Step 5 · Electrical Wiring and Connections

Connect the solar panels in series or parallel according to the system design using MC4 connectors or specified wiring. Route the DC wiring from the panels to the inverter location. Mount the inverter securely and connect the DC input from the panels. Connect the inverter's AC output to a dedicated breaker in the main electrical panel or a sub-panel. Ensure all electrical connections are secure, properly insulated, and comply with electrical codes.
