Product OverviewThis core photovoltaic grid-connected device is responsible for boosting the inverter's AC power to 10kV/35kV for grid connection, and also provides power distribution, protection, and monitoring functions.It features a modular, integrated box design and can be installed on an outdoor pedestal, eliminating the need for a distribution room. The enclosure achieves IP54+ protection and is resistant to harsh outdoor environments.
It is optimized for photovoltaic output fluctuations, uses low-loss components to reduce energy consumption, and offers strong harmonic and short-circuit immunity. Some systems also feature intelligent remote monitoring.It is available in oil-immersed (for large centralized power stations) and dry-type (for distributed/sensitive areas), with power capacities ranging from tens to thousands of kVA, making it suitable for a wide range of photovoltaic projects.
