#QPIGS#QPIRI

Whether I fetch every command alone or not, I don't see the output load in watts.

the only thing I can relate to, is a parameter coming from the inverter which shows "ac_output_load" and it comes in numbers that doesn't exceed 20.

so after doing some research i figured out that this number is in %. so it shows 3% or 16% load etc.. is there any way that I can convert the percentage into watt?

I tried to google this before i post here, but I have a missing unit value which is the output ampere which is also missing from the data that mpp-solar is fetching, but it shows fine on the inverter screen.

I really appreciate anyone's help on this.

Have you tried QPGS0?

Brand: Crown Micro Model: Durant Model Number: DT-2KW-M

2000W inverter

Unfortunately I cannot seem to find the exact model name on the internet 😂, there are other models with lower Watt. - makes me think it is discontinued...

It is made in China 🇨🇳

But on mpp-solar when i use QPI it shows:

protocol_id PI30

Ok. That's not a command I've seen before. But it looks like "valid charge amounts" or similar

This means there are unknown commands are implemented

I have knowledge in what I am doing, would you like me to bruteforce the commands?

if so can you give me the general letters that usually all manufacturers set in their inverters?

like: letter Q letter S letter V letter P letter 1

etc...

edit: fixed grammatical typo

jblance commented 2 years ago

Does Q3 or Q4 etc give any response?

unfortunately it doesn't, i barely ran it using watchpower on a windows machine

jblance commented 2 years ago

If you do -c without a command it will show all the available commands for pi30

Generally commands start with Q for queries

If you do -c without a command it will show all the available commands for pi30 Generally commands start with Q for queries

great! do you know if there is a maximum length for the commands? say a maximum of 5 letters?

I am about to write a simple script to bruteforce to pass all possible letter combinations to the inverter starting with Qxxxx

but i would like to know the maximum length of xxxx

jblance commented 2 years ago

I've not seen a max length and some are quite long

are you suggesting that the length can be more than 8 characters? including the letter Q?

jblance commented 2 years ago

Some commands include the date and time so are longer than 8 chars in total

Most generic queries are 5 chars or less tho

This thread is going to be long... I hope you don't mind. I will start posting the results once they finish.

so far i noticed that if you issue any command simultaneously it sometimes can generate those weird output data i mentioned up like:

Command: Q2 - No description found
------------------------------------------------------------
Parameter                       Value           Unit
warning                         No definition for command Q2 in protocol b'PI30'
response                        (010 020 030 040 050 060&ê

But if you stop the mpp service and run the commands one by one without any other interference, you will get a correct response whether the command is invalid or not.

So far I have checked the below:

Qn where n is a number from 0-9 Qc where c is a capital letter from A-Z Qcc where both c are capital letters from A-Z Qcn where c is a number from A-Z and n is a number from 0-9 Qnc where n is a number from 0-9 and where c is a number from A-Z Qnn where both n are numbers from 0-9

c stands for character and n stands for number 🤣

I still have: Qccc Qncc Qcnc Qccn Qcccc Qnccc Qcncc Qccnc Qcccn

Will keep you updated

I am closing this thread.

I was calling QFLAG#QMCHGCR#QMOD#QMUCHGCR#QPIGS#QPIRI which is absolutely not necessary and a waste of pull requests from the inverter to mpp-solar.

Everyone who is getting such error or any kind of error like "response too short" is simply due to misconfiguration of the number of times mpp-solar is pulling data from any inverter.

You cannot run mpp-solar simultaneously (you will see errors when running 2 commands at the exact same time or during data pull time)

simply make sure that everything is stopped, there are no cronjobs making mpp-solar run every minute, or any software like monit or such, then trigger your command WITHOUT stacking commands with # or , because they are useless and have no use (at least to my experience, only 1 or 2 should be enough, so don't overload the data pull with 3+ commands)
