China SMC Fiberglass Photovoltaic Grid-connected Boxes - TY-SXD2-GF1 and TY-SXS2-GF1 from Reliable Suppliers and Factory
Core role
- 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, achieving a stable connection.
- SMC material provides high insulation resistance (≥20MΩ) and excellent flame retardancy (UL94 V0 level), isolating arc/short circuit risks.
- Built-in lightning protection module and overcurrent protection device resist grid fluctuations and lightning surge impacts.
- IP65 protection level and above: dustproof and waterproof sealing structure resists heavy rain and sandstorms.
- Resistant to acid/alkali corrosion and UV aging (stable operation at -40℃~+120℃) for harsh outdoor environments.
- Integrated data acquisition module monitors power generation, voltage, current and other parameters in real time.
- Supports remote fault diagnosis to reduce maintenance costs.
Core application areas
- Inverter output side of centralized ground power stations, serving as a regional grid-connected node with high-capacity components and heat-dissipating design.
- Industrial/commercial rooftop: corrosion-resistant and explosion-proof design for high-risk chemical or industrial environments.
- Agricultural-photovoltaic complementary: moisture- and heat-resistant structure suitable for agricultural greenhouses and irrigation environments.
- Offshore platforms and island microgrids: Anti-salt spray corrosion performance ensures long-term operation in humid, high-salt air.
- Desert/plateau power stations: Anti-sand sealing and wide temperature range adaptability (-40℃ extreme cold to +70℃ high temperature) ensure reliability.

Frequently Asked Questions (FAQ)
SMC (glass fiber reinforced unsaturated polyester resin) offers high insulation resistance (≥20MΩ), excellent flame retardancy (UL94 V0 level), and is lightweight. This reduces bracket load, simplifies installation, and provides a lifespan of over 30 years—making the full life cycle cost lower than traditional metal boxes.
Yes. The boxes feature an IP65 protection level with a dustproof and waterproof sealing structure. They are resistant to acid/alkali corrosion, UV aging, and operate stably within a wide temperature range of -40℃ to +120℃, making them suitable for deserts, plateaus, and coastal areas.
They feature built-in lightning protection modules, overcurrent protection devices, disconnectors, and miniature circuit breakers. These components isolate arc and short circuit risks, prevent electrical fires, and protect the system against grid fluctuations and lightning surges.
The TY-SXD2-GF1 is a single-phase multi-meter box configuration equipped with a 2P 100A disconnector and two 2P 63A miniature circuit breakers. The TY-SXS2-GF1 is a three-phase multi-meter box configuration that includes a 4P 63A small recloser, 4P 32A miniature circuit breakers, and a 4P 385V surge protector.
Yes, it features an integrated data acquisition module that monitors power generation, voltage, current, and other critical parameters in real time, supporting remote fault diagnosis to reduce overall maintenance costs.
