I have a Solax Inverter for battery storage connected via an Ethernet cable to my local LAN.
The inverter via the Solac Website and Solax APP can make the inverter force charge the batteries on a manual configuration via these but want to try and do this via HA so I can control this more dynamically.
I know this can be done as “Social Energy - the company” did the same with there config but just cant seem to find these functions via Solax’s Cloud API and cant seem to connect locally to the IP address of the unit
Octopus Energy are now providing “Power-up Scheme” that lets you use as much power as you like for free at certain times so want to automate this
I’m just about to attempt this myself. The key seems to be the octopus energy ‘electricity rate’ entity. I have been manually changing the forced charge period 2 active times to pick up the ad hoc free/cheap power which works ok for testing.
So my period 1 is the fixed cheap EV rate 23:30 - 5:30 which I don’t touch, except every night at 23:00 I update the charge value based on the forecast.solar power forecast for the next day, which has been working well for the last few years.
Why are you using Solax ethernet BTW? I’m pretty certain you need the web version of Solax to control the inverter with HA, which is WiFi only AFAIK. That’s how I’m controlling mine currently and I’ve never got it to work with Ethernet as much as I would prefer it.
