The order of priority

How the inverter decides where power comes from

1 · SUN FIRST

Solar runs the home

Whatever the panels produce goes to your appliances first. It's the cheapest energy you'll use.

2 · STORE THE EXTRA

Surplus charges the battery

Midday surplus fills the battery for the evening, when use peaks and the sun is gone.

3 · BATTERY AT NIGHT

Stored solar after dark

The battery runs the home overnight but keeps a reserve so it's ready if the grid goes down.

4 · GRID AS BACKUP

The grid fills the gaps

The grid only supplies what's left. During a power cut the inverter disconnects from the grid and keeps you running.
