 The easiest way to use MaxPower is with docker. Use the files from [the dashboard sample](usage-with-docker-compose) to run a MaxPower container along with Prometheus and Grafana for a local dashboard stack which runs perfectly fine on a Raspberry Pi.
 
+### Connection issues and regular restarts
+
+I found that the inverters turned inaccessible after ~24 hours of running MaxPower. Strangely enough, only restarting the MaxPower-container fixed it. I checked the code but could not find any leaks or possible connection issues. That's why I went with the crowbar tactic and added an additional docker container in my docker-compose.yml that restarts the MaxPower-container regularly. You might need it too:
+
+```yaml
+  restarter:
+    image: docker:cli
+    restart: unless-stopped
+    volumes: ["/var/run/docker.sock:/var/run/docker.sock"]
+    entrypoint: ["/bin/sh","-c"]
+    command:
+      - |
+        while true; do
+          echo "Restarting MaxPower ..."
+          docker restart maxpower # use the service name of the MaxPower container defined in your docker-compose.yml
+          sleep 3600
+        done
+```
