· Reduce input costs
Stringing more modules: Reducing the number of inverters, convergence boxes, and other electrical products reduces the initial investment cost, which saves the overall BOS cost (system cost other than PV modules) and LCOE cost (average cost per unit of electricity).
Reduced transmission system cost: The higher the current, the thicker the wire required and the more material used. Therefore, by increasing the voltage, the current is lowered and the amount of material used is saved.
Reduced O&M costs: the system power density is increased, the size is reduced; the number of electrical products is reduced, and the number of points of failure is reduced. Ultimately, it greatly saves the consumption of labor and material resources in transportation and maintenance.
· Enhancement of utilization efficiency
Reduced line loss: Higher input and output voltage levels can reduce current and heat generation, which helps to reduce line loss on the AC and DC sides and improve utilization efficiency.
Environmental weather resistance: It can be adapted to long-term permanent use in outdoor changing and harsh weather conditions.
