  1. Has anybody used this combinations? I cannot get the Inverter and battery to work - communicate BMS and have to run the inverter on the User settings and not Pylon?. I'm not sure if the RCT uses the RS485 or Can protocol ? as the standard RS485 pins 8 & 7 on battery and 3 & 5 on inverter don't seem to work? Any help will be appreciated
  2. Does anybody have the Weco Battery protocols for reading on the RS232 port? I have a couple of installations now with Weco batteries and RCT inverters. I can use their battery monitor software but would like to read my own readings if possible. I tried contacting Weco directly but they don't seem to be interested to help
  3. Hi Not sure if this still relevant... if you interested... I just connected a 8kw RCT inverter and 2 Weco 5k3 batteries and it is working fine...
  4. I don't know if this has been posted here before but I noticed that once I connected and registered my Axpert MAX wifi and I can access it on watch power, it is also registered and data is captured on a website http://shinemonitor.com/ You can login with the same username and login. There is a lot of your system/inverter data there and all your historical inverter/solar data. Not everything on the site works but I haven't configured all the inputs. Also, before you login there is a link to a Andriod App you can download on the top of the page. The app looks like it has Push messaging available but I haven't tested it yet. Hope this helps somebody...
  5. Hi @ThatGuy ICC is great but a few reasons... ICC will read the MAX data but do not have all data on the trends for two MPPT's... both on the Main dashboard but only 1 in the PV trend graphs ie Watts/Volts/Amps per MPPT... I prefer to have my own visual layout with the dashboards that gives me only the data I want to look at the moment... ICC don't keep yesterdays data graphs if it reboots, etc. and sometimes I like to look back at graphs from last week... I can look at the data on my tablet/phone without having to use econcms or vnc and even manipulate it in grafana and then also I started playing with the mqqt plugin which will allow me to write my own rules for switching the fridges geyser and other devices on and off when PV power varies. The features in Grafana is numerous ie alerts, etc I just feel I have more control over the installation if I do my own software.
  6. I'm got a Axpert MAX with 3 Pylon 3.3k batteries and use ICC to monitor and that works ok. BUT I am now trying to create my own simplified panel with Node Red and Grafana. I managed to setup the Raspberry Pi with Node Red, Influx DB and Grafana and created the Dashboard. This works quite well now and I can monitor the inverter basics on the RPi via VNC or on my local network with the RPi - IP on port 3000. I used and adapted the Node Red code (thanks to Tejota) to pull data from the MAX RS232 port via a USB - Serial adaptor and the inverter supplied RS232 cable. My next challenge is to read the Pylon batteries via the console port as I want start using some of the battery stats and switch some Sonoff switches . I have the cable (USB-Serial to RJ45 - Pylon 3000C console port) that works with ICC and that works fine. Can anybody help me to setup the Serial Port to read the Pylon Data into Node Red. I did find the Pylon info where you setup a terminal at 2400 baud rate and send a 7E 32 30 30 31 34 36 38 32 43 30 30 34 38 35 32 30 46 43 43 33 0D ... then switch to 115200 baud and do the rest... this is above my capability. I don't know how to dynamically switch baud rates, etc.... I found that when I start to fiddle with the 'serial in' node or create a second 'serial in' node in Node Red it screws up all my invertor data. Any help will be appreciated. Tj
  7. Hi Coulomb, I don't have any way to measure it but the utility meter crepes up slowly all the time ie. from 61 777.7 to 61 778.6 the same time next day. I did not expect it to consume any utility as the inverter is fulltime in SBU mode and always had enough PV or battery to cover load. I have disconnected the mains switch to stop it as I currently don't need utility backup. May be different in winter time. As for the OTG update not working could be anything. At least got the update done with the serial cable.
  8. Some feedback.... 1. Since the firmware update I can now confirm that I did not get anymore F55 errors. Looks like the firmware resolved that issue. 2. As for the feedback issue... I'm not sure if it is feed back to Utility as I seem to get Utility usage of 0.5 kWh even at night. It starts to look more like some leakage as I do not see any numbers in the ICC monitoring software. I do not need Utility at the moment during the summer months so will switch off my Main Switch and see. Other than that the inverter perform fine and on sunny days my three batteries are fully recharged after 3Hrs and on cloudy days 5 - 6 Hrs @Coulomb - That was after Pressing the 'YES' option on the the MCU. The 'No' disappears after that.
