15 precautions for the installation and maintenance of hybrid solar inverters

1. Before installation, first check whether the hybrid solar inverter is damaged during transportation.
2. When choosing the installation site, make sure that there is no interference from any other electronic equipment around.
3. Before electrical connection, make sure to cover the photovoltaic panel with opaque material or disconnect the DC side circuit breaker. Exposure of photovoltaic arrays to sunlight can generate dangerous voltages.
4. All installation operations must be completed by professional technicians.
5. The cables used in the photovoltaic system and power generation system must be firmly connected, well insulated, and of suitable specifications. 6. All electrical installations must comply with local and national electrical codes.
7. The hybrid solar inverter must be approved by the local power department before it can be connected to the grid, and all electrical connections are completed by professional technicians.
8. Before any maintenance work, the electrical connection between the inverter and the grid should be disconnected first, and then the electrical connection on the DC side should be disconnected.
9. Before maintenance, wait at least 5 minutes until the internal parts are discharged.
10. Any fault that affects the safety performance of the hybrid solar inverter must be eliminated immediately before starting the inverter again.
11. Avoid unnecessary board contact.
12. Comply with electrostatic protection regulations and wear anti-static bracelets.
13. Pay attention to and obey the warning signs on the product.
14. Check the equipment for damage or other dangerous conditions before operation.
15. Be aware of the hot surfaces of the hybrid solar inverter. For example, power semiconductor heat sinks remain hot for a period of time after the hybrid solar inverter is powered off.
