PV grid-connection (box) cabinet

Product Overview

The PV grid-connected (box) cabinet is a vital power protection component for photovoltaic series-connected power generation systems, which connects the series-connected inverter and the power grid system. The circuit protection part adopts a PV grid-connected circuit breaker and a pull ring isolation switch, along with secondary lightning protection. It also has multiple protection measures, including overload, overcurrent, short circuit, leakage, overvoltage, undervoltage, to ensure the safe and effective operation of the system. The device can also be equipped with communication function according to customer requirements, achieving remote monitoring and management of photovoltaic power generation systems, improving the intelligence level of the product. The protection level is equivalent to IP65, the same as the series-connected inverter, meeting the requirements for outdoor installation, including being waterproof, dustproof, UV-resistant, and corrosion-resistant against salt spray. The internal structure of the product is simple and clear, with neat and reasonable wiring, high reliability, and easy maintenance, adaptable to various harsh environments.

PV distribution cabinet is an important part of the current development of the solar photovoltaic industry. The product not only meets the market demands but also promotes the society towards the direction of green, low-carbon and sustainable development. As a high-end enterprise with technological innovation, product quality and service level, we will continue to provide high-quality products and services to our users and make our due contribution to the development of the industry.
