SolaX Power

The solax integration connects Home Assistant to Solax solar power inverters. Solax inverters may be connected to a home Wi-Fi network and expose a REST API. This integration retrieves information such as photovoltaic power production, battery levels and power, and how much power is being fed back into the grid.


To use the Solax sensors in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
  - platform: solax
    ip_address: IP_ADDRESS

Configuration Variables

ip_address string Required

The IP address of your Solax system.

port integer (Optional, default: 80)

The port number

Optional template sensor

If you would like to convert the values from multiple panels or view the total power the house is using, you can use the template platform.

# Example configuration.yaml entry for template platform
- platform: template
      friendly_name: "Total PV Power"
      unit_of_measurement: "W"
      value_template: "{{ (states('sensor.pv1_power') | float) + (states('sensor.pv2_power') | float) }}"
      friendly_name: "Load Power"
      unit_of_measurement: "W"
      value_template: "{{ (states('sensor.power_now') | float) - (states('sensor.exported_power') | float) }}"


Inverter models with newer firmware (and also those using devices like PocketWifi) no longer expose an API when connected to your wireless network, they do however continue to expose it on their own broadcasted SSID. To use this sensor in this case it is necessary to set up a reverse proxy with something like NGINX and use a Raspberry Pi (or similar) with two network connections (one being Wi-Fi that connects to the inverters SSID).

Example NGINX configuration