  9. Morning @Coulomb I tried with varies versions of the software (both from the one you mentioned and another I downloaded) to do the OTG cable update by only copying the DSP.HEX file to a USB stick, then plug it into the USB port. You then select the USB function with the top left panel button and Upgrade as per the menu's. The display did power down and show UPG YES and then sat there for 10-12 minutes after which it returned to normal display and when I checked the unit was still on the old version. It tried this with only Battery connected, then Battery and Utility, then only Utility, then Battery, Utility and PV but no difference. Also tried with three different USB sticks. None of the optioned worked. Could be a error in the older versions of the firmware to handle OTG updates? Somehow the only thing that worked in the end is the Inverter update with the software via cable from 45.02 - 90.19 and then the MCU via cable from 12.02 - 12.03. @Schnavel I have got two of the MAX 7.2kW inverters installed. (One at my house and one at my neighbours) The one installation is configured with MPPT1 2 x 5 panel 335w and MPPT 2 x 4 panel 335W (4 strings total 18 panels) The MPPT voltages is 200v and 165v which is well below the inverter maximum's of 500voc and 450 operational. Connected to 3 x 3.3k Pylon batteries (No problems except for some Utility feedback during charging at high current.) I used ICC on this install. The second installation is configured with MPPT1 1 x 7 with panels 335 and MPPT2 with 1 x 7 panels 335. Both with MPPT voltages of 280 V (This is below the spec maximums) Connected to 2 x 3.3k Pylon batteries. This installation kept on 'tripping' with F55 errors (required full reset) when the sun got strong or spiked due to clouds and charge current exceeded 50A. I'm not sure if it was due to the higher PV voltages? I tried ICC on this install when I had the F55 problem but didn't make any difference. I set the max charge current to 50A but the Pylon BMS kept on resetting it back to 70A. The only thing that fixed the F55 fault was the Firmware update. I updated both the inverters with a new serial cable as wtjadens post above (2 other USB to serial cables I had did not work for the upgrade although they work fine for Pylon battery monitoring) connected to the serial port from my laptop and using the respective software update tools for Invertor and MCU. Both inverters is now on Firmware 90.19 and MCU on 45.03. Since update had no more F55 errors on the second installation. Jury still out on the feedback into utility. I will monitor over the next few days and let you know. I am using ICC on a Raspberry PI4 on the one installation and MultiSIBControl control on the second and both sets of software seems to work well although had to make up both cables for the Pylon battery monitoring to the Invertor and ICC. Yani from MultiSib fixed the software to pickup the Dual MPPT's of the MAX. Only issue is you need a PC nearby. I'm using a old laptop. The cooling fans on the units is quite 'loud' when under load so make sure you install somewhere away from living area I have ordered two Sonoff switches which will hopefully arrive tomorrow and I can try them out as well. want to switch of my fridges at night to reduce load on batteries.
  10. I tried the OTG cable but sadly that did not work either. I have now tried OTG cable and 2 different USB - Serial cables and yesterday got the Mecer one suggested by wtjaden and it WORKED first time!. The Serial port on the inverter seems to sensitive to the serial chip in the USB-Serial cable. Inverter now reads 90.19 firmware after 10 min update. I have also noticed that the version 45.02 was feeding back into the Grid causing a 1-2 kWh POSITIVE reading on my meter per day. I will check today if the Firmware update resolved my F55 error and if the unit still feeds back into the grid. Thank you all wtjaden and all others for the input and suggestions!
  11. I do have a OTG cable so will give that a try tomorrow. I have done the Main display upgrade with the serial cable... just the main firmware that is giving me error messages. Thanks for your help.
  12. @Coulomb Thanks for your input ... Only just saw your response Have you done a Firmware upgrade on the USB port on a 5kW model? or is this just something new on the 7.2 kW? I am curious to find somebody that knows how that works?
  13. Thanks @ThatGuy I now have two of these units installed and the other one I have the ICC software installed and and that one seems to run very well. No feedback. No problems. I was trying not to have to buy another set of ICC kit (pricey now) but last resort will do that... Just need to get the firmware upgrade done then hopefully will be OK without ICC. Thanks anyway for trying...
