  1. What is the price for one of the four-bay Pylontech rack/cabinets? If the goods is only available late June 2024, how would you propose dealing with reservation and payment? Or is this just a feeler?
  2. Welcome to The Powerforum, David. I agree that the evaluation of the units are important, also the quality of the repair. I also understand that these things do take time. I don't have a problem with that, and that's exactly why I went for Sunsynk, my choice was based on the perceived strength of the product as well as its logistical support, which I thought was good because there was a policy and process for loan units under warranty in place. Loan units (for inverters under warranty) solve the problem of clients being without their inverter for extended periods while a quality evaluation and repair is being conducted in the workshop. This is especially true for South Africa when we consider the poor service delivery from the national utility. Imagine my surprise when I discovered one year later that this policy and process was discontinued, please see my to Keith earlier in this thread, which links documents that were authored by you @David Drake: In short, I feel cheated by Sunsynk, who promised one thing, but delivered another. It leaves a bitter taste in my mouth, which will last for many years. You have a great product, but its reputation is tarnished by management's decision to renege on the promises which were made 2 -3 years ago.
  3. Congratulations @Marius Halgryn ! Looking forward to the photographs.
  4. I'm not sure on that topic, but quite a few members here are, and they may be along shortly to comment. The only problem with not having a Solarman or Sunsynk dongle is firmware updates, you will need to update if you need support, and with no way to update it, you get no support. Personally, I'd grit my teeth and buy a 5K Solis S6 to replace it with, then flog the Sunsynk in the classifieds when it comes back from RMA.
  5. If it were me, I would firstly be suspicious as to why the first Solarman dongle died. Did it really die, or is it the serial port on the SS that is dead? If you are sure that the Solarman dongle is dead (only way to test would be on another inverter), then it could be the serial port that caused it to go faulty, so you must proceed with caution. You can buy an LED debugger from Aliexpress, but before you waste money, first try and see of you can get about 5V power from the female port on the inverter, this is usually from the Data Terminal Ready (DTR) and Request to Send (RTS) pins. Easiest to use 9pin male DB9 connector, wire it up and plug it in, put a voltmeter across the wires coming from pins 4 and 7. If it's dead, then you know that the UART / port is blown and best to send it in.
  6. Item Wanted: 1x used Pylontech US3000B / US3000C / UP5000 in good condition Packaging Essential: Nope Desired Age: 3 years or under Location: Gauteng Willing to accept a shipped item: No, will collect Ballpark/Budget Amount: Negotiable
  7. These are the biggies, the 100 year cycle ones are the Carrington Events. From my home's perspective, I'm not a radio ham, so I don't care to much about the smaller ones. What I am interested in is what I need to do to protect my home system (and home equipment) from the larger ones, which are imminent.

  9. I stumbled on this Tucker Carlson interview, where he speaks with Dennis Quaid on the risk of Solar Storms. Very interesting. A long watch (45m) but the first 25m is worth it. (00:40) Grid Down, Power Up (25:00) His Favorite Movie (32:18) Dennis Quaid Sings a Song (39:44) Election Worries
  10. For my next install, I will be buying Solis. Apart from being a more advanced unit than Sunsynk, they at least have logistical support in the form of swop-out units for repairs under warranty. Plus the Solis is cheaper than the equivalent Sunsynk!
  11. I had over 1000 units since install over 3 years ago, and use about 2 units per month. I haven't bought anything since then, and it wasn't cut off or anything, but I had about 980 units on my meter. This caused issues for me when they did the meter upgrades, they could not give me more than 500 units, apparently they have never seen someone with no many excess credits. I had to call a guy to get him to give me the codes over WhatsApp, which I punched into my Landis Gyr, apparently that solves the issue too. If you meter goes faulty there is no way to get the credits back. So while it's a great way of accumulating units, there is risk, I would not recommend it unless it's such a small amount that you are prepared to risk.
  12. Mine works fine on V4.5.8 https://portal.riotsystems.cloud/dashboard
  13. @Keith Gough recently released this training video on common problems with RCDs / RCBOs. And at 11H00 he covers "Do you need an earth rod"? https://www.youtube.com/watch?v=35RqpeenO7g
  14. Hager, but the cost is reflective of the quality.
