PV inverter is a common inverter product,you can convert the direct current to alternating current,has a certain application in various electronic devices.When we install the PV inverter process needs more attention to the problem,today I will introduce specific installation point of PV inverter,hope can help to you.

PV inverter installation points:

1.Before installation we should first check whether photovoltaic inverter has not been damaged during transport.

2.When selecting the installation site,you should ensure that no interference to any other power electronic devices in the surroundings.

3.Prior to making electrical connections,be sure to use opaque material photovoltaic panels cover or disconnect the DC circuit breaker.Exposure to sunlight,PV arrays will produce dangerous voltages.

4.All installation and operation must only be performed by qualified personnel.

5.The photovoltaic power generation system used in the system cable must be connected securely,good insulation and appropriate specifications.

6.All electrical installations must meet local and national electrical standards.

7.Only after permission by the local power sector by professional and technical personnel complete all electrical connections before the PV inverter grid.

8.Before performing any maintenance work,first disconnect the inverter connected to the electrical grid,and then disconnect the DC side of the electrical connection.

9.Wait at least 5 minutes until the internal components discharged before they carry out maintenance work.

10.Any impact on the safety performance of photovoltaic inverter fault must be removed immediately before they turn on the inverter again.

11.To avoid unnecessary contact with the circuit board.

12.To comply with ESD protection specifications,wear an antistatic wrist strap.

13.Pay attention to and comply with the warning label on the product.

14.Before the operation initial visual inspection equipment for damage or other dangerous state.

15.Note that the inverter hot surfaces.Such as heatsinks of power semiconductors,etc,within a period of time after the power inverter,it remained at a high temperature.
