4. Monitoring System
This organises information from your smart meter and displays it in a useful format. This shows real-time generation, overlaid with your consumption so that you can see how much you’re saving.
6. Battery (Optional)
Any excess electricity that you generate and don’t use can be stored in a battery for later use.
7. Back-up generator (Optional, if off-grid)
If you’ve chosen to go off-grid you may like to have a back-up generator to ensure you have continuous electricity supply.
