How to Install the Samsung Solar Panel System

1. Read and follow the installation instruction manuals provided with the solar panels, inverter and mounting system
2. Secure the roof attachment standoffs and flashing to the roof joists; add caulk as needed
3. Attach mounting rails to the roof attachment standoffs using supplied hardware
4. Secure the solar panel(s) to the mounting rails using the supplied mid-clamps and end-clamps
5. Connect the solar panel cables
6. Connect the last PV cable to a junction box or DC Safety Switch disconnect box (optional, varies by location)
7. Connect a PV wire from the junction box or safety switch to the SMA Sunny Boy inverter
8. Connect the SMA Sunny Boy inverter to an open 20A circuit breaker in the household electrical box
9. Contact the local electric utility company to schedule connection to the grid
