New software for Inverter/Pylontech monitoring and control


Recommended Posts

Hi.  According to pylontech manual pin 1 and 8 are the same, Pin 2 and 7 the same.  They recommend using 6 -grd, 7 - RS485A and 8 - RS485B.  Will change connector to see if any change.

I'm using usb to serial convertor that I use with all my softwares for PLC programming and have no hassles.  Some PLC's have issues if convertor not good.  

On the 9 pin plug what must the connection be.

Thanks

Hi @yani Really nice software. One question, is there a way to get it to switch to solar at 07:00 and grid at 16:00? I'm using agm batteries and the switch to grid or battery does not work. I assume the switch only works when you have Pylons connected, or is there a way to do it while having the agm's connected?

Hi, I did make a serial cable for the console port on the Pylontech U3000 that plugs into a USB to RS232 convertor. Images to make the cable are in an earlier post. At first I could not get it to work. Checking on this forum and in the pylontech manual I found on this forum the baud rate of the USB to serial must be set to 1200 in windows. I hope this info helps the next guy trying to connect the Pylontech through the console port. It all works 100%. This is really great software :)

@Xman.

May you kindly share the schematic diagram for the cables please if you don't mind. I am planning to build one for my unit as well .. 

 

Many thanks

This is the diagram I used

I used one of these connectors below. I had a old phone cable with the 4 wires and I crimped a rj45 on the one end so I did not need to solder the connector

Hope this helps

You get a connector like as well this is you want to avoid soldering

Hi Everybody
 

I installed this software with a Axpert MAX 7.2 and had a problem reading the second PV string.
I contacted Yani yesterday and today he send me a updated version of the software.

Excellent service for a Free version of software.

So once more, many thanks to Yani for the quick response.

Your software looks great and works well now.

Hi All,

So, firstly, can MultiSIB control be run from a Pi?  Because I don't want to tie up my laptop monitoring my inverter.

And then secondly, is there a way of linking it to my MCB to turn off, for example, the pool pump when the battery (Pylontech) SOC drops below a certain level, and turn it back on again when it climbs back up again?

Many thanks

Hi all

Tested Multisibcontrol on Windows 10 laptop. Picked up my Mercer MKII's(Parallel setup) but at first could not see my 4 Pylontechs(US3000c).

I made up my RJ45 to Serial(Diagrams attached) , plugged it into console port of master battery and used a regular serial to usb cable to connect it to the USB port on my laptop. After plugging and removing a few times it still didn't work. 

I then opened Device Manager on windows 10 , plugged in the usb/serial cable again and saw a little ! indicating incorrect drivers of the new device. I clicked on properties / update driver / windows recommended search from internet. The CH340 driver was installed(same as arduino drivers I think). Once installed I unplugged the usb/serial and plugged it back in opened Multisibcontrol. After a few seconds it detected all 4 Pylontechs and showed all parameters. I did not have to change Baud rate settings.

I plan on using an old laptop and chrome remote desktop to mirror the desktop onto my computer and work or onto my phone for now.

Has anyone got any examples of the Device Control setup? 

Is it possible to check the Pylontech's SOC% is > 95% at 17h00, if NOT then change Output Source Priority to SUB. Once the SOC% is > 95% then change Output Source Priority to SBU.  

If there is another way to do this please advice me.
