The YHZHCH series photovoltaic grid-connected access boxes excel in product quality, craftsmanship, material selection, and production processes. They are made of high-quality cold-rolled steel plates with a plastic spray coating, which is corrosion-resistant, wear-resistant, and can withstand high and low temperatures. The protection level reaches IP55 or above, meeting the requirements for long-term outdoor use. In terms of craftsmanship, the box undergoes precise cutting, bending, and welding processes, resulting in a stable structure and refined appearance. Internally, it is equipped with dedicated photovoltaic grid-connected circuit breakers, disconnectors, miniature circuit breakers, surge protectors, and other high-quality electrical components. Its performance surpasses conventional switches, providing overcurrent, short-circuit, leakage protection, and lightning protection for power sources, along with an automatic reclosing function.
Its applications are extensive, suitable for AC 50Hz distribution systems with a rated working voltage of 380V. It plays a crucial role in connecting the AC power generated by inverters to the grid or end-users in centralized and distributed photovoltaic power generation projects, ensuring safe and stable system operation. With the growing global demand for clean energy and the promising market prospects for photovoltaic power generation, the photovoltaic grid-connected access box, as an important component of photovoltaic power generation systems, will also see greater market development opportunities.
