Roland on Solar

Dear SiliconKid, I was happy to find your Guide in this forum. I have the very same Problem with my new installation and do not get the BMS to work. Am not sure if this is also applicable to me as your conversation is already 2 years ago. I have - 1 x Growatt SPF 5000 ES with - 2 x Pylontech US 2000 C - 1 x Pylontech cable kit with RJ45 BMS comms cable The inverter switches to fault (cutting off load completely) and shows the same error 20 and an error 04 when put into Li (L02) mode. Already put dipswitch (on Master battery only) to 1000 and pluged into RS485 port, but did not help. Did not do the full program with restarting etc. will try that after work today. I would be very happy if you or other experienced fellows in this forum could help me here since every day the inverter goes in bypass mode when solar power comes in in the morning and fades out in the evening. I guess this has something to do with the not properly working BMS? Thanks in advance! Roland
