Uptime is the percentage of days in the system's lifespan where energy production is not zero.
Common Causes for downtime
- Internet Connection Lost
- Power Outage
- System Maintenance
- System Error
- Snow on panels
- Hardware Failure
Data loss is more prevalent than actual production loss because in many instances the system continues to generate energy but fails to log it. Changes in homeownership or internet services are the leading causes of 'downtime' in our database. Enphase Gateways store data on the harddrive for many months without an internet connection, meaning some data gaps will be filled in as soon as a connection is re-estsbished.
