How to install photovoltaic inverters
Precautions are as follows:
Before installation, the inverter should be checked first to see if it is damaged during transportation. When selecting the installation site for the photovoltaic inverter, it should be ensured that there is no interference from any other power electronic devices in the surrounding area. Before electrical connection, be sure to disconnect the DC side circuit breaker. All installation operations must be completed by professionals. The cables used in the photovoltaic power generation system must be firmly and well insulated. All electrical installations must meet the requirements of the power grid and electrical standards, and must be approved by the power company and completed by professional technicians before the inverter can be connected to the grid. Before any maintenance work, first disconnect the electrical connection between the inverter and the grid, and then disconnect the DC side electrical connection. Wait for at least 5 minutes until the internal components are discharged before performing maintenance work. Any malfunction that affects the safety performance of the inverter should be eliminated immediately before the inverter can be restarted to avoid unnecessary circuit board contact. Comply with electrostatic protection specifications, wear anti-static wristbands, and pay attention to and comply with warning signs on the product. Before operation, visually inspect the equipment for damage or other dangerous conditions. Pay attention to the surface of the inverter and its back heat sink. After the inverter is powered off for a period of time, it still maintains a high temperature. Do not burn yourself.
