Solar Panels

Your solar panels turn sunlight into clean DC (direct current) electricity.

Solar Inverter

Your solar inverter converts solar generated DC electricity into AC (alternating current) electricity that can power your home.

Letter C

MAIN ELECTRICAL BREAKER BOX

AC electricity passes through your electrical panel to power devices in your home.

SONNEN ECO

Your sonnen eco converts excess AC electricity to DC for storage in its battery modules. When you need it, the electricity is converted back to AC— day, night, or during an outage.

Letter E

PROTECTED BREAKER BOX

A second breaker box (aka "protected loads panel") is an additional electrical panel that distributes power to critical devices in your home in an outage from your eco. 

Letter F

Meter

Your meter monitors and measures electricity used by your home and excess solar power fed into the electrical grid.

Letter G

Utility

Your utility keeps you connected to the local electrical grid, ensuring you have access to grid power when you need it.
