CNLonQcom PV Systems: An Exploration of Solar Energy Working Principles


Wenzhou Longqi New Energy Technology Co., Ltd is committed to providing integrated photovoltaic system solutions and has designed a new schematic diagram for easier customer understanding. Our technological innovations enhance the safety and efficiency of solar systems and simplify installation and maintenance processes. Here's a brief overview of how our photovoltaic system components work together to maximize solar energy conversion efficiency.

Core components of the photovoltaic system include:

• Solar Panels: The base of energy collection, converting sunlight into direct current (DC) to power the system.

Solar Connectors: Ensure a safe and effective connection between solar panels and the rest of the system, enabling smooth energy transfer.

PV Isolator Switch: Safely disconnects the power supply between the solar panels and the combiner box, protecting maintenance personnel from electrical hazards.

DC Combiner Box: Consolidates the electrical energy generated by multiple solar panels for delivery to the inverter.

• Inverter: Converts DC into alternating current (AC) for residential use or grid feed-in.

DC Circuit Breakers (MCB/MCCB): Automatically cut off power in the event of an overload or short circuit, preventing electrical fires and equipment damage.

DC Surge Protectors (SPD): Shield the system against voltage surges, including those caused by lightning strikes, ensuring stable operation.

• Battery Protection Box: Secures the battery pack storing excess electrical energy.

Additionally, the system includes an AC distribution box (AC Box) containing AC circuit breakers, residual current circuit breakers (RCCB), and AC molded case circuit breakers (MCCB), assuring the system's integrity and safety.

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.

At CNLonQcom, we lead the industry with our highly integrated PV system solutions, offering global users safe, reliable, and eco-friendly energy conversion options. Our technology and product coherence, along with our attention to detail, ensure the stable operation of PV systems across various environments and optimize solar energy utilization.
