  1. I though about the same at one stage. What if you take a normal 48V lithium charger and attached that directly to your battery buss bar. You connect that to your 1kw generator With that you can go up to around 20A charging. Maybe just as a backup to keep the batteries going through the night until solar pickups again.
  2. I think the installer was in the wrong here to install 4mm2 cable. Thus limiting the inverter and any future upgrades to save R700 on the cable costs. I agree not to pass the COC on this but for the installer to fix. From the quotes I have seen a lot of installers asks design costs but in this case there was no design done.
  3. The problem is not about getting 10KW out of the inverter. The problem is 10kw into the inverter. The inverter above have a 120A AC charger for the battery. That is 120 x 54v for charging is already 6.5kw. The inverter has a maximum AC Input Current of 40 A . 40 x 240 which is 10kw. So 40 is above the rating for a 4mm2 cable
  4. Does your inverter stop suppling power to the plugs and lights when it charges the battery?
  5. How much will that inverter pull if loadshedding stops? Charge batteries - 120A - 6kw Running everything in the house that is connected. - 4kw. As now people start cooking and using the plugs. That is 10kw on a 20m 4mm2 cable.
  6. TILE ROOF HOOK for sale. 8 available. Moved to a different location. R400neg for all Randburg
  7. What if you use micro inverter on the GEN input leg?
  8. A quick solution for real time monitoring is a cheap 485 converter en raspberry pi zero w. And you install node red with a light dashboard on and then on your home router you just forward your port to access the dashboard externally. Then you can see it both internally and externally. I can get the reading but from those docs I don't know how to set change a setting. I ideally just want to change the use timer setting if I see loadshedding will catch me out.
  9. I hope they have a exchange policy for the people that bought the old logger and now wants the new Sunsynk one.
  10. Is this for a completely off-grid setup? And is there backup generator if it is cloudy for a few days?
  11. Another one, did you imports someone else's code? Try and delete everything and setup just an injector switch a function and modbus flex getter node with debug.
  12. This is my settings that is working. Node-red version : 0.20.8
  13. I have heard numerous problems with those cheap ones. Best would be to try one of these. https://www.robotics.org.za/RS485-3P?search=485
  14. What RS485 converter do you use? Might cause a problem. I run mine on a raspberry pi zero w without any problems. I go from (inverter)RJ45 -> rs485 to usb converter -> usb extention cable -> usb to micro usb cable -> rpi zero. And also use a cheap usb power adopter without any problems
  15. What is your guys polling timing set to? I have mine on 15sec. But don't want to overload the inverter data side.
  16. Looks like you need super admin rights. This mine on SOLARMAN Business. Edt: My profile even indicate that I am super admin.
  17. I know there is a option on the display under basic settings -> last tab that says lock out all changes. I wonder if that will give you the option to lock display settings update. But I agree if this is not ticked, allow the app for anyone to update the settings. Maybe have like a double check on settings update. This will be nice to change your inverter settings if you are away and let's say loadshedding hits and you want to rather up battery SOC for levels
  18. I think Johnny Wasinda is refering to putting them in 6s2p giving him 22.28A on the 22.2A limit of the inverter. That should be fine. The inverter will just clip the extra amsp
  19. Or get a geyser element that is has 2 elements build into one. Use one side for grid and other one for inverter.
  20. Looking at the size of the battery to the trunking I think it is 2.75kW each.
  21. Can be that the BMS did not fully switch on. I know on some BMS the voltage is quite low until the BMS gets the signal to fully switch on and then it rises.

    I agree, panels should have been wired in parallel. Then it would have been 40v @ 4.5A and within spec of MPPT
  23. I am sure this will work on your inverter. But I will rather go with something more commercial, like pylontech. I am not debating LBSA, I have build my own setup using their cells. But I went with it as it was a lot cheaper for a 48v setup. Their price went up quite a lot over the last year and for not much more you can get 2 x US2500 which is almost the same capacity.
  24. I was afraid of the same happening to me, so what I did was where my inverter was installed in the garage I added another grid circuit. This was taken before the inverter. As all my circuits are on the essential loads except this one. This will then be used to power heavy loads like my welding machine or something that will be to much for the inverter. And if I had a problem with the power meter I can just plug it in there.
  25. What is your battery and grid setup settings. Show us some images of your inverter settings.
