The photovoltaic grid-connected cabinet is suitable for power users such as ground centralized, ground string-type, and ground distributed systems, with AC 50Hz, rated operating voltage of 380V, and rated operating current of 2000A distribution systems. It is used for power conversion, distribution, and control in power, lighting, and distribution equipment.

The product features high breaking capacity, good electrodynamic and thermal stability, flexible electrical schemes, convenient combination, strong practicality, novel structure, and high protection level. It can be used as an upgraded replacement for low-voltage complete switchgear.

• Worry-free: High degree of automation, can operate stably for long periods without human intervention.
• Flexible: The number of AC (inverter) input lines can be designed as multiple lines according to actual conditions.
• Safe: Equipped with multiple protection functions such as undervoltage trip detection, overvoltage closure detection, surge protector, and islanding protection.
• Reliable: Can be matched with components from well-known domestic and foreign brands according to customer requirements.
• Advanced: Uses technologies such as permanent magnet control, microcomputer protection fast algorithms, and high-speed signal processing.
• Intelligent: Can collect voltage, current, frequency, active power, and reactive power; can perform four-quadrant energy measurement; and uses the ModBus-RTU communication protocol to achieve local/remote data monitoring via RS485 communication interface.
