Solax Automations

Logic

We have a strategy selector updating our helper entity. These automations are realizing the strategy towards the solax. Remember the Self Use Mode that we are using as setup in the components? That will be our No action strategy. There are however few cases there we want to hande the invertor with remote control. If you want to truly understand, please read docs.

Handled situations:

• Charging
• Discharge
• Sell to grid
