NoordSolar Posted September 1, 2021 Share Posted September 1, 2021 Are there any air conditioners available here which can manage their power usage according to the amount of Solar PV available ? ie read existing Energy meter ( SMA ) and adjust output accordingly to maximise solar PV usage?

Guest Sarel Posted September 1, 2021 Share Posted September 1, 2021 Not any that I am aware of no. What you maybe can do is use Home automation system like Home Assistand and a WiFi enabled Inverter Aircon system. You can then switch the AC according info from Solar in Home Assistant.

Sc00bs Posted October 8, 2021 Share Posted October 8, 2021 @NoordSolar You could automate it with Node Red using information it gets from the inverter, is pretty easy to do as long as you don't mind spending a few hours watching Youtube video's. My Node Red cycles through my heavy loads based on a SOC, current Solar PV production from the inverter and from the smart breaker switches (current load on the breaker when switched on) that send power to the heavy loads i.e. geysers/Borehole/Pool etc. When one geyser is up to temp the load on it drops and it can cycle to the next load. I also decide whether to switch the pool on in the morning based on solar weather forecast for the day in Home Assistant. As long as the Aircon interfaces with Node Red/Home Assistant it would not be an issue. There seem to be a few options as to how to do this https://community.home-assistant.io/t/smart-ac-control/115764 Quote Link to comment Share on other sites More sharing options...
wolfandy Posted January 27 Share Posted January 27 @NoordSolar I am using Sensibo for several aircons around the house and use the timer-function to switch units on/off based on when usually in the day I have spare PV. So not an actuals but rather patterns. But I can switch the units on/off via the app if I need to adjust Quote Link to comment Share on other sites More sharing options...
JuliusK Posted Wednesday at 10:33 Share Posted Wednesday at 10:33 I have a few of these https://www.takealot.com/vizia-smart-universal-ir-remote-wifi-amazon-alexa-google-home/PLID71884508 around the house and they integrate with Google / Alexa for voice and for manual use they have a phone app with timers etc as needed.

NoordSolar Posted Wednesday at 11:26 Author Share Posted Wednesday at 11:26 Thanks for reply - I'm looking for a different type of smart - that is Iwant to only use solar power that's being generated in the home to power the AC. So it must thrttle back when power low and increase power when more solar is available . They available in Europe Quote Link to comment Share on other sites More sharing options...
