  1. All you will get here are rumours. Wait until your municipality submits their application to NERSA and then you can evaluate from there.
  2. Why don't you just use the solarman ingtegration for HA?
  3. I'm not sure about different versions and all that. I can say that mine is 680mm x 420mm x 233mm. And yes, the hardware is identical in every way to the SunSynk.
  4. Just to clarify. Do you need 1kW for 2 hours = 2kWh, or 1kWh for 2 hours at 0.5kW?
  5. I looked into Hoymiles while designing my system. You only need the one DTU for your system. DTU pro adds GPRS while normal DTU is only WiFi (which should be sufficient for most residential cases). As others have mentioned, you might also want to consider Solis grid-tie inverter. It works out quite a bit cheaper than the Hoymiles and would be my recommendation, if you don't require panel level monitoring or optimisation.
  6. In which case you needn't pay much attention to the Eskom discussions. Keep an eye open for your municipality's submission to NERSA, that's the one that will be applicable to you.
  7. Are you an Eskom direct or municipal customer?
  8. If anyone was wondering, I tested this today and sadly the meter does in fact turn forward when attempting to feed in.
  9. That's not impossible. I did have a firmware update recently
  10. Strangely enough after about day 2 I haven't heard the sound again. Not sure if it's stopped or I just became deaf.
  11. Click on the red arrow and then you should get the following two screens.
  12. I believe it's been established that these units aren't supercaps but in fact LTO cells.
  13. As requested, share pics of the system work mode screen.
  14. You only need the CT is you have loads before the inverter. It's easy for the inverter to know if it is sending power back along the lines or not. The trick is to know how much to send if it's not zero.
  15. The deeper you use the battery, the shorter its cycle life yes. But also, it is rated for 3000 cycles at 1C at 100% discharge, which is more than 8 years (and then 60% of the battery remains). It also has built in protection which will turn the battery off before it goes too low. The point is, you paid good money for the battery, you may as well use it.
  16. Inverter will charge the battery from grid up to the percentage set for that time slot and if grid is selected. For the time you sent the message it is set to 35%, so it won't be charging a battery that is already at 66%.
  17. Welcome. Enjoy the forum. For interest sake, where are you based?
  18. That helps. I guess a geyser is hardly ever 20 degrees, so one probably needs less. I had a quick look now and my home assistant energy dashboard tells me we averaged about 4.5kWh per day on our 150l geyser this last week (family of 5).
  19. What is the maximum draw from your batteries? Ensure the cables are able to handle this and then fuse to protect the cable. A single Hubble can do 100A, so 25mm cable and fuse between 120A and 160A should do.
  20. One cycle is 100% discharge and charge of the battery, or stated otherwise using the capacity of the battery once. The increments in which it is used doesn't matter. You can do 100% to 0% and back again, or 100% to 90% ten times, both are seen as one cycle.
  21. From your bill you are an eThekwini customer. Eskom's billing structure doesn't apply to you.
  22. I know many people feeding back in to the grid. I don't know anyone who has ever been fined for this.
  23. Or he can wait for a cloudy day and catch up then?
