BWX Photovoltaic Grid-Connected Box

All metal enclosures are made of cold-rolled steel plate or stainless steel plate, with a protection rating of IP54 or higher, suitable for outdoor installation. The enclosure adopts a three-layer design: the top layer serves as a brim to prevent rainwater from entering; the middle layer houses the photovoltaic metering meter, allowing data observation through a transparent glass panel, and includes a seal interface on the door lock; the bottom layer is designed for control and protection, facilitating maintenance and inspection.

  • Fully Custom
  • Expedited Production Processing

Product Advantages:

1.The isolation switch inside the enclosure uses renowned brands, features visible disconnection points, and is rated for 1.5 times the maximum output current of the inverter.
2.Equipped with photovoltaic over/under voltage protection and voltage recovery reclosing protection devices, it safeguards against grid voltage instability in addition to loss of voltage protection.
3.The enclosure includes lightning surge protection, with a standard maximum discharge current of 40KA. For areas with frequent thunderstorms, larger surge protectors with a maximum discharge current of up to 100KA can be selected.
4.Designed with an overcurrent protection circuit breaker to ensure reliable tripping during system overload or short circuits.
5.The internal mounting plate can be configured with an epoxy resin insulation board (minimum 5mm thickness) as per customer requirements.
6.Anti-islanding protection devices can be configured based on customer needs.
