How to wire an inverter? Installation precautions for home systems.
1. DC Side Wiring: Series and parallel design, MC4 connector connection, DC cable selection, and operation after shielding the circuit board. 2. AC Side Grid Connection: Dedicated circuit + independent circuit breaker, bidirectional energy meter, three-phase balanced connection. 3. Grounding and Lightning Protection: Inverter casing grounding, bracket grounding, DC/AC surge protector installation. 4. Communication and Monitoring: WiFi signal testing, CAN/RS485 communication line connection, power sensor installation. 5. Safety Reminders: No "neutral wire" for DC power; operation must be performed by a certified electrician; acceptance inspection includes anti-islanding protection. 6. Acceptance Checklist: MC4 connector pull test, grounding resistance test, APP data synchronization confirmation.
