Product advantages
●All metal boxes are made of cold-rolled steel plates or stainless steel plates, with a protection level of IP54 or above, suitable for outdoor installation
●The box adopts a three-layer design, with the top layer designed as the brim of the box to prevent rainwater from entering the box during raining; the middle laver is designed as a photovoltaic metering meter, and various data on the meter can be observed through a transparent glass plate, and a sealing interface is designed on' the door lock; the bottom layer is designed as a control and protection area, which is convenient for maintenance personnel to maintain and repair
●The power grid inlet hole in the box is designed to be entered from the bottom or the side. When entering from the side, an IP66 waterproof joint is installed to ensure the protection level of the box
●The inverter inlet hole of the box is designed at the bottom, making it convenient for direct on-site wiring
●The isolation switch inside the box adopts a well-known brand and has a clear breaking point. The designed capacity is more than 1.5 times the maximum output current of the inverter
●The box is designed with photovoltaic overvoltage and undervoltage protection device and voltage recovery reclosing protection device. In addition to voltage loss protection, this product can also protect the unstable voltage of the power grid
●The box design has lightning surge protection, and the standard maximum discharge current of the surge protective device is 40KA. In areas with frequent thunderstorms, larger lightning surge protectors can be selected, and the maximum discharge current can reach 100KA
●The box is designed with overcurrent protection circuit breaker, ensuring that the circuit breaker can reliably open in case of overload and short circuit in the system
●The mounting plate inside the box can be equipped with epoxy resin insulation board according to customer requirements, and the thickness of thel insulation board should be at least 5mm or more
●Anti islanding devices can be configured according to customer requirements
