  1. Thanks @P1000 I'm happy to report the FTDI converter works. Results of dmesg [160585.535658] usb 1-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [160585.535666] usb 1-1.4: Product: US232R [160585.535672] usb 1-1.4: Manufacturer: FTDI [160585.535679] usb 1-1.4: SerialNumber: FT4WLQTJ [160585.571538] usbcore: registered new interface driver ftdi_sio [160585.571583] usbserial: USB Serial support registered for FTDI USB Serial Device [160585.571745] ftdi_sio 1-1.4:1.0: FTDI USB Serial Device converter detected [160585.571823] usb 1-1.4: Detected FT232RL
  2. I saw the FTDI stuff on RS (because I buy there anyway for business reasons) but I was not sure if it would work. I am almost at the point where I would say cost is a minor/secondary issue simply due to the immense inconvenience/time/money involved when a surge damages the communications on some of your kit. It has taken months of haggling with the bank and quite a large amount of my own money to get my solar system back online. I'll have another look at the FTDI and I will also read up on the ADuM (is that Analog Devices or just a coincidence?). Thanks for taking the time to p
  3. Hi Everyone, Can anyone provide me with suggestions for reputable RS232/USB converters. Preferably I would like recommendations for converters using the PL2303 chipset (because I know it is well supported under both Linux and Windows). I would also like to hear members opinions on isolation or opto-isolation on these converters to ensure that surges and other nasty effects are not sent through to the expensive equipment connected on the RS232 side. As you can probably guess I lost some equipment due to a surge transmitted on the converter to batteries and inverters which fried the comms o
  4. Hi Fredi, I had exactly the same RCT Axpert. Upgrading to the firmware maintained by @Coulomb (and Weber and others) at this location https://forums.aeva.asn.au/viewtopic.php?p=53691#p53691 (actually that link is to the first post which is a must read to give you guidelines on the entire process). It made a huge difference to my system performance.
  5. I'm confused. I thought you were selling two of them. Was about to PM you but then I saw this.
  6. I was dumb enough to make that mistake (just as the "split"/"solar wars" happened). I explained my situation to Manie and he was gracious enough to come to an agreement with me. So kudos to him for that alone. I admit that ICC is not perfect and has had (and still has) it's issues, but usually Manie does try to fix whatever bugs may crop up. From that perspective alone it is worth it. Like other posters above have said, I could probably write this myself, but why bother spending hundreds of hours (that I can rather spend on billable work) when something is available out there. My onl
  7. Hi Forum Members. I'm also in the market for the PylonTech batteries, specifically the US3000B version. I have managed to give my lead-acid batteries a second life thanks to some good advice on the forum but now I think it is time to start planning ahead. Any advice from members would be appreciated especially with respect to combining these batteries with an Axpert parallel setup (I suspect @Chris Hobson may be running something like this). If you are able and willing to supply feel free to PM me or respond here. I'm hoping @SilverNodashi and others are still following th
  8. Thank you. I think I'll give it a go.
  9. Very, very interesting. Thank you @Solaris. I think I'm going to try that. I will also be googling those Devel systems. Weight is not a significant concern for me but I'm a little space constrained. Do you have any experience with these inverters and Lithium batteries?
  10. Thanks @Coulomb. To be honest I've been pondering switching to the 73.00e from my current 72.70c now that my batteries are getting older and especially I have actually seen the kettle cause exactly this kind of trouble where the system switches even though the real DOD is not as poor as the Axpert thinks. I'm a little nervous though, the 72.70c firmware has served my two Axperts (in parallel) really well. Is it worth it?
  11. Thanks @Solaris. I do have the balance wires, which I'm hoping helps a little. I wired them as suggested in the BMV manual. I'm using a BMV702 and it has started to alarm on the voltage difference alarm, but luckily not often. Still, I'm a little worried but not too surprised, especially since my Axperts are not known to be very kind to batteries in general. I'm hoping to get a few more months out of them and then probably switching to the PylonTechs. If only there was an inverter that is reputable, well-designed and that can be paralleled to provide the power that my Axperts give.
  12. Hi All, I was hoping someone would have some advice on the best way to rotate lead acid batteries. I have a lead acid battery bank consisting of 8 x 12VDC (nominal) connected in a 2x4 bank. They have been in service for more than a year now and after measuring individual cells recently I noticed they are not as even as they should be. I am thinking of taking the first and last cells in a bank and making them third and second respectively and making the original third cell the first and the original second cell the last. Any opinions? Am I over-thinking this?
  13. @Coulomb I was wondering if your 73.00e firmware will also help with respect to DOD on older batteries specifically with the "KettleComp". It should prevent unnecessary switching when DOD is not as deep as the Axpert thinks. I think though that the 73.00e is not applicable to these smaller inverters.
  14. My understanding is that centurionsolar and ICC have parted ways. You may instead want to go to the source and contact @Manie or [email protected]
  15. At some point in the past year or so there was some conversation with respect to solar certification. Unfortunately my memory and Googlefu lets me down, and I don't recall if it was here or elsewhere. Nevertheless, there was some talk that in the future any solar installation would require a sign-off from an electrical CoC perspective (by a competent electrician) and a sign-off from a "solar certifier" for the solar PV side. I'm hoping that possibly @The Terrible Triplett or possibly @plonkster may recall. This may only have been relevant for CoCT though.
