Photovoltaic power generation is strongly supported by national policies and is becoming more and more well-known to the public. As a key component of photovoltaic power generation systems, photovoltaic inverters have also received a lot of attention, but some people still have only a limited understanding of photovoltaic inverters. So, how to install a photovoltaic inverter? How to choose the installation location?

How to install a photovoltaic inverter? The precautions are as follows:

1. Before installation, you should first check whether the inverter is damaged during transportation.

2. When selecting a site for installing a photovoltaic inverter, ensure that there is no interference from any 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 circuit breaker. The photovoltaic array will generate dangerous voltage if exposed to sunlight.

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 be connected to the grid only after obtaining permission from the local power department and all electrical connections have been completed by professional technicians.

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

9. Wait for at least 5 minutes until the internal components are fully 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 wrist strap.

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

14. Before operation, conduct a preliminary visual inspection of the equipment to see if it is damaged or in other dangerous conditions.

15. Pay attention to the hot surface of the inverter. For example, the heat sink of the power semiconductor will remain at a high temperature for a period of time after the inverter is powered off.

How to choose the installation location of the photovoltaic inverter?

1. Do not install the inverter in direct sunlight. Otherwise, it may cause excessive internal temperature of the inverter, and the inverter will operate at a reduced rating to protect internal components. Even excessive temperature may cause inverter temperature failure.

2. The installation site should be strong enough to support the weight of the inverter for a long time.

3. The ambient temperature of the selected installation site is -25°C~50°C and the installation environment is clean.

4. The humidity of the selected installation site shall not exceed 95% and there shall be no condensation.

5. There should be enough clearance in front of the inverter to facilitate data observation and maintenance.

6. Try to install it away from residents' places as it will generate some noise during operation.

7. Make sure the installation location will not shake.

The efficiency of the photovoltaic inverter affects the overall efficiency of the photovoltaic power generation system. Its installation matters cannot be ignored and requires professional operation to ensure that a suitable and stable operating environment is provided for the photovoltaic inverter.
