Dear Customer: I am the head of this product series and also serve as the company manager. You can contact me for more discount offers and updates on new products. I can arrange product operation training to ensure you can use the product quickly and efficiently. Here is my contact information. Please be sure to contact me before placing an order to confirm the accurate quotation, which includes detailed information such as transportation and shipping costs. Business Card Information: Manager: Olivia WhatsApp:+86 15084860893 Email: qianruiolivia@gmail.com The platform has many shipping restrictions and strict requirements for the weight and volume of goods. Any items that exceed the weight or volume limits cannot be shipped normally. Under the international trade terms with legal binding force (FOB/CIF/DAP/DDP/EXW), we offer the following transportation options. The platform only supports air transportation, which has a relatively high overall transportation cost. We have our own channels, and the transportation cost is 30% lower than the market average. Therefore, the product prices cannot be directly calculated based on the platform’s standard. Before placing an order, please verify the transportation method and service of the goods to avoid delays caused by inability to ship.

Description
For large-scale PV grid-connected power generation system, in order to reduce the connection between the PV module and the inverter, and to facilitate maintenance to improve reliability,it generally need to add DC busbar device between the PV module and the inverter. Our company’s PV array lightning protection combiner box is designed to meet this requirement and can be designed to a complete PV power generation system solution with PV inverter products. Using PV combiner box, the user can put certain number of same specifications PV modules into series PV module according to input DC voltage range of the inverter, and then a number of series PV modules access to the PV array lightning protection box.It’s convenient to facilitate the post-inverter through the output for lightning protection device and circuit breaker.
The PV array lightning protection box has the following characteristics:
(1) meet the requirements of outdoor installation, protection class IP65/IP66, with anti-UV, anti-acid, anti-alkali, moisture, mildew, rodent control and other functions;
(2) access 4-way PV array, each with 15A, 1000Vdc fuse (replaceable other grades);
(3) Equipped with special high-voltage lightning protection device, lightning protection function with cathode and anode ;
(4) Positive, negative string into the fuse;
(5) Use quadruple PV dedicated circuit breaker with positive and negative in series;
