Hi everyone, I’m looking for some advice on integrating my solar battery system with the Octopus Intelligent Go tariff.
I’m using a Sunsynk inverter with batteries, along with a MyEnergi Zappi charger. I’ve got Solar Assistant integrated with Home Assistant via MQTT, and I’ve also installed the solarsynkv3 add-on to access Sunsynk sensor data.
The Octopus integration is working well, and the Intelligent Dispatch sensor is reporting correctly. What I’d like to achieve is:
Preventing my batteries from discharging during allocated cheap-rate slots that fall outside the standard 23:30–05:30 window.
Ideally, I’d also like the batteries to charge during any allocated cheap slots, regardless of the time.
If anyone has tackled a similar setup or has suggestions for the best way to handle this, I’d really appreciate your input!
Hi Rob, I’m trying to achieve the same thing. I also hope to use Solar Forecast to adjust the maximum charge level. I’m doing this manually right now which helps learn the best cycles but would love this to be automated.
I’ve made some really good progress with this… but not quite there. Are you guys still looking at this challenge? If so I’d be happy to share progress. My last challenge is the Grid Charge commands for the Inverter. I might need a firmware update due to a known bug.
Yes I’m still trying. Any ideas much appreciated. I have only got as far as:
Getting the right permissions as “Business User” to control my inverter settings manually via sunsynk.net, which now works fine, but obviously isn’t automation.
Using the solarsynkv3 add-on for HA I can now download data/settings to Home Assistant, but there is no control path provided.
I have found a Knowledge Base article on getting access tokens for the SunSynk Connect API, but nothing on its capabilities or how to use it.
