  1. Any feedback? Your 7 weeks are up, and I am following with interest.
  2. Louis, I think it might still be true. But compare it to battery costs when no grid is available (and enough wind is), and I believe it is a viable option (with solar giving the base load). My neighbor has been running a wind turbine for the last 16 years, with minimal maintenance cost, supplying him with all his power needs. He still use lead acid's and I am not keen for that. I just believe that there is a big part of the word that do not have access to the grid, where this might be viable. Not for 100 turbine manufacturers, but for a few. My neighbor will need to replace his turbine in the next few years, and I can promise you that proper integration with lithium with put that supplier on the top of the list of possibles.
  3. Agree, when can you deliver? 😀
  4. It seems as Jaco's proposal is the only way then. I share the concern for an potential over current (if working in parallel to solar) or temperature event, damaging the Pylons. I understand that wind is limited relative to solar, but given the right circumstances, it does make sense. I have the privilege to have a farm in Namaqualand, right on the escarpment, with fresh winds almost as prevalent as the sun. While we do not have many cloudy days, they do happen. Having no grid, my options is either to increase the battery bank, or get wind (or start the 1946 Lister). In this scenario, one cannot compare wind costs with solar. The correct way is to compare it with battery costs, and then it start to make financial sense. It is amazing that it seems there are no small wind turbine manufacturer that is investing in R&D anymore? Lithium batteries is almost mainstream now, and with that, voltage control on its own does not make sense. I think there an opportunity here for someone like @plonkster to develop a simple interface. Read the instructions from the battery bms and translate that to a "voltage state" that the wind controller understand and obey. Adding the "nice" to this to give information through to GX or ICC will be a bonus.
  5. @SteveFury Can you describe the "works perfectly" (the Bornay wind turbine mppt)? Is it based on voltage settings, or does it allow the battery bms to dictate the charging? Another question, closely relating to this, is does it communicate with Victron via can-bus? I am asking this such that one can get generation stats on VRM.
  6. Hallo, I do not know the other brands, but Victron have the BMV battery monitor, that measure the actual energy passing. Best regards, Herman NS, I just had to answer you, Herman!
  7. Thank you Kobus
  8. Good morning, Any feedback on this testing? Does the charge controller communicate with the pylontech batteries? Or is the control still the simple voltage measure? Best regards, Herman
  9. I can vouch for this, except in my case it took about 10 weeks.
  10. https://pwrcell.generac.com/users/144/dashboard
  11. It seems to have died in 2018
  12. Do we have any indication what these settings should be?
  13. Welcome in the hood, I am across the road in Steynsrust.
  14. Dear All, A colleague of mine has a SMA setup with a Sunnyboy and Sunny Island. The installer that sold him the system is no more. He is in the market to replace his lead acid batteries with lithium, and I volunteered to ask here is you guys can give any good references? Regards, Herman
  15. Hi, Can you give us a ballpark figure for the controller? Plus, the big question, like @jasonvanwyk asked, how well will it integrate with a Victron setup? Best regards, Herman Ps, if the first two gentlemen is not taking it, I will be interested as well.
  16. My 1989 2.5D still works fine, you must have a bad sample!
  17. I heard the other day that this whole Eskom problem was actually created by the Afrikaners: We have a saying "vele hande maak ligte werk". The management at Eskom believed the Afrikaners, as knowledgeable people, and started implementing ........ I tend to think, if we just switch off everything but the lights, it should still hold true?
  18. @plonkster, And do I understand correct that this setup is part of the Approved setup's for City of Cape Town (ie two anti-islanding devices)?
  19. Hallo Grant, Welcome to the forum! Do you understand the risk of buying second hand batteries? Personally, I will consider buying everything solar, but batteries, second hand. Best regards, Herman
  20. Excuse the newbie question, but why, except it being neat, or that regulations require it?
  21. Thank you, I can get new ones on a black friday special for fairly goood prices, but I have not seen any member mentioning them yet.
  22. Sorry about the wrong folder!
  23. Good morning all, Do anyone have any experience with Victron's Gel batteries (BAT412201104)? Thanks in advance, Herman
  24. Thank you. I appreciate your responses.