  14. Hi Everybody I installed this software with a Axpert MAX 7.2 and had a problem reading the second PV string. I contacted Yani yesterday and today he send me a updated version of the software. Excellent service for a Free version of software. So once more, many thanks to Yani for the quick response. Your software looks great and works well now. Tj
  15. Hi Guys @ThatGuy Thanks for the response ... The 7.2kW unit is quite different to the 5kW unit in the sense that it can take Voc of 500v and operate between 70-450v so cannot see that as a problem. I have now been searching hi and low on the net and found a few explanations for the f55 error... There is quite a lot said about the invertor and the version number changes here https://www.solarweb.net/forosolar/fotovoltaica-sistemas-aislados-la-red/48226-voltronic-axpert-max-review-profundidad-3.html and Tejota from the solarweb forum explains the F55 it as Bad news about the Max Yesterday morning the F55 came out three times in a couple of minutes The first 2 it recovered by itself, but the third crashed and I had to turn off everything and restart by hand I will observe it for a few days and count , but I didn't like that behavior at all It's a "brake" problem. It will happen to you in battery mode, with Sun and leaving a charge. That is, when most of the solar energy generated by the fields goes to the connected loads. If the load stops demanding, the governor has to brake and skid. If it skids a little, it recovers (F55 without restart) ... And if it skids a lot you go to the gutter (F55 with restart).The only solution I have found for this is not to use the battery mode (SBU) while charging and there is sun. That is, put SUB for the day. And late-night SBU.In SUB the "wheels are wider" and the skidding eats up all the connected network. In fact, it is not uncommon to see hundreds of watts discharged to the network when you are regulating at maximum.When I saw a daily clock on the display to configure SUB, SBU and UTI I saw it clearly, very clearly. It must be difficult to correct those skids." =================== I tried to run in SUB mode during the day but still had the problem AND then later on in the thread he says "At the moment it seems that the 90.xx handles F55 errors better. This F55 error occurs when you have a lot of generation, low consumption in loads and SBU mode (battery mode). If you make the regulator enter and exit when entering and leaving loads it is possible that some F55 will jump. As far as I know, in the new updates with the 90.xx they have been able to fix this although I have doubts that they have corrected it completely.The F55s come in two forms, a soft one that only cuts the AC OUTPUT for a few seconds while the MAX is reset.the solo and the hard one where you have to manually reset it by turning it off and on as it remains in permanent failure mode.That is what is partially known but that jump from 45.xx to 90.xx is that they have completely redone the firmware for some unknown reason. The normal thing is that they would have continued with the 45.xx polishing in successive xx. ============================== So it looks like the 90.19 could possibly be the answer. wtjaden in powerforum thread managed to update his MAX to 90.19. in December last year. He got software from https://www.ostrovni-elektrarny.cz/support/Axpert/FW/ which was originally 90.11 but now has 90.19. That's where I got the copy of 12.03 and 90.19. I have seen it mentioned in other threads that one can possibly do the upgrade via a OTG cable and flash drive on the USB port?? but I am a bit wary as I have nowhere seen it done by anybody. If anybody know how that works I would be grateful.. Thanks for your assistance... Tj
  16. Hi I wonder if anybody had this problem. I installed a Axpert MAX 7.7 kw (Brand Synapse 7.2kW from Rubicon) with 2 strings of 7 x 335 Watt panels and two 3.3k Poly batteries. The unit runs fine most of the time but in the morning when the batteries start to charge the unit will kick out intermittently when the battery charge current goes high and give a F55 error. Some times it restarts but once or twice I have to restart it. I have read on the Spanish forum that a fix would be to update the Firmware. Current firmware was 12.02 on Panel and 45.02 for Invertor. I downloaded the Firmware 12.03 and 90.19 from a link on another post here and managed to update the Panel to 12.03 BUT I cannot get the 45.02 updated to 90.19. I start the update process the update opens and I reply 'Yes' to update confirmation then the invertor screen click and it displays... ====== Upg Yes ====== and 5 second later the PC complains that it cannot open the Com port. In the update status box it then shows 'Com port 4 open' but nothing happens any further. I tried varies com ports but always the same. I feel I need to maybe press a button on the invertor to allow the process to continue? Tried varies but no avail. Anybody done this before on a MAX? Any help will be appreciated. Tj
