1. Selection of reliable suppliers
Assessing Qualification & Experience: Scrutinize the supplier's credentials and production expertise, opting for one with an impeccable reputation and extensive practical knowledge.
Ensuring Seamless After-Sales: Clarify contractual terms regarding post-purchase support and penalties for non-compliance, guaranteeing prompt technical assistance and maintenance throughout the usage period.
2. Transformer Applications in Renewable Energy
Photovoltaic Power Generation System: A photovoltaic power generation system converts the direct current (DC) produced by solar panels into alternating current (AC) using an inverter. After this conversion, a transformer increases the voltage to levels appropriate for the grid, such as 220V or 380V. This process ensures that power can be safely and efficiently transmitted to the grid, accommodating the diverse needs of various users.
Grid-connected systems: In a grid-connected photovoltaic system, the transformer plays a crucial role in linking the generated power to the grid, thus maintaining a stable and reliable electricity supply. It also provides electrical isolation, safeguarding the photovoltaic system from potential faults in the grid.
