1.Three-Layer Design:
Top Layer: Functions as a brim to prevent rainwater from entering the box.
Middle Layer: Houses a photovoltaic metering meter visible through a transparent glass plate, with a sealing interface on the door lock for added security.
Bottom Layer: Serves as a control and protection area for easy maintenance.
2.Power Grid Inlet Hole:Designed for bottom or side entry, with an IP66 waterproof joint for side entries to maintain the box's protection level.
3.Convenient Inverter Wiring:The inverter inlet hole is located at the bottom for direct on-site wiring, streamlining installation processes.
4.High-Quality Isolation Switch:Utilizes a well-known brand with a clear breaking point and a design capacity exceeding 1.5 times the maximum output current of the inverter.
5.Voltage Protection Devices:Equipped with photovoltaic overvoltage and undervoltage protection, as well as voltage recovery reclosing protection, safeguarding against unstable power grid conditions.
6.Lightning Surge Protection:Designed with lightning surge protection featuring a standard maximum discharge current of 40kA, with options for larger protectors (up to 100kA) in areas prone to thunderstorms.
1.Modular Protection Design: Integrates photovoltaic-specific circuit breakers, overvoltage/undervoltage protection modules, and surge protective devices (SPDs) to form a comprehensive electrical protection chain. Supports flexible optional features such as meters and residual current protection, adapting to diverse grid-connection requirements.
2.All-Metal Sealed Structure: Constructed from cold-rolled steel plate or stainless steel, combined with a three-layer compartmentalized design and IP65 protection rating, effectively resists rain, dust, salt spray, and UV erosion, specifically built for harsh outdoor environments.
