The choice of on grid solar inverter is a crucial part in the design and construction of photovoltaic power plants. It involves two main links:
First, the conversion efficiency of the on grid solar inverter directly affects the amount of power generation. A good inverter not only has a wide input voltage and output voltage range, but also has efficient and reliable MPPT tracking accuracy and internal circuit design. Although there are many varieties of inverters on the market, it has been proved that PV arrays with the same installed capacity use different brands of inverters, and the power generation is still very different, and some even have a gap of 5-10%.
Second, the reliability of the on grid solar inverter is very important. If the inverter is inefficient, the efficiency is zero. The previous results were completely erased due to the loss of power generation caused by the faulty repair for several days.
Therefore, in addition to the good match between the on grid solar inverter and the photovoltaic array voltage, the designer of the selected brand inverter is one of the keys to ensure the photovoltaic power generation.
