  1. Yeah, I wish someone could confirm the difference between these units. Surely it’s not just the same thing in a different case?
  2. I have three Sunsynk inverters that I monitor. One of them gives both “disconnect” and “connect” notifications. The other two only give “disconnect” notifications. For what it’s worth, I believe in the back-end there’s an old server (system 1) and a newer server (system 2). You select which of those you log into with your user account. And somehow in the background the inverter is also associated to one or the other of the systems. Now, the inverter I monitor that sends both notifications is on the old “system 1” whereas the two that only receive grid down messages are on the newer “system 2” server. Could be coincidence or could be a causal relationship. I don’t know. SunSynk make great kit but their dev team seem a tad shaky right now. See their implementation of the Philips Hue integration for another example of half-complete work. I still wouldn’t buy any other inverter though to be honest.
  3. Yeah, unfortunately that comes back to the problem of running cable. The non-esentials (geyser, aircon, etc.) are all close to the DB but nowhere near the inverter.
  4. The reason for a wireless (as opposed to wired) contactor would be that I don’t have Eskom power coming in to the DB, or anywhere near it. And there’s no way to run a new cable in to that location. So the entire house is powered by the inverter, which is outside the building. I have no choice. If I used a wireless contactor with transmitter out at the Eskom side of the inverter (in another building about 20m from the DB in the house) then I could have non-essential items disconnected when grid power goes down.
  5. Ok I see. So one can presumably script or configure a shutdown event from that notification? I’m not sure that would work for my needs though - I need non-essential loads killed instantly if grid goes down, or else the excess draw could trip my inverter.
  6. Thanks, sounds interesting. Do you have this working like a contactor (IOW, when grid goes down, it instantly kills the power to the non-essential loads)? If so, how does the CBI device know about the grid power going down?
  7. Thanks, I've seen those but I couldn't figure out whether they work at all when the Internet connection is down? The reviews imply that an internet connection is required, which would be a concern for me. I need a robust solution.
  8. Hi folks I see a few wireless contactors on the market but not much in the way of user reviews. Has anyone had experience with these? My situation: I’ve got an SunSync 8kva inverter powering my house (everything is on it, no non-essential separation). The inverter sits about 25m from the DB and there’s no physical way to get a second cable between the two for non-essential load. So I’m wanting to shut off non-essential loads when grid power is down and thought a wireless contactor could be the answer. Can a wireless contactor do this and are the reliable? For example, what happens if comms is lost between the transmitter (on grid side) and receiver (on DB side) is lost? I’d want it to kill the non-essential load in that kind of situation. Any thoughts or suggestions are welcome. thx
  9. Anyone heard anything further on this wireless AC smart switch from SunSync?
  10. Resurrecting an old thread here but can anyone confirm from experience that this does work? Is that 50A pass-through per phase or in total? Thanks! edit: just watched the video above and it covers this question nicely
