SDEV Charger
1 / 5
GD-PV4/1 PV combiner box facilitates the synthetic DC input of 4 PV components into 1 output. Each channel is equipped with a high-performance fuse, while the output side features comprehensive lightning protection and a circuit breaker.
This system significantly simplifies the input wiring for DC power distribution cabinets and inverters, providing robust lightning protection, short circuit protection, and grounding protection. The unit adopts an outdoor wall-mounted design, specifically engineered to adapt to harsh environments with an IP65/IP66 protection grade.
