NotDave Posted September 18, 2020 Posted September 18, 2020 Hi Everyone. The story is pretty much what it says on the tin: The dreaded "Error 61: Communications Failure between a 5kw Kodak / Axpert King and a stack of Pylontech us3000's The Setup: 1x Kodak branded King 5kw inverter, running firmware 71.90 4x Pylontech US3000 batteries. No solar panels (yet) Everything is new and got delivered from the supplier about a week ago. What I have tried: I have tried to set up everything as was specified in the manual and as I have gathered from the various sources online (mostly on here) The inverter came delivered with an RJ45 cable to connect between the Inverter and the batteries and I verified that the pin-outs matched what I have seen mentioned on the forum a couple of times. I have checked the cable to make sure there was no breaks or twists in it. I even made up my own using some RJ45 connectors and UTP cable in case the connectors was a little dodgy. The cable was plugged into the RS485 port on the master battery (checked and rechecked). I made sure the dip switches were using the sequence: 1-0-0-0 on the master and 0-0-0-0 on the slave batteries. On the inverter the cable was plugged into the Battery Monitor port, and I changed the inverter settings OPTION 5 to PYL. Sadly, no dice. What I think the problem might be: A setting somewhere might not be applied - I power-cycle the batteries and the inverter every time after changing the settings to ensure that if a setting is applied to the inverter when it gets switched on, the change is persisted. I also verify that it changed on Watchpower (Via Bluetooth), but I get the feeling that this is in all likelihood not the problem. Some coms electronics got fried. The pylontechs came with a data cable which I briefly attempted to use (It has RJ45 connectors on it!). In my attempts to get it working, I had it plugged into the CAN bus on the batteries. I am not sure about the voltages on the data lines, and all likelihood this is probably not the problem either as most designs probably has some built-in protection (one would hope) The firmware is out of date- Currently the inverter is running 71.90 but I have seen it mention on the forum that the 71.93 firmware is available. I haven't looked into upgrading it yet, but this seems like the only real option available to me at this point, as I am drawing a blank on any potential hardware related issues. An intermittent solution If all else fails, I'll probably have to configure the inverter with Option 5: USR batteries. From what I understand, the only benefit of the coms cable is that the BMS takes over responsibility of monitoring the batteries rather than the inverter attempting to do it via its own sensors and a bit of guessing. If I go this route, what are the currently recommended settings for these batteries to not void warranties, observe safety margins and maximize the battery lifespan? Apologies for the long-winded explanation, or if I missed something blindingly obvious in the manual, and thank you in advance for any advice and suggestions I should try. -NotDave Quote
Bloubul7 Posted September 18, 2020 Posted September 18, 2020 Hi, The key problem is that the cable delivered with the unit doesn't work. You will have to create your own cable in order for the communication to work. I will look for the pinouts now Quote
Panther Posted September 18, 2020 Posted September 18, 2020 Fault 61!!!! The only way to solve this is in Setting #5 must be USE. Then settings 12;1326;27 and 29 must also be set. Setting 12 48V Setting 13 51V Setting 26 53.2V Setting 27 54V Setting 29 48V Hope this helps! Quote

Somehow, this seems like a failure of the market. Surely a manufacturer should be ashamed of such a thing happening, sending free new cables to all that need it. Instead, they keep shipping the same wrong cable, and somehow don't seem to suffer much of a sales penalty as a result. zsde 1 Quote
NotDave Posted September 18, 2020 Author Posted September 18, 2020 Okay, so I have made 3 different cables now. Sadly none of them seem to work. The cable that was supplied: 3 - 8, 5 - 7, 7 - 5, 8 - 3 Custom cable 1: 1 - 3, 2 - 5, 3 - 1, 5 - 2 Custom cable 2: 1 - 4, 2 - 5, 4 - 1, 5 - 2 I see Coulomb has done some work with firmware updates... Is there a specific version you can recommend? Thanks for the settings, Panther. Quote

Do you know if the above cable pin-out also work between Axpert King <--> Hubble Lithium or what must the pin-out be on the Hubble battery side? I saw that with firmware 71.92 and 02.49 on the King the Hubble's RS485A can be connected to the King with setting 5 set as LIB. I presume it's better to let the battery communicate with the inverter through RS485 rather than having no comms cable and using the manual settings 5, 12, 13, 26, 27, 29? Can you also confirm that all 4 dip switches on the Hubble must stay on 0-0-0-0 for standalone (single battery) use? Quote

