Re: Pylontech - Servtec console software
I've tried to decode how they count cycles, without any joy. My pack sometimes goes days without recording a cycle, then clocks up two or three cycles in a week. There must be some sort of algorithm in the BMS firmware that adds up the charge and discharge energy and does some sort of non-linear assessment as to what counts as a full cycle.

Re: Pylontech - Servtec console software
I'm keen on DIY rather than spending £50 for servtec but I'm can't find a good step-by-step description of how to make the cable. Do I need RS232 at all?

+ also RJ45. Then, bin one end of RJ45, and RS232 end of the above cable, and link the cables?Tinbum wrote: ↑Wed Oct 19, 2022 9:39 am edit even cheaper here https://www.ebay.co.uk/itm/275278032717
Re: Pylontech - Servtec console software
NO! The 9 pin RS232 connector contains the electronics that convert from '232 serial to USB and handle all the USB "negotiation" stuff - not a proper technical description - I think it is called enumeration - but you get the idea. Easiest way is to do as Tinbum says, 232 to USB converter lead then get a 232 lead, chop off the end and fit a RJ45. Plug the two together, RJ45 in the Pylons and USB into the laptop.ducabi wrote: ↑Mon Dec 05, 2022 5:42 pm I'm keen on DIY rather than spending £50 for servtec but I'm can't find a good step-by-step description of how to make the cable.

Re: Pylontech - Servtec console software
Do I need a specific version of Batteryview for US3000C? I've connected the cables and checked the wiring couple times, so it looks ok, but it doesn't connect with my version (3.0.28).
Re: Pylontech - Servtec console software
Thats the latest version that I know of and should work OK.

Re: Pylontech - Servtec console software
Is there any specific procedure to connect laptop to battery or just plug-n-play without disconnecting batteries from inverter?
Re: Pylontech - Servtec console software
Just plug and play. Can you see the serial device ok on the computer? Can you select the com port ok in battery view?

Re: Pylontech - Servtec console software
It usually shows com4 but once showed com3. After trying to connect it throws : "after try, 0 times, time out for command".
