Adding commands for LV5048. #11

Closed DMIINC closed 4 years ago

DMIINC commented 4 years ago

LV5048 5KW protocol-20190222 for customer.pdf Hello,

Thank you for your help last week. I was in touch with MPP Solar and they provided communication protocol for LV5048. See attached. Is there way to integrate some of these commands with what you have written so far?

jblance commented 4 years ago

Hi

Yep - if you want to do it just for you - the approach is too add/change the json files in mpp-solar/commands folder (if you do it in the download copy you'll need to reinstall afterward)

For me to do it more generically would take a bit longer as I'd need to add a way to filter commands based on what device you have (though that is probably a good idea for the future)

DMIINC commented 4 years ago

Which file? Is it lot of typing. I have a daughter at the house with nothing to do due to virus. Is it mostly copy paste type of adding commands?

Thanks,

jblance commented 4 years ago

Depends what you want to change... While the mpp-solar can do a summary for you with -s etc. You can also just use the raw commands like -c QPIGS, some of these are the same (e.g. QPIGS), some have changed a little (like QPGSn) and some are new (e.g. QPIGS2) e.g. to update QPGSn you'd edit the mppsolar/commands/qpgs.json (from the downloaded content) to create support for a new command like QPIGS2 copy mppsolar/commands/qpigs.json to mppsolar/commands/qpig2.json and update the content

Then re-install the package with sudo python ./setup.py install

Hope this helps - if not let me know your priorities and I'll try to get time to look at implementing something

DMIINC commented 4 years ago

I really do I appreciate your help. But before we put a lot of work on this, what would be the easiest way to see if these commands can communicate with all 6 inverters. 2 per chassis for 3 chassis. All I can do now is one half of one chassis.

jblance commented 4 years ago

So what command is working now? If you are using -s, try -c QPIGS then -c QPGS0, and -c QPGS1, and -c QPGS2 and let me see what you get

jblance commented 4 years ago

what about sudo mpp-solar -c QPGS1 -R ?

I take it that you are using a USB to serial converter?

DMIINC commented 4 years ago

Same thing for additional numbers

DMIINC commented 4 years ago

Yes usb to serial

jblance commented 4 years ago

So, sudo mpp-solar -c QPIGS -R works? what about sudo mpp-solar -c QMOD and sudo mpp-solar -c QDI ?

(coz QPGS0 should work accord to the doc you sent

DMIINC commented 4 years ago

Unless all of them need to be connected via usb or serial to raspberry pi

jblance commented 4 years ago

thats not what the doc says (i.e. it implies you can get details from any using QPGSn) I've added a QP2GSn command, can you install the latest from git and try mpp-solar -c QP2GS0 -M LV5048 and maybe mpp-solar -c QP2GS0 -M LV5048 -D if it doesnt work The new -M command is to limit commands to inverters that support them

Weird - your inverter doesn't seem to respond to the new commands in the documentation, or the documentation is incorrrect? Maybe you have a 2 digit ID or the ID isnt 0-3?? Did it come with software?

DMIINC commented 4 years ago

Yes. Windows side. It is called watch power. https://usa-mpp-solar.com/manuals/Software/WatchPowerV1.13SP3(latest)/ and you can find Linux stuff on that link.

DMIINC commented 4 years ago

I know just weird. I have been pulling my hair out for last 4 weeks. Just can't figure it out.

jblance commented 4 years ago

Can you check the inverters to see what IDs are set Page39 of the user manual has some details https://usa-mpp-solar.com/manuals/LV5048%20split%20phase%20manual-20191024.pdf

DMIINC commented 4 years ago

They are set as they requested it. System is performing flawlessly.

jblance commented 4 years ago

So the dip switches have the IDs set to 0 and 1?

DMIINC commented 4 years ago

If you look at the diagram all three are set as they want them to be.

Watch power app does see all three.

jblance commented 4 years ago

Nice setup I was meaning the ID number - was wondering if they were set to something other than 0,1,2 - the manual says it could be 0-7 and as long as they are all different everything will work image image

DMIINC commented 4 years ago

Yes they are different

1 off off off

2 on off off and

3 off on off

Does the command QPIGS2 work? i.e. mpp-solar -c QPIGS2 -M LV5048 -I

Interesting - so the only ones that dont seem to work are the parallel commands can you run mpp-solar -c QPIRI -M LV5048 for me please Also, what is the box below the 3 inverters?

Box houses DC breakers for each inverter and generic battery monitor.

OK, so fixed the above error - but I just can't figure out why any command with the parallel ID fails to work - it looks like the command isn't recognized but it is the command as per the documentation.

DMIINC commented 4 years ago

Thanks . I will reinstall in the morning and try again. I really appreciate your help.

QPIGS Inverter general status parameters inquiry for Line 1 of one inverter. It works. QPIGS2 Inverter general status parameters inquiry for Line 2 of one inverter. It works.

With these commands above I see all of the information from one inverter. Since L1 and L2 are 180 deg out that gives 240 volts across them. Full phase. L1 to N = 120 Volts L2 to N = 120 Volts for split phase.

For this to work, I think each inverter will need it's own connection to Raspberry Pi. USB to Serial. Unless you can add lines for USB connection. I do not think that we know the code to pick up all of the information that is floating around through parallel cables between inverters.

And in that case QPGSn and QP2GSn will work. I will see if MicroCenter has any USB to serial cabels today.

DMIINC commented 4 years ago

Bought 2 more USB to serial connectors. Looking better. Shows no errors but no information comes back for QP2GSn QPGSn

Great that you have a solution. Just strange that the commands dont work as per the docs. My parallel 4048s work with QPGS0 and 1 showing the data from the 2 inverters while only connected to one of them.

DMIINC commented 4 years ago

Well. Now when I type pi@raspberrypi:~ $ sudo mpp-solar -c QP2GS0 -M LV5048 it returns as this

pi@raspberrypi:~ $ sudo mpp-solar -c QP2GS0 -M LV5048 pi@raspberrypi:~ $

It does not give error or anything else.

jblance commented 4 years ago

Sorry, yes i was cleaning up some of the log messages I have added a bit more information to the response if the command fails now - e.g. mpp-solar -c QPIRI -d TEST -M LV5048

Will test it out. Thank you.

cowpen commented 4 years ago

Very glad to see you guys working together on a solution to this. I have an LV5048 and have been struggling for a couple of months trying to get a data logged in a useful format with "solar-sis" for the 4048. Your efforts are very much appreciated!

DMIINC commented 4 years ago

Ok. I see what you mean. Well. It is another wall barrier. I need to put my hard thinking hat on.

jblance commented 4 years ago

ok, so the java code shows the command is QPGS0 - also it has some indication that it tries multiple times... e.g. the below tries 3 times from P41ComUSBProcessor.java

for (try_i = 0, try_i = 0; try_i < 3; ++try_i) {
                ret = handler.excuteCommand("QPGS0", true);
                if (!ret.equals("(NAK")) {
                    break;
                }
            }

Maybe try bruting it? Can you try the below: for x in 1 2 3 4 5; do echo $x; sudo mpp-solar -c QP2GS0 -M LV5048; done

DMIINC commented 4 years ago

With my thinking hat on........ can it be done via USB connection? Three USB cables = 3 devices There for mpp-solar -c QPIGS or QPIGS2 -d /dev/hidraw0 or 1 or 2
