+
+The `solaredge` platform uses the [SolarEdge Monitoring API](https://www.solaredge.com/sites/default/files/se_monitoring_api.pdf) to allow you to get details from your SolarEdge solar power setup and integrate these in your Home Assistant installation.
+
+<p class='note'>
+The SolarEdge Monitoring API has a daily rate limit of 300 requests. In order to stay under this limit, and alow for some additional requests, the `solaredge` platform will update the site overview every 5 minutes.

+## {% linkable_title Configuration %}
+
+To use the SolarEdge sensors in your installation, add the following to your configuration.yaml file:
+
+{% raw %}
+```yaml
+# Example configuration.yaml entry
+sensor:
+  - platform: solaredge
+    api_key: API_KEY
+    site_id: SITE_ID
+    monitored_conditions:
+      - current_power
+      - last_day_data
+```
+{% endraw %}
+
+{% configuration %}
+api_key:
+  description: Your SolarEdge Site API key.
+  required: true
+  type: string
+site_id:
+  description: The id of your SolarEdge Site.
+  required: true
+  type: string
+name:
+  description: Let you overwrite the name of the device in the frontend.
+  required: false
+  default: SolarEdge
+  type: string
+monitored_conditions:
+  description: SolarEdge Site information to be monitored. The following conditions can be monitored.
+  required: false
+  type: list
+  default: current_power
+  keys:
+    life_time_data:
+      description: Lifetime energy generated at your SolarEdge Site in Wh
+    last_year_data:
+      description: Energy generated this year at your SolarEdge Site in Wh
+    last_month_data:
+      description: Energy generated this month at your SolarEdge Site in Wh
+    last_day_data:
+      description: Energy generated today at your SolarEdge Site in Wh
+    current_power:
+      description: Current generated power in W
+{% endconfiguration %}
+
+If no **monitored_conditions** are specified, only **current_power** will be enabled.
+
+### {% linkable_title Full configuration sample %}
+
+A full configuration entry would look like the sample below.
+
+{% raw %}
+```yaml
+# Example configuration.yaml entry
+sensor:
+  - platform: solaredge
+    api_key: API_KEY
+    site_id: SITE_ID
+    name: SolarEdge
+    monitored_conditions:
+      - current_power
+      - last_day_data
+      - last_month_data
+      - last_year_data
+      - life_time_data
+```
+{% endraw %}
+
+In case you would like to convert the values for example to kWh instead of the default Wh, you can use the [template platform](/components/sensor.template/).
+
+{% raw %}
+```yaml
+# Example configuration.yaml entry for template platform
+sensors:
+  platform: template
+  sensors:
+    solaredge_last_year_data_template:
+      value_template: '{{(states.sensor.solaredge_last_year_data.state | float / 1000) | round(2)}}'
+```
+{% endraw %}
