Voltronic Infinisolar 10k hybrid support

[mstuetz]

Hi!
After running 123solar and mN for a couple of years for my Infinisolar 3k (and other) inverters, I started implementing it for Infinisolar 10k hybrid / MPP Solar 10k hybrid and compatible inverters.
The software is in an very early stage, but almost everything (logging, startup, checks, alarms, battery) is implemented already and works for one installation so far.
Any testers are very welcome. I will try to help as good as I can and I'm open for any improvements.
I put the 1st quick'n'dirty script here: https://github.com/riogrande75/infinipoll10k/

Thanks, tell me if i could include your protocol files.

[mstuetz]

I sent you the protocol files.
If you need anything additionally to add them to the next version, pls. let me know.

[jeanmarc]

Thanks, it'll be included in next release

Hi,
I would like to try the protocol with an MPP solar. How should I configure the inverter on 123solar? Which cable should I use? A normal usb-serial or a direct usb cable?

Thank you

[mstuetz]

Pls. read github readme.
My script needs a serial to ethernet converter (e.g.USR-TCP-302), off course you could simply adapt it for the use of a usb-serial converter.

I run 123solar 1.8.2 now since a few days and a lot of mem get's eaten up (>300MB after one day).
In fact mem consumption increses 24-30 bytes every 3 secs.
Off course I suspect my own scripts in procotols/ folder that I use for reading values.
So one basic question: Do this scripts get included or executed by 123solar? Any hint how I could find the memory leak?

[jeanmarc]

Well, try to see with "htop", then F6 sort by %MEM to see what process eat your memory.
Your /tmp/ is on a tmpfs ? Check what files grow there..

The protocol file is continuously open/close, check if you have fclose everywhere.

In fact it's 123solar itself, as far as I understand.
ps aux outputs this:

Code: Select all

www-data 26902  7.7  6.7 109636 64176 ?        S    12:45   8:07 php ../scripts/123solar.php

top -p 26902 shows this

Code: Select all

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND

VIRTual and REServed memory get increased every few seconds.

No big filesystem changes, as far a I see.

I suppose it's about your protocol file. My RES is stable as rock
Try to make an infinity loop while(true) in it, then test with php infini10k.php &
