  1. Go to the menu at the top right, tap on 'Plant Info', then go to 'System Type', and change it to 'Storage System'. Tap 'Yes' at the bottom, and then 'Done' at the top right.
  2. No I haven't. I am going to e-mail Freedom Won directly and ask them.
  3. I don't think you should assume the noise issue is fixed. I have an 8kW unit with a March 2021 manufacture date that has that noise. Local supplier didn't want to swop it out, so I spent R11k to have my installation moved from inside my scullery to outdoors.
  4. You should also check the prices on www.ecodepot.co.za. I got my Geyserwise TSE controller there for slightly cheaper than the price at the Geyserwise offices in Centurion.
  5. At my previous house I had the 5kW that didn't have that high pitched noise. I could only sort of hear it when my ear was like 5cm away, it was so quiet. But my new 8kW definitely doesn't belong in the house.
  6. It will definitely be bothersome. Put it in a garage or outside. Firstly the fans are quite noisy. There are 3 small fans, and they are either on or off, no in between speed. The sound of each of the fans is slightly out of phase with the others, making it worse than one big fan would have been. They come on when the temperature is 50 degrees. When the inverter is working hard they will come on about every 15 minutes, and stay on for like 7 minutes or so. The below graph is my temperature graph from yesterday. Mine is mounted outside in the shade. Each of those little spikes where it starts to drop off from 50 degrees is where the fans come on. Secondly there is the issue that some of the units gives a constant loud very high pitched noise. It is about 15,000Hz, so people above 40 years of age might not hear it. I originally had mine in the scullery, and after a couple of days I couldn't take the high pitched noise. It is similar to that sound you get from some cheap AC adaptors, but loud enough to cause physical discomfort in my ears. So my installer took the inverter to Sunsynk's tech support guys, and they said they won't swop it. So I had to pay my installer another R11,000 to move the whole setup outside. There was extra cabling, new weatherproof DB boxes, new trunking, and labour. They had to open up my IBR roof sheets to get the cables through. Plus I ended up with lots of drill holes in my scullery.
  7. Does anyone know where I can buy a replacement switch like in the attached pictures? It is for a Delonghi oil heater.
  8. No on the Solarman portal you can only see stuff like battery voltage, temperature and SoC. Not info on the individual cells. Is there PC software with which I can view the info via the battery's USB port?
  9. I have a Freedom Won battery with my Sunsynk inverter. Can someone tell me how I can get the cell level data to monitor it?
  10. And the same will probably happen if you open your solar panel fuse holders under load.
  11. You need to untick 'sol exp bat full'. Then your system should feed the items before your inverter (stove, a/c, geyser) but not export to the grid.
  12. It might not be a spelling mistake. That might be his actual handprint.
  13. Here is a video going over some of the basics of the Sunsynk inverters:
  14. Haha well said! My brother in law is off grid on a farm, and he is constantly checking and topping up his flooded lead acid batteries. I don't have the patience for that!
  15. I just thought I would share this article about the potential future impact on SA's exports if we don't keep up with the global trend of reducing carbon emissions. It is an interesting read: https://www.engineeringnews.co.za/article/eus-green-deal-will-have-wide-ranging-impact-on-sa-exports-cautionsvan-zyl-2021-06-25
  16. The screen might scratch at a level 6, but it will definitely survive the bend test
  17. Yes I can't wait for that new dongle. No more walking to the inverter to change settings like a cave man, haha!
  18. Sounds like you basically need a mini version of this setup: https://www.freedomwon.co.za/freedom-won-powering-the-future/
  19. I have one 8kW Sunsynk with the same battery. The battery came with a terminator for the second network port. My installer mentioned something along the lines of that he had to make up a custom network cable to be able to use the supplied terminator plug. My suggestion is to contact the Freedom Won support and ask them what to do for your specific setup.
  20. In my case it only comes from the inverter.
  21. I have also had the same problem with the high frequency noise on an 8kW unit. My previous unit at my previous residence was a 5kW unit that I used for about a year, which did not give this noise. When I got my new 8kW in May 2021 at my new residence, I had it installed in the scullery. The high frequency noise was barely audible to my installer because it is around 15,000Hz, but to me it is so loud that I could hear it from 10 metres away, and spending 10 minutes in the scullery doing dishes left me with my ears feeling physical discomfort for an hour or so afterwards. After I had run the system for 2 days, I asked the installer to take the unit back to be assessed by tech support, and he was informed by someone (I'm not sure who he spoke to, I think it might have been Shabir from Sunsynk support, not sure...) that they will not swop out the unit because that is just how the Sunsynks sound, and chances are good that if they give me another unit it will be even louder. I then had to pay my installer another installation fee to move the whole setup outside the house, which was another 2 days' work. I was quite disappointed in the supplier for not swopping out the unit. So to anyone considering a Sunsynk, put it in the garage or outside the house, as the high frequency noise seems to be the luck of the draw. (EDIT: I had the software upgraded, which did not make a difference)
  22. I don't know which version exactly. I got it in May 2020 and it had the old user interface. I only upgraded the software in January 2021 just before selling the house.
  23. Then maybe something has changed on the newer models. At my old house I had a 5kW installed about a year ago. All plugs and lights were on the load side, and stove & geyser were before the inverter (i.e. they were off when there was load shedding). If I ran my tumble dryer (3.2kW), dishwasher (2kW) and kettle (2kW) at the same time, the inverter would beep at me, turn off all power, and restart with the AC_Overload_Fault. I fell victim to this about 4 times before learning to check when my wife was busy with the tumble dryer. For that reason my new install at my new house is the 8kW version, because I don't want to be worrying about using appliances concurrently.
  24. Just to be clear, you can't run more than the inverter's rated power (5,500W) on appliances that are on the essential loads output. If you have stuff connected before the inverter (aka non-essential), and your CT is correctly installed, the inverter will show this as a load on its screen. For instance if you have a kettle on an essential plug circuit pulling 2kW, and a geyser + stove that is on the non-essential side pulling 5kW, the inverter will show a load of 7kW, and the inverter will have no problem with this. But if you try to pull more than 5.5kW on the essential side, the inverter will trip with the 'AC overload' error, and reset itself, even if Eskom power is on.
  25. Slightly off topic, but related to crypto mining. If the only thing on battery backup is the crypto mining rig, it could be justified to deduct the depreciation of the inverter and battery from the income declared to SARS, because the power system's costs relate directly to the generation of the taxable income, therefore reducing your income tax payable. But if the whole house is on backup, it is a bit of a grey area what portion of the expenses you could deduct. What are you guys' thoughts?