No patched version for the King yet - @Coulomb somewhere said hopefully by year end. I can confirm this connection works with Pylontech US3000C batteries and an EA Sun ISOLAR SMV III 5K inverter. My Pylontech cable pack came with a black cable part WIOSCAN30RJ1 (totally wrong connections) which I cut the inverter plug off of and replaced the plug with only pins 3 and 5 connected as per above (in my case the two brown wires). The 'master' battery has dip switch 1 set to 1 (on), the other batteries are all default 0. Inverter and batteries are now communicating. Quote
Hannes Visagie Posted June 5, 2021 Posted June 5, 2021 The comms cable supplied with the Kodak inverter for Pylontech batteries is marked Pylontech at the one end. If you plug that end into the Kodak, you get error 61. I did it. I then swapped it around and plugged the marked end into Pylontech. And the system works 100% Ben Harper 1 Quote
Dirkie Posted September 20, 2021 Posted September 20, 2021 Should this cable work with inverters in parallel I have them in parallel but the inverters with out the cable stil show error 61 the one with the cable plugged into it is fine Quote
Coulomb Posted September 21, 2021 Posted September 21, 2021 11 hours ago, Dirkie said: Should this cable work with inverters in parallel I believe that it should. Reading the firmware, I see that the paralleled inverters share the BMS data amongst themselves, for example. I think some earlier King firmwares (both DSP and removable display) had problems with this though. So updating to the latest firmware (71.97 and 02.66 as I post) might help. Quote
Dirkie Posted September 23, 2021 Posted September 23, 2021 I tried it on two Axpert max inverters in parallel with the freedom won 10/8 batterye and freedom won canbus to rs485 converter. The master inverter works fine but the slave inverter give me the error 61 so I phoned the thech support at freedom one and they advised me to put the slave inverter setting #05 use and input everything manually and the master inverter setting #05 should still stay on LIB. So then that made a new problem the master inverter give me a massage 60 witch in the freedom won manuel it say I should ignore because it wil go away when the battery levels go up but the freedom won converter drops the charging amps of the master inverter to 10amps and cause the battery to be not fully charge during the whole day and it also puts the inverter into bypass mode. So then I went back to the client and put both Inverters setting #05 use and set everything manually know its running well again and the client is happy again Quote
Lucy Posted April 11, 2022 Posted April 11, 2022 I am having the same problem. Error 61 with the axpert vm111 model connected to 2 Pylontech batteries. Should I follow Panthers advice or are there other solutions? Just moved off grid with 2 small children, 1 is only 9 months so in desperate need to get this issue sorted asap. Many thanks Quote

Just leaving this response here for posterity... it was not at all obvious to me that the cable is directional. Quote
Coulomb Posted April 26, 2022 Posted April 26, 2022 23 hours ago, Ben Harper said: it was not at all obvious to me that the cable is directional. Indeed, it's usually wired in such a way as to be non-directional. Or clearly marked. Perhaps now that most models have CAN bus signals on there, there are fewer totally unused pins, so a non-directional cable may cause problems where it didn't used to. Quote
TheSteffen Posted July 21, 2022 Posted July 21, 2022 Hi, i have no Idea anymore. Had aSP24 Primo MKS IV 5.6Kw 48 Volt 5600-48 connected corretly with a Pylon Cable to my Pylon Stack. Everything worked fine. Now i bought a Axpert MAX II 10k-48 ... the Manual was even the same incl. Pin Settings on BMS Port, so it was a plug and play xchange. BUT i only get E61 Error... rebootet everything hundert Times checked all settings again. Made anoter Cable as shown here in the Post 3 - 8 / 5 -7 no success.. only E61 after a few Minutes... no Ideas anymore Quote

I'm tried making all the cables stated above with no luck. Still error 61. Thinking of leaving it on USE but the battery percentage is always wrong. Don't know what to anymore.

TheSteffen Posted July 27, 2022 Posted July 27, 2022 I´ll get another Firmware for Axpert MAX II 10k-48 from my supplier and will let you know if it works. Btw. solarpower24.it has a fantastic Service ! Quote

Btw. solarpower24.it has a fantastic Service ! I beg to differ. Have 6 of those inverters, they do not behave properly in many situations like switching to grid for no reason. SolarPower24 has refused to provideany new firmware or adequate assistance up to date. Quote
TheSteffen Posted August 8, 2022 Posted August 8, 2022 (edited) Hi, i got a MCU Firmware on the same Day, a manual and a very good description how to cutomize the Original Cable in case the update Fails. The MCU is now updated from U2:2212 to U2:2215 and the E61 Error is history. Over all a perfect Service for me from SP24 ! The Firmware can not be Posted here, cause there is a risk that you have a different BMS inside another Axpert MAX II 10k-48. This worldwide chip issue is a mess ! Devices getting different Chips inside... and sometimes incompatible, had also problems with my Pylontech batteries cause of a "newer" (other) BMS they are using now for the current batteries.

yelon Posted October 7, 2022 Posted October 7, 2022 I'm also getting Error 61, running: PowMr POW-VM5K-III (another clone 48V/230V 5kW) custom Lithium (Lev40 / 48V 10kWh) batterypack that has it's own BMS. Question: would you recommend putting it on USE in #05? And then setup all other settings #12 48V, #13 51V, #26 53.2V, #27 54V, #29 48V ? Quote
swenk Posted October 29, 2022 Posted October 29, 2022 Hi all. So I have just added 2of pylontech us5000 to my stack of 3 us2000, connected to a parallel pair of axpert king 5k As per the instructions I have made the newest battery the master and linked the us2000 from it I'm getting error 61 when connecting the bms cable to the new battery. I originally made my own cable and I've just made a new one 3-8 5-7 to confirm. The old batteries were happily working for several years and still work when I revert to just them. Any suggestions? Many thanks Quote
johanvdm Posted November 1, 2022 Posted November 1, 2022 Ok. So I have been running my Synapse 7.2 with Pylontech UP5000 for almost a year now, after also had to make custom rs485 cable. Installed PVs last week and played with some charging priority settings. After doing a full on inverter "reboot" this morning, the inverter displayed the dreadful 61 error. As solution, I changed the baud rate dipswitch on the pylontech to "9600 CAN resistance: connected". On my UP5000, it was dip1=on, with dip2 to dip4 all set to off. It now still seems to be working as expected; Still no idea why it went into limbo. Anyway, hope this helps. Johan Quote
ELEGEX96 Posted December 1, 2022 Posted December 1, 2022 Hi Guys i also have the same error 61 with a 5kwh Greenrich Li-ion Battery and i did plug in a 3,5,7,8 coms cable with the pylon sticker on the battery side and still no luck Any different pin config for the greenrich battery instead of Pylontech ?
