  1. OK so initial test with everything connected as it would be every day and inverter supplying load from PV gives 0V AC between N and E on a plug. I did not unplug anything else. In this case Grid is still connected to the inverter,along with PV and batteries. Disconnecting grid from the inverter via the breaker into inverter also gives 0V AC between N and E. This is still with load being supplied by PV. Disconnecting the grid and PV from inverter, so purely batteries still gives me 0V between N and E. I take it this is a good sign, but the test to confirm all is 100% would be with the EL tester as indicated above.
  2. Yes, exactly this. This is also in Li mode where I have seen 1) My datalogger stop collecting data points for a random period of time and 2) Had the power trips. In USE/US2 mode none of this has happened.
  3. OK, please let me know what Mahone says and why this is so.
  4. If your battery is at 100% SOC, then yes. Wondering what it will do when you set 01 to SOL? Still trying to figure what exactly the difference is between SOL and SBU? On the user guide I have it says exactly the same thing...
  5. Agreed, seems stupid to me as well as I would think once the BMS is happy with the SOC it should just cut off charging/drop down to mili-amps. Those that know better might not agree and have the correct answer. But please do ask Mahone this question again and why it is controlled by the inverter and not the BMS. I expect, based on what I have seen my side, that 800W to increase as PV becomes available and your setting 02 to increase along with that. And yes for it to revert to battery once it reaches 100% SOC, but lets see.
  6. Yip, would make sense at that SOC. When that close to full it will draw very little for charging.
  7. OK, yes this is the issue as discussed above. Mahone will tell you the same story about the auto discharge safety feature. Option 2 and 11 are overridden when you put it in Li mode and this is now controller by the BMS. That value will constantly change depending on the battery SOC. If you battery gets drained and there is PV available you will see it kick in and the charge value will increase again. What is your battery SOC at that time?
  8. OK WOW WOW WOW...so you saying with me running this Growatt SPF5000TL and it running on batteries/solar and I touch a live wire, EL wont trip? Easy method to confirm this? Would this be a valid test when running on batteries? How about when running on grid via inverter (changeover switch still on Inverter)? @HarrycHow were you testing if it trips or not?
  9. OK cool. That is the latest major versions. There have been BMS specific firmware sent out depending on what batteries you run, etc. This was to fix specific comms issues. BUT saying that I am still to hear of someone running Dyness batteries in Li mode(05) profile L01 and not occasionally getting warning 04 & 20 and the inverter restting/house power tripping.
  10. Whats up? Did you get the relevant firmware from Growatt?
  11. Any suggestions on how to go about this? Think it is a great idea, just need to sort out the logistics.
  12. Thats exactly what it does. See previous page for discussion on this.
  13. Anyone have an explanation of how to wire such a setup? Using a Basic Sonoff switch. I take it the relay/contactor replaces the CB?
