Design aspects of solar PV stations to ensure safe maintenance

New users in solar energy are interested in questions about updating or strengthening the existing wiring and fuse. Today we will discuss the minimum requirements for the design of a solar station and the installation of a solar station and safe operation. To begin with, it is important to understand the number of solar panels and ensure the installation of an inverter with sufficient power, which will convert direct current into alternating current. All cables to the inverter must be calculated at the stage of designing the solar station to withstand the short-circuit current in the part of the direct current.

The inverter itself can be secured with a DC fuse. After that, the safety fuse of the inverter is connected to the inputs. A very important parameter is voltage and current control at the inverter inputs. They should not exceed the maximum allowed parameters in separate groups. Sometimes, due to the large distance between the inverter and the meter, it is impossible to lay a cable of the appropriate thickness. In this case, it is necessary to limit the output power of the inverter. This phenomenon leads to losses during peak hours, but at the same time it gives an opportunity to increase the number of solar panels in the design of solar stations and fills the production schedule well in the morning and evening hours when the generation drops.

It is important to note that in standard projects, when there is no need to limit the output power of the inverter, it is necessary to use a cable of the appropriate thickness in the solar station project and a fuse at the meter that will withstand and disconnect the system in the event of a short circuit.

The use of the correct components in the design of solar stations will ensure safe generation of electricity for many years.
