RenierdT 0 Posted September 7, 2020 Share Posted September 7, 2020 (edited) Hi. I have Grawatt SPF5000ES inverter and a pylontech us3000 battery.. I followed the instruction manuals to the letter but I get a error code 20. BMS communication error.. I also found useful info on this forum, followed the instructions (some of the models differs and do not all have the same communication ports, I think) but I still get the same error. I was told that the standard communication cable in the pylontech battery pack is the problem and that they are trying to source the correct cables form China. That might take forever. I am a novice at this solar thing. Has anyone had the same problem or know were I can purchase the correct cable. Thanks Edited September 7, 2020 by RenierdT Quote Link to post Share on other sites
francois 43 Posted September 8, 2020 Share Posted September 8, 2020 (edited) If you have the pin-outs of the correct cable you can have it made up by someone like an IT shop. Edited September 8, 2020 by francois Quote Link to post Share on other sites
Ianvn 0 Posted September 8, 2020 Share Posted September 8, 2020 (edited) I had the same problem with my growatt inverter + dyness battery. I ended up having to wait 2 weeks for a replacement cable. After plugging in the cable everything was working 100%. Like said by francois, you could also try to make a cable using the configurations in the manual. I know we tried and that didn't work. But that can just be something we did wrong. Edited September 8, 2020 by Ianvn Quote Link to post Share on other sites

How are you finding the combo of 5000 es and US3000? Did you manage to get it all working smoothly? I've seen many people having trouble with the 5000tl hvm and us3000 so wondering if your combo is the one to go for. Many thanks Quote Link to post Share on other sites
roadkill 0 Posted March 11 Share Posted March 11 Hi guys, did anyone eventually get this right? I have US3000C and SPF5000ES Couple things i noticed. Pylontech sent me a document with the pin layout and firmware versions required for the different battery and inverter models, but it did not list SPF5000es. as per the manual the configuration is rs485 Cross Pin. However the SPF5000es manual states it is a PIN to PIN. The Cable that comes with the Pylontech, is a standard UTP Cat5 Cable, see documents attached. Quote Link to post Share on other sites
