A micro-grid system is formed by combining both wind and solar energy storage devices, which adopts the DC coupling mode to facilitate energy conversion rate. Our products offer a solution to power shortage issues in areas that are beyond the reach of power grids. This series of products features an integral container design, which is extendable and easy to move around. The solar panels are engineered to be able to move in and out of the cabinet automatically, and so are the wind turbines that adopt an automatic lifting system and thus can retract or lift automatically according to weather forecasts, maximizing the utilization of wind and solar power and ensuring the safety of devices. The combination of local management of micro-grid-generated power, control by 4G cloud tech and a mobile APP makes the device more intelligent, and enables real-time presentation of data remotely, hence facilitating system operation and maintenance.
