Updating Sol-Ark inverter settings from HomeyScript

Questions & Help

I have a Solar/Battery system on my house that is controlled by a Sol-Ark 15k hybrid inverter. I was looking for a method to change the inverter settings from my Homey setup based on weather events. Unfortunately, there is no App for this, nor is there likely to be one, so I decided to try and accomplish it by developing a HomeyScript to use the web interface to the inverter.
I’m still working through it, but I expect by the end of the weekend I should have a script that can be used to change the settings that control battery charging and usage into a pre-set configuration. I’ll have one for “storm prep” for days when we’re expecting significant weather that may result in short-term power outage. I’ll have another to reset to “normal” use. Another for emergency situations like Hurricane events. I intend to trigger the appropriate script based off of weather alert events.

I also do several other things during grid-outage events to reduce power usage, like switch the HVAC system off. I can still override manually, but I don’t want that eating up my batteries unless I intend to. This script will become a part of that grid-outage flow.

I don’t know if anyone else out there is using a Sol-Ark, but I’d be happy to share this once it’s working properly.
