This depends on the material of the solar panel. First of all, if the surface material is PET, it is about 3-5 years, ETFE is about 5-6 years, and glass is about 20-25 years.
Photovoltaic inverter, as a DC-AC conversion power adjustment device, is divided into two parts: boost circuit and inverter bridge circuit, mainly composed of semiconductor devices.
Selection skills of photovoltaic high-frequency inverters
1. Confirm that your photovoltaic power station is suitable for installing high-frequency inverters with high power
Depending on the input source, connection method, output voltage waveform, etc. of the application, solar inverters are divided into the following 17 main categories.
Understand common high-frequency inverter alarms, accurately determine the cause of high-frequency inverter alarms, and make high-frequency inverters run smoothly.
When it comes to the development trend of photovoltaic high-frequency inverter products, as the types of power stations become more and more complex, the product types of photovoltaic high-frequency inverters will be more diversified to meet the needs of different application scenarios. Specifically, it is mainly manifested in the following five aspects.
Generally, single-phase inverters below 6kW and three-phase inverters below 10kW are mostly used in households. Two MPPTs are used, and each MPPT is equipped with one string. Small industrial and commercial projects generally use 20kW to 40kW inverters
Among such devices, solar inverters play a key role. This type of equipment is the main operating equipment of the equipment. Without it, the entire system cannot run.
