Adopting hot-dip galvanized steel plate, the cabinet structure is safe and reliable, with sufficient mechanical strength. The product has a series of protections such as anti islanding protection, voltage closing, voltage loss tripping, low voltage in the power grid, overvoltage in the power grid, input lightning protection, system overcurrent, and power grid isolation.
