  1. Looks like we've found a USB module. Hopefully it's the correct one.
  2. I was online with Johan, the developer of SMH when we tried, and no luck. I'll chat with him more about using my system as a guinea pig if he can add RJ45 serial as a connection option.
  3. Mine has a RJ45 port and I also have a RJ45 -> Serial cable. However, this setup is NOT compatible with SMH, so rather than buy a new inverter, I'm looking for the USB module which comes on the later inverters.
  4. Thanks guys, but that is not what I'm looking for. I'm looking for the actual USB interface board which installs into the inverter replacing the RG45 RS232 board.
  5. Hi 87, Please provide a link to the USB interface on Takealot? My searching skills don't seem to be able to find any.
  6. I've just sat with Johan to upgrade my installation of ICC to SMH, and unfortunately my inverter still uses the old skool serial interface. Does anyone know where I can source (locally hopefully) a USB module to work on my inverter?
  7. Still waiting for @Centurionsolar to get back to me on the upgrade. Going to try contact them direct, rather than use the upgrade form.
  8. A little earlier this evening, I started getting the VNC license expired message, thought "WTH!" and checked on the Centurion Solar Website to see if there was any news on this. I was greeted with the SMH vs ICC info, and my first thought was "Cool, finally an upgrade which is hopefully less buggy than ICC." I started reading through the sneak preview document with enthusiasm until I saw it was now changing to a subscription model. Not so cool, as I've paid for my licence, and now must continue paying monthly. I've since calmed down, and had a good think about it all. I'd still like to know how much a non ICC user must pay for the software upfront before the subscription, because I'm not buying this "Free Upgrade". Right now it looks like you have to buy a Pi and ICC license before you can upgrade. Nothing on the site about having your own Pi, and just getting a SMH license. Comes across as dodgy AF. And if a new SMH user just needs to start paying the subscription, then there is nothing free about upgrading from ICC. How about a free 6 month SMH subscription for your existing clients. Goes a long way to showing you appreciate the business we have already given you, and, lets face it, if we're happy and hooked on the software after 6 months, you'll have us signing up for the subscription with no negative feelings, rather than the "WTH!" feelings I felt a bit earlier this evening. On the other hand, I've really held off contacting Manie and paying (again) for his upgraded license, mainly because, IMHO, he's an asshole, and that same attitude oozes from his website, and also because I'm not convinced his later versions are that much better than the CS-ICC version I've been using. On the other other hand, the feature list of SMH looks very impressive, and if it works as well as it claims, doesn't crash every day, or freeze up every time I VNC in, I could live with R50 a month. In any case, I've registered for the upgrade to SMH, so let's see what Johan can do.
  9. So there I was busy working from home, and the power just went out. Go check the two DBs and nothing is tripped on either, but there is a distinct burnt smell. Inverter showing error 56 (battery circuit open), so I pop open the fuse box, and the negative is tripped. I open up the fuse holder and see the 100A is blown. No high loads were happening at the time. Batteries were charging, normally by what I see in ICC, so I'm stumped as to what happened. For the time being I've turned off the batteries and inverter, and running purely on grid, but before I go off and get a new fuse and fuse holder, I'd love it if anyone can give insight into what might have happened. From what I can see, both batteries appear fine, as does the inverter, but I won't know till they are connected again, although ICC reported them as healthy so I'm hopeful.
  10. Thanks all. Looking back through the history, it's tripped 4 times, 42A, 49A, 26A, and yesterday at 27A. Not a great record for one month. Definitely looking like it's faulty. Breaker is warm to the touch when I've been there to catch it. Going to play it safe and replace the breaker, and the wiring for that section.
  11. I have 3180W of PV panels configured to output between 80v and 100V. At peak output the voltage is around 86V. The peak Wattage I see is 2800W, but usually closer to 2500W. When I redid my system recently, I installed an Onesto 250/500VDC 6kA 63A double break circuit breaker. I had nothing previously and this one seemed the closest match to what my panels put out. Since then, the breaker is tripping, usually late morning, and not every day. Not only is this annoying, as I'm at work and can do nothing about it until I get home, but is wasting precious solar to charge my batteries. Looking through ICC outputs, I can't see anything unusual. I've even lowered the PV charging amps in case there was some sort of overload causing the issue. The attached image is from today when the CB tripped. As you can see, looking pretty normal until the sun suddenly disappears out of the sky. Any ideas?
  12. I sold mine to Battery Center in Roodepoort. Got R11 per kg.
  13. I also saw this sort of thing happening at the low end of the charge scale too. Batteries got down to 21% and stayed there. I didn't wait more than 5 minutes to let it get to 20% so ICC could switch to grid and start charging. Would hate for this to happen to someone, and their batteries accidentally drain down to 0% because the BMS was still showing 21%. I have since set my min battery switchover SOC to 25%.
  14. Thanks very much. I didn't use to have the luxury of putting everything right by the DB board, only about 5m, but the wires were already there so that's what I used. Only now that I've gone from 500kg of AGM batteries to 60kg of LiFePO4 can I make it all fit in that corner. That's great you are getting such good use out of the batteries. Sadly, where mine were before was in the garage, where temps are pretty much always above 40C...a real battery killer, so I'm happy to have gotten 4 years out of them. The labels are just printed on my laser printer and scotch taped to the inverter. It's kinda temporary. Will be getting some decent adhesive vinyl labels made up soon. A lady near where I live, has all the materials and printers to do it nicely. She already made my warning labels...
  15. When connecting batteries in series, you add up the voltages, so 4x 12V 105Ah batteries gives you a 48V 105Ah string. When connecting batteries (or strings) in parallel, the voltage remains the same, but the Ah increases., so 2x 48V 105Ah gives you 48V 210Ah. Not recommended to go with more than 2 strings in parallel. To get the really big Ah capacity battery banks, the easiest way is big Ah batteries with low voltages, so a single string of 24x 2V 500Ah batteries = 48V 500Ah in a single string.
