Four ways to use
your stored energy

☀️

Self-Use

Prioritises using your solar energy first, storing excess in the battery, and only drawing from the grid when needed. Maximises self-consumption and reduces bills.

🔋

Backup

Reserves a set amount of battery capacity for power cuts. When the grid goes down, the X1-IES switches to backup in under 10ms, keeping essential appliances running.

💷

Feed-In Priority

Exports excess solar energy to the grid to earn income through the Smart Export Guarantee. Best for homes that generate more than they consume during the day.

Time-of-Use

Charges from the grid during cheap off-peak hours and discharges during expensive peak periods. Works with tariffs like Octopus Agile and Intelligent Go to maximise savings.
