Ongrid solar inverters have high working efficiency and reliable performance. They are suitable for installation in remote areas where no one is maintaining or on duty. They can maximize the use of solar energy, thus improving the efficiency of the system. Below I will introduce to you the installation precautions for installing grid-connected inverters.   1. Before installation, you should first check whether the inverter has been damaged during transportation. 2. When selecting an installation site, make sure there is no interference from other power electronic equipment in the surrounding area. 3. Before making electrical connections, be sure to cover the photovoltaic panels with opaque materials or disconnect the DC side circuit breaker. When exposed to sunlight, photovoltaic arrays will generate dangerous voltages. 4. All installation operations must be completed by professional technicians only. 5. The cables used in the photovoltaic system power generation system must be firmly connected, well insulated and of appropriate specifications. 6. All electrical installations must meet local and national electrical standards. 7. The inverter can only be connected to the grid after obtaining permission from the local power department and after professional technicians have completed all electrical connections. 8. Before performing any maintenance work, you should first disconnect the electrical connection between the inverter and the grid, and then disconnect the DC side electrical connection. 9. Wait at least 5 minutes until the internal components are discharged before performing maintenance work. 10. Any fault that affects the safety performance of the inverter must be eliminated immediately before the inverter can be turned on again. 11. Avoid unnecessary circuit board contact. 12. Comply with electrostatic protection regulations and wear an anti-static bracelet. 13. Pay attention to and obey the warning labels on the product. 14. Conduct a preliminary visual inspection of the equipment for damage or other dangerous conditions before operation. 15. Pay attention to the hot surface of the inverter. For example, the radiator of power semiconductors will still maintain a high temperature for a period of time after the inverter is powered off.
