Polaris solar PV net news: as we all know, PV inverter solar power generation system is the most critical component, whose main function is to collect a variable DC voltage input into AC sine wave output without interference, which can be used for the device, and can also be fed back to the power grid, which directly affect the efficiency of PV system performance as a whole. Inverter is an essential core component not only converts the direct current to alternating current, and is one of the determinants of power generating capacity, accounting for power plant with a total investment of 5%-7%.
Therefore, the inverter PV system performance for improved efficiency and reliability, improve service life and reducing cost of the system is essential.
