HPPV-BWX Photovoltaic Grid-Connected Box

The HPPV-BWX Photovoltaic Grid-Connected Box is a power distribution unit engineered for solar power systems, enabling the safe and efficient transmission of DC or AC power from photovoltaic arrays to the utility grid. 

Product Advantages
Reliable Electrical Protection
Incorporates overvoltage, overcurrent, and surge protection mechanisms to safeguard system components.Offers effective electrical isolation between PV sources and the grid, improving overall operational safety.Supports both manual and automatic protection features for fault management.

Compact System Integration
Combines switching, protection, and monitoring components within one enclosure to simplify layout.Reduces the need for external devices, minimizing wiring complexity and saving space.Facilitates centralized control of power flow between PV modules and the utility grid.

Versatility and Compatibility
Compatible with a wide range of inverters and grid configurations, including single-phase and three-phase systems.Can be deployed in both AC and DC side configurations, depending on system design.Supports integration into new installations or retrofitting into existing PV setups.

Product Features
Integrated Surge and Fault Protection
Equipped with surge protection devices (SPDs) to absorb voltage spikes and protect downstream components.Includes DC or AC circuit breakers, depending on configuration, to disconnect in the event of a fault.Provides short-circuit protection to prevent damage during abnormal system conditions.

Robust Enclosure Design
Enclosure rated to IP54 or IP65, offering protection from dust, moisture, and environmental elements.Manufactured using powder-coated steel or stainless steel for enhanced durability in outdoor applications.Resistant to UV exposure and temperature fluctuations, supporting long-term outdoor operation.

Product Applications
Residential Solar Installations
Integrates rooftop PV systems with local distribution networks safely and efficiently.Provides necessary protection and switching without requiring additional panels or enclosures.Supports homeowner-friendly monitoring interfaces for energy awareness.

Commercial and Institutional Buildings
Suitable for medium-sized PV arrays installed on schools, offices, and commercial facilities.Helps manage energy flow, enabling compliance with utility interconnection standards.Assists with centralized fault detection and maintenance planning.

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
