  1. Received the attached Pylontech battery performance curves from Pylon support if anyone is interested...Seems like these batteries can be run hard (high DoDs) and still last for many years 48V Pylontech Battery Performance 0320.pdf
  2. My grid charge settings are similar to the video. Cloudy overcast day in Gauteng today and my PV barely got the 3% charge in at 40% level. Although I had grid charge to come on at 3pm - this did not happen......guessing that on the Battery Setting page, Start is set at 30%, so grid charge would not have been activated? what settings have you seen work for grid charge?
  3. just saw this now.... not pulling much more than 300w after 9pm, so will be tight but was still at 55% SoC this morning at 5am. Will need to monitor it over a period time and adjust for typical use..... or save up for another 3.5 Pylon
  4. Good question! These were the settings from the installer, except I have now changed the SoC as shown. It does not work that way however as the batteries charge up from PV from first light with no draw from grid.... there may be another priority setting to favour PV before grid.
  5. @justinschoeman Not sure why you would need to do this as I understood the Smart Load function caters for most of this anyway. It does not appear that it draws from the battery or grid, but only from PV and only when there is excess capacity. Unfortunately there is no Deye material to explain this but perhaps SunSynk explain the operations better - they are basically the same inverter There is a short YouTube video:
  6. Deye has a similar page setup except it just shows "Batt" and not SoC %
  7. ck the 3 dots on top right and select device details, then go to inverter and stats. Have set it to storage and see the batteries now - thanks this was very useful Do you know how to reduce the SoC limit on the Deye - not obvious on the menus I went through
  8. @FixAMess the Deye seems to hover around 99% SoC most of the time, going to 100% but not staying there for long. wonder if this helps??
  9. I have two pylons US3000 on a Deye inverter. Also had some comms issues but resolved this...sounds obvious but make sure the master / slave connection is right. For some reason RS comms did not show the correct readings and these bounced around. The CAN protocol seems to work correctly and displays the info consistent wiht my use. Deye and Sunsybk should be exactly the same hardware with Sunsynk having some tweaks on the software, as I understand. Read somewhere that the Pylons are self learning so may need to "settle in" to your setup
  10. @Youda The Deye inverter uses the Solarman app to monitor the system - can you recommend a better app? for some reason I do not see the Pylons on the App so cannot monitor this
  11. Too many acronyms for a noobie.... Going to reset the SoC limit to 50% before going to grid today... that should balance using the batteries more efficiently, allowing some leeway if there is power outage, and preserving the battery life!
  12. Thanks Justin and Achmat: Not sure what the CT sensor is but it is obviously configured to power just the household load. There is definielty no export to grid as I can see that the power generation of the PV matches the house load. This is the excess capacity that I want to channel to a spare geyser
  13. YES, my bad. SoC is at 80% when the inverter switches to grid. Guess what I am trying to understand is what is a level to take SoC down to and keep battery life to ten years +. Someone mentioned that if I draw power to SoC of 50% then the life of the battery drops exponentially!
  14. Yes, the alarm is set to scream if it goes below 20%, but this only happens when no grid power. On a normal evening, it goes to grid at 80% DOD which is probably wasting the very expensive battery capacity and potential. Correct?
