1500V high-voltage components and corollary electrical equipment mean lower system cost and higher power generation efficiency, which will soon become the new favorite of the photovoltaic industry.

After the DC side input voltage is increased, more components can be connected per string, which can increase the string length by 50%. The DC cable used in the inverter is reduced, and the number of inverter and combiner boxes can be reduced accordingly. At the same time, the power density of the combiner box, inverter, transformer and other energy equipment is increased, the volume is reduced, and the workload in transportation and maintenance is also reduced, which is beneficial to the reduction of the cost of the photovoltaic system.

From a system point of view, higher input and output voltage levels can reduce AC/DC side line looses and transformer low-voltage side expected to be increased by 1.5-2%
