This series of high-power solar power supply systems is specifically designed for scenarios with high load power and long-lasting power consumption requirements. The system consists of high-efficiency solar panels, waterproof cabinets, integrated inverter and controller, and lithium batteries. It is easy to install, reducing wiring construction and solving the problems of "difficulty in obtaining power, complex construction, and high cost". It can provide stable and clean off-grid power for high-power equipment and various types of electrical loads, and is widely used in areas with difficult power supply such as data monitoring, security monitoring, forest border defense, and agricultural water conservancy. At the same time, it supports 4G networking function to meet the needs of remote communication and data transmission.
