  1. Think the means the electric hazard signs that need to be on the DB and the labels. I could be wrong though.
  2. Hi there. that’s a really big system. I have 1 concern though. I think the inverters are too close together and there’s not enough spacing between them. I am planning to install a second 5 kw sunsynk in parallel and have been trying to find the minimum spacing and I have seen in some manual 1m, others have told me 0.5m. Yours looks like 10 or 15cm. Remember the 8 kw units have fans on the sides and blow from left to right so one of the top 2 units are going to overheat unless your have some sort of active cooling in the room. Please check this point befo
  3. No, during load shedding the battery will continue to discharge until it hits the minimum soc defined by the battery specification, not this table. For example old pylontech will switch off just below 20% or 15% I think, while the new c versions will go down to 5%. I haven’t taken my battery down that far. what we do when we know load shedding is coming is disable the use timer. This will then charge the batteries to 100% and keep them charged so that you have enough capacity for load shedding. Its really easy once you get the hang of it. There’s not much to fiddle with
  4. With my config, pv is used to supply loads first and if there’s excess, it charges the battery. At 15:30, if the battery soc is less than 80%, it will used pv to supply loads first, excess will be used to charge the battery and it will use grid to charge battery up to what is defined by the bms. If the grid box is unticked, it will not charge from grid, it will use whatever excess solar power is available. If no excess solar power is available, and the battery soc is below the value defined in the table, then it will just switch over to grid to power the loads. U
  5. Correct. As long as the large loads are not on the load side of the inverter, you should be fine. If your inverter loads are too large and you have load shedding, then the inverter is going to try to pull all the power from the battery and you then run into issues.
  6. What exactly are you confused about? As others have said, it takes a bit of getting used to, but from then on, it’s pretty easy. The system mode settings is the most important screen. in my case, the first time I have configured is 01:00. At this time I have said that the battery need to be at 50%. So if before 1:00, the battery is above 50%, it will start discharging until it gets to 50% and it will then switch back to grid. I have grid enabled which means that if the battery is below 50% at 1:00, it will charge from grid until it gets to 50% and then just hold
  7. For me, I can see the remote control from my iPhone app but on android it’s not available. So it’s a bit strange.
  8. Hi. I had 2 Us3000 batteries initially, added another recently. My system is running for about 7 to 8 months now and I’ve never had any issues with not having enough battery power, or low battery warnings. During the day my loads go over 5kw without any issues. Remember, if There’s not enough battery capacity or power available, which the bms will tell the inverter, it will seamlessly pull the balance from the grid. For me, the battery is just there to buffer the solar generation during the day, to provide some power at night and to deal with load-shedding. My ess
  9. As far as I know, the earth leakage has nothing to do with the earth wire. The actual name of the device, RCD, somehow got changed to earth leakage. The RCD only has 2 wires going in, live and neutral, and 2 coming out. There is no earth wire involved. whether neutral and earth is bonded or not, the potential difference between the live and neutral is still around 230v. When bonding is there, the neutral will be at 0V and with no bonding, the neutral could be at 100V. In this case your live is then at 330V with reference to earth which is a lot more deadly. In either case,
  10. An off grid inverter is like the basic axperts. Some people connect it to the grid and use it like a ups. What @Tariqis saying is ygg BC at this is not allied to be connected Ted to the grid. You need to have a changeover to use them.
  11. What’s also important to bear in mind is the actual reliability of the device being used. for example, Even though the sonoff th16 / pow is rated for 16A, there has been various tests that show that it cannot handle this current for extended periods and sometimes burn out after a few weeks to few months. That being said, some people are using it and it’s fine. Personally, I don’t use it directly for more than 5A. If I need to switch larger currents, I use an external relay.
  12. did you get it working now? Yes, there is no total PV, You can get PV1 and PV2 and just add the 2 using the sum node.
  13. others look fine. Just to confirm. You are using the RS485 port on the inverter.
  14. its just a gate node. under flex getter, i have type set to serial.
  15. also check if queue commands and reconnect on timeout is enabled on the flex getter
