@Mauritius B Thank you for your response. I agree. I run 2 x US3000C Pylontech Batteries and have changed all the settings to what was recommended by you guys. I have changed the cable from the batteries to the inverter and still getting the error 4. What worries me even more is that I am not getting the utility savings that I expected with my current configuration. 1 x 5KVA RCT - AXVM3-5K48V inverter connected to 2 x US3000C Pylontech Batteries and 8 x Jinko/Tongwei 555W Mono Solar Panels As a matter of fact, before installation of this configuration, I was using on average 24KW of utility power per day. Now my average is 17KW per day. This does not make any sense at all.

@Scorp007 The 04 is indeed a warning with ! mark in a tri angle.

Hi All, Thank you for your help and advice. I have done what you have suggested, and it seems that the system is now running much better. I have still not resolved the error 4 issue when I change setting 5 to Pyl. I am not getting the 61 error, which means that the system can see the batteries, but the error 4 remains. It seems that the system is not getting the correct data. Is it possible that it could be the firmware that is not up to date?

Just to confirm. Here is my current settings. Are they correct? how can I optimize my system? 1 SUB 2 30A 3 APL 4 5 USE 6 LED 7 EFD 8 9 50 10 230V 11 20A 12 48V 13 48V 14 15 16 CSO 17 18 BOF 19 ESP 20 LON 21 22 AON 23 BYD 24 25 FEN 26 52.5 27 52.0 28 29 46 30 EDS 31 53.2 32 33 60 34 120 35 30D 36 ADS 37 NFE 93 NFE 94 10 95 38 96 3 97 26 98 4 99 24

Hi Mauritius B, Thank you. I am actually now running as per your point 1 and as per what Chris has said. As far as your point 2 is concerned, you are correct. I did initially have the error 61, but after rebooting batteries and inverter this disappeared and the error 4 came up. I then obtained a new cable from the supplier, and I still have the error 4. On the inverter it shows the error 4 and that the batteries are low. However, on the batteries itself it shows that they are 100% charged. It also shows on the inverter that the batteries are charging, but the error 4 remains and it shows now progress in terms of the batteries being charged. I have read all the manuals, but can't find any reference to this particular problem.

I have read all of the above and still do not understand the error code 4. My conclusion from the above is that Pylontech batteries are not compatable with by inverter or the current firmware.

Hi Spys! I have actually now replaced the cable, but still getting the code 4 error.

Hi Spys! I wil check the cable.

Hi Maritius B, I have done that, but then got a code 4 (low Battery error), although the batteries showed full when the setting was on USE. I cleared the error 4 code by changing back setting 5 to USE and then batteries are full again. I have no idea why?

Hi all, I am new on the forum and also very ignorant regarding the technical issues on my current inverter installation and settings and really need help. It is sad to advise that the people who did the installation and suppliers are unable to advise on the correct settings. I have manged to change some settings after reading the manual, but I have a feeling that there are settings which are not correct. My installation consists of the following: 1 x 5KVA RCT - AXVM3-5K48V inverter connected to 2 x US3000C Pylontech Batteries and 8 x Jinko/Tongwei 555W Mono Solar Panels and; 1 x 3KVA RCT - AXPERT 3K Inverter connected to 1 x UP2500 Pylontech Lithium Battery. Not connect to any Solar panels and only provides backup for lights. No issue with this. My objectives are: 1) Optimize the Solar and Battery Capacity. 2) Reduce the usage of Utility power to save cost. 3) Ensure sufficient Battery capacity during Loadshedding (Power Outages). I am running a small household for only two people with my Geyser charging from a separate Solar panel, but is also connected to utility power when needed (Geyserwise). Please note that my Stove are not connected to the inverter. It would seem that if I run on SBU mode and solar is not working in late afternoon, the batteries take over, but drops from 54V to 50V very quickly. Then soon after that the low battery alarm is sounded. 1 SBU 2 30A 3 APL 4 5 USE 6 LED 7 EFD 8 9 50 10 230V 11 20A 12 44V 13 51V 14 15 16 CSO 17 18 BOF 19 ESP 20 LON 21 22 AON 23 BYD 24 25 FEN 26 56.4V 27 54V 28 29 42 30 EDS 31 53.2 32 33 60 34 120 35 30D 36 ADS 37 NFE 93 NFE 94 10 95 47 96 3 97 21 98 4 99 24
