China SMC Fiberglass Photovoltaic Grid-connected Box Manufacturers, Factories
Product Description
Core Role
1. Power Confluence and Transmission Center
The DC power output by the centralized photovoltaic array is converted into AC power through the built-in inverter and then connected to the power grid or supplied to the load, thus achieving a stable connection between the photovoltaic power generation system and the power grid.
2. Multiple Electrical Safety Protections
- The use of SMC material (glass fiber reinforced unsaturated polyester resin) provides high insulation resistance (≥20MΩ) and excellent flame retardancy (UL94 V0 level), effectively isolating arc and short circuit risks and preventing electrical fires.
- Built-in lightning protection module and overcurrent protection device can resist power grid fluctuations and lightning surge impacts to ensure the safety of equipment and personnel.
3. Environmental Adaptability Protection
- The box has an IP65 protection level and above, and the dustproof and waterproof sealing structure can resist heavy rain and sandstorms.
- It is resistant to acid and alkali corrosion and UV aging (stable operation at -40℃~+120℃), and can adapt to harsh outdoor environments such as salt spray and industrial waste gas.
4. Operation and Monitoring Support
The integrated data acquisition module monitors power generation, voltage, current and other parameters in real time, supports remote fault diagnosis and reduces maintenance costs.
Core Application Areas
1. Large Photovoltaic Power Station
The inverter output side of the centralized ground power station, as a regional grid-connected node, needs to be matched with high-capacity electrical components and dust-proof and heat-dissipating design.
2. Distributed Photovoltaic System
- Industrial plant/commercial building rooftop power station: The corrosion-resistant box adapts to the industrial exhaust gas environment, and the explosion-proof design meets the requirements of high-risk places such as chemical industry.
- Agricultural-photovoltaic complementary project: The moisture- and heat-resistant structure is suitable for installation on the top of agricultural greenhouses and is compatible with irrigation water vapor environments.
3. Coastal and Humid Areas
Offshore platforms and island microgrids: Anti-salt spray corrosion performance ensures long-term operation in humid and high-salt air.
4. Special Climate Areas
Desert/plateau power stations: Anti-sand sealing and wide temperature range adaptability (such as -40℃ extreme cold or +70℃ high temperature) ensure equipment reliability.
