How to Install the LG Solar Panel System

1. Read and follow the installation instruction manuals provided with the solar panel and micro-inverter
2. Secure the Unirac roof attachment standoffs and flashing to the roof joists; add caulk as needed
3. Attach Unirac mounting rails to the roof attachment standoffs using supplied hardware
4. Secure the micro-inverter(s) to the Unirac mounting rails using the supplied grounding lugs
5. Connect the solar panel output cables to the micro-inverter input cables
6. Secure the solar panel(s) to the mounting rails using the supplied mid-clamps and end-clamps
7. Connect the AC inverter cables along each row of modules; Connect multiple rows using the AC inverter extension cable; Connect the last micro-inverter cable to the AC transition cable
8. Connect the AC transition cable to a junction box or AC Safety Switch disconnect box (optional, varies by location)
9. Connect a PV wire from the junction box or safety switch to an open 20A circuit breaker in the household electrical box
10. Contact the local electric utility company to schedule connection to the grid
