AntonDj Posted July 24, 2021 Share Posted July 24, 2021 I am using a single Dyness B3 with RCT 8kw inverter. Can someone please advise me what is a sensible cut off voltage for this battery. Also need advise on a sensible back to grid voltage. That will sustain battery for as long as possible but still keep me within warranty parameters. Thanking you in advance Quote Link to comment Share on other sites More sharing options...

Thank you .. I am also not getting communication it seems..as when power goes out battery shows full but inverter immediately reports low batt and shuts off. My dip swith is 2 on..rest off. Cable battery side pin 1 goes to pin 5 on inverter and pin 3 on batt goes to pin 3 on inverter. Please assist Edited July 30, 2021 by AntonDj Quote Link to comment Share on other sites More sharing options...

If your problem is that there is still a problem with the communication between the inverter and the battery, I need you to confirm something. Have you completed the basic communication settings between your battery and the inverter? For example: 1.You should use RS-485 communication，and the dip-switch you need set to 0100（the DIP switch must be set when the battery is turned off）. 2.You need to confirm whether the communication cable is used correctly，and i have attached the cable sequence diagram of the correct cable. Please see my description. I believe it matches yours? My dip swith is 2 on..rest off. Cable battery side pin 1 goes to pin 5 on inverter and pin 3 on batt goes to pin 3 on inverter.

AntonDj Posted August 2, 2021 Author Share Posted August 2, 2021 27 minutes ago, Dyness said: I hope you will give me the SN of the battery as soon as possible to check the software version of the battery, because if the software version does not support communication with the inverter, it can only be used in lead-acid mode.In the lead-acid mode, the inverter can charge the battery, but there is no communication, so the voltage and SOC displayed by the inverter are not accurate.

AntonDj Posted August 3, 2021 Author Share Posted August 3, 2021 6 hours ago, Dyness said: According to the factory shipment record I checked, the software version of your battery is not applicable to the inverter. You need to go to our third-party after-sales company Recron in South Africa to update the software program. The software program update is free. Which city are you in? ? I offer you the location closest to you. Hi Can i not do this myself, i have to get an installer to remove the 30kg battery from a 3 meter cabinet and drive 50km to them and then do the same to reinstall which is going to cost a lot of money. I am more than capable of doing the upgrade myself if given the procedure. Please advise.? Quote Link to comment Share on other sites More sharing options...
AntonDj Posted August 4, 2021 Author Share Posted August 4, 2021 (edited) 3 hours ago, Dyness said: The upgrade program requires special tools and it will be very troublesome. If the upgrade fails, it will be more troublesome to resume. Have you contacted Recron? I am pretty sure if i can upgrade a battery if i can program and upgrade firmware on swithes and firewalls. This battery will be no challenge. I have tried to contact them many times. They took 30 days to reply. Then more than a week. I have sent email once again to repairs supervisor Werner Bezuidenhout on 28/07/21 again no response. Good luck reaching them on phone and getting hold of him. Tried many times. Expanding on Dyness and buying instead of Pylontech does not seem viable in South Africa. Especially if this is the level of support. Can the procedure and firmware be made available i will take full responsibility. Edited August 4, 2021 by AntonDj Quote Link to comment Share on other sites More sharing options...
