China DC Disconnect Switches for large solar arrays Manufacturers, Suppliers, Factory

In this release, we demonstrate how to correctly connect the LQX-C Solar DC Breaker Box. First, use the wrench and provided screws to secure the breaker box in the appropriate position. Then, use the connectors to connect the PV strings and inverters to the breaker box. Finally, follow the manual to check and confirm that all connections are secure and reliable.

Longqi New Energy is a leading provider of innovative renewable energy solutions. We take pride in presenting our flagship product, the LONQ-40 Photovoltaic Isolation Switch, which is the result of our collaboration with the internationally recognized testing and certification organization, TUV Rheinland.

Photovoltaic power generation is a technology that converts sunlight directly into electrical energy based on the principle of the photovoltaic effect.

The system's working principle is as follows: • Energy Collection: Solar panels capture sunlight and convert it into DC. • Energy Integration and Conversion: DC current is centralized through the combiner box and converted into AC by the inverter. • Safety Assurance: Isolator switches, circuit breakers, and surge protectors guarantee operational safety and system stability. • Energy Storage and Management: The battery protection box ensures safe battery charging and discharging for effective energy management.
