Why Monitor Your Solar System?
Catch Problems Early
Alerts notify you if generation drops, so you can fix issues before losing significant output.
Optimise Usage
See when you're generating most and shift heavy appliance usage to those times.
Peace of Mind
Check your system is working from anywhere, even when you're away from home.
Key Metrics to Track
Daily Generation (kWh)
How much electricity your panels produced today
Why it matters: Compare to expected output for the weather conditions
Real-time Power (kW)
Current generation at this moment
Why it matters: See how output varies with sun position and clouds
Lifetime Generation
Total electricity produced since installation
Why it matters: Track your environmental impact and ROI
Self-consumption %
How much solar you use vs export
Why it matters: Higher is better - you save more by using your own power
Battery State (if applicable)
Charge level and power flow
Why it matters: Optimise when you charge and discharge
Fault Alerts
Warnings about system issues
Why it matters: Catch problems early before they affect output

Third-Party Monitoring Options
Smart Energy Monitors
Devices like the Emporia Vue or Sense monitor your whole home energy usage, showing generation, consumption, and individual circuits.
Works with any inverterSmart Meter Apps
Apps like Loop or Hugo show data from your smart meter, including import, export, and costs. Not real-time, but good for tracking over time.
Free with smart meterHome Assistant / Solar Analytics
For tech-savvy users, platforms like Home Assistant can aggregate data from multiple sources into custom dashboards.
Advanced usersGetting Set Up
Connect Your Inverter to WiFi
Your installer will typically do this during commissioning. Ensure your inverter location has good WiFi signal.
Create an Account
Register on the manufacturer's monitoring portal and link your system using the serial number or setup code.
Download the App
Get the mobile app from the App Store or Google Play. Log in with your account details.
Set Up Alerts
Configure notifications for errors or low generation so you're alerted to any problems.
Monitoring Tips
Don't Obsess Over It
It's normal to check constantly at first, but daily variations are normal. Focus on weekly/monthly trends.
Compare Year-on-Year
The best comparison is the same month last year. Weather varies too much for day-to-day comparison.
Set Realistic Expectations
Winter generation is much lower than summer. Don't panic at December output!
Check WiFi Connection
No data often just means lost WiFi. Check your inverter's connection if data stops appearing.
