Photovoltaic power matrix installation in the technical aspects need to pay attention to points (||)
Second, the PV grid-connected inverter installation considerations
1、Before the installation, you should check whether the inverter is damaged during the transportation.
2、When choosing the installation site, you should ensure that there is no interference from any other power electronic devices within the surrounding area.
3、Before making electrical connections, be sure to use opaque materials to cover the PV panels or disconnect the DC side circuit breaker. Exposure to sunlight, photovoltaic arrays will generate dangerous voltages.
4, all installation operations must be and only by technical personnel to complete.
5, photovoltaic system power generation system used in the cable must be firmly connected, well insulated and appropriate specifications.
6, all electrical installations must meet local and electrical standards.
7、The inverter can be connected to the grid only after receiving permission from the local power department and after all electrical connections have been made by a technician.
8.Before performing any maintenance work, disconnect the inverter from the grid and then disconnect the DC side electrical connection.
9.Wait for at least 5 minutes until the internal components are discharged before carrying out maintenance work.
10.Any fault affecting the safety performance of the inverter must be removed immediately before turning on the inverter again.
11、Avoid unnecessary contact with the circuit board.
12.Observe the electrostatic protection specification and wear anti-static bracelets.
13、Attend to and observe the warning signs on the product.
14、Initial visual inspection of the equipment for damage or other hazardous conditions before operation.
15、Pay attention to the inverter hot surface. For example, the heat sink of the power semiconductor, etc., remains at a high temperature for a period of time after the inverter is powered off.
