Product Overview
The GGD type PV grid-connected cabinet serves as the main export of the photovoltaic power station, connecting the PV station to the power grid as the boundary point between the PV generation system and the grid. It is a key component connecting the centralized inverter or AC combiner box with the step-up power grid transformer. The incoming line can be connected via a circuit breaker or directly, and the output via a circuit breaker or load isolation switch; busbars are connected with tin/silver plating, and secondary lightning protection is provided. With IP40 for indoor use and IP65 for outdoor use, additional functions such as metering, protection and remote control can be added upon customer requirements. The product features a simple, safe and aesthetically pleasing structure, facilitating on-site wiring and maintenance and ensuring long-term stable operation.

Operating Environment
- Ambient temperature: Shall not exceed +40℃ or fall below -20℃, with an average temperature within 24 hours not exceeding +35℃. If these limits are exceeded, the operating capacity shall be adjusted according to the actual situation.
- Relative humidity: The air shall be clean, with relative humidity not exceeding 70% at the highest temperature of +40℃. Higher relative humidity is allowed at lower temperatures, with occasional moderate condensation to be considered due to temperature fluctuations.
- Altitude: Shall not exceed 3000m.
- Transport and storage: Suitable within a temperature range of -25℃ to +55℃, with short-term exposure (not exceeding 24 hours) up to +70℃. Irreversible damage shall be avoided at these extreme temperatures, and the device shall function normally under normal conditions.
- Installation conditions: The vertical installation slope shall not exceed 5°.
- Environmental media: No explosive hazardous substances, and the medium shall not contain gases and dust that can corrode metals or damage insulation.
- Note: If the above operating conditions cannot be met, the user and the manufacturer should negotiate to resolve the issue.
