  1. Yes. It will then basically just be a backup solution.
  2. On the prepaid meter. You need to apply to CoCT for a bidirectional prepaid meter. All normal prepaid meters will either trip or run the units down when feeding into the grid. You cannot feed in with a normal prepaid meter. CoCT does charge R12K for the bidirectional meter. I would suggest to just set the system to zero export after batteries are full and loads are met. Unless you really want excess to feed into the grid then you will need to buy the bidirectional prepaid meter from CoCT for R12k.
  3. I'm not familiar with the system but most if not all hybrid or grid tied inverters has a setting to select zero export. There would be a CT sensor on the main grid line to detect this and stop the inverter from back feeding into the grid. Can you perhaps share some of your settings screens?
  4. Lower volts will require more amps for the same watts. This will mean that you will need thicker cables for the same amount of electricity. A 24v system will need 70mm² cable to supply 5kw from the batteries. A 48v setup will only need 25mm² cable for the same application. Thicker cables are harder to work with and costs significantly more.
  5. On this pic my loads were 8.61kw. The inverter took up to 8kw from solar and batteries and the balance from the grid. The 8kw inverter can do this up to a maximum of 19.8kw which I don't think I'll ever manage to reach. The only time you will most likely trip the inverter is if the grid is down and your loads are more than 5kw, or 8kw in my case.
  6. Hi The 5kw inverter has a passthrough amount of 48A or 10 560w. What this means is that if your loads on the inverter are 8kw it will pull the maximum available from solar and batteries (if you set to use batteries) up to 5kw and the rest will be pulled from the grid. I have the 8kw and my load once exceeded 9kw. Solar provided 6kw, 2kw from batteries for a total of 8kw for dc to ac and thelance of 1kw was taken from the grid. Your single pylontech battery is also limited to discharge at 37A or 1 776w. You can put everything on the inverter and not split but then the proble
  7. CoC requirements are that DC and AC cabling are not in the same trunking.

    Pylontech

    That battery temp is a bit on the high side. My pylontech batteries are getting up to 30°c on a very hot day in Somerset West. The lights on the battery should tell you if they are flat. Does the inverter or battery not have an error when it switches off?
  9. They have a Web portal. You can also check the store for an app called Solarman. They have 4 android apps but not sure if they have any iOS apps.

  11. Nice install and welcome to the sunsynk club. There's another thread in the questions and answers section here where you can hook up a Pi directly to the inverter and get more up to date data.
  12. The pylontech battery management system limits the charge and discharge currents. If you have 1 x 3.5kw pylontech battery then it willing this to 1.75kw. I have 3 x 3.5kw pylontech batteries connected to my 8kw inverter and it will only charge you discharge up to 111A or about 5.25kw. This only applies when running only from batteries. If there's solar or grid available it will increase the output and blend from these other sources. Edit Pic from my inverter indicating charge and discharge limits. The BMS will change these values based on the SOC of the battery.
  13. Can you get the grid frequency? It drops during load shedding.
